Title: What Did You Do Airplane Wise Today?
Post by: DerekMc on August 31, 2017, 11:41:16 AM
There is a fun thread on a rocketry forum I read called 'What did you do rocket wise today.'  It's amazing the breadth of peoples projects and activities. I don't know of a similar thread on Hippocket so here goes.

What Did You Do Airplane Wise Today?

If it has to do with aeromodelling (as defined by you) why not post a picture or two?

I'll go first.  I'm figuring out how to connect an RDT unit and flashing LED to a F1B (Wakefield). The connectors are all there but it is a tight fit. Where would the flashing LED be most visible? Top (safer) or bottom (hits ground)?  Still workin it all out.

Whose next? :)

You caught me right in the middle of trying to find some information on actuators.  What size do I need for a given control surface size or plane size.

Went flying - and finally got a rubber scale model to stay up for over a minute!  https://youtu.be/QNeriOgeevM (https://youtu.be/QNeriOgeevM)

Also did some more trimming on the peanut Little Gem racer - making progress, more work to do...  https://www.youtube.com/watch?v=h8Z1zje57kQ (https://www.youtube.com/watch?v=h8Z1zje57kQ)

Really nice morning here in San Antonio.  Spare a prayer for those east of us dealing with all the water.

Cheers,

Cut some 3mm strips of 3M Transpore tape (the stuff with a slightly pimply surface) to use as a turbulator on a wing covered with what I suspect is too smooth ProFilm Lite.

Kite flying is cool!
Some interesting stuff happening.  I was successful hooking up the RDT on the F1B. Kind of hard because the connection is blind.  The connector is inside the pylon and impossible to see when you try to insert the RDT unit. It' all about feel. Replaced the Instant Prop Release cable which had frayed a bit as well.  Plane is read for the contest a week from now.

Ha, Ha!  I feel your pain. It is challenging waiting for the right conditions when you have a new plane which you are excited about! Truly a time when patience is a virtue, as challenging as that is! How about a picture or two of your sailplane in the meantime?

Sweet! Mike, nice looking airplanes and some nice flights.  Looks like you caught a nice little thermal on the first flight in the first video.  Looks like your plane was joined by a couple of swallows. Swallows are a great thermal indicator where we fly outside of Tangent, OR.  If you see the swallows swooping overhead, LAUNCH!

A week's end-of-summer break in a rental cottage in Snape, with woman, kid, dog, bicycles. Huge self-catering fun. Rented a Canadian canoe on the Alde, knocked about art galleries and craft shops (where a particular VMC Camel kit was purchased!), long estuary walks, bike rides on bridleways, a spot of bird-watching, studying a boatbuilding book (an 8ft traditional clinker/lapstrake pram dinghy in epoxied plywood is my next full-scale project), and much general -purpose indolence!  :D

Went to Buckminster today, to join up with two GDMAS mates. The site is now well signed by the road. Manny wasn't there - the field was in the hands of some radio fliers who were camping - at least one of them had been providing volunteer help for the Nationals. The guys I met were friendly.

There was a mown track down from the car park to the two circles. We drove down and parked close to the larger circle.

There has been massive progress since I saw the site in early May. There are two close mown circles -I measured them at 123 ft and 140 ft diameter. I got the impression that the larger circle was more level. It was a good circle to fly from. You can get an impression of the grass length from the close-up picture of my Cardinal. You wouldn't want to drop a stunter down in the long grass though - see the picture of my mates sitting in their chairs. The windsock was in a handy position for both radio and control line.

There was little turbulence - but then there was little wind.

A very enjoyable day.

Thanks!  We get a lot of swallows at our field, but they mostly chase the airplanes rather than showing the lift.  They get particularly perturbed by the jet-cats - I guess they think the gliders are competitors or predators.  One morning I had a couple dozen barn swallows chasing my Scimitar jet-cat.

I'm preparing for a Free Flight contest nest weekend. I chase my planes with a Yamaha Y80. Works great for what I do. Every once in a while I forget to take my radio reciever so I have to go back for it if I lose sight of my plane.  I decided to add a handlebar bag to the bike so the radio and a bottle of water is always ready to go. I found a nice bike handlebar bag for sale that looked like it would fit.  Looks like it  will work well. A nice feature is that it is removable. There's room for a pair of backpacking binoculars for scanning the field if there is need.

I am intrigued with the idea of chasing models a motorbike.  It would just not be practical here in England.  We use pedal cycles on some airfields but otherwise it is shank's pony!

But it keeps us fit!

As a matter of interest  can you give a rough guesstimate of how far you travel on your motorcycle for the average retrieval.  I imagine you see that you are flying in the middle of a prairie with nothing for hundreds of miles!

I'm not sure how far I travel.  The attached picture is a google satellite image of the flying site:  Parker Field in Tangent, Oregon.  We fly on harvested grass seed fields which go on for miles. Lot's of roads and edge of field obstacles that can catch up one's plane. Most flights are trouble free though. There is a lot of open room.
The yellow lines were typical flights I had flying my E36 with it's two minute max at the last contest. There was a bit of wind so most of the flights crossed the road at the end of the field. I eyeballed the scale so it's approximately 3000 ft. to the road.  The longest flights were close to a mile?  At a typical 2-3 event contest day I would say there would be 12-15 retrievals, maybe 5-7 miles depending on wind speed and required max?

Fixed an F1B wing over the last week or so. About a 1/4" of the wingtip hit a power pole during a test flight and popped it off. At least the plane fell into some tall weeds so the wing was the extent of the damage.

A bit of glue and carbon tissue reinforcement and it was ready for covering. I used Cover Grip to attach Polyspan. It worked well. Will thin it down a bit more next go around so that it spreads better. Applied the Polyspan, shrunk it and then sealed with Eze-Dope which worked great. Just about ready to spray the patch with Design Master spray paint.  Will be ready to fly in the contest this weekend. 8)

Unpacked the van after a fun contest in Tangent, OR.  I'm charging/discharging my E36/ F1S batteries to their proper storage level.  Then going over my planes to make sure they are in fine shape for the next contest.  I attached a picture of me cranking in hand turns waiting for a thermal in Friday's Tangent FAI Classic.  Fun contest!

And to make things a little bit more complicated I still dream to make a short torque meter, sort of radial, spiral spring. But dont know how.

Urs
If you take apart an old, pull start lawn mower, snow blower, etc. you will likely find a spiral spring setup to copy. Depending on just how much torque you use, maybe you can just adapt the whole thing. DON'T take it apart if you need to use it soon for its original purpose. These things can be tricky to get back together. There might be some friction, so keep everything lubed up.

Thank you for that Derek - comprehensive answer!  On occasions I have covered by walking in the region of 6 miles (according to the app on my iPhone) but I hasten to add not my own models - helping others whose models fly better.  That looks some flying site. I do not think we have anything like that here apart from as it so happens a local to me airfield of 1000 acres plus but not always available.  The main runway is 2 miles long.  Not entirely unusual for models to go outside the fence.

Nothing today, but on Sunday I went to the field and discovered it was full of miniature soccer players*, who tend to appear on all large, flat, grassy surfaces. The alternate field had full sized cricket players, though I think maybe there was room for flying too. I didn't want to push it.

Very well put - but to keep on topic this site demonstrates that aeromodellers are very diverse and could not really be described as conformists, regardless of size. There are many varied disciplines practised by different people from all classes.

Took a break from building the Tigercat today and went flying.  Got some promising results from continued trimming of the Little Gem peanut, played with a longer motor for the Tempest, enjoyed the slow cruise of the Waco, caught some nice air with the peanut Zippy Sport and finished off with some jetcat and hand launch gliders.  Great weather - just a nice day to be out flying.

Both maxes were first for me in the respective classes. I'm either getting better, or luckier. Probably a little of both!  ;D

Looking at the works of Mike Kelly, Flyguy, Prosper, Don McLellan and other wizards on here has inspired me to pull out my long bench-stalled Piper Navajo Cheiftain. I really don't have far to go here. I am thinking about using thin mylar on the fuse and cover with Esaki because of the glasswork in the cabin area. I may have to use a Peck kit to prime the pumps though. How dry I am!

I attached the RDT pigtail to a Black Magic Timer in a Wakefield (F1B).  I'm not that great at soldering and thought I had fried the timer when I plugged the battery in. Turns out that I miscounted and missed the right prong. Everything worked fine once I hooked it all up right.  ::) My soldering is improving...

Kept right at it while I had the soldering gear out. Replaced the battery in a Starlink band burner timer. The original batteries were quite small and didn't last long. I replaced mine with a small connector so I can switch batteries in a snap. Not the smallest/ lightest solution but it will work for what I intend.

Jim, try using the ball grinder with your dremel set. It will cut better in one direction than the other. Mike I am with Hepcat...because I bought all the tiny delrin screws and such and they sit in a small pile in the corner of my bench because I was too foggy on how to do it. It was gonna be for my Piper twin.

Post by: MKelly on September 28, 2017, 01:40:15 PM
Thanks all for the comments on the Tigercat's tail.  I've added an upright behind the fin spar and will slit the tissue there so I can insert a screwdriver for adjustments (see pics).  This stab adjuster is similar to what I did on my Tempest and Waco, but a little more complex with the rods and split stab. 

Going from the kit stab to a 10% larger adjustable stab cost me about .8g at the wrong end of the airplane (see bones pics for comparison).  Overall weight is now 40.3g, props and noseblocks will add another 10-12 g but should bring the balance pretty close.  Target weight for .5g/sq in is about 57g - I expect with covering I'll end up a bit over.

Very, very nice Mike.  And have to ask, how did you do it?  I always thought installing silver Esaki wrinkle free was impossible.


Title: Re: What Did You Do Airplane Wise Today?
Post by: MKelly on October 01, 2017, 10:17:55 PM
Thanks guys.

Don, it's far from wrinkle-free.  The silver went on pretty well over the stringered portion of the nacelle, but the infilled cowls were a chore.  All was covered wet (water/alcohol spray and glue stick adhesive).  The cowls were broken up into three sections - single ring at the aft where the cowl flaps are, then two half-rings to cover the front end, followed by a single ring covering between the two.  I used a cone calculator to estimate the arcs of tissue for each section, made templates based on that to cut the arcs, then tugged and swore and peeled it off and tried again until I decided it was good enough.  The camera is kind - up close there's a few spots that look like I covered the cowls with gum wrappers.

Removed the twist from the tailboom of my Elf dlg. Also glued stab back on.

This particular Elf, at least, had the pushrods on the outside of the tailboom, supported by short sections of tube glued to the tail boom every couple of inches. When heating to untwist it, I put a clothespin over each bit of tube to keep the heat from softening the glue that held it on. I couldn't find my heat gun, so I used a candle. Will have to clean well if I need to glue something to it in the future.

Building a new Hangar Rat wing - experimented successfully with formed ribs.  Soaked the wood in cloudy ammonia, clamped it to the rib block form and baked it in the oven for 30 minutes at 100 degrees C.   Front and rear faces of the ribs sanded into the blank while it was still sitting on the form, using my table sander.  sliced the ribs off at 1/32 intervals using my balsa stripper.  Very easy, very successful,  and much stronger than the usual sliced rib.

Mentioned my latest Hangar Rat back in reply #94 with the formed ribs.  Flew it at a comp on the weekend.  She weighs 3.6g and we did 4:11 on 1800 turns .063" .  I'm confident there's more to come.  My S-hook was bent in a hurry at the last minute and was off centre,  with the imbalance certainly wasting energy.  I'l fix that before I fly next.   Pretty sure she'll go on .058 or even less,  which will mean less weight and more turns...  Very confident that we can crack 5 minutes

Put the trim on the Tigercat's fuselage.  Black lines are sliced from Peck domestic tissue and applied using glue-stick and rubbing alcohol.  First time I've attempted this technique - other than being tedious it went better than I thought it would.  A few panel lines on the silver sections and it'll be ready for dope.

Thanks Mike - no printed tissue on this model - everything is cut from red/white/silver esaki and trimmed with strips of black domestic tissue.  Kit is the Diels Engineering 1/24th scale F7F (25.5" span).  The kit is out of production but Diels still sells the plan and canopy.

Went to see the new seal pups at Donna Nook, North Lincs. Wasn't meant to be an aeroplane related trip, but this Miles Gemini flew over them and buzzed about a bit, quite low, which was quite a bonus. I didn't take the plane photo, but it was close enough to clock the reg and look it up later. (Seals didn't seem bothered at all. Not a bad life- loafing in the sun with a nice layer of blubber to keep out the cold.)

It is a nice looking aircraft. Think I'll try something a bit simpler whenever I attempt my first twin though.
Looks a good museum, Jon- I'll put it on my list too I think.

Monz- you've been a lot busier than the seals. They weren't doing any work at all- not even the kind you can do sitting at a screen, the lazy so-and-sos. A bit of flipper waving and the very occasional bout of flopping along to another bit of mud, and that was about it. (Mind you, apparently the dominant bull seals have to go without food for six weeks so they can stay ashore and mate with as many females as possible whilst fighting off their rivals, so I suppose they had good reason to look a bit knackered.)

Get this though- as we approached the car park we had Radio 2 on, and what song was it? 'Smile' sung by Seal!

Well I did some of this today - felt like doing a Bostonian but got distracted (as is frequently my wont) by the more scale looking types.  Hence it is, like everything I build, getting heavy. On the scales is the airframe including the u/c but no motor.  Now assuming that the finished weight will be 14gms. X 2 or thereabouts (28gms.) which is twice the minimum weight for a Bostonian, the wing loading - area 48 square ins - is not going to be low!! Assuming my arithmetic is right.  Yes there is a fair bit of timber in this model - I was as selective as I know how to be (i.e. not much) and have not added anything but it does seem building light is an elusive goal. So nuts - the model will weigh what it weighs and that is it.  However I will henceforth use the ignore button on anyone who posts a model with weight that for me is unachievable e.g.  0.5gms per square inch or less.

Thank you Russ - that is quite reassuring in fact.  It is not so much that I am. desperate to build a light model and get long duration but the frustration of seemingly being so far away from most others.  But now I think what the hell.  I need personally to be content with what I have built and hence the preference for semi scale and a fancy finish. Yes I know some folk can build superbly finished accurate scale models weighing a gramme or three but I accept that the same as
I accept some folk can run a mile in four minutes.  So thank you old chum.  I am now continuing with my Boston with gay abandon.  **!!§$€  the ounces.

We attended the BMFA Dinner last night  Very surprised and pleased to find Stan Mauger had travelled from New Zealand to lay his hands (briefly) on the Superscale Trophy which he won at the Nationals!
Other FF scale winners here, from L to R are  3 Gareth Tilston (electric/CO2) 4 Stan  5 Mike Stuart (Indoor Rubber and Coates trophy) and 6 Andy Sephton (Outdoor rubber)

PS the lady with Stan, handing out the gongs, is the wife of the main speaker, who has built a full size Bristol Scout. I meant to corner him and ask if he had any insight on why model Scouts never take off!

This morning, here in 'East Calif.', the fog was thick as soup. I opened the box from RC Specialties, (drop-shipped directly from SIG) their beautiful Monocoupe, 24" W.S., maybe electric? Maybe, but probably rubber...

My Joulebox 190 E36/F1S flies well. Just making sure the new one mirrors the first. Looks like it matches. The wing will be a bit stiffer to handle the extra speed of the 7x6 folder. At least that’s the hope!

I'm preparing to cover the wings of my Joulebox E36 with tissue over mylar..  I like printing all the numbers and other fun stuff right onto the tissue before I apply it to the mylar. We have a new printer since the last time I printed on tissue so I made a practice run.  I use a repositionable spray adhesive to lightly attach the tissue to regular bond paper.  I bought a can of loctitie spray that says its repositionable. It is but it's to sticky.  The printing worked on the tissue but I will pick up a lot tack reposinatoble spray later today.

The fun part of using MS Word or publisher is all the graphic effects you can use. I tried a reflection and it came out okay.  I always print the numbers as a mirror image and then apply the tissue as normal with the printed side down so that the text looks normal.  I've never had any issue with the toner bleeding or running.

Re trimmed class A Jay's Bird that I folded the wing on at the Nats (AFTER 3 maxes) testing 6 second engine run with short DT...DAAA TOO short!! Flew pretty good. Got out class B Provincial with Green Head 201 that I had never run. Not bad ,kept feeding a little incidence into it and left thrust ...got it going pretty good. Got out the modified Satelite 450 with the Conquest 15 which all all over the sky in Muncie. Two perfect test flights and put it away...Have no clue what it was doing at the Nats other than it was the Nats!
Soooo for me, a 3 for 3 flying session makes for a fun drive home.

Three days ago, I spent 4 hours testing and tuning the new "AMA Alpha" rubber powered plane.  I was in a low ceiling gym so I had to keep it controlled.  Best time with 1500 turns on the supplied rubber was 42 seconds.  All up weight was 16 grams.  A friend also worked with his outdoors, and later made some mods to get the weight down to 11.5 grams.  Looks like a minute flight is in the future.  The plane comes with a 20 to 1 winder that is actually quite nice, and a true bargin for the price of the entire package.

One is targeted .... the other two are more 'serendipitous'!  :)
The small one is a Fairey Fulmar... ish .... the same as the plan, but a little sharper than some aircraft show.
The other is pretty good for a model I have started drawing .... the mould is from sycamore and was mounted on a small spindle.
I couldn't get it as sharp as required without the spindle breaking (ask me how I know) with my laziness in using blunt tools and laziness in not upping the lathe speed  ::)
The sharper one is what I was shooting for! Having said that, the actual aircraft's spinner has more of a 'kick' in the shape that I do not care for! ... so I toned it down.

I've been testing transmitter and receiver batteries for my RC models. I have a feeling I'll be buying more soon. Maybe I'll go to Eneloops ($ ouch). I gather they're supposed to last a long time. I've found that age has only a weak correlation with battery condition. I've had them go bad at 2 years and at 12.

Must admit I find Enloops pretty good and worth the extra loot.

Nice spinners Russ - so is a Fulmar a project - odd coincidence but I came across a plastic kit for one and thought it might be a good choice for a FF model - have given the plastic kit away incidentally to a chap doing some decorating for us.

Russ, I bought the Middle Phase kit at least four years ago as a RE only trainer, but then started slope soaring with a foam Libelle with ailerons, which is fun but really too lightly loaded for usual conditions (and being an ARTF foamie gives me no pleasure in the model itself).  So I purchased the optional aileron wings set for the MP direct from Chris Foss, and then still did nothing!  Until now.  Will post the odd progress pic as I go along.  :)

After I saw MKelly’s Navion on this thread and vowing to build one, please see the attached of my efforts so far.

The plan had all the parts on anseperate PDF so all I had tomdo was print them and glue-em on to sheet and cut

13grams so far and going to add the landing gear on this one. Great result with Ezedope water and rubbing alcohol mix for shrinking and coating. Seems to give a much better finish than just water and Ezedope

Title: Re: What Did You Do Airplane Wise Today?
Post by: MKelly on January 07, 2018, 08:00:10 PM
Your Navion is looking great DP!  Two lessons learned from my build - may want to reinforce the stringers immediately above the TE of the wing (I put my thumb through the side there during a launch yesterday) and recommend clearancing the second former and upper keel in the cowl area so the motor doesn't bind there.

This is a great-flying model - had two flights over 1 minute duration on its second day flying.

Cheers,

Mike

John- I mixed rubbing alc, water and eze all together 50-25-25% roughly. Still lots of learning to do with this shrinking coating game. Like ezedope as its quite waterproof. Eliminates sagging in damp.

Got my magnetic building board up and running.  Picture below.

As mentioned somewhere above the metal sheet is 2mm thick 2ft by 1ft.  I mounted it on a piece of 3/8th MDF which makes it slightly easier to pick up. It is slightly heavy and thereby won't slide about easily. 

That was all straightforward and I took a guess on the magnets, not being fully aware of the size and amount of "pull" required.  However beginners luck and all that because I settled for two sizes - the square ones are 19x19x5mm with a pull of 0.46kg.  I think they will do for most jobs.  The rectangular ones are 25x10x6mm and have a pull of 0.8kg.  Noticeably stronger.  Th balsa is medium hard 1/8th square and you can see they hold the bend well although in practice I would rarely bend a piece  "dry"  like that, it would be steamed or soaked etc.

Playing with it for a short while I can see the appeal, much quicker than pins, no holes or indentations  and the magnets can be slid about if you want to alter the position.  I am a bit "messy" and tend to drop glue and dope etc. on the board I may be using because I am careless - cleaning such things off this board should be a pice of cake.

Cost wise I cannot complain.  The mild steel sheet cost three pounds including cutting and the magnets (from first 4magnets) were about ten pounds. I bought the two packs and they total 40 in all.  Probably more than I need but I hate not having enough.  Anyway not a costly asset I suggest. 

I would consider that anything much bigger than 2x1 for the "board" (and anything thicker then 2mm) might be a bit heavy to move about.

Now to build something.

Spent time in Mallorca flying a chuck glider with grandson. What is it with five year olds that they don´t understand balancing the turn with a banked launch? Mallorca has many attributes but is totally hopeless for FF. You can´t go 20 yards in any direction without striking a tree, wall or goat. And locals seem bemused by a grown man poking at a tree with a long stick.

Good am David, Good to see you with a magnet building board. The Mag board solved a lot of problems for me. One thing I wonder is why more guys haven't tried the 1/2" magnetic strip. It is cheap and comes in rolls. It can also hold a nice curve for times when nice curved longerons are needed. Give it a try oh, one side has release paper and is adhesive as well. It is magnetic enough to hold yet not so strong, you can fairly easily pick it off the board. Enough. Anyway I have my magnet board standing up so I can work standing without stressing my neck and shoulders.

Got home after three weeks, keen to stick some bits together. I was rummaging at a bookcase, on top of which were extra books and a new model on top of that. They slid off. Now, that fraud Galileo would have us believe that objects fall at the same rate, and so the model should have landed on the books. Not so. But at least I now have some bits to stick together - about 40 I estimate.

To be fair to Galileo, he demonstrated his theory with two pieces of fruit didn't he? (Rather than something which flies and something that doesn't.)... But if your new model has a faster sink rate than a pile of books, are you sure it's worth repairing?

I finally repaired a 20-year-old Guillows Fairchild.  In the same vein as above, one side had been crushed when it was nearly finished.  But it was so light I saved it....for 20 years and a cross-country move.  Turns out when your kitty climbs up onto the boom-box stereo to avoid the fleas plaguing the poor beast, the whole stack can become unstable.  And then it (and probably kitty) fall precisely down on top of the model in work.  I finally gave it a better inspection and found that, contrary to my belief, the fuselage structure wasn't completely compromised.  So I removed and repaired the smashed wing and repaired a few joints in the top of the fuselage.  Hope to re-cover the wing later today.  Then on to removing old warps, building a cowl/noseplug and probably wheels.  It won't be pretty, but if it flies as well as I think it might, then I'll build another.

Not sure if this counts as "doing" anything, but... Last week I found where Office Depot will custom print pdfs on demand.  At first, I was only going print the Martinside Buzzard and Spad XIII, but that was 2 $5 prints and $10 shipping.  Since it was free shipping on orders over $25, I did some more shopping.  Once I got there, I saw that orders over $30 got 30% off...  Then, I figured since I was at it, I might as well load up on peanut plans.

That is interesting because our local copy shop (a mile or so away) and quite small takes pdf.s by email and will print them off for collection - A0 size is about £4.00 and I think a Peanut plan which will fit on A3 paper is no more than a pound.  So it is nice to see that lour local shop is not loading the prices - yes OK I know you are in the US but I think I know what I mean?   

This is  not good news in a way because temptation to get lots of plans copied on the pretext I will build them is pretty irresistible.  Because building even half is unlikely!  But then having software like Splitprint etc. and the ability to print them at home easily if you want is not good either.

That is a nice collection of "paper" by the way.

Progressing nicely with Comet Red Racer.  Very large landing gear on this little thing and the a balsa prop (neither made yet) will probably add another 2or so grams. In theory, you could say this plan was scaled to suite the nail gun gas canister supporting the bones in photo 1. I used it form the cowl. Wingspan 12.5”
This will be a another good subject to see how my ezedope/surgical spirit mix work for finishing and controlling shrinkage.

I don't usually come on this thread because most days I don't do anything and if I did I would have forgotten before I have time to write it down. However on this occasion my arthritic fingers jogged my memory about the little baskets that Bernard on his Hummingbird thread used to pick up his magnets. I thought I could do something like that so I got some of my favourite material (old cerial boxes) and my fovourite tool (sharp kitchen scissors) and got to work. After about twenty minutes I took the photograph below. The first thing I made is on the right. I cut a strip of card and creased and bent it to a right angle, cyanoed a stiffener across the corner and put a magnet underneath. Bingo! first time. I could pick up the magnet by just lifting the card, put it down on top of, of beside things and the magnetic pull was not noticeably reduced. The next item along is virtually the same but the corner stiffening is changed to better hold the magnet. The third one along is just a bit of 'doodle' thinking.  I just put a magnet each side of the bottom of a vertical strip. That can move two magnets at once (no great benefit in that ) and holds the strip vertical(no benefit in that either because it is easily pushed over ) but it lead me to try a horizontal strip with four magnets on the bottom which actually does give a firm vertical edge at each end. This is not intended as a solution to anything, just a thought provoker.

For what it is worth I am committed to magnets as they have so many uses.  Wonder how I did without them.  They are a form of universal clamp and the wider your imagination the more you will find a use for them.

Started another project a few days ago, and wanted to post some early progress shots.  I was very happy to locate a state-side source for VMC kits, and I now have the Andrew Darby-designed Cessna 140 and Jodel D-18 kits on hand.  Everything about these kits is outstanding; Mike Stuart's Jodel kit review, and the other builds posted here on HPA, really had me itching to try one...

So here's a bit of Cessna 140 progress.  Will post occasional updates rather than start a new thread.

I was very pleased with how easily and accurately the fuselage went together.  (Yes, we have no bananas...)  Couldn't resist posing this shot.  ;D

Will add the gear and stringers and call it a weekend.

Post by: Art356A on February 28, 2018, 09:25:54 PM
The P-61 is only semi-scale. It's from a Cleveland IT series plan which was evidently derived from photographs of the actual plane rather than factory plans. The big differences between the plan and real scale are much smaller diameter engines (and thus booms) and the pod one station too far back on the wing (resulting in more lead in the nose than if the nose were longer). The changes I made were adding to the center section span so I could use 9 inch props and also increase the stab span. Then the outer wing panels looked too stubby and their span was increased proportionally 'til they looked about right. So now the proportions look okay except for the wing aspect ratio, which only a P-61 scholar might notice. However, it flew two and a half minutes at KOI on 700 winds, whereas experts had told me that a real scale one wouldn't have flown at all. Thanks to Josh Finn's mom for having the presence of mind to click a watch on it.

I had wanted to have a shot at one for a long time, bought the Cleveland plan and slept with it under my pillow for months until I saw pictures from the Montreal crew on SFA of a nice flying one at a Glastonbury Connecticut meet. I wrote Mikey Heinrich to see if he new whose it was and he connected me up with Lynn Morton who told me his was a modified Cleveland IT, and a reliable flier. He gave me a lot of pointers on the mods that he had made and was going to send me his greenhouse molds when he went into the hospital for minor nasal surgery from which he didn't recover. At that point I couldn't not build it. Got very little encouragement from the experts on the Forum, except for Bob Isaaks, who kept me going on the project.

The Lizzie. Out-of-the-box Easy Bilt, 36 inch span. Anything but easily built, but it flies, sorta. Here's a video, right after the Moonbat flitting around...

Art,

Thanks for the backstory on your P-61 - must have been great to watch it max.  I've had the Sterling P-61 kit since the mid-90s but never got farther than building the booms.  One of these days I'm going to finish it, probably as an F-15 recon version.  Every time I pull it out I look at all the plastic parts and end up putting in away again...

Cheers,

Mike

Post by: Art356A on February 28, 2018, 11:44:22 PM
Yeah, I just took another look at the pic. The last bulkhead of the pod is supposed to be even with the trailing edge of the wing with only the bubble aft of it. I only noticed it after they gigged me for not having l.g. doors drawn on under the wings and the pod. I pulled up the 5-views on Airwar.ru and using the leading edge as a datum, found that nothing fit. Then I figured out why. Those drawings also showed the correct cowling diameter. Twin row P&W's never would have fit into this thing...5 cylinder Kinners, maybe.

Today?  I un-taped the Jart I'm working on from the building board...

A Jart is a 60" fast sloper.  Here's a vido of the designer Reed Sherman flying his: https://www.youtube.com/watch?v=MVQhqDtjNrg

I had cut out the opening for the horizontal stab and wing from the composite fuse.  I glued in the horizontal stab, and used a piece of 36" x 11" melamine shelf to jig it up so the horizontal stab was 0-90-0 to the fuse.  I untaped it this morning before I went to work, and from what I can see it's really square. 

After work tonight I mixed up some more laminating resin and cab-o-sil to make a slurry to close out the subtrailing edge of the bagged spyderfoam wing.  I also put a locating pin in the rear of the canopy to keep in aligned when closed.  I still need to make the magnetic latch for the rear.

 West Wings Swallow (https://www.flickr.com/photos/[email protected]/sets/72157692582049641)

First wood cut today, but last weekend was given over to sorting out templates for the ribs 'cos the die cutcrushed sheets are, basically, unusable. Really wish they'd gone for print-wood for them, at least that way the wood wouldn't have been wasted.

It's a shame that West Wings are no longer trading because this is a lovely simple design and promises to be a straight-forward build, but... the kit did come with some traditional KeilKraft Oak of late and unlamented memory.  Check out the difference between the weights of the port & starboard fuselage front sections!

Not really sure where to post this so here will do!  Over the weekend I was at the beach (having taken my VMC Triplane with me as homework).  I was amazed to see a young guy there with a surfboard which had a long high aspect ratio keel with what appeared to be a modern HLG glued to the bottom.  Turns out it was a foiling surfboard.  The main foil has a boom fuselage and tailplane to aid pitch stability.    Down here in NZ we know a thing or 2 about foiling yachts but I have to admit that this was new to me.  Worth googling foiling surfboard for a look if you haven't heard of this before.

;D i am rebuilding my BEAVER as a box fuselage  so the weight will be about 1/2 the original.

jim ;D ;D

Maybe, maybe not. I did the prototypes of both the Porter and Beaver as box fuselage models, intending 700 series not 300 series, and if you want to keep the fuselage corners reasonably scale looking you will still have formers on the top and bottom of the box and the weight saving may not be at much as you think.  It all depends on balsa density and how sparingly you use glue.  Of course you could just ignore the fuselage corners and may it a literal box like Hacker and Dumas did. Built carefully, with the current production wood, the Beaver should weigh about 44-47 grams built out-of-the-box and should fly quite well with the 7" prop supplied. If you do build a box fuselage version use the large stabilizer.  Built with the scale stabilizer it is a bit tricky to trim, and if you have too much dihedral, a degree more than the flying dihedral shown on the kit plans, it will have a noticeable Dutch roll.

I will be interested to see how you do with it.

Just over an hour ago I trotted off down to the local park for some final trim check flights on 2 new 12"WS CLG's. late in the day - overcast with a gentle breeze. It should be safe with over 200m+ downwind. First flight - I launched a tad too steep and the transition was a bit late.
Second flight - better angle, good transition -Ahh - it's not coming down. All the way across the park and I finally woke up and ran after it but was still not close enough when it finally disappeared into one of the trees. After a 40 min search - still couldn't find which tree! Rats! It's ok if they go out of sight vertically - not when you think you know where it is and can't even see it :(
Off into the missing glider dimension or maybe it was grabbed by a passing magpie! :)
This is the second one in 3 Months! I need to come up with a DT for a 8gm 12"Ws CLG.

 ;D  kittyf i built it as a true box using 3/32 wood. my weigt is 50 grams so i save nothing.  not only that the wood did not have much srtrength so handling damage has driven me to tears. win some, lose some.

i also worked on finishing the late jimmy c's stucka. built the tail feathers so we'll see how that goes hopefully the wood will take handling. i did get breaks and joint separations just sanding it.  i don't know how old the model is,.

I'm not sure if it counts as "airplane-wise" but I learned something new about the storage of modelling materials and pain. Specifically, that it's a bad idea to keep your leftover offcuts of thin piano wire standing in the same jar as you keep your small paint brushes. Nothing like a bit of unexpected self-acupuncture to focus the mind; almost as effective as Dan's classic "Xacto knife rolling off bench straight down into foot" scenario.

 (I also learned that the yellow Tamiya masking tape stems blood flow from a wound just as well as Elastoplast.)

I bought a kit for a model aeroplane. The first one since before 6 May 1950. [Technically I suppose I bought a Guillows kit about two years ago when everyone was saying how much better they were.  I opened the box, weighed the sheet wood, put it all back in the box and gave it to a friend.]

CA on  wounds, Vietnam, yes and also packing wounds with sugar, cling film for burns. I was taught this in the Royal Marines nearly 40 years ago and it all came from battle field experiences in Vietnam and I used them all on many occasions. Off topic granted but it brought back some memories!

You must be almost as old as me tctele.  Maggots were quite good for cleaning wounds as well while we are on the subject.  But returning to topic that is a nice picture Mike and that frame work makes it look a bit hefty but apparently it is not.  This is another design that at one time would have sent every one off to build a HWYM! 

So for your next trick can I suggest the Armstrong Whitworth FK10?  I can provide you with a four view and a bit of bumph.

Well using CA for wounds was graphically demonstrated for me while one of the Australian F3B models was being repaired at the 1987 World Champs. Sean Walbank at the time the editor of the White Sheet N/L used more CA on his cuts then on the tail plane he was fixing for us.

Well I spent the day building a Bagatelle, vintage coupe, fuselage. No rush just sticking bits of 1/8" sq together. Then I remembered as I always do building these vintage models that the time it took I could have put together a kevlar/carbon fuselage and built the tail feathers in the same time! Then of course I've got to cover it etc etc.

After I lost my Banana Fritter #2 back in 2016, I started a replacement, but hit one of my building slumps about half way through. In the past week the desire has come back and it's well on its way to being finished. Today I glued on the sub fins and colored them and the rudder with yellow highlighter. In the past week, I covered the fuselage and stab and got some more done on the wing.

My first experience with CA was in 1965 working for IBM as a typewriter/dictation equipment repairman. We had a lot of handheld voice recorders in the field which were built on somewhat flimsy cast magnesium frames, which could crack under rough handling. Frame replacement required hours of work removing parts and reinstalling them in another frame, and that was a non starter.

We would locate the crack, clean everything with Trichlor, dry it thoroughly, and cement it with Eastman 910 surgical adhesive (CA). It almost always worked.

We were told this new product was developed from barnacles, used in heart surgery, and occasionally used experimentally on Professional football players to repair broken limbs by surgically exposing the break and rejoining the fracture with the 910. Supposedly, they could then play again the following weekend. I think that's a tall tale; but I'm pretty sure Eastman 910 was the first successful CA, and it was pricey.

Finished repairing the Tigercat.  Last week I made some bad decisions resulting in the Tigercat plowing into the ground, breaking the wing loose and damaging the fuselage.  I stripped tissue over the damaged areas, repaired the broken formers, reinforced the fuselage at the wing TE, LE, and the former in front of the LE, spliced in replacement stringers where the prop chopped the fuselage, then re-covered all the holes.  A little touchup on the panel lines, re-installed the canopy and re-applied canopy framing and she's ready to fly at Gainesville this weekend (assuming the winds are something below gale-force...).

Stab and fin built.  LEs & TEs  yet to to be sanded to profile.
Ribs cut for wings.
Currently pondering on best way of building what was a more less flat kit wing as a now very slightly undercambered NACA 4412 wing.

Things not to do:
- Don't break any of the supplied 3/32" strip 'cos there's only the bare min. in the kit.
- Inadvertently use the wider strips in the kit when slotting the ribs.
- Forget to cut slots in a couple of the ribs.

Thanks David - winds morning and evening weren't bad but the grass was cut short so the twins stayed in their boxes.  Did get some decent flying in with other models and had lots of good conversation with Mike, Rich, Duke and many others.

Crabby, not sure if i should react to the BS comment. Well actually, it IS deserved...

The grass hasn't had a chance to start growing yet so we faced the usual hard dirt and pungee sticks from the last cutting of the previous year. The grass grows thick stalks that are treacherous when cut. When it does, however, you can slam a plane straight vertical into it and it won't get hurt. Great for trimming those wild airplanes.

Mike did very well and we are all glad that he took two Kanones home for his efforts. I did chance to gaze on his dimer twin Rocket. It looks better in person than in the photos, almost see-thru. But, like he said, the wind was not kind to us. It was actually clam for Texas this time of year. Winds Friday were in the mid 20's.

I did end up pretty busy and naturally forgot to take pictures of any quality. Here's a few that I'm willing to share that shows the conditions. Attendance was sparse mainly due to the forecast for the weekend. First is a shot of the flightline Saturday morning. I could show only half the number of cars. Duke Horn is in the foreground. Morning coffee still hasn't taken effect. We fly with a sister club who fly AMA contests primarily but we co-mingle people to keep the events more active. Second shot is of the twin pusher mass launch event. Great fun here and excellent endurance from all of these models. Third shot is our Flying Horde launch. I didn't bring a plane so I got to take pictures. Would rather fly...

Something has caused Crabby to put his tail up of late - maybe the sap is rising?

Shame about the wind Richard - in the UK we regularly seem to get adverse weather and tend to assume you chaps with the sun get a string of balmy days - but it seems just about everywhere round the world manages to tease us!  And that grass does look hostile.

The pusher event does look fun - I tried to build one of the was a youngster - got a book out of the library of "things for boys to do" which included an "A" frame.  It was pretty huge, possibly five or six feet long and the timber was Ash - and lots of other bits that a young lad could not possibly manufacture but I contented myself with making little bits such as I could.  The crowning bit though was the author then announced that he took a roll of linoleum floor covering on the roof of his car to the field where he flew so he could do "RoGs"  I did not have a car then.

Well it was yesterday rather than today... but what I did was maiden my Middle Phase slope soarer which I've just finishing building from the Chris Foss kit with aileron wings.

A bit of a change from stick and tissue, and took considerably longer than I expected, but I was on a learning curve doing lots of things for the first time - foam-cored wings, 1/4" balsa, iron-on film, aeroply and the suchlike.

The colour-scheme is a bit shocking, but it jolly well works!  And the maiden session of three flights was a complete thrill!

I agree on all counts.  Where was that - on the Ridgeway?  Very nice pictures Jon. Norfolk does not really have any hills to get in the way of rather scenery so a bit limited locally - some chaps fly off the cliffs as do the microlite people.   I have a Sonata somewhere - may get it up and running - they're good on a slope and do not need a load of puff.  At the moment I am a bit immersed in the little FF scale stuff.

A very nice aeroplane indeed, but really; is that any sort of hat for a gentleman to wear whilst flying?  Tsk, tsk. ;)

In other news.  Lurker Industries have received a series of stiffly worded memoranda from both the Ministry of Supply and The Board of Trade expressing their joint displeasure at the low rates of production currently being achieved. The Board of Directors have replied most forcefully that unless the shop floor staff and skilled tradesmen are permitted to continue taking tea breaks at 11 o'clock in the morning and again at quarter past 3 o'clock in the afternoon all production would cease entirely.  Which is why it has taken a good seven days to produce a single wing.  Of course if the drawing office hadn't mucked up the rib plans it would have taken only 5 days.  :)

Russ - I do find slope soaring to be an almost meditative thing to do, being in the natural elements of landscape and wind, a bit like sailing.  The Middle Phase is my first 'proper' RC build and I love the weight and penetration of it - versus the lightweight ARTF foamie I first learnt on, useful at the time but horrid to hold and behold.

David - you're spot on, it is Uffington White Horse Hill on the Ridgeway.  The bowl faces NW and on Saturday the wind was in exactly the right place, 16mph gusting up to about 23.  Video here: https://photos.app.goo.gl/iQsZY7SIqZyVvDus2 (https://photos.app.goo.gl/iQsZY7SIqZyVvDus2)

Ah.  It's a "scrit" build.  Officially it's supposed to be a kit (die crushed ribs & some 1/8" router cut sides & formers) but it's turned into a scratch build.  The die-cut ribs weren't usable, some of the supplied sheet was made of corrugated tin and quite a few lengths of the supplied strip wood have been replaced with my own strip; especially for the stab. & fin.  I think the part count of kit bits is now well under 10.  

FWIW the replacement rib profiles are from my noddy SVG aerofoil plotting util *waves hand in general direction of plan gallery* and more or less NACA 4412 but instead of taking the spar slot positions from the plan for the first set I took them from the kit die-cut sheets.  Twit eh?  :)  I wasn't too upset as some of the slots I'd cut in the 1st set were not as square as they should have been so it gave me a good reason to redo them.

That all sounds like a tale of woe, but it's been fun rescuing (trying to rescue - hasn't flown yet) what is a rather nicely designed model.

Ahhh, that would have been a bodge too far even for me and even when the wing is covered I would know it was bodged and it would have niggled and niggled at me. :)  

There were a couple of other reasons.  A good number of the other slots weren't cut acceptably square/tight enough which would have lead to weak joints - see example in the attachment - and I wanted to use the kit supplied root and tip rib. These are the only usable ribs in the kit.  They're router cut from 1/8" and slotted to match the plan. Moving the spar would have given an awful buckle at each end of the wing.

Got the Banana Fritter covered other than the nose block. Still need to glue on some alignment bits for the wing and stab. Noseblock is glued up and ready to shape. My attempt at a stylish nose decoration flopped, but it's not so bad that I'll redo do it. You can't see it in flight anyway. :P

"AIR CAMPER"  DUMAS KIT #231"   FREE FLIGHT

     I worked on my 18" Dumas "AIR CAMPER" today.  I glued up the nose former and stringer that was cracked,  and I cut the old ripped tissue out of the front top of the nose.   I will infill plank these four slots on top of the nose, for a stronger nose.   Also, the nose block was getting too loose, so I started gluing in, and sanding, some small balsa slices to get that really snug fit, that prevents the noseblock from popping out every time it lands.  This little "Gypsy" has been so good to me, and is without a doubt, my very best and most dependable flyer (my record  62 sec  flight).   Many crashes and repairs and she still flies like a Champ.  Now that I know how to braid a rubber motor, I think I will experiment, to try to get a new endurance record.  I am also going to recover the rear half of the fuse with new tissue.  It is chock full of transparent Scotch Tape !!    :-\    -  from all those crashes !!     :-[   -  and quick field repairs ...   :)

"AIR CAMPER"  18 "  DUMAS KIT #231    FREE FLIGHT  RUBBER

Well, I worked some more on the Air Camper this AM. 

PIC #1    8557
This last extra sliver of balsa, for the nose block, has dried over night.

PIC #2     8558
The nose block is removed from the pins and blocks.

PIC #3     8559
Now the extra sliver on the noseblock is sanded even down to the block edge, and now the inside face has been filed with a Jeweller's file, and the Tenon is also shaped, for a snug fit into the cowl Mortise hole.  Way tighter than it was before.

PIC #5     8561
The four new infill  planks, for the top of the nose, have been cut out and sanded, and fit just right into their slot holes, and are ready for double white gluing.

"AIR CAMPER" REPAIR  18 "  DUMAS KIT #231   FREE FLIGHT  RUBBER

     Well, I got some more work done on the Aircamper, to get her ready for the rest of the season.   PIC #     8573
     The four infill planks on the top of the nose are now glued up and dry, but not sanded down even yet.  I coated the nose block face and "Tenon", and the front former face and "Mortise" hole, with some lightly brushed on, super thin CA glue.  
     Then I decided to strip off all of the fuselage tissue covering.  I really hadn't realized how much Scotch tape was covering almost the whole fuse, or how many uprights and longerons and crossmembers were really broken.  Clear Scotch Tape really helps for immediate field repairs!
PIC #     8562  
     This shows a lot of missing balsa pieces in the fuse, after I cut and sanded the old tissue covering off.   So I started little by little, gluing in a couple of small balsa pieces one at a time, and letting them dry overnight.
PIC #     8571  
     This shows it coming along slowly, with a few pieces glued in so far.  Also note the small piece sitting under the fuse that I had to glue up first also.  This work is hard because I am working in thin air, mostly, to glue on these pieces.
PICS   # 8569   &    # 8570  
     We had a freezing rain storm over night.  View of Jackson Park across the road, from my icicle spike, "stalactite" laden, apartment balcony, top and bottom, horizontal railings.

Lurker Industries' Aero Division is reviewing it's preference for NMF aeroplanes following very strong representations regarding materials costs made by the Chief Accountant to the Head of Production.  In other company news the company's doctor says that the Head of Production's scars will heal, in time, but he'll probably always walk with a limp and the Chief Accountant's bruises will fade fairly quickly but the remedial dental work will be quite involved.

Or....

Placed a bulk order, well 6 sheets, for Ag / Al tissue with VMC.  Failed to get a decent result on first go at the Swallow's wing; have a dekko at the attachments for an object lesson in how not to cover a wing.  Wee bit narked about it, but it is (ha ha) a recoverable situation.  I will get to grips with working with Ag / Al tissue if it bankrupts me, which doubtless it will.

I sat down today and looked properly at my Peck Andreasson Peanut to try to fathom why I'd made such a pig's ear of flying it at the weekend Nats.

Being under the weather at the time (while also dealing with the anxiety of not crashing and further damaging my CO2 Camel, as I'd done during trimming the day before), I simply failed to pay attention to the basics!  In fact three of the Andreasson's four wings had warped un-noticed over the last few months.... so two surfaces which were supposed to be flat or with wash-out had acquired some wash-in, while one on the other side that was supposed to be flat had wash-out... and all the while a random up-tab on the wash-in side was playing the joker!  :o

That'll learn me  :'(  but I did manage this morning to steam everything back to how its supposed to be.  Now only got another 51.5 weeks to wait until its next chance!

Oh, and I had my first exploding rubber on the final round, with consequent damage to the tissue in three places, which is my prompt to finally make a blasted blast-tube!  :-[

Did some more thinking and flew some computer sims. Decided on the Guillow's Aeronca Champion "85" as is similar to an addon for FSX that I enjoy computer simming.

https://www.avsim.com/pages/0708/RealAir/Champion.htm

On the computer I enjoy the Tundra, and the float or amphib versions the most. Plenty of shaggy grass and ponds around here.
Kit is on hand and already had a spare print made.
Plenty of easy viewing paints schemes on the sim.
Longer flight times are probable.

 Decision Made.

     Well, everything is glued up, dried, and sanded to 220 grit.  The revamped nose button is nice and tight. And all of the gussets have been sanded to a concave round shape with a round file.  It looks like it could fly, just like it is, with an open framework fuselage.  I sort of like the way it looks right now   :o  - like those early aircraft. Here is a few pics before I put the new tissue on tomorrow.  The tissue will be glued to every upright, crossmember, and longeron, and stringer - it will be my "fully stressed skin" fuselage.   8)  Plus I have to acrylic paint the top of the nose, infill  planking, the color of "pure pumpkin orange".  At least now I have a sturdy fuselage for this season, which starts on Friday April 20 and goes for five straight days, max wind mph each day is 9, 5, 7, 9, 6 mph and sunny each day, the forecast high temp in deg F each day is 48, 52, 55, 59, 59 deg F.   The grass should be growing longer in the Cricket Wicket   ;D  , and I do not think they will mow it yet.  Oh, and I need to make a couple of "braided motors" to experiment with ...   :)

You've been busy in the factory Richard. Maybe Lurker industries could employ you :D
You've done a nice job of removing the tissue on such a small model. If you use white glue to attach the tissue(?) - how did you remove it without damaging the structure?

Title: Re: What Did You Do Airplane Wise Today?
Post by: LASTWOODSMAN on April 20, 2018, 07:34:45 AM
     Good morning John - yes I always use white glue to attach tissue.  I just lay a small bead over the balsa,  of a thinned composition of  70% glue mixed with  30%  water, and it sucks the tissue right down as it dries.  I flatten out any small wrinkles as it is drying, by using a wetted piece of balsa, and press or burnish those wrinkles flat, and you can get a perfect result.
     Yeah John, I don't think there is an easy way to remove tissue.  I take a long time to do it.  I cut out what I can, and then I sand off the rest using a lot of different files and fresh sandpaper stapled ( I never glue anymore ) onto balsa sicks.  And if some glued tissue is persistent in not coming off, I wet the tissue with a small brush and water, and use an Exacto knife and some small wood carving tools to scrape it off.
     Oh, yes, I do damage the structure and break things, but then I put on a fresh piece of sandpaper and go back to lighter sanding strokes ...  ;D  takes longer but ...   ;)

I take my tissue off in my wife’s hot tub. Even the doped on stuff. You will never try this but if you do, have a dying jig set up so you can keep things straight in the drying process!

     This is the second last tissue panel for the fuse, then it is all done, ready to trim off any excess tissue, glue down any edges, and shrink it all with atomized water.   I had to block up the plane well, in order to get a good placement of the tissue.  You can also see the large balsa blocks I use for resting my hands on, while laying down that bead of thinned white glue, with a small paint brush, and a good support for laying on the tissue.
     Then to put the prop and motor in and go flying, this afternoon!    ;D

Post by: tom arnold on April 20, 2018, 09:50:52 PM
I attach my tissue with thinned white glue and a small brush too. When I want to remove the tissue, I puncture each bay of tissue such that water can get inside the model and then submerge it in the tub. I let it sit underwater for a day and the tissue just  falls off. A shot of dishwashing liquid  helps accelerate the process and I usually have to put some kind of weight on it to keep it  under. I have found, while the structure is a bit delicate while wet, it dries as hard as it originally was and it does not warp. Yes...... does not warp on its own, however, it will take whatever shape it dries in so I either pin things or carefully place the model in a position in which all is straight and lined up and do not touch it until it is completely dry. If something (like a wing) does dry with a warp in it, I dunk the wing into some water again and pin it flat to dry. If you assemble the framework with water-soluble glue like Elmers, this will create a disaster and dissolve everything as you can imagine. It is really pretty easy.

If you wind up picking off the tissue while leaning over the tub, be sure to NOT let the scraps go down the drain. Our Esaki tissue gets stronger when when wet and does not dissolve like toilet paper. It cost me an $80 plumber's bill to learn that.

     I walked the dog at 3:00 PM and the Cricket Wicket was full of Cricket players (first time this season).  And the wind actually picked up to  12 mph  gusting to 19 mph  - too windy for the little 18 inch Aircamper.  Tomorrow is another day with forecast 4 mph wind, gusting to 6 mph, all day, so I might as well wait til tomorrow.  "Discretion is the  better part of valor."  
     If the cricket wicket is full again tomorrow ( which it will be )    :'(   , I can always try and sneak in to "Windsor Stadium" (where they play football and soccer ), also part of the Jackson Park complex, and right beside the Cricket Wicket.  It is always locked up, but I know where the secret hole is, in the fence, right beside the high school, that the kids cut open ...    :o

PIC #     8612
     Here is the last tissue panel.  It had to be the exact triangular size to overlap a  1/16"  stringers on each side.   So I cut out a paper pattern and trimmed it to fit on top of the fuse, and then I scotch taped it onto some tissue.   Then I cut the paper pattern out, leaving the exact shape of tissue to cover the top of the aft fuselage.  

PIC #      8615    
     Here the plane is all blocked up again securely, in order to glue on one little tissue panel !!    ::)     The triangular tissue panel has two centering pencil dashed in the middle of the front and the middle of the back of the panel.

PIC #      8616
     I installed a temporary little plank at the front of the tissue placement to help locating the tissue.   The tissue panel has two little centerline pencil marks on it.

PIC #    8616 SNIP
This plank has a centerline marked on it, in order to help line up and center the tissue panel's two center pencil dashes, because when I put on the tissue, I will not be able to see the center top keel, at the front under the tissue.  I also filed out a couple of "clearance" holes in this plank, so that the tissue does not glue to it.

PIC #   8617
    Here is the last panel all glued up in position.  It worked out OK.  I will try to get some nice outside pics of  this Aircamper  tomorrow before I launch it skyward ...   :)

PIC #   8618  One pic of the final result.

Nice repair work, Lastwoodsman, but a morning of DELIBERATE DESTRUCTION for me! I'm having a good sort out and tidy of my workroom and need to clear some space ready for building my Dumas 30" Eindecker. So...a couple of my bigger, and now very tatty models, which could no longer justify their shelf space,  just had to go! I can very rarely bear to do this, but it felt quite cathartic.

Goodbye then, Bristol M1c and Morane Parasol; now broken up and in a bin bag (although I saved the pilots and wheels).
A couple of farewell photos of them, as they looked in better days...  :D (pics by Russ Lister and Laurence Marks respectively- thanks!)

MKelly, That 262 looks incredible. Sorry for the late posting. Can't wait to see it in person.

Lastwoodsman, I feel your pain on repairs and retissue. It's always a pain. I'm in the process of repairing several models which require taking off old tissue, replacing it and trying to color match decals and such. It's never right but adds to the character of the model.

Rich I couldn't agree more with that statement. You never saw a picture that describes this better than the locker room photo of the Montreal Canadiens after winning game seven of the Stanley Cup. What a bunch of stitched up bruised up banged up bandaged up warriors! They had their character beaten in!

Pete, you are giving me the courage to euthanize a pile of pretty but over-worked models. Some of 'em not even mine! Do you recommend putting them in a bag before performing the stomp, or wearing a blindfold? Of course some dance music and a few pints might work best of all!

I think it should be quick, but the exact manner of execution is a matter of personal preference. The important thing is that they get crunched good and proper, so that once in the bin bag there is no temptation to get them out again for a soft hearted reprieve!  ;D

Yes Pete - "Crunched good and Proper"  LOL   Anyone burn them any more? or use them for trap and skeet shooting practice ( which would be good for the final flight ) ?

AIRCAMPER  18"  TEST FLIGHTS

     I tested out the "new" Aircamper this morning.   About a dozen flights with just finger winds up to 110 winds on that  6"  braided motor.  Test glides were good, but under power, max flights only  6  seconds, it just powered and climbed up and up, stalled, and came down.   :P :-\   Adding weight to the rear wire skid, did not help, and neither bending the stab tabs downward either.  Some flights were climbing and stalling and climbing and stalling.  It seems that the greater power burst from that thick braided motor  6"  four strands of  1/8"  is too much power. ( ??? )  I came back and will put on a  9"  two strands ( one loop ) of  3/16"  ( unbraided ) motor, and bring the stooge and a supply of motors with me, when I go out again today, and give it another try.  Here are some pathetic pics of the plane all over the place ...

AIR CAMPER AFTERNOON FLIGHT APR 21 2008

Well I did go back out this afternoon.  The longest flight was 25 seconds, of about 11 flights.  Had to fly in Windsor Stadium as the Cricket Wicket was now full of players.  Two bad crashes and no damage - thank goodness.  The wind was really swirling and wreaking havoc, coming from behind the big concrete grandstands.  Full flight report is in "Your Birds in Flight" here  http://www.hippocketaeronautics.com/hpa_forum/index.php?topic=23194.msg224130#new

Hi Richard, you might also want to try a smaller prop with a flatter pitch. I have the Peck Air Camper. I will dig it out and see what I have on it. Not that its gonna be the way to go, but it is a really boring stable flier. No nutty hi-jinx. Just nice boring flat circles with a gentle climb.

I've started my enlarged Banana Fritter. I've enlarged it to 36" span by blowing the plan up to 120%. I'm planning on making my first folding prop for this one. I've got the rib patterns and most of the sheet parts glued to the balsa ready to be cut out. Plans are attached to the building boards.

I gazed at my flying field despondently.

After a long, long winter that only ended a week or so back, and during which I often thought, "long grass. . .long grass. . ." this is not what I wanted to see. I didn't realise how lucky I was in previous years when the farmer would grow two silage crops in a year, meaning two episodes of long grass and no cows until July or August. Last year there was just one crop - now none.

The Martin-Baker MB5 and Westland Whirlwind I've been working on here and there through the year will be shelved in favour of something that will fly onto short grass from the outset, and will need less space than the rangy Whirlwind. That's what I'm thinkin'.

18"  AIR CAMPER FLIGHT APR 26 2018

     Well I got the little "Gypsy" out again -  10:45 AM  48 deg F, winds  4 mph from West gusting to  7 mph,  54 %  humidity.    ;D    I found out that every time you change to a different length (weight) motor, you have to add or take off clay weight, so that it does not "porpoise".    ???    Finally got her trimmed with a   3/16"  motor, two strands each strand 12"  long, prop hook to rear peg is  7",  about  600 winds and my best flights were a couple of 35 second and one 40 sec flight.  The noseblock was still wiggly from side to side, even though I painted on some thin CA last night.  So I cut a couple of thin strips of clear Scotch tape,  and taped the noseblock to the fuse to hold the proper side thrust, one strip each side, and making sure the tape strip started on the black thrust button,  to hold it in place also.  It REALLY worked !    About 15 flights until it flew into, and got really stuck in, a tree.     :(    I had to go climbing and shaking different branches, but she finally came down - minor tissue hole damage.  Then we went home.  I am too old to climb ...   :o
     My six best pics.   I am now thinking about getting the  30"  Rearwin Speedster out later ...   8)  these windless days do not come very often ...
KEEP 'EM FLYING !!

We got us a no wind day here in N TX.
Grabbed the Guardian, Rumpler and a newly converted to E power SE-5.
The SE 5 was an old 5 yrs ago built rubber ship. I installed a couple of balsa
formers to support the 5/16 x 3/16 stick that the GWS geared motor
stabs onto. Made up a quick harness with a switch, charging stud, battery and
motor leads and bench checked. That was about a week ago.
Today is perfect to try er out. One thing I like about ni cads is that you can
control motor run time by charging time. 15 sec time resulted in a stretched out flight
without any climb. OK stick some clay on the tail skid and gave er about 30 sec.
Away she went, 2 nice circles to the left about 20' up. Success.
Rumpler time, Cranked in some turns and tossed er. Flew OK but had a stall at the end
of the motor run. Looks like nose weight is needed and remove the stab downwash tab.
Next toss revealed a straight away flight with little climb. Humm lets remove some
of the 6 deg of downthrust. Took out 2 deg and tossed er again. Good looking
flight pattern occurs. Put er away for now.
OK moving on to the Guardian
Removed a large amt of washout from the R wing the other day that showed up
during the previous trim attempts. Using a 4 (1/8) loop motor with the 4 blade prop
model climbed out with a stall tendency but recovered OK. No biggie.
Slapped on more down thrust and cranked in some turns. Well she liked this.
On about 60% turns she started grabbing sky in wide RH circles, 4 or 5 and
she settled into a, no drama, nice glide. This one will be lost before
the year is gone.
So a new record for me, 3 models, mostly trimmed out
within 3 hrs. The Gods were smiling. What price will I hafta pay down the road
for this great day.

Richard - that little model is earning it's keep. I think I would be considering a blast tube - even if it was only rolled up from cartridge paper or thin plastic.

 Well, Mike - you had a great day too.  Me too, my first time successfully flying two models - yeah ...  and what price to pay ?  - I think I heard the "Laughter of the Thirsting Gods" of Free Flight whistling through the trees when I was out there having such a good time ...  LOL   ::)   ::)
     Well, I did give it the 'ol College effort, and I went back flying this afternoon, after flying the  18"  AIR CAMPER (Reply #415) in the morning,  this time with the  'Jumbo'   30"   REARWIN SPEEDSTER.   At  3:45  PM, it was 55 deg F, winds were 12 mph from the SW gusting to 19 mph, and only  58% humidity, and NO Cricket players on the Wicket !!   I used a thick wide elastic to temporarily Jerry-rigg the left side wheel and wheel pant onto the  1/32" landing gear wire.
     This Speedster has a tight, braided, heavy duty  3/16" rubber motor of just under   15 1/2"   in length - prop hook to rear peg is  15 1/2".   Launching downwind in the leeward side of the trees, I needed that real  burst of power to get it going faster than the 12 mph wind, when it finally gets out of the lower speed of the sheltered wind, and out into the real wind, in order to get enough lift.   It did great tight circles back into the windless leeward side of the trees, so I had some great flights - about a dozen - longest flight 24 seconds.  Here are the best 6 pics.  I will post flight reports, and all the pics, in "Your Birds in Flight" later, for the Air Camper and Speedster ...

Finally got an acceptable finish to the Swallow's wing.  Only took 21/2 goes.  Shrunk but not yet "doped". Stab and fin drying off.  Fingers crossed for a flyable 'plane by Friday next.

Note for UK builders using Eze-Dope (And I still think that's a damned silly name).  Boots sell small pump sprays in 50ml and 100ml sizes for under 2 quid in their travel section.  They give a better spray than any other I've yet found; it's finer and as a result don't get so much white speckle on the 5% coat as other pumps I've used to date.  You might be able to see the difference on the upper wing in the attachment.

RUBBER MOTOR INSTALLATION  page 1  of 3

     Today I took on that daunting task of changing the crumbling  6 year  old rubber motors of my two 6 year old Guillow 16" Spitfire and Stuka die crushed models.   Even the water slide decals are crumbling off.   In order to clear up some shelf space, and before just giving them away to some little kids, I knew I had to put in some fresh rubber, so the kids at least had a prop to wind and spin.  The fuse opening from the front and going back to the rear rubber motor peg dowel was so tight, I had to sand down the tip of my smallest Rubber Motor Pushing Tool.  Even the kit supplied, prop wire's rubber motor hook, was too large to even pull out through the plastic nose cowling hole, so I had to squeeze that prop hook a little tighter with pliers to easily fit through.  This whole operation was quite the ordeal !!
     I tied up a couple of  3/32"  rubber motors, making sure the length was shorter than the prop hook to rear peg distance, thereby having the rubber motor under enough stretch tension to pull the thrust bearing in tight to the plastic cowl.  

PIC #1   8763      and       PIC #2   8762      I also had to cut out small sections of tissue at the bottom of the rear fuse where the rear peg mount was, in order to even see what I was doing.

PIC #3     8746    I made a wood dowel for the rear motor peg, and chamfered a deep radius on the ends,  and I tied up a  3/32"  rubber motor to the correct length,  and I tied a length of twine string to the front of the rubber motor ( the rear of the rubber motor is the knotted end ), in order to stretch and pull out, the front of the motor, out of the fuse, once I got the rear end of the rubber motor around that rear dowel motor peg.  

PIC #4     8748     Here you can see the string is tied to the rubber motor.

RUBBER MOTOR INSTALLATION   (cont)   page 2 of 3

PIC #1     8749     Here are three different sizes of Rubber Motor Pushing Tools that I use.  The rear knotted end of the rubber motor is slid over the Pushing Stick, then stretched out a little bit by the string, and the string is then masking taped to the Pushing Stick,  keeping the rubber taught and tight into the tip of the Pushing stick.

PIC #2     8750     The Rubber Motor Pushing Stick is then inserted into  the fuse all the way back to the rear motor peg dowel hole.  In order to line up the hole with the tip of the Motor Stick, I cut out a small section of tissue at the bottom of the fuse rear where the rear peg mount was, in order to even see what I was doing.
     Here the dowel has then been inserted through one side of the fuse, through the rubber opening and tip opening of the Pushing Stick, and out through the other side of the fuse.

PIC #3     8751     Now the masking tape that holds the string to the Pushing stick, that masking tape is removed.

PIC #4     8753      Now the  Pushing stick is pulled out of the fuse, and the rubber motor end stays put around the rear motor peg dowel.

RUBBER MOTOR INSTALLATION  (cont)  page 3 of 3

PIC #1     8754     Now you can pull on the string to stretch out the front of the rubber motor, past the front of the fuse.  And now you slip the prop wire's rubber motor hook onto the rubber motor while the string is still tied to the rubber motor.   That prop wire also has the black thrust bearing, red propeller and white plastic nose cone, all attached to it.

PIC #2     8755     Now the string is cut off from the rubber motor, while you hold the rubber from snapping back into the fuse.

PIC #3     8756     Now, you can nestle the prop, spinner,  and the black thrust button into the hole of the plastic cowl.      

PIC #4     8757      The prop on the Spitfire spins now after winding !!   WOO HOO

PIC #5     8761      And the Stuka's prop spins too.   YAY  HAY

PIC #6     8766      See-through Stuka prop spinning with nose cone.

Now I don't feel guilty about just giving the models away with the props not working ...    ;D   :o   :D   8)

We had a spectacular day for flying today. Ironmike and I took two carloads of models and spent the day trim flying. Weather in the low 80's and no wind, 1 - 4mph!! Flew my Midkiff FW190 with great success. Two loops of 3/16 - 27 inches long driving a three bladed Peck prop. Note the climb at launch. Couldn't ask for a better day.

FW-190 looks great Rich!  Had some nice weather this morning in San Antonio as well. I worked on trimming the Skyrocket and Tigercat, still lots of work to do on both but I know more than I did yesterday...and I don't have repairs to do tonight!  Also flew the Navion and Me-262 jetcat, some nice flights from both of them.

Unenviable records.  No 1 in what ones hopes will be a very short series.  From build complete to needing repair in under quarter of an hour.  Sickening crack from the fuselage as I'm tinkering with the positioning of the wing, fuselage cradled on/between my legs - too firmly as it turned out.  Rearmost former has given way on underside, tear in topside tissue.  Fortunately all easily repairable.

Anyway the good news is that the Swallow, having been formally named by MrsLurker, is now ready for trimming. However as the met. wallahs are issuing nothing but dismal reports for the foreseeable future there's no tearing hurry for that.

     We just got back after heading out to the tall unmowed grass   :o   around the Spitfire and Hurricane replica warplanes in Jackson Park, to do a little glide testing with the   17 1/2"   Fokker EIII EINDECKER, right at twilight gloaming, with that big yellow full moon on the rise above the trees, shining down on us in the fading light.  A couple of test glides, and I had to add clay to the nose.  Then I started off with 50 finger winds - only a very soft slight breeze blowing.  Went up in increments of 10 winds, had to put a little more clay on the nose and worked my way up to 200 finger winds for one complete right hand tight circle flight of  6  seconds.   I will tuck all of that clay deep into the top of the inside of the cowling, and tomorrow (weather permitting - or not ? ) it is time to put some serious winds into that motor with the winding stooge, and see what it will do.  I will also put a little tab of file folder cardboard onto the rudder for a little more left turn to counter the big right hand turn.  No more languishing lonely   :'(   on the shelf - over four years -  for this little plane ...  All up weight (AUW)  is    34.40    grams,   and the clay I added is    2.10    grams for a total of  36.50    grams.   And with   44 .25" sq of wings, it gives me a very heavy wing loading of   0.82 grams per square inch of wing area !!!???  :-X  :-\

Yes. The calamity was entirely self-inflicted and I will do my porridge as I should, but in mitigation yer honour I would like point out that finding elastic bands in a decent range of sizes these days seems to be a harder task than it ought to be and sometimes patience is in desperately short supply too. Thus the tale has a suitably moral ending. :)

I have a special word I keep in a box...
Yes. Me too. This time it was uttered with a despairing tone. Just as well MrsLurker was elsewhere at the time. She would not have approved at all.

As to the finish. Fairly pleased with it.  I need to work out a better way of using Eze-Dope with Al. tissue. The misted on shrink 5% sol'n is OK leaving aside a bit of white speckle, but the brushed on 30% coat even when done extremely carefully tends to lift the colour leading to a slightly oxidised look in patches.  If get the time this evening I'll try and post a couple of macro shots to show the problem. I can live with it for now but I'm considering try to mist on the 30% coat next go around with Al. to see if that gives a better result.

BTW. Do we have a "kit review" thread anywhere?  I know the kit is no longer in production but I may have a couple of useful notes for others who have got the kit in their hoard / build backlog but they don't justify a full build report.

You might consider crossing the rubber bands diagonally - safer that way - or use four (lighter-section) bands, first pair parallel as per your picture, second pair diagonally.

Tow-hook in place?

Crossed bands give more drag and the wing won't ping off in a crash. Seen many broken wings still attached by crossed bands

I will also put a little tab of file folder cardboard onto the rudder for a little more left turn to counter the big right hand turn.

Check carefully for warps Richard if it has a more than a very gentle turn to the right. If none I would still trying adding more turns in small steps. If the right turn increases with speed then either there is too much right thrust or there is a warp inducing roll and opposing the torque. If the turn to the right opens up as you add more power and you have a glide turn to the right then you could add a tiny bit of right side thrust.

Rudder is very powerful at the higher speeds of powered flight and should only I feel, be enough to give a decent glide turn. I wouldn't be too keen to use rudder too much under power. If it will fly right - right then that should give you more height and longer fights.

Anyway just my feelings on the matter.

Good am. Yesterday was a great day to fly in Palm Bay, so I took my naughty Mig-15 out for an attitude adjustment. One flight she tears up to Zeus and hangs up there for 2-3 minutes, the very next flight she corks into Hades, next flight its worse, puttering about in Limbo. Never doing the same thing twice. After doing everything image-able, I reluctantly gave her the thing she needed... right thrust! After 3 two minute flights in a row I decided she not flukeing and was back on agreeable terms! Then the phone rang: "Late for the opera!" I had to race home and then sit through arpeggios, addagios, soft piccolo, and the likes in my sweaty flying duds! Here she is behaving poorly https://www.youtube.com/watch?v=NM0yHFzl6lM You may say "Crabby WTH is wrong with that?" well when you've seen the "A" student, the "C" student just needs a good kick in the "A"!

 We just got back after heading out to the tall unmowed grass
We demand pictures of this mythical tall unmown grass! :)
That eindecker is lovely.

Right, as promised earlier today a picture of the "oxidation" effect I get when brushing 30% Eze-Dope onto Al. tissue.  I assume (klaxon: wild speculation follows) the colour is slightly water soluble and there's enough drag from the bristles to pull it off the backing tissue. 

Continuing the subject of not quite working you may not want to bother trying to print on to Al. tissue with Canon's inkjet inks. The yield of usable printed labels/decoration is distressingly low per A4 sheet. Three usable labels out of 8 and one of those was borderline usable as far as smudging/ink run went.

Cheap man's Go-Pro - a $30 keychain camera duct-taped to an old ball cap.  Camera is this one:

https://www.amazon.com/gp/product/B06XY61WK3/ref=oh_aui_detailpage_o06_s01?ie=UTF8&psc=1 (https://www.amazon.com/gp/product/B06XY61WK3/ref=oh_aui_detailpage_o06_s01?ie=UTF8&psc=1)

When you're looking online for the camera be aware that they sell two versions, one with a 70 deg field of view and another with an add-on lense giving a 120-deg field of view.  I tried both and found that the 120 deg camera made it more likely you'd keep the model in the picture, but rendered the model a dot making it difficult to see how it was flying.  I like to review the flights to assess how my trimming is working, so I put the 120 deg camera away and only use the 70 deg version.

Picture quality isn't great compared to my iPhone but the convenience factor wins out, especially with two-handed operations like jetcat and rubber twin launches.  Video output is 1080p, but I suspect the sensor is only DVD resolution.  You've got to supply your own micro SD card.  File sizes are kinda huge, about 25 gigs for an hour of video, but it interfaces like a USB thumb drive and the video can be played and edited by pretty much any video program.  I use Movie Maker (again, because it was free and I'm cheap).  Those video editing programs will also allow you to save the video down to much smaller file sizes.

Cheers,

Mike

FOKKER EINDECKER
  
     Well, I did get out trying th fly the  17 1/2"  Fokker EINDECKER this AM after running the dog.  Had an 11:45 morning appointment so I rushed out to the Cricket Wicket, and had a dismal trimming session - nothing worked - only upon changing to a larger motor with another resulting poor flight, did I notice that I had forgotten the  2.1 gram clay noseweight on the building board.   :-[   ???   ::)
       So ....   after my appointment, I hurried back out there trying once again to fly, with everything in place,  the winds were a little on the strong side, making progress (?) with trim tabs and weight on the wingtip and downthrust shim, and different motors, etc. , and getting a ten second flight, it finally, on the last flight,  CARTWHEELED, and broke the fuselage right in half, right behind the TE of the wing, right where there was a missing bottom crossmember of the square fuse box frame ( I built this 4 years ago when just starting back into the hobby - I must have missed it ).    I CAN fix it, but for now - back to the drawing board .   The only good thing I did today was give away my old  16"  Guillow Spitfire ( with new rubber ) to the first little kid I saw, a little 5 year old boy, from our apt bldg.

Hi John - camera controls are straightforward and I've had no issues getting files off the camera or viewing/editing them.  The only hassle has been remembering to tilt the cap back a bit on my bulbous head to keep the model in the field of view.  I picked up some Velcro and am going to make a small foam wedge mount to solve that problem.

Good am Richard, I admire your guts to go fly your Eindecker! It is a pretty model even in its busted up glory! Looks like a dead Mockingbird laying there. I have stayed away from that one because it would only break my heart. BUT I have as most modelers do, a triage unit. All my models fly eventually ::) and they are a bunch of stitched up battling broads who hate my guts as a pilot. But I clean 'em up, apply fresh make-up, and roll out to the "Tall Grass" ??? again. The kind thing to do would be to burn and move on, but I am a perennial grape-squeezer, going for that last drop! a model torturer from Guantanamo for sure! Fix that model and do it again is my advice. I have seen those things fly well. Oh and if giving that Spit to a 5 year old was the only good thing you think you did that day I am sure you are a little myopic! ::) ;D

     Thank you for your enduring, relentless, noble, and gallant efforts, at preserving the English language, most deserving of a Knighthood of sorts.   Always fun to read your compositions.    :D   You must have been an English Professor or like academic.    :)
     Yes Crabby, I think I will endeavor to repair the Eindecker later, as the "guillotine" fuselage break is actually pretty clean.  I am infatuated with actually flying at present.

Your Mig flights seem moderately acceptable Crabby so I am sure you will shortly succeed in reaching the A Grade! (By my standards that one would be A plus by the way.  Presumably the opera was Die Fledermaus?  Or Flying Dutchman).

Richard, I agree about Crabbys talent for the abuse of the English Language.  It took me a little while as a dumb limey to follow the tenor, but this is I am sure due to my servitude in the legal profession!  Once mastered I can now fully appreciate the colour and simplicity but superbly descriptive quality of the phraseology. 

“Stitched up battling broads” is a phrase I will remember - so wonderfully politically incorrect, chauvinistic and descriptive. It reminds me so much of a somewhat domineering aunt of vast proportions from my childhood, who in her flowing dresses my father likened to a galleon in full sail.

The picture of your Eindecker is very sad.  It really is a very appealing model. 

Aeromodelling wise today I have stuck together some bits of timber to fashion the nose block/cowling for the Lone Eagle.

Galleon in full sail, now that is hilarious! The mental image goes along well with it.

So, I've been in the throes of fixing/restoring an older electric power SE5 that served me well in FAC competition. A LiPo battery runs an old tech brushed motor through a Smoothie timer. Took me a day to figure out how to program that [email protected]^& thing but I did it. I had to repair some crushed ribs in the left top wing panel and re-cover it. I spend a good morning futzing with my CAD program and my soon to landfill fodder printer trying to match the color of the existing decals and get two to print. Succeeded at that and then spent the rest of the day trying to get my blood pressure down. One of the wheels went missing during the last flight as well as the tailskid. Replaced both of those. Should have started with two new ones than recreate the masochistic process I went through originally. Pictures below are self explanatory. No, those are not martini olives for the benefit of DavidJP, they are the shock cord fairings. I could have used real martini olives that day...Added some more detail to the fuselage, Vickers gun shell casing ejector chute for one.

The main thing lacking on this airplane is a pilot so I sent off for one of the David Banks pilots. Received in the mail today, Capt. Cecil Axelbender, at your service. Wonderful piece of sculpture and very light like everyone reports. Hoping to have this one flying before the end of the month.

 ; ;D   started the bell p40.  this is the GAR version with the box and attached formers otherwise it is identical to John's original design.  Don't know if GAR still exists.

i have to go slow because it can be very complex if i add the flexible controls.  i will want to have some movement so i can do flight adjustments.
so far elevators are under construction and rudder is next. then i move to wings and work from there. wood's nice and light so i'll be careful cutting it out.

i haven't heard from john in over a year so I hope he's OK.  i am thinking of him and the fun we had when I was in Floridad!

Busy day at Lurker Industries

Elastic bands: 1 box. Wings for the securing of. Ordered. Ten quid.
Bought a mixed bag from the village post office this morning of which precisely 2 were of use for Stickleback.  That worked out at  60p each (12/- for heavens sake!) . Hunted around the various stationers in my nearest town later on and finally turned up a place (a printers) that could supply single sizes rather than mixed bags.  So if anyone needs thin(ish) 110/115mm long elastic bands in future please contact Lurker Industries who will be pleased to supply small quantities free of charge.  Actually I'm serious about that.  It's a large box and they'll perish before I'll get anywhere near using them all.

Got another print of the KeilKraft Minimoa run off.  Only 2 quid at the same printer supplying the elastic bands.  This print is scaled to about 75% so wingspan will be just over a yard instead of just over 4'.  Be interesting to see how well or even if a scaled down version will fly.

However the most important thing was getting some proving flights in for Stickleback.  You will see from the attachment that the proving flights went pretty well, by my standards anyway.  Still a wee bit stally, but at the current all up weight of 80g (of which 16.8g is ballast) the glide ratio looks to be somewhere between 1:10 and 1:15.  Not sure how good (or bad) this for a model but IIRC a K13 training glider has a glide ratio of about 1:40 and competition soarers have glide ratios somewhere about 1:60 so as a glider builder got some way to go yet.

John Hook can’t be that far from you Lurker.  I think he still does his indoor meets and you could even go and join the hardies who fly at Beauieu.

Nice Glides by the way.  I have built a couple of Mimimoas - one in my very early teens and heaved it off a slope in the local park.  It went very well - flights of two hundred yards were easy! Needless to say it was a bit of a bodge so a well built model should go great.

i did this in the following steps
1 put double sided tape onto the fin (stabilizer)spar where the two parts join
2 run a small wire (.001) down the length of the spar and cover the fin (or stabilizer)
3 peel off double sided tape and stick rudder (elevator) with the double sided tape.
4 cover the part   

it seems to work. now for the wings.

WACO 'N'  25"  EASY BUILT SESQUI-PLANE BIPE

     I completed this purple WACO "N"  fixed tricycle gear model in March 2015.   She already is a "stitched up battling broad"    ;)    , as the front wheel broke, ripping the whole mounting plank off, on my first test glide (3 yrs ago), with a HORRIBLE  silence piercing "CRACK", and couple of subsequent miserable attempts, requiring scotch tape.   I was up late last night and worked on her from midnight to 1:00 am.  I cut off her front wheel at the fuse, and tied up a new rubber motor. The main gear wheels were built detachable, with a Mortise and Tenon joint, so now I am abandoning all virtue and tradition, and I am trying to fly her without the fixed landing gear.
     I did about 20 test glides and short flights before dark - there was still wind - and I had to add  3.70   grams of weight to the nose.  Then I gradually increased hand winds up to 110 winds - best flight was 33 feet and 6 seconds.  She flies out nice, runs out of rubber, and plunges to the ground at 45 degrees.  The grass in Jackson Park had only been mowed once, and with rain a couple of days ago it is  now 6 inches and thick,  and I had no damage.  Tomorrow the wind is forecast to be 4 mph gusting to 11 mph in the morning, so I better get out to that Cricket Wicket before the players take it over - they took it over at 10:00 AM this morning!  This time I am bringing the winding stooge.    >:(    The plane weighs  30.63   grams AUW (all up weight including clay) without LG and without the nosecone,  the front wheel weighs   1.74    grams and the two wheels detachable main gear weigh  6.03   grams.
     Total wing area is  119   square inches and with an AUW of 30.63 grams, gives a wing loading of  0.25  grams per square inch.    That sounds really low - ??

Yes really nice Richard - I like your photo booth - you seem very committed.  Good to see.

Today - well yesterday in fact I did some work on the Ryan Lone Eagle.... this is a 25ins span version and will probably go electric.  The designer suggest that the wing is in one piece and incorporates the cockpit glazing that extends over the wing.  This seemed a bit complex to me  so I have used a centre section intending to make a two piece wing and fit them to the centre section.   A lot of timber in the fuselage!  The other picture shows what the nose end should look like.... the cowl looks pretty utility there.  Mine is a bodge of bits of sheet hollowed out.

Post by: DHnut on May 06, 2018, 05:28:27 AM
David,
         That is an interesting shape. I agree a two piece wing makes a lot more sense and simplifies transport a lot. Are you going to use rubber bands to provide holding force to the wings?
The jury is out on the use of cabon rod joiners except for small models because of the lack of give. Wire is now the preferred choice.
Today we flew Cloud Tramp in conditions that are strangely reminicient of the UK. ie lots of wet. We all had a lot of fun and some good flying took place. If you are at the FF Nats or Mayfly on the Sunday we may catch up

I recovered my Cloudbuster.  I filled the tub with water and sunk the model in the water for about 30 minutes and was able to easily remove the old tissue.  I used my low wattage laser to cut out the tissue graphics.  I found a Flyboy logo on line and since I think this model from guillows is Flyboy I used it.  I printed on white tissue and used a trace function in my laser software to cut the outline of the graphic.  I use Elmer's craft bond glue stick to affix the graphics, it is repositionable then I use Krylon to seal it down.  I take a cue tip and run it around the edges to make sure it is bonded.  Came out pretty good.

     Well, we got up early, ran the dog, got the gear, stooge, plane and backpack ready, grabbed the dog and headed out to the Cricket Wicket at  9:00 AM.   Winds were  4 mph  from the South, gusting to 7 mph,  57 deg F,  and high humidity of 88%.  The tissue was sure wrinkling and sagging.    :P    Did a lot of short flights, and had to put about three more grams of clay on the nose.  There was so much dew on the long uncut grass ( I had to wear my rubber "wellingtons"), that every time she landed, I had to physically wipe the water off of the prop, and nose and tissue, and wait for it to dry,   :-\   upside down in the stooge (the sun was shining).     The Cricket wicket boys showed up before  10:00 AM, but let me try a couple of more flights.  Sure enough, I finally, on the second last flight, got a perfectly level, straight out, and slight circle left, flight of 11 seconds,   ::)   and these young men were filming me with their camera, so they may send me the video of the one good flight later tonight, and I will snip a couple of proving pics out of it.   Now I know it will fly - I just have to get out there for more flight trimming, and now to braid up a powerful  3/16"  motor - the  1/8"  motor I started with did not have enough power, but I had a  3/16" motor with me already tied up.  Good thing ...    :)

Hi Richard, I think that's the 2nd time I've read you mentioning that  cricket wicket. Does me heart good.

Today I flew my F6F Hellcat, the only airworthy model I have. There were bullocks on the field, and they love an excuse to stampede -  but I had to do something - rare weather, and the farmer's told me he'll be ploughing the field soon for maize. Could be my only flight of the year apart from 200 turn trimming hops on my own grass patch.

Anyway, the bullocks were distant so I took a chance. The trouble was that although I put a new 25" motor in, the model really needs re-trimming from scratch, being stick-and-tissue and having endured a very long winter of wild swings in temp and humidity.

Off she went. . .in a lovely straight line. 700 turns which is under half the safe capacity of the motor.

https://youtu.be/5lVko7KeV3I

I was fortunate in that the bullocks didn't take an interest and that the grass was short, and visibility fine. The model flew on a few seconds after I stoppped the camera, but I found it fairly quickly.

     Hi Stephen.  Yes, that WAS a lovely flight straight out with that nice Hellcat  perfectly sunlit.  So you took a chance with the bullocks, eh?     ;D   LOL   I gather you have played a lot of Cricket.   That Cricket Pitch is my only flying field, and it is circled all around by large trees, so one must get his miniature aircraft to fly in a circle, and fly low - I made a perfect landing only once on that lighter green strip of artificial grass, "Wicket",  where they throw the ball and swing at it with that paddle-like baseball bat.   :)

Sorting through the pile of busted models from 2014 in order to get back in the game.  Looking for ones I could get back in the air with minimum expense and time.

Discovered my Satellite 220 and 1/2A Super Pearl are still 100% flight worthy!  Also didn't think I had any whole CLGs.  Wrong again.  I have a totally intact Sting 18 and another needing only a new stab and fin.  Found a piece of 4.4 lb. 1/16th.  Dope is drying on new stab and fin.  it should be back flyable tonight.

My Embryo Endurance model is also airworthy as well as a Flying Aces Moth.

Progress!!

Liked the sanded cricket bat! :D :D

The problem with county cricket and tests is how long they take.  As a kid they were great for me, as I could cycle the six or so miles to the County Ground.  I would lie on the grass all day, watch, sleep, eat and repeat, then I would go home and my mum (having been at work all day) would ask what I had been up to, when I told her I’d Been at the cricket she would be fine, if I would have said I did the same at home she would have hit the roof!

We regularly go to see Derbyshire in the T-20 “Blast”. It’s pretty exciting you’ve got to hit out, you won’t see so many 4’s and 6’s on the same evening in any other format of cricket.  A few beers, pop for the kids and a picnic complete the picture, you can’t have a better summer evening IMHO...

PS Real men (and ladies nowadays!)  hit the ball with the bat in the summer and with their foot in the winter...  ;D

On the aeroplane front I finished up the plan and Instructions for the VMC Pilot...

Well it were last Thursday rather than today, but I looked out the window and said to the missus "What with those big red vehicles with flashing blue lights racing towards that other plane stopped half way down the runway, we might be here a while." Good job I'd paid extra for seats with one inch more legroom, as once the stricken bus had been towed away, our 22 year old captain said that we now ourselves had a problem with the leading-edge flaps (I think he meant 'slots') on one wing, and I said to the missus "While we could probably get away without them, it would be unfortunate if we only discovered the problem once coming in to land at the other end when one side worked and the other didn't." Once the control-surface software had been reset by less smartly dressed people in hi-vis clothing, we then needed to top on on fuel, as we'd wasted a little hanging around but also because - as it transpired - we then tried to break the sound barrier to make up lost time.

I entertained myself in the meanwhile by flying a Jart off steep cliffs in high winds on the Picasim simulator on my smartphone...

To answer the Island Flyer question,  It is a simple, great flying, small rubber model designed in the northwest by Clive Winker.  The plans are on the plan page. At the northwest free flight contests in Oregon there is always an Island Flyer Mass Launch. I lost mine last year to a model eating tree. Need to start another.

...Yes, that's right:  playing concertina for my wife's ladies' morris team. An afternoon of sheer hard toil in the high octane, no holds barred enviromment of a village church fete. And not just morris dancing mark you- it's the Mayday holiday so some pretty intense maypole dancing went down too. Scones were buttered, cake was sliced, and copious amounts of class A tea were consumed.

(Incidentally, when I joined this band several years ago, a flowery hat was de rigeur. I noticed today though that I was the only one still wearing one. I may have to have stern words...)

You should go to one of the big Flying Aces Club meets if you want to see how it's really done.

Can you explain what you mean by "ounce inches"?  Is this to do with using a torque-meter or otherwise?

Jon, correct, those are readings from my uncalibrated home-made Koethe-style torque meter. I suspect it reads low as I seem to break motors if I wind to the torques Don DeLoach and others recommend.  Mostly it helps me wind more consistently.

Got 'seen off the premises' (a good bowl in a strong southerly) late afternoon today by the residential bull. Had only been flying - slope soaring - for about fifteen minutes when the manufacturer of some recent-looking cow pats came along. Yes, he was the other side of the barbed-wire fence, but so was the only clear landing zone!  Under the circumstances, I was compelled to acquire more advanced landing skills, and rip the tailplane off its nylon mounting bolts in the process. Said bull kept pace with me for several hundred yards, albeit the other side of the fence, while I pretended to have not a care in the world, then I pegged it and cleared a metal gate just before the barbed wire fence ended in a bull-versus-human gap!  Barstard!

Went flying with Jack Plane and his No.1 apprentice at Uffington.  Overall a fun time was had by all and I came home with an aeroplane that had proved to be a very good flier but didn't survive the last tow of the day. Chewing it over with JP best guess is a combination of an earlier very bad attempted tow launch with consequent very heavy landing (it required field repairs) resulted in a weakened/damaged port wing which couldn't handle the stress of over enthusiastic acceleration and general poor launch technique by the pilot.  Who'd have thought an old bloke could run so fast over rough ground eh?

JP has film of the crack-up which I hope he'll post.  There's rather a strange beauty in a detached wing spiralling slowly out of the blue.

And even better this month's BMFA mag was on the doorstep when I got home with and it contains a very, very apt cartoon. :D


Title: Re: What Did You Do Airplane Wise Today?
Post by: Jack Plane on May 12, 2018, 12:35:21 PM
Here's the footage of the crackup launch:  https://photos.app.goo.gl/qaj2j6ybi6DR8tUS2 (https://photos.app.goo.gl/qaj2j6ybi6DR8tUS2)   :o

I have to say, however, that the immediately preceding tow-launch had produced a truly magnificent flight which seemed to go on forever - which I hadn't filmed, so it was my fault for egging Lurk on for "just one more wafer" of a flight!  ;D

But, as Lurk says, it was probably a rather hard nose-in on an earlier unsuccessful launch (where the tow-ring hadn't detached) that had weakened the wing-structure, so it was all just a matter of time...

Great, old-school, massive-fun, stick-and-tissue FF model gliding.


Title: Re: What Did You Do Airplane Wise Today?
Post by: TheLurker on May 12, 2018, 12:52:22 PM
Ah, that's interesting.  The wing parted company quite a bit earlier in the launch than I thought it had.

Still puzzling over whether to do a complete rebuild of the port wing, or at least most of it, from rib 2 out, so I can stick the new wing section directly to the existing rib2 where the sheeting ends or to try and splice the what's left of the old wing back in.  I can see it being tricky to get the dihedral and incidence right on a splice and I'm not sure I'd trust it on a tow. Or mebbe build a single new (short) bay from rib 2 to 3, and insert that?

One for debate.  Any and all comments and opinions invited.  Or you can just pour yourself a drink sit back and enjoy the debate.

Well, I am sadistically "sort of" glad to see I am not the only one smashing up models.  :-[   :o   Now I see what slope soaring is like - very graceful planes.   I broke a wing off my 22" Sig "Cabinaire"  high wing cabin plane, and I glued spar extentions in it, and it all looked good, but I think one wing has more dihedral than the other - my mistake - and it never flew properly again - and it was a great flyer - standard 35 second flights and the best was 57 seconds.   Good luck with your repairs - I want to see how you do it.  ;)

Ideal model for bungee launching.  The Peterborough club site gives details - look for Hi-start comp rules.  Either that or build something like a Lulu for tow-line launching.  Small gliders are difficult to tow up.

Nah you're not alone.  Not by a looong chalk.  Frailty, thy name is balsa. :)

We got one text book tow-line launch and flight out of it and any number of really good hand launched flights before the crack-up so I count today as a success.  Some models don't even get one good flight before they're destroyed beyond repair and this one is fixable.

Yeah I'm rather taken with it, but I do have a weakness for slab-sided stick and tissue FF gliders.  It's West Wings' semi-scale take on the Slingsby Swallow.  The NMF is a nod to the livery the Air Cadets used on the Swallows they flew; mostly silver with fluorescent orange patches. It's a nice design and reasonably straight-forward build but it has to be treated as a scratch build rather than a kit.  Will post a short review somewhere hereabouts tomorrow.

You're probably right about the wing, but I'm going to give the "short single bay" approach a bash first.  I have the first set of ribs that I cut and discarded to hand and as the misalignment on the rear spar slot that caused them to be dumped won't matter in an independent insert it will give me a rapid "fix" fairly quickly.  If it proves a washout I won't have wasted too much time and can get on with a new wing.  Just as well I hadn't taken the plan off the board eh?

The first one I built as a youngster was the Airflo glider from the Eagle book. I'm going to build another at 36" instead of 24" span. I might have to get this kit just for poohs and giggles as well as the VMC Osprey (did you design this one too Andrew?). I'll enlarge the Osprey to 36" too.

Yes I designed it, it was fun to fly, although a bit limited in performance, but to be honest my launch technique is probably well less than parr.  it’s very small as gliders go so enlarging it might be worth a go to see how it performs in more experienced hands.

Memory fades, it might have either flown away, smashed on launch or met its end in a tree somewhere in France (which happens a lot to me!), whatever I certainly don’t have the prototype anymore.  I built a second to try Ezedope on which was used in a VMC video and that also flew petty well.  I know that one met an end when it was on my bench when something fell from the shelf above!  :'(

I think that models need protecting from me at times  :D

Hi Lurker.  I was so impressed   8)  with that  graceful "Stickleback" Glider flight, and the view of the newly planted farms in the countryside for a background, off of  "Uffington"  Hill, ( in the UK, I presume), I snipped a few still screen captures from the video.  You have now got me interested in slope soaring.   ;D

...the VMC Osprey...
...Airflo...
Don't believe Mr Darby when he decries its performance as limited.  The standard size VMC Osprey is a great little flier in calm air so a 36" span version should do really well.   Took mine to Uffington yesterday as well as the Swallow and JP's No. 1 Apprentice got some really nice hand launched flights out of it.  Noticed JP getting the odd sneaky flight in with it as well.  :)

If Andrew & VMC could see their way clear to do an Osprey kit at 11/3 to perhaps 11/2 current size I think they'd have an even better "first model" kit on their hands than the current incarnation.  Straight-forward construction, not too big for the kitchen table and big enough to fly "better".  How about it Andrew?  A slightly modified Osprey fuselage with a larger wing? The VMC Condor?  

Oh dear, that's torn it. Another one, the Airflo, to add to The Lurker Industries Aviation Company's build programme. :)

...stills...  ...slope soaring...
Nice pictures of an aeroplane and scenery, but such a shame about the gormless idiot in the hat ruining the view.

Slope soaring? Nah, that was just flinging a glider and hoping, no RC was involved, but for fun flying I think it's difficult to beat. The aeroplanes are cheap to build (no motor, airscrew or RC gear), much simpler to trim than FF rubber and even a poorly trimmed glider can give you a reasonable flight.  If you don't do something inexpressibly daft (see above: tow launching and how not to do it) even bad landings for gliders are generally soft.

Post by: cvasecuk on May 13, 2018, 05:04:11 AM
Actually, that mention of slope soaring gives me an idea. Why not trim it fly straight and see what happens!
As you know, the Swallow plan gives details of micro RC installation and it did work well in winds up to about 10mph but above that it could not penetrate.

     Well, the Cricket guys were playing all day today, so just for the heck of it, I tried some night flying with the  17 1/2" Air Camper -  three flights of 6 or 7 seconds on a 7" braided motor with 100 finger winds - too windy and gusty - winds  9 mph gusting to 14 mph and 93 % humidity, and way too much standing water in the grass, along with the dewfall, in the Cricket Wicket - it really rained the last couple of days - standing water all over the park.   The plane's tissue was way too wrinkled and soggy to begin with, and moreso after landing in all that water.  I had to settle for a couple of handheld night pics.  There sure were a lot of different colored stars in the night sky tonight!    ;)

. . .winds  9 mph gusting to 14 mph and 93 % humidity. . .
Y'know what? The forecast relative humidity here for this afternoon was 38%. I check nearly every day and I've never heard of such a thing. The sky was incredibly blue and the vis. was exceptional. Average humidity here is 80%; even 60% is unusually dry.

I got another couple of flights from the F6F. We've had a run of several fine days of weather, with calm evenings - a better run than I can remember since mebbe 2014. The bullocks were elsewhere so I wound on 980 turns and tweaked some left rudder to stop a straight-line flight as in reply 479. The first flight is the 'airshow' flight; a low-level stall or two for thrills and a close pass for the cameras. The thing is, I'd increased the propeller blade pitch to 36° at ¾ radius [P/D 1.7], and had shimmmed in some upthrust to compensate for the commensurate decrease of thrust. This wasn't needed, obviously.

https://youtu.be/meLX9YBpO5c Edit: just noticed the sound goes wrong and  blasts into white noise after the first flight - will try to sort this out tomorrow morning.

The lack of an aerial mast behind the cockpit is because the  motor peg is in a position that requires the model to be mounted in the stooge upside-down, and the mast fouls the base of the stooge. I was in a rush so neglected to fit the mast after winding.

The second flight (also 980 turns, with upthrust reduced) is interesting (to me anyway) because the model ran out of turns as it landed. This allowed me to measure the average RPM as ≈ 1180. This low, chugging rpm suggests that a 90-second flight is possible.

The nasty keening whining note in the background is from tractors mowing grass for silage.

     Hi Stephen - great videos of your Grumman F6F Skyraider !   I must say that the first video was quite exciting - kept me right on the edge of my seat - when it came back in right in front of you and swooping low, just missing the  grass before climbing out again, and another low swoop and then recovering and finishing the flight out like a champ!  Nice scenery backdrop for that one too !
      After watching your flights, I went out with the dog at  7:00 PM expecting the Cricket Wicket to be full, and to my astonishment, there was nobody in it.  We finished our walk and came home and packed up the backpack and stooge and headed out forthwith, with the  30" Dumas Rearwin Speedster at  8:00 PM  (sunset is at  8:42 PM),  temp 70 deg F (feels like 81 deg F), winds from the South at 8 mph gusting to 12 mph, and 83% humidity.   I then found out that that 30" Rearwinn Speedster CAN REALLY FLY  even with wrinkled soggy tissue and 8 mph wind, unlike the  17 1/2"  Air Camper.
       I had a total of 13 flights, all of 15  to  24  seconds,  on 450 winds on a Braided (at rest) 15" motor of 3/16" rubber.  And I tied my 24 second record for the Speedster!   I got 12 pics, of which only 6 are not bad.  It was getting pretty dark, but I saw no bats flying around.  And we got home at 9:00 PM, same temp, wind, and humidity, having completed another stress relieving fun flying session - I have to really jump   :o  at these chances to fly.  
       Now I am wondering what I have to do to get longer flights - that motor was made from two strands of  3/16" rubber, each strand 30" long, or one loop of 30", braided down to a resting 15" (four strands each 15"),  braided motor (I think), and I am afraid to put more than 450 winds into it ...  ???
Keep 'em Flying !

I've re-uploaded the video referred to in post #537.

https://youtu.be/4G4ir3jsXs4  It works for me now. I'll delete the broken one shortly.

Hi Pete, John Richard and Andrew, yes, it's a smoothie all right, the F6F. The evening was very calm, adding to the smooth effortless look. It'll be interesting to see how the P-47 compares whenever I finish that and have the chance to fly it. Could the Hellcat be the best for stability and potential duration of any of the low-wing single-engine WWII fighter types so popular with modellers? Remembering that this model has scale dihedral, scale tail areas and scale-ish wing thickness, I think it could be. . .Not a great beauty, but y'can't have everything :).
 
Those are lovely evening shots LWM.

Good to see that you are getting your flying in Richard. It looks very pleasant.

The stability of the F6F is surprising. The full size appears to have a proportional larger tail than many other WW 2 aircraft but it appears very stable in roll as well. There is a lesson there somewhere.

A motor of 4 strands 3/16" x 15" long should have a max turns of about 850 so you should be OK to go to at least 750.

Strung the last rigging wire on this SE5 this morning. This one is 13 years old and has been through a lot so the finishes and tissue are a bit worn. Rebuilt the upper wing on the left side, replaced a wheel and tail skid, added a David Banks pilot and a few more details. Power is a brushless motor (ancient) with a LiPo running through a Smoothie timer (also ancient). This will be my power ship for this season.

Post by: Rich Adams on May 15, 2018, 09:43:43 AM
Stephen,

The Hellcat is a great machine for FF. I built one that flies similar to yours. Do you ever exerience a wild wingover when launching into a fair wind?

Richard, love that you're out there flying at all times of the day. There are charts available for determining max winds on the rubber. For 2 loops of 3/16, I use 72 turns per inch as maximum. If you want to push it some day, build you a test motor from the same batch of rubber and wind it till it breaks. Then you'll know for sure.

Post by: Crabby on May 15, 2018, 10:17:04 AM
I get the idea that Richard, you fly in a small area so you have to mind your winds or lose a plane. If that is the case, try Google Earth and find your area. Look for big fields then go on a safari. I did just that when we moved here to Palm Bay, and literally stumbled upon the biggest free-flight area in the south. I went out and they just happened to be holding the King Orange there. Big shots travel here to fly competition. Funny thing they all remembered my Dad, "Thee Olde Man", who drove up from the Florida Keys yearly to fly there with his club, I went through his photo album and right there is four pages of photos from Palm Bay. Finding a good place to fly is just as important as building. Thee Olde Man lived in an area surrounded by saltwater so he built float planes. Guys are getting bored with these pics but I never tire of posting 'em to show what a model madman he was! I am impressed by all the flying you get in Richard, and a broken plane doesn't seem to bug you too much.

     Hi Stephen.   The Cricket players have not switched to American "Baseball" yet - there are no night lights for the Cricket grounds, and only one Baseball Diamond, out of four, has night lights.  Stephen, I  was so impressed with your two Grumman Skyrocket videos, I "snipped"  18  pics out of them.  Here are the best six - with the sun just right, backdrop just right, focus just right, and neat action shots , making for the best pics.

John, I use small ferrules from a local store that sells jewelry making supplies. They are silver plated brass and come in two sizes. I use the smallest size (0.032 ID) for single wires and the next larger (0.047) for the double wires. I pre-flatten the larger ones and spread the wires out as I install and crimp them with either needle nose pliers or the crimping tool they sell. Handy little things since they can be used wherever you need a small bushing for standard music wire sizes.

REARWIN SPEEDSTER FLIGHTS May 16 2018

     Well, Trapper and I just got back from Jackson Park at  9:15 PM - we were just walking around and laying around, enjoying the last couple of hours of light on this beautiful summer day.   Sure enough, they mowed the grass in the Cricket Wicket in the afternoon after we were done our Speedster flights from   11:00 AM  until   1:00 PM.   Good thing we got our flights in,   :)  because I don't know if the plane would have survived the "full song" cartwheel crash into the shorter grass.  :(  
     That is two evenings in a row now that I have not seen any bats flying around - very puzzling and disturbing ... we did see one "Common Nighthawk" - 23" wingsapn - flitting and fluttering and darting around, and maneuvering acrobatically, with its buoyant and erratic flight, high in the sky eating insects, though.
      Here is the best pics of today's Speedster flights, including the "money shot" (finally), when it flew right over my head as I was panning with the digital camera.  I thought I had missed the pic from the "beep beep" of the camera catching the image, but I did get it.    :D

This is a pic to show confess what a quack airplane surgeon I am. Everyone who reads my posts must know how fond I am of this little MIG 15. It is the younger more buxom sister of the pistachio version I built 10-15 years ago. The younger sister was a pain to deal with but after some profanity and a Lou Gehrig type launch I got her flying in a consistent manner, albeit a screamingly scale mach+5 manner. She lived for about 20 years before she left home. This one is no different, twice the size, and when she is good she is very good when she is bad, she is just f'n awful. Last time out I made a series of adjustments and had her finally acting ladylike, and after a fantastic 2.5 min flight, I got a call to get home. When I inspected her I found the whole front end was about to fall off, held on only by bits of tissue. Here is my scab fix. It's X-rated, but this bird is gonna be able to take what is dished out. I just could not perform euthanasia, after that last flight. My sadly neglected Tripehound looks on while I dabble with my past love affair!   KEEP ON TRUCKIN, LASTWOODSMAN!

Prosper - the reason I ask is that my Hellcat flies much like yours and has broken the 2 minute mark on several occasions. However, If launched into a fairly stiff breeze with the nose pointed slightly off to the left, it will sometimes just roll over on it's side ending in a full bore wreck. Of course, this is with the thing would up to about 1400 turns so there is a lot of power involved. If I launch to the right of the wind there is no problem. Probably just a misplaced torque issue.

 ;D p 40 is now finished and i got flight tests in before the ran.  YEAY!!!!!!!!  the plane weighs in at 70 gm so it is pretty solid.  it does behabve fairly well.  I need a bigger stretch to shake it down.

I would call this kit ADVANCED because although GAR simplified it you have to understand what the parts are and what the drawing tells you. you also must take it in stages to get it right.

i would do this as a scratch build and try to lighten the structure by shaving down the thickness of the tail and simplify the belly.  you need an 8 inch prop. not 7 as supplied with 2 loops 3/16 rubber.

     We flew the 30" Rearwin Speedster again this AM,  May 23 2018, the weather was so nice.  We got out to the Cricket Wicket at  11:30  AM -   70 deg F (feels like 75),   winds from the North at  8 mph  gusting to  12 mph,  60% humidity.   I got in  6  flights starting with the  6 strand  1/8" motor, each strand  23"  long.    The first flight was  8 sec  on  600  winds - it was porpoising all over,    ???  so I added some more clay to the nose and a bit on the outer right wing tip (left hand circles).   The next flight on  600  winds went  16 seconds and a circle and one half.   It did not seem to have the power needed in the  8 mph  wind,   :-\   so I changed the motor to the more powerful "braided",  14 inches at rest, motor of four strands of  3/16"  rubber, each strand 18" before twisting and braiding.   Now the plane was continually descending (3rd flight) for a six second flight on 450 winds, and landing with a lot of turns left in the motor.   So I took the nose weight off and added more up on the right elevator tab.    Got 16 sec on the 4rth flight on 450 turns, and  18 sec on the 5th flight on 450 turns running out the rubber on a circle and one half flight.  On the last (6th) flight I only got 14 sec on 450 winds running out the rubber on a  3/4  circle.   The motor seemed tired and weak, and we quit because it was getting too windy.   At home, I took the motor out and examined it - one of the four strands had 3 nicks in it, and one of the other strands had one nick in it.    :o :o   Time to braid a new one ...  But it was a perfect day,   :)   and no major damage    ;)   - in addition to mowing the Cricket Wicket yesterday late afternoon, they had also mowed it again today this morning first thing when I walked the dog.

     Well, I just took all your advise guys - made up two braided and LUBRICATED motors.  Stretched three times its length for two minutes and lubed while stretched, rested for 10-15 minutes, then stretched for four to five times its length for four minutes, as per Don Ross' book.
      The first one only ended up being  10"  long at rest, twisted and braided up from four strands, each strand  21"  long, of  3/16"  rubber.  It was too short for my  15"  prop hook to rear peg distance.   Then I tried one of four strands, each strand  28"  long of  3/16"  rubber, and this one, after lubing and twisting and braiding, turned out to be the perfect length of   14"  at rest.  This will now hold the nose block in also.  I just put this motor into the  30"  Rearwin Speedster - we're going flying !!!

     Well, that  14" braided motor for the  30" Rearwin Speedster did not work out too well today May 24 2018 - it was way too powerful because of how I wound it incorrectly.  It was so tight, I could hardly put in  150  winds, it was so strong.  Thinking about it now, I was lucky I did not "accordion" the fuse !!!
     On the first flight on 225 winds it flew wildly high and ran out of rubber in  9  seconds.   I then put some extra nose weight in.
     On the second flight,  to my shock and horror, she proceeded to furiously fly "like a bat out of hell",  and drove herself, and buried herself, and I mean buried, and tunneled and augured right in, deep into the very thick, bushy and leafy, end of a branch of a tree - look for the little patch of brown right in the middle of the pic of the trees -  in behind and left of me, on a blazingly fast, five second left hand circle flight.   I had to climb way up, and it took a LOT of shaking of that branch to bring it down, with the end result of many tissue wounds - 8 to be exact - that had to be scotch taped up.  I now see why people use poles to bring their planes down out of trees.   I put more weight in the nose and on the right wing tip.
    Third flight 135 winds and another extremely fast 5 seconds of a flight circling left - so I took out that braided motor.    
     I changed the motor out to the  6 strand,  1/8" rubber motor, each strand 23" long and NOT braided.
     Fourth flight now 600 winds and it got into the wind and hit the ground after 4 seconds.
     Fifth flight, I took off more nose weight and on 600 winds, I got a  9 second flight.   Not enough power and too windy now - so we packed up and went home before the Auxiliary Police could catch me and kick me out, for flying planes in the park.
     The mistake I made on the braided motor is as  follows.   When I stretched out the 4 strands of  3/16"  ( or two loops ) rubber, instead of winding clockwise, then folding it over on itself and allowing it to twist and braid up, instead I wound counter-clockwise after stretching, and then folded it over and allowed it to twist and braid up.  This resulted in a motor with way too much torque right from the first crank of the winder, and an inability to put a lot of turns into the rubber.
     I think my models are giving Crabby's models a run for the Queen of the "Stitched up Battling Broads Beauty Contest".    ;D  ;D
     Back to the Drawing Board ...

I don't know Richard, but that sounds like you've made a motor that is way too thick, and it is running the turns off far too fast. Your yellow K&P winder should have no trouble with 4 strands of 3/16", whichever way it's pre-tensioned (or braided).
However, it would be a real struggle winding an 8 strand motor........

     Hi glidermaster JB - thanks for the  tip - now that I think about it, and look at the diameter of that thick rubber motor ... it IS WAY TOO THICK !!  In fact, I just made a braided motor out of 4 strands of  3/16", each strand  28"  long, and it braided down to   13 1/2",  ( and it is way too thick ), and I just tried it before dark on up to 115  finger winds, and the plane goes very fast and high and a tight left circle, and the rubber runs out, and since it is sitting way up high in the air, gravity accelerated it,  as it dropped straight down into the ground heavily, and I heard that familiar "CRACK", which split the wing strut mounting plate on the fuse -  bashed in, and up, by the pressure of the crash from the rear top of the triangular balsa trouser - but a clean crack right down the middle of that mounting plank,  and it seems to fit right back into position nice and tight, so I think I can just glue it up overnight.
      The cranks on that winder were almost impossible - I had to pull the rubber out, and crank 1/3 of a revolution at a time on the handle, while moving the rubber back into the fuse,  and do this over and over to get the last 5 complete revolutions on the  15:1  winder - it was so hard, I only got  a max of  15  cranks  or  225 winds.   ??? ??? ???
  Back to the drawing board ...

Went flying yesterday with a focus on jetcats and trying out a new GoPro.  Conditions were nice and had some very satisfying flights:

https://www.youtube.com/watch?v=r3Q0muu1-3w&feature=youtu.be (https://www.youtube.com/watch?v=r3Q0muu1-3w&feature=youtu.be)

I also tried a new prop on the Tempest (Sig 7" paddleblade with the blades narrowed by cutting a tapered section off each blade's TE) and a new motor on the Navion.  Both showed promise. Tempest flew well with no trim changes from my previous 7" Peck prop other than a bit of downthrust (stock Sig 7" generated a lot of torque for not much thrust) and had to retrieve the Navion from the landscaping in front of the school beyond the end of our field after a nice 56-second flight.

I'm now tempted to trim the 7" Sig props on my Tigercat to match the modified Tempest prop.

Took advantage of the absolutely glorious1 (south) British Bank Holiday weather over the last couple of days to try patching up the Swallow's wing whilst waiting for those awfully decent chaps at SLEC to send on the new wood for a brand new wing.  Words are going to be had with the head stores wallah at Lurker Industries regarding his slackness in maintaining an adequate supply of raw materials.  Poor show that man.

Seems to have gone together quite well2, a bit of wobble in the LE, but the wing itself looks true.  Not sure it's going to be up to a tow launch, but there are some nice steep hills hereabouts suitable for hand launching and it'll be nice to have it at least partly airworthy until I can get around to a new wing.

1 - Warning.  Post may contain traces of irony.  Shares can go down in value as well as up.

Today I am sanding a former for a new canopy for my Comet 24" Thunderbolt, which I am refurbishing, in between refurbishing various other veterans,such as the Guillows Me109 (also approximately 24 inches but to a different scale (1:1/16) and the Guillows Spitfire to the same scale as the Me109. In spite of photocopying the side view of the canopy on the plan and gluing it to the block I carved, the curve is not right and needs quite a bit of sanding. Fortunately sanding is quite a soothing pastime and can be fitted in between the odd cup of coffee and visiting the computer to watch thrilling pictures of other people's  planes flying much better than mine have ever flown. Hope springs eternal. In its day the P47 provided me with a lot of pleasing flights and I hope it will do so again. I may well build another and try to build it lighter. Sometimes I think that would be faster than a refurb.

Finished making repairs to a Fokker DR-1 from the Midkiff line of kits. 22" span on the top wing. This was flying great until it hit the only obstacle on the field (naturally). The kit is well done and I highly recommend it. Flies on four strands of 1/4 turning a 9 1/2" prop.
The other one I cleaned up is a Robert Copland "British Champion", his 1939 winner. Reduced to 36" span to fit the FAC rules and built with a pop up tail group as the major deviation from the plan. Wings are remarkably stiff in torsion due to the thick section leading edge acting as a box spar. Flies very nicely on 14 strands of 1/8 swinging a 14" paulownia prop.

Lurk I believe that repair would be good for a light tow or light bungee (ALA Peterborough). One trick that may help if you wish to tow it again is to use standard sewing grade cotton thread which will give you a safety factor - it will break first. I used this on a 30" tow line glider. It worked well.

Thanks John.  I was wondering about trying a bungee launch, but I like the sound of cotton trick.  Finding cotton rather than nylon based sewing thread is going to be my next challenge. 

Meanwhile at Lurker Industries' principal manufactory.... "Where's your sewing box dear?  Have you got any old proper cotton thread?  Why?  Oh, no reason, no reason. Just wondering.  What do you mean, 'Is it for your blasted aeromodelling?' I really can't imagine why you'd think that."

Richard - both of those are pretty good - the Copeland building wise of course is quite a challenge.  Well done.

Chri$ - a fiend of mine who has been flying FF models for about a hundred years uses a "home made bungee" for larger gliders - two 7.5m lengths of 3/17th plus 50m (or for SAM contests 30m) of "line" but first "pretension the lengths of rubber simply to keep them together.  This will tow up very successful gliders (FF kind not full house quarter or one third scale stuff) of say 6ft span etc.  Just in case you decide to go big!

Just back from the "aerodrome" and Stickleback is airborne again.  Managed to get 3 or 4 decent straight test glides out of it, but couldn't repeat that reliably so a bit more cosseting on a non-work night is called for. However on the basis of next to no organised or systematic trimming I'm optimistic.

Thanks John. It was a fun build and the wings and tail look great with the sun shining through.

Crabby, you can buy Paulownia wood from the the World Paulownia Institute located in Lenox, GA. off their website. They sell sample packs of various sizes I bought the 6 boards 1" X 4"  X 36" for about $49.00 at the time. It's now $80.  The boards come to you saw cut so they are a bit rough. They are full dimension boards so 1" thickness means just that. Great stuff. I gave one board away and have made a bunch of props and still have four boards left. Way worth the money.

     REARWIN SPEEDSTER  30"  Dumas.   Well, I DID get out flying this morning, June 1 2018, at 10:30 AM.  I had the BEST flying session yet, with the Speedster ever,  breaking my old record of 25 seconds,  and smashing it,  with a 30 second flight on 600 turns of the  18"  motor,  four strands of  3/16" rubber each strand  18" long, prop hook to rear peg is  15".   To say I am ELATED is an understatement !!
     Weather was  72 deg F (feels like 84),  winds out of the North at  12 mph, gusting to  12 mph, and 83%  humidity, and overcast.   I had 9 flights of two or more circles, which all ran out the rubber and landed softly - very little bending of the  1/32"  wire landing gear, if any, and the grass in the Cricket Wicket was 4" thick and plush.  I tried to show off to my friend and her dog, launched it too close to the trees and not far enough out in the middle of the Cricket Wicket, and the changing wind brought it closer to the trees on the second circle on the leeward side, and the Speedster tried to shoot the gap, as I was pleading for it to "Turn Turn Turn",  between two big spruce, on the leeward side, but as soon as it got in the middle of the two trees, the prevailing wind blew it into the back of the spruce on the left,  after  20 seconds  of flight, and it tumbled down low enough to pick up out of the branches.  Luckily, no damage.   ;)   There sure was a lot of little spiders on that plane when I put it back into the stooge.  Full flight report later in General Forum, Your Birds in Flight.    I am one happy camper !!!   ;D ;D
     AND, I did not even try the longer   20 1/2"  and 22"  motors yet ...  :)

Definitely a photocopy?  Not a print?  It has to be a proper copier/printer that uses toner, as it is the toner, not the ink that re-melts and transfers..

To be honest the best method I have used is using spray mount and sticking the patterns to the wood, it does help to stop the wood splitting and if it does - it gets held to the paper, so you can glue it on.

Spray mount in very expensive though, but having said that a tin has lasted me about 5 years, and I build a lot of models...

Have you tried using a laser printer and ironing that? Hypothetically, that should transfer as well as a photocopy. I used to print mirror image text and iron it onto Monokote to identify my planes, or at least one of them.

I had an art class once where we transferred images from magazines by flooding with some evil solvent or other. Seem to recall using rubber cement and paper patterns at some point or other. As I recall, you can rub the cement to get it off the wood.

REARWIN SPEEDSTER 30"    Dumas kit #326   Flights  June 3 2018

     Well, we got up early at 7:00 AM to go flying and try to beat the rain that was coming at  9:40 AM, and to get to the cricket Wicket (grass was still not cut), before the players got there - they took it over yesterday at 10:00 AM all day, til the sun went down at 9:00 PM.  Trapper would only get a short walk first thing this morning ....  he got his big walk right after we were done flying.
     We got in 8 flights (broke no duration records), starting at 8:30 AM when it was still sunny.  Temp was 57 deg F (feels like 57 deg F),  Winds were 2 mph from the East, gusting to 4 mph, and the humidity was  94%.   We got in 6 flights with the  18" motor ( four strands of  3/16" rubber, each strand is 18", prop hook to rear peg is 15"), the third flight of which, was a 21 second, one and one half circle, with a perfect level solid flight, on 675 winds, and for only the second time (the last time was with the 22" Sig Cabinaire), we got a perfect and best landing right on the astroturf strip of the "Wicket" of the Cricket field.  This was a perfectly "greased" textbook landing, where the Speedster was coming in low and level and straight down the runway,  nice and slow and almost hovering there, and touched down both front wheels, and rode on them for about 10 feet, just the front wheels down, as the prop was winding down, til finally the tail wheel came down, and it then traveled even further for about 7 feet, (all straight into the wind), on all three wheels, to a nice smooth decelerating stop, and sat there with the prop still spinning for about 5 seconds til the last of the rubber ran out.

REARWIN SPEEDSTER 30"    Dumas kit #326     Flights June 3 2018
(cont. from the above post)

     I put in a new bigger motor ( 20 1/2" ), for the seventh flight - it got 22 seconds on a wild roller coaster big porpoising flight of one and one half circles, on 675 winds.   The rubber seemed to lose its strength out in the humidity, right after that.
     The skies were becoming overcast and we could see the rain clouds coming,  so we packed up and walked back to the apartment building, just as the rain was starting ... rained pretty good but stopped 40 min later and Trapper got his big walk in.  Temp now at 9:35 AM was  64 deg F (feels like 72),  Winds 4 mph from the East, gusting to 7 mph, and 83% humidity.  Going to rain off and on all day.  Got my flying in - now its time to do some actual modelling work on jig construction for the wings installation on my Albatross D5  18" plane.    I got some good tips on how to go about it.   I'm itching to get at it.   :)

After a fun packed weekend in Herts I decided to sneak into the school grounds next door and do a bit of flying..for the 1st time this year!  Lifted the trusty flying Lancer of the wall and proceded to install new rubber.. then promptly snapped the wing

Next in line and flying ready was the untested Miles Sparrowhawk.
18”ws. 6” Igra prop. 2lenths of 3/32 rubber. 26.5grams all in

Nice gentle climb and then stalling. Added some nose weight and tabs on the stab to keep the nose down. It got better but it needs more power/rubber. Perhaps a tab or two on the wing.

Lots of potential with this plane.

I put the crosses on my Dumas Eindecker this morning, watched the excellent Mustang restoration programme on Netflix over lunch (as recommended by Bill), and rounded it off this evening off with a cup of tea checking out this highly entertaining drone video (yes really!) which was linked on the Peterborough MFC webpage: https://vimeo.com/273193820

Thanks to all who replied about the iron on photocopy. Quite right. It was printed copies from my little HP printer I was trying to iron. I will try the local copy shop and if that fails stick the copies on with spray mount or similar. At least the local copy shop can print larger than A4. Perhaps I should consider getting a laser printer.

 ;D    cgullows 400 series  spitfire      finished fuselage, started on wings which should be done at end of day.  due to the short nose i'll need 10 grams lead up front . i plan to reduce this by adding spinner and wheels.  i replace plastic canopy with a foam block cut in four pieces and hollowed out to accommodate ballast.  ballast will be reduced as i add other components forward.  oh yeah nose will be sheeted in to add shape, weight and strength.

30"  REARWIN SPEEDSTER FLIGHT JUNE 6 2018

     I got up early because I knew it was forecast to be flying weather, and to make a side right thrust wedge  for the Speedster, after I noticed that I had glued the black plastic thrust button on with a big LEFT Thrust.   I was a little later heading out at 11:00 AM to the Cricket Wicket  in Jackson Park ( I knew the Auxiliary Police start their rounds at noon ).    The weather was  59 deg F, winds from the Northeast at 6 mph gusting to 9 mph, and 63 % humidity.   I had just put in a new prop shaft, after the seventh flight on June 3, with the huge climbing and stalling porpoising, that drove it into the ground with lots of steam after a stall, and BENT THE PROP SHAFT, right behind the prop - I did not notice it til I got home.  That is why the plane went nowhere on the 8th flight, and its flight was really loud "rattling" - all this finally caused me to glue in that black plastic thrust bearing also.   I put in the short  14"  3/16"  four strands motor, because I now had that right thrust shim behind the nose block, and I wanted it to stay on,  and I took off some nose weight and right wing tip weight
     I got six flights in and another new record of 34 seconds ( previous record is  30  sec. ), on the sixth flight on 555 turns with a big wide high, two and one half circle left hand flight, using up the whole Cricket Wicket like never before, and going dangerously high, and dangerously close to the trees.   I also had a  27 sec  flight on the third flight, on 495 winds, and I knew things were looking promising then.
     It was getting more windy and gusty - it was time to scram - the Auxiliary Police were soon coming, and I did not want to get caught, so we skidaddled it out of there - packed up at  11:45  AM  and home at  11:55 AM, the weather now was  61 deg F, winds 8 mph from the Northwest gusting to 12 mph, and 59 % humidity.
     New flight record for the Speedster of  34 seconds  on the  14"  motor, and I did not even try the  18",  20 1/2", and   22"   motors yet, and have not resorted to lubing the motors yet,  but I will once I find the right size motor to use.  I did not even get a pic of the long flight - I was to mesmerized just watching and timing it.   These were the highest elevation flights I have seen the Speedster fly yet.
     FREE FLIGHT FOREVER !!

Richard,
Lubing rubber is not a resort measure, it is a MUST-DO. Your rubber will last way longer, and take more turns into the bargain.
The only down side is that it may splatter on the tissue from the inside, if you apply a little too much.
A broken motor will do far more damage though, because they always break at high turns, when the energy is greatest.

I hope this doesn't sound like a lecture, but you MUST LUBE YOUR RUBBER MOTORS.

Careful you don't lose the model the first time you fly it with a lubed motor. You might find it goes a lot higher and longer on a similar number of winds.

I agree; in my book, big steady circles and 30 seconds plus is a nice flight (lubed or not!) and would be plenty long enough for me. It's a very appealing model all round.

I believe I have an Eaglet in my cellar, whether in flying condition or not I will have to check. I also have most of a Gypsy (or is it Gipsy). I am seriously considering building the Ace, having watched the video on youtube by domoremath. I think I have a Senator kit too, but perhaps it's just the box. A friend who departed the hobby donated a lot of his stuff to me and I think the Senator box just contained sheets of wood. I had to go and buy some 1/16th yesterday because although I have a huge amount of balsa almost all it is in 3/32 or 1/8 thickness or even thicker, good for making improvised building boards or jigs..

Post by: LASTWOODSMAN on June 07, 2018, 12:29:30 PM
     Well, I did take the advise and tackled the lubrication of four big 4 strand motors of  3/16"  rubber  -  22",  20.5",  18",  14"  -  prop hook to rear motor peg is  15"  -   for the  30" Rearwin Speedster.  I was up til  1:00  AM doing this.  I had to get out the round head nails, digital calipers, drill bits and drill, and drill right sized holes in the hardwood block on the building table, and drill holes into the wooden armrest of my chair, for the nails.  I needed a lot of books to hold the chair down.    :-\
     I lubed up these motors as per Don Ross' book "Rubber Powered Model Airplanes"  -  stretch the motor to  3 X   its length and  lube for 2 minutes,  rest the motor for  10 - 15  minutes,   then stretch the motor  to  4 X   to  5X   its length, for  4  minutes.
      The  22"  and   20.5"  motors went OK, but when I stretched out the  18"  motor for lubing, I discovered a nick half way through one of the four strands.   ???    Thanks for the motivational "kick in the rear end" guys to get all this done.   Also the  14"  motor was starting to slightly fray on the edges of the motor all over the place.   :o    So I had to make new  14"  and  18"  motors with Crocket hooks from George Bredehoft at Volare.  I used "Handy Twine"  cotton  string  (kite flying string when we were kids)  to tie up the rubber motor ends, at the rear peg loop, and Crocket Hook.
       Now I can rest easy, knowing I have four good, unused, broken in and lubed motors ready to go for the next flying day when the weather cooperates.   ;)

Lastwoodsman, you are certainly getting full value from that Rearwin. I plan to build the Earl Stahl version one of these days and have almost built the 16 inch Comet one but broke some bits off the tail while handling it. I t will be resuscitated one day soon i expect. There are some great videos of a real preserved one on youtube with nice detail of exhaust pipes and the like not shown on the plan. I have seen the Earl Stahl one do moe than a minute back in the dear dead days (almost) beyond recall.

>the pig-ugly Senator

Jack, I guess the  old adage applies here .... that beauty is in the eye of the beholder.

I don't find the Senator to be ugly at all -- a practical flying machine that more than fulfills it's purpose.   Even if I did perceive it to be so then I'd far prefer an ugly airplane that would provide satisfying  2:00 to 2:30 flights to a pretty one that did 60 seconds.

Each to their own !     ;D ;D

I'd be interested to hear from anyone following this tedious routine as to whether it actually makes any positive and noticeable difference to the performance and life of a rubber motor.

My practice (assuming a fully trimmed model) is to initially install a new lubed motor, stretch it out said 4-5 times (maybe more), wind to full torque  ..  and fly.  Motor is then inspected and   returned to its baggie in the cooler to rest until next outing; another motor then installed for next flight ... and so on.

Next time out - same routine..  Motors usually last some four/five hard winds before being discarded.  Blast tube always used...   :)

REARWIN "SPEEDSTER"    30"    FLIGHT AND CRASH June 7 2018

     Well,  you guys are probably all right in all you have said regarding the demise of my  30" Rearwin Speedster, on what I should do now, fix it, or build a new kit, etc.   I am still quite puzzled about, and still trying to figure out, what went wrong with that last fourth flight.    ???    I am getting a new printer sacanner photocopier next week, and maybe a keychain camera, and join facebook,  to properly record a flight video, and be able to post it, maybe.    And I must start bringing a ribbon streamer with me, to the field, to check the wind.
      I really liked flying that 30"  (Ray Rearwin) Speedster, high wing sports plane balsa model.   Feels like I just lost my best friend.  I can just imagine what those  Out Of Site,  OOS flights feel like on their "Bon Voyage" flight , to their owners who will never see them again ...    There was a stately and majestic quality,  to the  'Jumbo'  Speedster, powering and flying around, throughout the Cricket grounds.  She was very photogenic with the sunlight shining through the translucent tissue covering.   And she really had a magnitude of sweeping force, when swooping around, in those big fast circles, in the air  above the wicket.
      I liked it the best of the only three "scale looking" models that I have ever flown "successfully",   the 62 sec parasol wing   17 1/2"  AIRCAMPER (Dumas),   and the 57 sec high wing cabin plane   22"    CABINAIRE (Sig),    and the 34 sec high wing  'Golden Age'  sport plane    30"  Rearwin SPEEDSTER (Dumas).  
     Sometimes in your desperation, you try going all out  on your number of winds, in order to get that record flight, with an untrimmed plane, variable wind, and trees!    :'(
     Yes Crabby !!     "Now you're really living !"    You may be perfectly right.  The thrill of victory and the agony of defeat.   One cannot really enjoy true happiness and elation   ;D   to the fullest,  unless one has experienced the true sadness of despair   :-[   and defeat.   The wider the spectrum, the more intense are the emotions, and the more intense the serotonin and endorphine adrenalin rush.
     In the meantime, I must perform exploratory dissection surgery on the Speedster.    ::)  The prop is still crushed and embedded     :o    into the clay, on the smashed in, and smashed out sideways, cowl  (like someone going to the hospital, accidentally being impaled with some instrument awaiting surgery to remove it).   And everything is locked and solid tight, as the rubber motor is still as tightly wound, as when it hit that tree trunk, with about 160 turns left on it.

     I must now catch up on 3 logs I have yet to put into my Flight Book in 'Your Birds In Flight.'
One - June 3, 2018   -  8 flights,    perfect landing
Two - June 6, 2108   -  6 flights     record 34  sec,  
Three  June 7 2018   -  4 flights.    big CRASH

     Rearwin SPEEDSTER  30"  Well here are the results of the "dissection" of the smashed up Speedster,  from the   June 7  2018,   crash into one of the tree trunk's main, upward bending, trunk-sized, limbs.   The removable nose block itself, along with the right thrust, unstained, bare balsa shim, miraculously, are both undamaged.   ;D    The prop wire is bent right at the back of the hub.   The right wing strut seems to have broken off clean   8)   at the fuse on the bottom "V" end of the strut, and the upper "V" end of the strut has both tips securely still glued to the wing, and should have the correct dihedral already in place.   The fuse front former is smashed in at the sides, but has the top and bottom quarters of the front former intact.   I plan to just glue another  1/16"  thick former, to what is left of the front former, then glue in a few stringers, and infill plank the rest.  
     Yes, you are right David.   I was playing it too close to the circle boundary, of large full grown trees, and their thick trunks, that surround the Cricket grounds   and Wicket, exactly on the white painted Cricket Field  perimeter line.   On the crash day June 7, I was getting high flights and on two out of the three successful flights, and they both finished off, landing and  flying, into and past, the tree trunk line, the same on the day before on June 6  where my record  34 sec flight finished off flying past tree trunks and making me PANIC.   I should have flown her in tighter circles, and should have used much lower winds of the motor to start with.  But I still swear that it was a sudden, change of direction, gust of  wind, that blew that plane too far behind me, and into the tree line on its second circle, crashing it.   :(  
     I am looking forward to see if it will fly again after I glue that wing back on.   I will now just keep this "stitched up battling broad" as a Utility aircraft for flight trimming experimentation, and therapy flights ... and of course, also for pursuing that ever elusive, record breaking flight ...
     I also agree that this plane has surely given me my monies worth - I checked my log just to see how many flights I had with it -   in the last two months since April 8 2018,  I have had 98 flights this spring with the Speedster, oh,  and of course smashups too.   :D ;D :D ???

I got this drill bit set a couple of weeks ago, from Boyes, which is chain of cheap we-sell-everything shops we get in these parts. There are 20 drill bits, ranging from 0.3 to 1.6mm diameter. The only thing is, because they are so small, the diameters are written beside each slot in the case rather than on each drill. So it is most important to replace each one back in its correct place every time you use it.

The slide-open lid was very stiff, but after a lot of wrenching it suddenly came free, helpfully sending drill bits flying to every corner of my very messy workroom. So far I have recovered 16 of the twenty, which is more than I expected.
(As to getting them all back in their correct slots: forget it.)

Pete, that's nearly identical to a set I've got - You have to bend the little handle or hanger on top of the coloured tray down a bit, then the transparent top cover should slide back. It's difficult to bend it down with sufficient force whilst trying to slide the top with yer other hand. Dave's just posted - yeah, use a screwdriver to pop the 'catch' down.

Rearwin SPEEDSTER  30"      NOSE AND WING REPAIR

     Well, I said I was going to do it ...   I made some progress on the Speedster's broken wing and the smashed up nose today.   I built a couple of  1/16" stringer troughs for wing spar "doublers" - just slide them into place, and glue them up to broken stringers.     Glued in a few small broken pieces of the nose front former.   I butt end  glued two , two inch long leading edge pieces together - the shear slivers fit into one another.   Glued a  2" piece of trailing edge to the broken wing root.  Made a new add on,  0 .080" thick front former plate, to be glued over what is left of the real one.  And cut out two   "R2"  ribs for wing root attachment.

Rearwin SPEEDSTER  30"      NOSE AND WING REPAIR

     By the way, on this model, I glued the tissue covering to every stringer and every former and every rib, both top and bottom.   All the little tissue covering tears can be easily cut out now, and a new piece of tissue glued on and shrunk.
     I am just trying to get everything glued up a close as possible.  I really should have checked the crash site really well for all the missing pieces.
     I glued up the right front side of the fuse former and stringers.  The noseblock fits in OK.   The butt end glued,  3 1/2"  length, of the two shear broken, Leading Edge pieces, at the root of the wing, is now dry and straight.  This leading edge piece, also has the front center section rib tip boken off and still stuck to the leading edge  -  just to complicate things ...   And I glued on that broken off,  trailing edge of the root of the wing, that still has a triangular piece of tan color tissue covering stuck to it, and a big sliver of the rear center section rib,    just to complicate things ...   is also stuck to it,  for support, for now ...

PIC #1    9475      Gluing up the right wing root Trailing Edge - this has a big sliver piece of the center section rib that broke off and a big thick gusset.

PIC #2     9476     Three large   1/16"  gussets were added to the trailing edge.

PIC #3     9478     Broken 3" Leading Edge from wing root is glued up between the "Saran Wrapped"  balsa alignment planks on top of the big balsa block.

PIC #4     9479     Over view shot

PIC #5     9481     Other open side of fuse nose.  I will glue on the new bare white balsa former, first.  Then a stringer and infill planking.

PIC #6     9484     Fuse nose framework is coming along.

It has all come out nice and flat so far.  But it is all very tricky.

Reading a vernier caliper can be hard on old eyes. The dial caliper is better, but I prefer the electronic version. Occasionally they come on half-price sales.
see: http://www.canadiantire.ca/en//pdp/mastercraft-digital-caliper-0586800p.html (http://www.canadiantire.ca/en//pdp/mastercraft-digital-caliper-0586800p.html)

At work I moved from a vernier-scaled to a dial caliper (accurate to 0.01mm) precisely because I could eyeball it without having to put my reading-glasses on or have to engage what's left of my brain!  The model I suggested to Pete is my other one; it's only accurate to 0.1mm (actually 0.05 if you halve between graduations) which I keep at the machine end of my workshop (when I'm not filching it for use at the modelling table at home) because it is made of tough nylon and is less complaining of being dropped.  I find digital ones have a habit of oscillating around readouts, especially if accurate to two decimal places, and going flat if one forgets to switch the power off!

I have bought these for work to include with the equipment, they are ok and as Jon says are reasonably accurate.

https://uk.rs-online.com/web/p/calipers/8412537/

As for the digital ones, the cheap ones are quite poor IMHO, it’s one of those occasions that you get what you pay for. For me the only ones in the game are the Mitutoyo ones, they are £50-60 a set, but unlike the cheap ones the batteries last for years, even if you leave it switched on, and the display is as steady as you hold them.  I had a set for about 20 years until they got stolen, In that time I replaced the battery on only 5-6 times.  The new ones to replace them are absolute, which means they don’t loose the zero when you switch them off...

     I got the front extra nose former glued to the "what's left" of the 30" Rearwin Speedster's original front former.   Double  ( more like quadruple ) white gluing, a  lot of preparation and sanding, and over night it dried CROOKED,  pulling the top of the former over to port left side.   EGADS !!   Have to live with it.  Yes, I had to get out a long round sanding stick, and sand in the upper port formers on the inside of the fuse - the rubber motor goes right down the center of the top circle of the oval opening.  All prep sanded and now ready for infill planking on the nose.

Pic #1      9489     Nose block is wrapped with "saran wrap"
Pic #2      9490     The former plate is glued in place and held in with the nose block. 
Pic #3      9492     I tried masking tape to hold that noseblock pressing inwards.

     Mandrake and Bloodroot receive orders to do the repair themselves.  Being half machine,  they have been programmed with every bit of knowledge throughout man's history.   They are powerful Cyborgs, and had no trouble at all wielding around that big saw.
     The wing leading edge root is glued back onto the wing, and an extra temporary bracing plank is also glued between the LE and TE.

Bill,

The T-28 cowl has clamshell panels to facilitate maintenance - I broke the covering up the same way and used the panel lines to hide the joints.  Before covering I brushed balsa fillercoat over the cowl and sanded it smooth (helps hide the woodwork and makes it easier to slide the tissue around).  All covering was done wet with glue stick and 50/50 alcohol-water mix.  The orange tissue was chalked with neon orange to make it brighter and a bit more opaque.  Here's the sequence:

1. Covered the inside of the carb and oil cooler air scoops, wrapping the tissue around the inside of the cowl opening.

2. Marked the location of the panel lines on either side of the two scoops and the rear edge of the cowl with modeling tape.  Covered the scoop areas, trimmed the tissue to the tape lines, then removed the tape.

3. Marked the location of the right side cowl access panel with tape, then covered the bottom area between the tape and the oil cooler scoop.  Trimmed the tissue to the tape on the right side, then used a #10 curved blade to trim the overlap with the oil cooler scoop, trying to keep the overlap to about .5mm.

4. Marked the rough location of the antiglare panel with tape, then covered and trimmed the cowl sides and removed the tape.

5. Marked the final location of the antiglare panel with tape, then used a white Prismacolor pencil to tone down the orange tissue where the black would overlap (I had about 3-4mm overlap at these joints).

6. Used scrap tissue to make a template for the antiglare panel, then cut that from black esaki and applied it wet using the tape lines as a guide.  Had to do a bit of trimming to clean up the front edge.

7. Made the exhaust shields from silver esaki and put a 3mm strip of black esaki inside the cowl to mimic the gap between the cylinders and the inside cowl lip.

8. Using strips of index card as a straightedge, drew panel lines over the overlaps using a black Prismacolor pencil.  If you look closely you can see the tissue overlaps, but the panel lines draws the eye away from the overlaps and hides them pretty well

Hope this makes sense...

Cheers,

Mike

Roman, the white is chalked.  I have not yet doped the fuselage - I find it easier to get consistent panel lines on undoped tissue.  Still have some lines and access panels to draw on before doping.

AIR CAMPER      17 1/2"        FRI JUNE 15 2018

     There were no good flying times in the last 8 days.  ???  Finally got one now -  ::)  -   grabbed the  17 1/2"  Air Camper,  10:25 AM,  72 deg F (feels like 75),   winds from NE 9 mph,  gusting to 14 mph,  50 % humidity.   The park grass and lawns have dried out and started to turn that dormant brownish yellow color,  and the grass is cut too short, and the ground is too hard - can't even push in a twisted metal tent peg by hand any more.   And now another week of sun and heat here in the Windsor/Detroit area, and too windy to fly.
     By the way, the dimensions of my  slightly oval flying field, the Cricket Grounds' outer white circle, as measured by my Golfer's stride, are   113 YARDS   X   132 YARDS,  or,   339  FEET   X   396  FEET.    ( real dimensions are   130 Yards   X   140 Yards  ??)

SEVEN FLIGHTS with the AIR CAMPER  this morning ...  best flight 35 sec

STARTING MOTOR

3/32",   FOUR STRAND,  12"  long   rubber motor ( prop hook to rear peg is 12" ).

Flights
#1     600  winds,  14 sec,   1/2 circle left, flew low and even the whole way.
#2     755 winds,  24 sec,    1  1/2   circles,  slow, soft, launched from NE corner.
#3     675 winds,  35 sec,     1  1/2  circles,  going straight on last westward leg.
#4     795 winds,  20  sec,    1 1/4  circles,  flat   LOW  flight,  descending,  ran out of altitude with winds left on the motor.

CHANGE MOTOR TO
3/16",  TWO STRAND,   9" long motor

#5      600  winds, only lasted 9 seconds, as it quickly started a quick tight circle left and landing just behind the stooge and me, in the shade, and after tumbling lightly off of the spruce tree evergreen boughs.    
Now added weight to the right outer wingtip, to widen the circles out a bit more.
#6     600 winds,  6 sec,   1/2  circles,  does not seem to have enough power - cannot hold level flight

CHANGE MOTOR TO
3/16",  TWO STRANDS,   14"  long motor

#7     825 winds,  right away it shot up straight up, and being bounced around by the wind violently.   It then came twisting down, like the twists on a drill bit, in a "powered", tight, incipient spin, straight down for 5 seconds, about 8 perfect little tight spins, (with no successful attempts by the little Gypsy to pull out and recover), straight down that downspout.  It seemed like it was driven down a wind vortex, micro mini tornado, dust devil (with out the dust), also like those ones that blow the leaves in a spinning,  spiraling,  circle.  I never saw one like this before ...  I think that the torque of this  3/32"  motor was too much for the plane causing sharp left banking turning dives (?).
        Time for us to go, as the grass mower operator was "moving me off the field", and probably laughing his head off at this last flight.
       Got home at noon and the weather was 73 (77) deg F,   winds from NE  4 mph gusting to 7 mph,  47% humidity.
      Now at home, I notice that I had lost the right wingtip clay weight from the previous landing.   Hmmmmmmm ....   The more I fly, the more I get lost in the mysterious world of aero-dynamics.   And now I can't stop reading about DYNAMIC SOARING ...

Pics     9520   9521   9522   9525   9524
Pic #5 shows the view towards the North, with the wind blowing from the North towards me fom the replica Spit and Hurri, through the big gap of the trees in the middle north perimeter of the Cricket Grounds, as evidenced by the fuchsia colored flagging tape, blowing towards me, held by my hand.

Didn't get any really good pics, but she was in the air ...

Richard , are you resting the motors between flights? You would need 2 motors at least of your best length and size. I think this will give you more consistent flights and possibly help with your trimming.

SPEEDSTER 30 "     NOSE AND WING REPAIR

     There has been lots of sanding and little things to get ready.   Mandrake and Bloodroot work tirlessly ...   :P

Pic #1     9531      Major nose reconstruction,  the windshield was removed, smaller infill gaps are glued up with scrap balsa,   a small front sliver piece of wing center section LE,   is white glued back into place,  bare balsa to bare balsa.

Pic #2     9533       Here Bloodroot works on cutting out the 1/16" square notches on top of the front nose former, for the front nose stringers and infill planks.  

Pic #3     9535       Something behind Bloodroot catches Mandrake's robotic cloned eyes ...

Pic #4      9538      Now, when test fitting the wing to the fuse, the LE of the wing with the rib part, fits well right into its  spot.  

Pic #5     9539       And the wing TE, "Rear End of Rib" long thick sliver, also matches its spot.  And best of all,  the wing strut attachment at the fuse seems to fit well also.   :)   ::)

Pic #6     9540      Mandrake and Bloodroot look  over their progress.   8)  8)

Cyborg Super Soldiers,  Mandrake and Bloodroot,  have been hard at work cutting and shaping infill planks all day.

Pic #1     9544     Stringers have been glued in to the top of the nose.

Pic #5     9549     Mandrake and Bloodroot step back and examine their work.

Pic #6      9566     The nose is still bent to the left port side.    ???    This will add more left turn "Yaw"  ( I think )  - it is bent about four degrees.

I took John's advise, and got Mandrake and Bloodroot, to glue a right thrust shim also, onto the front of the fuse.

Pic #1     9567     Making up thin wedge balsa shims for the crooked nose.  The thin wedge shape was sanded first.

Pic #2     9571     The infill planking on the nose is now sanded, and the shims are cut out and fitted.

Pic #3     9573     Other side of nose.

Pic #4     9576     Here is angled balsa shim wedge, for right starboard thrust, between the front fuse former, and the saran plastic wrapped,  removable nose block.

Pic #5     9575     Final test fit of the right thrust shim, shows that the prop shaft is straight and parallel with the fuse center datum, even though it is moved over a little bit.

Pic #6     9577     Now double white glued and ready to dry.

Lurker Industries are currently assisting, to the fullest extent possible, both the Ministry of Works and The Board of Trade in their joint enquiry into workplace safety at The Lurker Industries Aviation Co. Ltd after an employee was injured in a serious industrial accident.  Concern has been expressed by the Board of Directors that such incidents will seriously affect the schedule of planned works.

Mr. Kite, a representative of the Union of Wood Trimmers, Fettlers, Tinkerers and Allied Trades (Southern Region), is reported as saying, "What a diabolical bleedin' liberty.  No guards on the machinery and they stop you half a day's wages when you go and see the M.O."  He is also reported as having said, "I've a good mind to call an all out strike, show these capitalist running dogs that they can't abuse the working man and get away with it."

Or... when putting a straight edge on balsa sheet prior to cutting strip don't be an utter BF and leave your finger in the path of the scalpel blade.  Happy half hour at the local minor injuries unit last night because the blasted thing wouldn't stop bleeding and all building works at a standstill for a day or three.

How I wish I'd thought of CA, might have saved me a 30 mile round trip, but the problem was it wouldn't stop bleeding even with continued pressure. Never mind though a nice nurse made it all better and gave me a lollipop*. 

*No I didn't really get a lollipop (cries of shame) but I did get a (friendly) grilling about aeromodelling 'cos the nurse has a couple of young lads and she was enquiring on their behalf.

I have started working on making up rubber power plans for semi-scale WWII fighter planes of the Battle of Britain era according to P-30 rules, very closely along the lines of the Sun Dog Spitfire P-30. I have sorta-committed myself here to the effort this past week in response to a search thread for a P-30 Me-109, which does not exist to the best of my knowledge.

Chosen were three designs from the period, the Hawker Hurricane, the Focke-Wulf Me-109, and the Junkers Ju-87D. Like the Spit, landing gears will be absent, which will make for some complication when doing the Ju-87D, it's gonna need some good performance in order to offset any flight penalty inherent with incorporating those spats. Also like the Spit, the semi-profile layout, the cracked rib wing construction, and many of the other neato design tricks will be copied in the truest form of flattery/gratitude.

My personal construction preference involves a cracked wing rib with turbulator spars, geodetic sorta-Rees configuration with laminated surface tips. I slice my own thin strips for lamination, often reducing the strip thickness to less than 1/32". I utterly detest notched wing ribs and fuselage formers, and would build my own designs purely from strip wood if I could manage that. I also put a lot of thought into especially reducing weight aft of the balance since that usually translates into nose ballast, which I think is a pointless weight penalty.

Somewhere in all of this, the designs will need to be built and flown in order to confirm structural integrity, and to refine design suitability and allow for any needed trimming. I'm leaning toward doing it all from 3/32' and 1/16" square strip wood; with minimal sheet stock where absolutely needed, like in the nose, center section, and wing saddle ares, and maybe etc.

None of this will happen in a week or so; so be prepared for a bit of gestation time. Once they fly well enough to avoid my own embarrassment, I'll send something to Ratz for rendering as a .pdf, and uploading into the plan gallery

I began by perusing the plan Gallery for semi-scale plans of the aircraft in question, printing them out along with multiple copies of the P-30 Spit plan, as well as the full page Profile Pubs color plates of the early Spit, Me-109, Ju-87D, and Hawker Hurricane from about the right period. Not sure how I'll incorporate these last items, but I figure that good documentation is never a detriment.

I will be doing the initial design work by hand, producing more manageable reduced size drawings on 8 1/2" x 14" legal paper. When finalized, I'll redraw them and ink them as Full P-30 size plans.

The effort may constitute the emergence of a new category, which I'm calling P-30 Lo-Cal Semi-Scale. It will initially conform to the request for the Me-109 design to complement the Sun Dog P-30 design, with initial special emphasis on Battle of Britain types, to which I am also adding another British entry and another German entry. Because of the BoB emphasis Planes like the P-51 and FW-190 are currently absent, but maybe could emerge following a successful BoB contest as mentioned by the search poster.

I am a firm believer in absolute minimalist rules, no nitpicking or potential for same. My starting requirements suggestion would be that the plane must be representational of a war bird type conforming to P-30 specs and only P-30 specs, be of a type that conforms to the genre/conflict named in the contest title, and be consensus recognizable as the aircraft type as stated by the flyer in their entry. More than that, I'd advise against.

This is all projection based on a bit of a winger, sticking my chin out somewhat, trying to stretch my own personal envelope. I intend to make this work, no buts.

Wish me good fortune.

SPEEDSTER  30"     Repair

    My Printer is dead, so I had to trace the plans by hand ( a most enjoyable old fashioned way to do it), for Dihedral Jigs, and to make a Jig setup to mount the fuse, for when I attempt to glue the wing on.  The nose is now almost completely done.

Pic #1     9618     This is the plan I drew up of how to try to reassemble the wing, with matching dihedral.

Pic #2     9625      There was only one front view on the plan, with only one wing on the fuse.  I flipped the partially rolled plan over, and green masking taped it to the window, and traced out the other side wing ( negative Ys).

Pic #3     9629     I was able to save the decals after the crash,  and the RH side decals are now glued back into position, using 5 min Epoxy.

SPEEDSTER  30"     Repair

WING AND FUSE         FIXTURE JIGS & TEMPLATES

     I knew I had to make, but was dreading figuring out how to make it, had to make a jig fixture for the fuse and the wing to glue the wing back on with.  The sides of the Speedster fuse are not perpendicular, but slightly angled.   I had to make a saddle fixture jig to locate the bottom half of formers 2, 6, 8, and 10.

Pic #1     9638     I drew up the bottom half of formers 2, 6, 8, and 10, by tracing the cutouts of the laser cut kit supplied balsa parts sheets.

Pic #2     9641     Here are my two front view drawings.

Pic #3     9644     Here are four plates cut out from Elmer's ROSS Craft Whtie Foam Board  -   20"   X 30"    X   3/16"   https://www.flitetest.com/articles/ross-foam-board -  for  $1.50  at Dollarama.

pic #4     9646     The top paper templates are cut out.

Pic #5     9651     The top paper templates are now scotch taped to the top white foam board plates.

Pic #6     9661      Mandrake and Bloodroot "manhandle" the  "two man" Coping Saw,  and get busy cutting out those plate fuse saddle templates.   Here they are, adjusting the blade angle 90 degrees, at both ends of the saw blade.

You know Richard your posts are continually entertaining and informative - that jig thing is a good idea - apart from setting the wing it clearly has many other uses - I find I never have enough pair of hands and that idea (obvious now I see it of course) will help a lot. Your Special Forces chaps are a nice touch.  Did they use a saw pit for the cutting!

DIHEDRAL JIGS FOR THE WINGS AND RIGHT WING TEST FIT

Thanks David  - I hope   :P   it's entertaining ...  This Fixture Jig really does work well.  I have to put in a new one piece side windows and wind screen, and I need the plane to be solid for that installation.  "Saw Pit"?   They must have used one ... ?

Thanks Crabby - I did come up with the color palette - I had seen the basic pattern before - then looked  over all my many colors of tissue, and chose black, dark brown, brown, and tan.  The best part is, it turned out to match the long side fuse, peel n stick decals (Dumas),  that are a red color with thin black striping.   And the earth tone wood staining is my idea too, but I am sure many have gone before me ....

thanks too John.

Pic #1     9680     The  7 degree  Dihedral Jig is fitted under the left wing.

Pic #2     9683     The broken right wing is  test fitted, and it fits right in to the location gluing points of the fuse center section wing root.

Pic #3     9683 snip 2   Even the wing strut sits into its fuse locating hole, of mostly dried  5 min Epoxy,  and a little bit of bare balsa.

Pic #4     9685     There are two nice Dihedral Jigs for the right wing now, and I cut out a portion of the front Jig, for the wheels,  and now the model can go in and out easily.

Pic #5     9687     Test fit of all wings and Jigs is good !!  I am pretty excited that the fit is this close.   ;D

NEW WINDSCREEN,  WING PANEL TISSUE, SANDING GUSSETS

Mandrake and  Bloodroot have decided to do everything they can, repair wise, while the wing is still off of the fuse ...

Pic #1     9695     Mandrake and Bloodroot cut out a new one piece Windshield and Side Windows Pattern, out of  0.005"  thick clear plastic.

Pic #2     9703     M and B cut out a wing panel from tan tissue.

Pic #4     9709     Bloodroot and Mandrake mix in a little Ju Jitsu to stay in shape.

Pic #5     9714     Bloodroot examines the tissue glued to the leading edge, and smooths out  - (burnishes ) - smooths out any wet wrinkles with his moist finger tip.   Mandrake paints a very thin mixture of white glue/water  20%/80%   V/V ,  on top of the freshly placed, tan tissue panel.   All surfaces are glued - even the bottom of the bottom spar.
    
Pic #6     9713     Bloodroot and Mandrake shake hands at the end of the day,  after some great teamwork in the Woodshop Hangar.

Fitted Control wire pulleys to my DH2 model. Also  inserted DLG style  hinge springs to the upper ailerons.  They work "beyond expectations".
Although Still dithering as to whether to use linked cables in lieu of the spring loading though.

Lurk I believe that repair would be good for a light tow or light bungee (ALA Peterborough)...

And indeed it is.  Thanks to all who suggested bungee/high-start launching post wing rebuild for the Swallow; works a treat.   Had a very pleasant morning at the Oxford Club's FF rally on Port Meadow today and, after some modifications to the hook suggested by David H. who was up from Chichester, got three (by my lights) very good bungee launched flights out it, a couple in the 30s+ region and one somewhere around about a minute in some really rather awkward wind conditions. 

Also nice to meet Pete Fardell who was there with his Petrel.

MANDRAKE AND BLOODROOT Detailing

     Well,  I got side-tracked for the last four days.  Sometimes you just feel like painting.   Mandrake and Bloodroot, Cyber Super Soldiers, and star performers as aviation mechanical engineers, in the rebuild of my  30"  Rearwin Speedster, got cleaned up and painted (long overdue) and detailed.  From plastic flash and poor paint, on two well defined soldier figures,  now (yes after 4 days of painting LOL) comes two very realistic looking Cyborg Super Soldiers, heavily armed, and complete with full battle dress, including :    binoculars, large knife, removable backpack, standard issue AR 15  or  Bazooka, plus an extra smaller knife,  and a small holstered handgun,  strapped around each leg calf, gun belts full of ammo, grenades etc.
       They are almost  7 3/4"  tall, and I think, are only single ball jointed - very short movement in the limbs.  ( A Scale of  1:12  needs a human figure that is 6" tall.   I am still looking for that poseable, double ball jointed, full figure male human, for a pilot for my Curtiss Pusher ).    
      There really is a lot of detail in these plastic molds,  for these well thought out and researched,   little soldier figures.  I think I paid  $3  for each of these toy Figures at a Dollar store or Toy store.
     Time to put them back to work in the Hangar, putting the wing back on the Speedster.

Today was not really an airplane day or even an aeroplane day but even so I have managed to do a bit of sanding on the current most favoured project, a Comet P51A with four cannon armament - I haven't got to the cannons yet,  or the shell guns as they are referred to in Aircraft of the Fighting Powers, which has a pretty good three view and description, with some probably deliberately misleading information about a variant with Packard built Merlin engine. The Comet plan was one of those that had cardboard formers but naturally I am using balsa. I wonder if cereal packet cardboard would be in the right 'forties spirit - the plan is copyright 1943, when I was eight years old and unaware of the existence of Mustangs, four-legged or otherwise. I discovered last night that I have also at some point downloaded a Comet Industries 3-view which looks pretty good, and have now ordered another Mustang book to add to my considerable collection. Meanwhile I have set about stripping an own design P51A that I built earlier to 1/24th scale, I think in 1990 or thereabouts, with a view to seeing if I can make it fly better than it did the first time. I shall be moving the rear peg forward to just behind the wing instead of where it was before, just under the tail. I might opt for a simple USAAF scheme in olive green and light blue (or perhaps gray) tissue for this one, but the 24 inch one is to have an RAF scheme if I can get my tissue printing act together. I might even have to buy a plastic kit as inspiration but Im trying to resist.

Converting wood from a Guillows #26 kit Eagle glider to Ray Kierna's Kayaba KA-1 Autogyro. I boiled the wing and pinned it down to dry to take out the dihedral. I stripped wood from the fuselage for the square stock and used the flat stock for the rotors and formers. Fuselage weighs 0.75 g, rotors weigh 1.3 g.
I converted one kit to a Cat-launch glider and another to a rubber-powered plane.

Pic #1     9808     Mandrake and Bloodroot set to work sizing and fitting the balsa  "CHANNELS"  (troughs)  that will hold the broken spar stubs -  the stubs on the root rib at the fuse center section, to the spar stubs at the first rib on the wing.  ( The stubs stick out far enough, from the rib, in order to glue channels to them. )    The channels will be filled with spar balsa after the channels are glued.

Pic #2     9811     The first channel is done and filled with  1/16"  X  1/8"  spar balsa.   Mandrake and Bloodroot here are working on fitting the second channel.  These spars are  1/16" square balsa, that will fit side by side in the channel, filling it up.

Pic #3     9813     M and B  examine their work on the second channel, which is now glued in place and filled with  1/16" square balsa spar material.  The two flat files, (with blue handles), hold the channels in position to dry, with upward pressure from the weight of the sanding bock,  and the leading edge acting as a fulcrum.   Two more channels to go  -  one more  1/16" channel on the top of the wing,   and one more  1/8"  square channel on the bottom of the wing.

Rearwin SPEEDSTER 30"  Repair

WING ATTACHMENT   -    FOUR REINFORCEMENT CHANNELS and TISSUE PANEL,  DECAL,   STRUT WIRE SUPPORTS

     The last two  -  1/64"  support wires are glued into the right wing strut attach point on the fuse.

Pic #1     9828     After the new tissue panel on top has dried,  Mandrake and Bloodroot size up the rough-cut,    "N"  decal,  that was salvaged from the crash.

Pic #2     9837     The top two black tissue panels have really difficult contours, so Mandrake and Bloodroot took measurements and eventually cut out two exact size paper templates for the tissue shape.

Pic #3     9836     M and B prepare further.  They cut out the tan tissue panel ahead of time to apply later, after the new one piece  windshield/window/skylight  fitting.

Pic #4     9832     M and B use their Cyborg Robot strength to lift the Speedster with its newly attached wing, out of the jig, that is has been tied down to with elastics, just like Gulliver. 

Pic #5     9838     The decal has now been trimmed and ready for gluing, and the very last  4rth  channel (that goes on the bottom wing side),  sits on top of the decal.   The top three channels are complete and sanded -   I think it is a pretty strong fix, as I compared wing "twisting" on both wings ...

Pic #6     9840      DIHEDRAL AND CROOKED NOSE SHOT Straight on view  -  the dihedral seems to be pretty close, and you can see the crooked nose pointing to the left (port) a little bit - will the propwash hit that nose and force the plane to the left ??   (The same as adding left turn rudder ?)  The prop wire is parallel to the fuse datum line.

Pic #2     9884     Closeup of the underside of the four channels.     

Pic #3     9870      Shot down the wings to check the straightness.

Pic #4     9866     Mandrake and Bloodroot lay down and stretch tight  the tan color tissue panel for the top of the wing.

Pic #5     9886     M and B cut out the top cabin roof, black tissue panels, from drawn up, and cut to size, white paper templates,  that were masking taped over black tissue and a cutting mat. 

Pic #6     9891     Here  M and B are making new panels, as the first two ended up with bad  ??? ??? ???  center line wrinkles (ie - don't press on them until the glue is dry).

Rearwin SPEEDSTER 30" Repair

WING ATTACHMENT   -    LAST BOTTOM OF WING TISSUE PANEL and  FUSE TISSUE PANELS  and  "N" DECAL

     The black tissue roof panels have been glued in, and several small patches of tissue are glued over the fuse holes.   Been gradually working on the windscreen on the side.

Pic #1     9894     Mandrake and Bloodroot are gluing the decal call letter "N"  using  UHU glue stick.

Pic #2     9896     M & B are stretching tight, the last glued tissue panel on the right wing root bottom.

Pic #3     9900     At the end of the day,  M and B  are   ;D  overjoyed and  ;D celebrating too soon  -  they forget that the hard part is yet to come -  the one piece "Windshield/Windows/Sun Roof"  windscreen   >:(    must be fitted and glued in, before shoving a rubber motor down the throat of the fuse.

Pic #4     9902     Ready to fly except for the windscreen ... and a motor ...  Camera view distortion shows crooked wing leading edges - an optical illusion - just like the "moon illusion".

Pic #5     9905     The fuse has several patches over ripped tissue holes from that last braided motor flight, full bore into thick canopy branches and leaves.

Pic #6     9906     Underside view.

     M and B are going to try to selectively spray one coat of Krylon Clear Gloss rattle can on the new wing panels, onto that new tissue to bring out the color match to the old tissue.
     I am fighting the temptation to do some test glides with out the windscreen.    ???

I agree - the windscreen came off my little Bostonian Rearwin Speedster and the trim was totally altered - it had done a 2 min plus flight out doors and the behaved like a stroppy pig with gout.

     "Stroppy pig with gout" David ?  LOL    I have decided to wait until I have the one piece windscreen glued in before I test glide the Speedster.  I can wait.   :-\    The ground in Jackson Park has become rock hard and the grass has grown dormant in this drought and heat wave.
     There is a good flying field in Southwest Windsor that used to be called "Titcombe Park" that was named after the Indians who lived here, and sat beside the protected "Ojibway Prairie" complex of protected park lands.  The park had a baseball diamond, hockey rink, and playground equipment, and has been abandoned by the City for a couple of decades now, in order to let it grow back into wild "Tallgrass Prairie" Flora and Fauna.   It is really grown over with grasses  2 1/2 feet to  3 1/2 feet high - yes, the mythical grass ...  These 3 pics are from decades ago - it is all a big field now - no baseball diamond or playground equipment - yes, this was the park we all grew up in.
      The one piece Windshield attachment for the Speedster, has become quite the ordeal, having to size up everything and have it all taped in place an set up for gluing ...   :-\   :)

Rearwin SPEEDSTER 30"  Repair

NEW ONE PIECE WINDSCREEN  (WINDSHIELD / WINDOWS / SUN ROOF)

WINDSCREEN TEST FIT


     Mandrake and Bloodroot wake up early ... anxious and eager to get at that WindScreen, WS.
     First,  M and B use large  2"  green masking tape to tape up the fuse real well for handling.  
     The final plan is to tape up all three arms of the WS in place first, temporarilly untape and lift off, one of the window arms of the WS, apply the 5 min epoxy glue on the window frames,  then lay the "window arm" back down on the window frame, and  "stretch"  tape it up flat and let it dry.  Then do the others one at a time.  The front bottom of the WS is not glued to anything  -  it just sits snug on the nose, with the wrap-around curvature of the top of the nose.

Pic #1     9907   The new  one piece 0.005"  thick clear plastic Windscreen (WS) sits on the table in front of the nose.  Large Green masking tape is ready to cover the fuse with.

Pic #2     9914     M and B have now covered the fuse with big strips of masking tape and have lifted the plane into the Jig.  The fuse is held in its Jig with elastics.  They are now raising the WindScreen into place for a test fit.  The WS has lots of long thinner masking tape strips, that can be pulled taught and taped down, to help hold it into position for fitting and gluing.

Pic #3     9917     There is a single wider strip of masking tape holding the sun roof arm in postion.  

Pic #4     9920    Here M and B stretch out the masking tape strips that are half taped to the clear plastic window arms, and tape down the  "window arms" for a test fit that will hold these WindScreen window arms flat to the window frames while drying.

Pic #5     9921   M and B adjust the tape for a flat tight fit.

Pic #6     9928     The top of the "sun roof" part of the windscreen is centered also with a piece of masking tape.  Now M and B can examine the fit of the WS WindScreen, and make adjustments.

Started the repairs after the Trans Tasman Scale event last weekend. The Avetek Tiger Moth needs a new front bulkheadafter another arrival due to a some what boisterous wind that was not quite as bad as Barkston in May.
The GM160 in the Aerographics Comper Swift has been stripped and the piston O ring replaced as well as being cleaned that I hope will improve performance that appears a little down. Also a longeron has been repaired and the undercarriage on the port side needs repair.
 Finally there is the Auster AOP9 that needs some covering repairs after landing and catching the port wing on a hard packed mound of earth the resulted in a strut puncturing the wing. The bonus was that I have found a stable trim and the model flew well in a breeze.

Took all of the covering off the Lone Eagle as the rubbish tissue I was stupid enough to buy just did not work.  Am I naive because I consider that model goods suppliers should have little integrity where modellers are concerned?  Will now be a short delay whilst I purchase proper stuff.  And visit Liverpool.

Rearwin SPEEDSTER 30"  Repair

NEW ONE PIECE WINDSHIELD / WINDOWS / SUN ROOF

NEW WINDSCREEN   0.005"  thick


     Adjustments were made to this practise W/S.  It was too tight around the LE wing bend, and I tried to widen out that portion  with barber scissors, and made a mess - looks like crinkling.   I had to also cut a thin slice off of the side window panel.   Time to make another New W/S.   M & B found some  0.005"  thick clear plastic sheets, amongst the mountainous wall shelves, full of kits and supplies.

Pic #1     9935    Mandrake and Bloodroot trace out a  new W/S white paper Template from the real "Practise Windscreen",  in order to make a better,  NEW W/S.

Pic #2     9939     This is the  "Draftsman"  result of M&B  tracing the practise W/S,  and then adding the  3/8"  larger outline.

Pic #3     9941     The practise W/S is no good because I carelessly wrote permanent ink on it, without first checking to see if a solvent can remove it without blemishing the clear plastic.   Also, the Template was too tight around the Leading Edge wing bend.
     So then I bought a small  $4  Cuticle scissor with curved tips,  and a  similar, slightly heavier duty,  $6  Nail Scissors with curved tips,  at Dollarama.  Shopper's Drug Mart wanted  $21  for each alone !!

Pic #4     9947     Here M and B cut out the  3/8"  larger outline of the Template.

Pic #5     9948

Pic #6     9949     Here the white paper Template is scotch taped to the new clear  0.005"  thick plastic sheet, and now ready to cut the true outline of the W/S,  and out should pop the new W/S all cut to shape.

I got most of the building done for my test build of my Surpriz Kit (Rene Jossien Wakefield from the 60s). It weighs 93g as is, so with the prop and shaft plus DT hardware I am thinking 120 ready to cover. That leaves 60g for covering and finish etc. AUW needs to be 180g so that she will be at 230g with a 50g motor.

Still a bit disappointed I didn't get to see that one airborne back in May. :)

Been indulging in a little aero modelling archaeology this last couple of days in between nipping outside to see what's flying at RIAT.  Got two sides of the Walthew and its stabilizer so far.  Have a suspicion, utterly unfounded, that this may be the first Walthew MK II built in the UK in over 40, maybe even over 50, years.

Rearwin SPEEDSTER 30"  Repair

NEW ONE PIECE WINDSHIELD / WINDOWS / SUN ROOF

NEW WINDSCREEN   0.005"  thick


Pic #1     9952     The new W/S is cut out, and Mandrake and Bloodroot are now  "masking tapeing" it up, the same way as the "Practise W/S".

Pic #2     9954     One at a time -  the left window arm of the W/S,  and its masking tape,  are pulled off the window frame,  and the window frame is painted with  5  min Epoxy glue,  and the W/S  window arm is laid back down and taped stretched flat.

Pic #3     9955     Now the Right hand side window arm, of the W/S,  is glued and taped down in place.

Pic #4     9960     M and  B mix up more  5 min Epoxy glue, for the Skylight Roof.

Pic #5      9971     The sun roof and the side windows are now all glued up and drying.   The brand new, clear WindScreen,  reflects the white lines of the vertical Venetian blinds, revealing the wavering  imperfections of the see-through plastic.

Pic #6     9976     The side windows appear to be glued fairly flat, and the windshield seems well contoured.   In the background on the wall - - left to right   Nicolai Rimsky Korsakov  1844 - 1908 Russian 64 yrs,  Antonio Vivaldi (The Red Priest) Italian 1678 - 1741  63 yrs,  Frederic Chopin (The Poet of the Piano) Polish 1810 - 1849  39 yrs .

     Mandrake have been working very diligently, but I hear rumors of discontent in the workforce -  Mandrake and Bloodroot want equal pay for equal work,  for Cyborgs,  and they want to be able to pay for their own recharging of their batteries, with their own money ...

Good on the workers - power to the ... er?????????

Having stripped  the rubbish tissue off the Lone Eagle, with no chance of getting some Esaki before I am off to Liverpool (Mr Woodhouse is away) I continued with the cylinders which are now ready for painting.  Having got them ready for painting I decided to give myself a rest from micro work and start a Peanut.

Photo shows laminated tips for fantom - templates for Waco and bits for Lone eagle.

My first choice was a Fairly Fantome by Les Brunning.  But that looks a little complex to trim so also downloaded a Stahl Waco. Long time favourite. Thought I would start the Waco first by cutting out the templates for the wingtips and tail assembly.  Then put on the laminations.  Then realised I had cut out the parts for the Fantome! The parts on the Waco are remarkably similar!!! Never mind.

If any one has done a Fantome it would be nice to hear about it...........please.

        I am impressed. The Fantom is a very elegant machine and the moments look quite good. I will watch with interest. My activity today was further repair work on the Comper Swift that has had a new O ring on the GM160 piston and seems to have improved matters by running longer on a normal charge. The bottom tissue is ready for water shrinking tomorrow and the half of the elevator requires resetting. The Avetek Tiger now has a new front bulkhead out of ply and the new set of wings with revised strut mounting has also progressed as well. All the fiddly stuff. As it was raining hard this was very theraputic.
Are you going to the Nationals in August?

Rearwin SPEEDSTER 30"  Repair

FINISHING THE CRASH REPAIRS       GETTING FLIGHT READY

Marching Orders have come down from above for Mandrake and Bloodroot to get the Speedster flight ready.

Pic #1     9978    Three views of the W/S .     The 5 min Epoxy glue did not work well at all - the test strip really stuck right away   :-\   and I did not wait a full day to find out that it also did not work.   :-[

Pic #2     9979     M and B decide to try a quick fix.  They decide to insert, into pre-drilled holes in the W/S frame,   some small  1/32"  wire pegs to hold the W/S in place,  with a micro-drop of thin CA glue run down the wire.

Pic #3     9980

Pic #4     9988     Drilling the  1/32" holes for the  1/32"  music wire pegs.   These three pegs should hold the W/S in place, hopefully.  The 1/32" drill bit is glued into a 1/32" hole in the  1/8" wood dowel handle,  and points to a silvery wire peg sticking out (better than sticking inwards towards flailing rubber).    :o :o

Pic #5     9990     M and B have tied up a 3/16",  four strand,  each strand 13.5"  (prop hook to rear peg is 15") motor, with medium size Crocket hook, and a length of white string.   The rubber motor "Pushing Stick" head sits on the balsa block in front.

Pic #6     9993     The Pushing Stick is loaded up with the Rubber Motor, the white string is stretched and then masking taped tight, and is now almost ready for insertion, as M and B move it into position.

     I did sneak out yesterday morning into Jackson Park for some test glides and hand winds - got in 8 careful downward launching flights  -  maximum winds were 30 hand winds, started slow with 10 winds and all trim tabs set to neutral - it wanted to go right hand turn at first, so I added a little left rudder tab and now have it circling to the left.  I think into the wind, it wants to end up swooping up a little - downwind it loses height faster.  That spot I did these test flights in, right beside the replica Spit and Hurri, is the only place with a little bit of green grass, and the trees are all small here,  but 9 to 17 paces apart - so just little 5 second flights max here for me, as the Cricket Wicket was, of course, full.   And the rest of Jackson Park is as hard as a rock, and the grass is dormant and cut short - still a heat wave and no rain.
     Well that was enough flights for now.  Got a couple of nice outside pics with the new WindScreen. ( PS - the fuse and framework were all "Golden Oak" color wood stained and dried, before covering with tissue ).  Got to get out of the park now before the Auxilliary Police walk around and see me - they will not be in the park on weekday mornings and afternoons ...

SPEEDSTER   30"    TEST FLIGHTS

     Well, after I ran the dog (more like walked - way too hot) this AM Mon July 16 2018  first thing,  I had to get out flying again.  So for the first time ever, leaving my dog at home and going flying, I snuck out  this second time, this time to the Cricket Wicket, (the Auxiliaries only work 6PM to 10PM on weekdays),  to put in more than 30 finger winds.   Only one side of the Wicket had better grass, but still short and the ground hard as a rock.
     I got in 12 test flights working my way up from 30 finger winds, and trying different wind angle launches from different positions.  The Speedster was flying perfectly, believe it or not, staying level, and flying a nice swooping small left hand circle, and running out the rubber,  and soft landings.  I had a spectator try to take a pic of me launching the plane, didn't quite get it, but here is a couple of pics - one of the Speedster in the air as proof.  I only went as high as 110 finger winds on the last and 12th flight.  A full steady circle left, and not a slow flight either - it moves pretty good - a full left hand circle, and it runs out the rubber and lands softly at my feet, this being a full 6 second flight.   This is the kind of perfect circle size I would need to keep the Speedster within the confines of the Wicket.    It was getting gustier so I headed home - nothing more left to do here now.     Next time,  Winding Stooge !!     I hadn't flown in over 5 weeks.    :(  It feels good to be a rubber power Free Flighter again.    :D

Wow, Mike that looks very clean!!
Is it just paper or how did you do it?

Roman

Roman,

The T-28 canopy framing is printer paper with a layer of white tissue spraymounted on it to match the surface finish of the model.  To make the framing I put strips of tape on the canopy to outline the frames (pic below is from work in progress, frame positions were adjusted some before tracing the templates), traced over that onto tissue paper to get a rough template, scanned that and cleaned it up in Powerpoint, printed the resulting graphic, layed that over the tissue+paper stock and cut along the lines.  Framing is glued to the canopy with thinned canopy glue.  On piece for the windscreen, one piece for the bow, and one more piece for the lower rear frame.

SPEEDSTER   30"    TEST FLIGHTS

     Well, it was pretty windy, so I thought I would just try and replicate some small flights before going to a large number of winds.  Mandrake and Bloodroot tow the Speedster out of the Hangar.   
     The wind was blowing a lot harder than  the Weathernetwork said.   Only made 4 flights and I quit while I was ahead.    :o :o    The last flight was  the best  -  four seconds on 50 finger winds and still flying perfect so far.  The wind really threw the plane around on a couple of flights.   ??? ???   Gonna try tomorrow morning  -  way less wind predicted  -    7 mph Wind gusting to 11 mph by 10 AM.   Mandrake and Bloodroot tow the Speedster back to the Hangar.
       Our three newly fledged Cooper's Hawk babies, in Jackson Park,  are  all doing well so far and flying around.   :)

SPEEDSTER   30"    TEST FLIGHTS    

     Well, got up early, walked the dog, and went back out for some test flights.  Way more windy than the  7 mph  gusting to  11 mph  SE  winds on the weather network site.   Had to launch downwind from the south side of the Cricket Wicket,  where the large trees have bare trunks way up and then the branches and leaves come out  -  the wind really blows right through the bare tree trunks.     Several flights just finger winds - still seems to be flying OK - only got one flight of 4 full seconds on 70 winds - it is still turning left nicely.   The ground is too hard and the grass is too short - those little nose first landings were giving those little  "crinkle crunch" (plastic wheels banging around in the wheel pants),  sounds.    I checked for damage each time on everything.  The last flight it broke the prop blade off near the hub  ???  at the narrowest part of the 9" ( 8  3/4") long  "high - torque"  black prop  - first for me ...  
     That is all for today - time to change that  prop and prop hook wire, and tiny brass washers.   Still no damage to the rebuilt nose, or the reattached wing, or anywhere else so far ...
     Bloodroot throws his arms up in the air "#%$^^*&&#@@!" Mandrake says "Blood, that's enough profanity out of you!"  Bloodroot grumbles ...
     Fledgling Cooper's Hawks -  First thing at  7:00 AM, walking the dog, I heard the young one start calling away as it saw the parent darting in with breakfast, to the big feeding limb of the big deciduous tree that all three young fly into every morning to wait for their breakfast.  The parent took off right away and that young one had no trouble at all, with what to do with that bird dropped off for it.  Voraciously devouring it by the time I got close enough for a far away look.  This is the fourth feeding session I have seen.   :)

Jim, let's see a pic or two please.  Here is Raphael checking down the Tripe-Hounds throat for bananatitis, all clear. Time to pull out the paint and compass for some roundel drama. I'll feature my old school graphics techniques using front mount adhesive. I am an old time graphics designer, producer and installer. Back in the day, you met the client, worked out the design, did all the typesetting, survived the approval process, and the post approval changes, did all the production, dealt with the previews, more changes, disassembled everything, built the crate, called the truck, loaded it, drank a beer then flew to Milwaukee or wherever for the set up. You didn't have eight water-bottle carrying cry-babies with ear phones, sipping designer coffee in pocket-pool trousers going to lunch at 12 and returning at 2 three-sheets to the wind, and going on vacations, just to get a few lousy jobs done!

A very odd thing happened when I was 10 years old... I had the realization that I didn't want to or have to grow up. I didn't and don't envy the boring ass grown-ups with their dopey agendas. Hail Bloodroot and Mandrake!

Sig nitrate dope.  I've done it full strength and thinned 50/50, seems to work the same either way.  Tape down the tissue with about 1/32" to 1/16" overlap (you'll want to keep the tissue grain direction the same on all the pieces), run a line of dope down the seam using a narrow brush, let it dry, flip over and repeat.  Once dry you can handle it like a single piece of tissue.

Went flying. I think my building is Ok but I'm still learning to trim. Got it balanced and turning nicely on 300 winds. Cranked it up to 600 and watched it fly across to soccer fields and into the trees!

Ouch! Hindsight is 20/20 of course. It didn't want to turn under power but turned fine on the glide. Probably could have used some right thrust - I just didn't understand what I was seeing. I figured it out on the drive home. Now all I have is a picture.

I suppose I just gotta hurry up and finish the next one so I have something to fly.

SPEEDSTER   30"    TEST FLIGHTS

LEFT WING TRAILING EDGE BROKEN NEAR ROOT

     I thought I was just going to throw a new prop into the Speedster and go flying yesterday morning when the wind was  4 mph.    I had not checked the model thoroughly enough, after the last test flights, and now I noticed that the Left Wing Trailing Edge was broken near the root, even worse than before.  I did notice it before but I thought it would be OK, but now it is much bigger.   A twist test on the wing revealed the wing structure to be VERY weakened.
     So Mandrake and Bloodroot get back to work, and fit and glue a balsa "Channel" over that trailing edge, for support.

Pic #1     0105     A small length of  1/16" X  1/8"  is bevel - sanded on one side, and glued inside the Channel.  The Channel now has an angled trough, for the TE to fit into,  instead of a square trough. The Channel now fits nice and snug over the TE while straightening out the break in the TE.

Pic #2     0109    M and B check the fit.
Pic #3     0111
Pic #4     0113    Now the Channel is sanded, cut down to shape, and finally double white glued over the broken TE of the left wing near the root.
Pic #5     0114    
Pic #6     0115     All dried and sanded now - but will the airfoil still fly with that interference from the Channel?  :-\  ???

Post by: OZPAF on July 24, 2018, 08:22:28 PM
That was bad luck TWW. It's a good idea to add power in small steps to ensure you have a stable climb with a definite safe turn pattern. start wit about 150 turns and add about 100 turns each step until it shows consistency. Add side thrust as needed to keep the turn. This is only a quick summary - a search here on HPA would find more info.

Trees are a model's natural enemy :) I've lost a few to them - both CLG's and rubber.

Looking at the damage in your first pic Richard - I think it would have been ok to just fill the splintered wood with glue ( brush in some diluted glue first) and then clamped straight. I use pieces of say 3 or 4.5mm balsa wrapped in clear stationary tape(so they won't stick to the glued surfaces) for the straight clamp pieces.

Also CA is good for this type of repair - again after clamping the section straight.

I would suggest that you carefully sand the channels down to match the adjacent TE with masking tape strips protecting the tissue top and bottom.

But will it fly as it is? Yes but not as well and with possibly a slight turn.

SPEEDSTER   30"    TEST FLIGHTS

TEST FLIGHTS FOLLOWING THE WING TRAILING EDGE REPAIR

     Well John, I did go out and fly several test flights in the morning Tues July 24 2018,  with the 30" Rearwin Speedster.  We stopped by the Spitfire and Hurricane, in Jackson Park, for a couple of 25 and 35 foot test glides under power, on a downward angle into the grass, between the small  2"  trees, with 30 and 50 winds respectively.   It flew just fine with a little left turn.   Now we went to the Cricket Wicket.   I made several flights starting with 60 winds and finishing with 150 finger winds and a long 7 second flight downwind and curving left but not too tight and landing softly.   But then I had to stop because I noticed that it had a broken left wing strut at the fuse - a clean long break  :o 8)   that was hidden from me because it fit right back, and laid into, the grain of its long sliver break - a natural press fit under tension - an easy fix - M and B just double white glued it up, and it held the gluing surfaces together just fine.   I had broken that strut two flights earlier,  :(   and I had wiggled the strut after the flight, but you have to wiggle it in a couple of directions to see if it is broken the other way.  ??? ???

SPEEDSTER   30"    TEST FLIGHTS

TEST FLIGHTS FOLLOWING THE WING TRAILING EDGE REPAIR


     All in all, I think I have it trimmed out for this 14" motor now, for a level launch and wider circle, not so tight, and it is descending under power running out,  to a shallower angle into the ground for a soft landing.  I had broken that strut on a bad upward launch where it flew out and up for 5 or 6 seconds, ran out of rubber power up there too high off of the ground, and plummeted to earth at a much steeper angle - hence the "crinkle crunch" I heard.  Good thing I caught that broken strut when I did - I was lucky to get two soft landing flights after I broke that strut ... one more flight and a hard landing could have ripped off the whole wing ...   :-\  ???
     If the weather is good tomorrow, it is time for the Winding Stooge, and time to start working upwards from 150 winds in small increments.  I think that the more winds I put into it, the more it will want to turn left and climb.   I plan to try to counter this with clay noseweight and clay weight on the outer right wingtip.   The model weighs  102  grams anyways.  The file folder cardboard tabs on the elevator and rudder seem to adjust and hold just fine, and I think I am able to adjust the circle with them.
     Well, it seems to fly so far with that big "Gurney Strip" Channel.  It is way too soon to make any definitive conclusions, though.

Hello and I want to know what is the name of this model that flew away across the soccer field and went into the trees? I just have to ask. Looked like a good flyer. Are you a member of the Flying Aces Club? I live in San Antonio, Texas and am a member of the national club as well as the Squadron Leader in town for the Alamo Escadrille.   I really like old time rubber models like the Korda Victory and Gollywocks too. I also like the King Harry for two bit plus one and then Embryo models like the Big Cat and Debut . Always working on something and currently I am building  a peanut scale model Heinkel P-1077. This will be my third P-1077.I also like the jet cat models and currently flying the ME-262 and the A4D Skyray.

REARWIN SPEEDSTER   30"   Dumas kit

TRIMMING FLIGHTS

  Well , the broken wing strut glued up fine overnight -  all is solid.    
Got back from running the dog, and it is 9:00 AM  72 deg F (real feel 91),  Winds are 7 mph from the North, gusting to 11 mph,  88% humidity.   Grabbed the pack, dog, and plane, and headed out to the Cricket Wicket of Jackson Park.
     Well I smashed it up again,   :P   on this latest adventure, but I will fix it. :)    I got in 12 beautiful flights, all running out the rubber, coming down low and landing softly.   I was in heaven.    The first three flights were finger wound, working up to 80 hand winds on the third flight - perfect short flights.  Then I hammered in the steel tent pegs into the hard ground, to set up the bungie cords of the Winding Stooge.  I started slowly with the winds in the Stooge, and I put a little weight into the nose, ahead of time.   I have full up on the right elevator tab, and a little down on the left elevator tab, and a little left on the rudder tab.   Longest flight today is 22 sec.

Flight #4  -  225 winds,  8 seconds, perfect left hand circle
Flight #5  -  375 winds,  14 seconds,  1 1/4 circle,  as it came around full left hand circle,  it started doing the slow little right hand circle, into the wind, at the end, and tried to split the two huge spruce trees, flying very slow into the wind and hitting midway high up, and so softly, it floated down with no damage.  (Whew ...)

Flights #6 to #12 were all done on 450 stretch winds of the rubber motor - 4 strands of  3/16" each strand about 14" long, prop hook to rear peg is 15".   These last seven flights were 15 sec, 15 sec, 22 sec, 14 sec, 17 sec, 18 sec, and 18 sec. - these flights were magical, in that they all ran out the rubber coming in low, and landing softly, and circling on average one and one quarter circles.

     The last flight was the CRASH - it had made one perfect circle and then continues on the next half circle downwind, but swinging to the right dangerously close to the treeline, downwind going away.  It then started circling left safely, just staying inside the tree line, that is, until it ran out of rubber, and did the right hand turn at the end, going straight for the Cricket fan stands in the treeline.   :o :o   It came in with a perfect, slow, low landing, greasing it (I could hear it), right on the start of the foot-trompled, hard packed dirt, right in front of the stands, and then taxis forward,  under the final winds left in the motor, taxis forward over the hard dirt, and right into the metal upright of the bench seat, and bouncing right back off it a little bit to a stop, with the prop still spinning its final turns ...  ???

Pic #1     0130    Far out going left.
Pic #2     0137     Almost overhead going left - best shot of the day
Pic #3     0138     Prop is frozen, framework and sillouette against white clouds.
Pic #4     0139     Coming back to me on a full circle.
Pic #5     0140     Greased landing but right into the metal upright.
Pic #6     0141     Broken Right Wing Leadine Edge (LE) by the number "2" of the call sign.

    The neatest thing is the launch - you can throw this   30"    'Jumbo'  Rearwin Speedster  like a spear, straight out, down wind or slightly off, and it shoots out really fast, and you can tell, just when that spinning prop, finally catches up with the relative wind, and takes control of the plane, and powers out in aerodynamic flight, with the rubber motor kicking in ...
     My only sole objective now, this summer, is to beat my 34 second record mark.  I only had one 29 sec, one 30 sec, and one 34 sec flight.

 ;D  flew my zero. good news it flies nice under power with lots of right thrust.

bad news still turns left in a circle but in a nose down attitude. as soon as power is reduced or is off, down she goes .  I've try trim tabs and they help up to a point. too much up elevator and it climbs straight up and then stalls,

any comments.

Post by: tom arnold on July 26, 2018, 08:28:24 PM
Jim, your Zero acts like it needs a bigger stab and to move the CG back. A good starting point for the CG for a conventional gear is a teensy bit ahead of where the wheel touches the ground in a level position. The fact it needs a lot of downthrust and that "up" elevator is touchy is the tip off. If the stab is too small, it will usually work fine under power with the prop blast but when that goes away it doesn't have the downward lift to keep the tail level and up goes the tail. Ozpaf's suggestion of test glides with no prop or rubber is excellent. I love to do that and then hate to put in all that prop and motor weight because I have so much fun gliding.

Hi all,
I got a couple of tip launched gliders ready. The big yellow one is a spin-up ... it is new so untested. The orange one is my tLG rendition of Martyn Cowley's classic Gold Rush HLG (one of the first successful HLG builds from me back when I was a teenager in south Africa and the ONLY guy flying free flight... perhaps in the entire country).

SPEEDSTER   30" Dumas

REPAIR OF RIGHT WING LEADING EDGE    and    BOTTOM FUSE STRINGERS


     Mandrake and Bloodroot, cyber super soldiers from the future, are summoned back to work on the Speedster repairs from the crash on July 25 2018, in Reply # 819 above.

Pic #1      0155     Mandrake and Bloodroot set up the 4-piece portable fuse jig holding plates, to hold the plane.

Pic #2     0147     The Leading Edge section, of the right wing, is broken into two small pieces, along with a top  1/16"  sq spar stringer, and three fuse bottom stringers.      A Leading Edge  3/16"  X  1/8"   "Backplate", and a  1/16" X  1/8"  broken spar doubler, sit on the wing, cut out for fitting..

Pic #3     0143     Test fit of   3/16"  X  1/8"  Leading Edge backplate and  1/6" X 1/8"  Spar doubler.

Oic #4    0152     The backplate and spar doubler have now dried.  M and B now glue back in place, the original two broken pieces, of the Leading Edge, to the front of the LE backplate.

Pic #5     0163     M and B  test fit three  3/32" X 1/8"  fuse bottom stringers to replace the three smaller broken  1/16" square fuse bottom stringers (broken from poor handling in the winding stooge).    Pic of  Adult Cooper's  Hawk ( 28" wingspan ) on the monitor screen in the background.

Pic #6     0168     everything is all glued up and dried and ready for four panels of tissue.

Sorry I missed this. Flyace has it right. The plan is available at Oakland Cloudbusters as well as Outerzone. I'll probably build another - these 20" span models are (barely) big enough for my fingers and still small enough for the smaller fields I have around me.

Had a great morning at the flying field.  Trimming the T-28 was much more productive than the first session (having appropriate decalage seems to help...).  I think this model is going to require a bigger flying field:

The air was getting frisky as I broke out the jetcat - just about lost it today with a 2:15+ thermal flight!  Was very fortunate to find the model under a tree in a parking lot a quarter of a mile away.

That was lucky Mike. Your T28 is flying very well. Did you mean that you only have 1 deg longitudinal dihedral(decalage) on the T28? Where is the CG as a % of the root roughly?

Thanks John.  CG on the T-28 is set at about 40% of average chord.  McCombs calculations give a tail volume of .693 with recommended CG ~41% of average chord.

Crabby the wings have glass on the joints and ply reinforcement tongues at the joints at max airfoil thickness. However, the main thing is good stiff but light wood with flexibility (as apposed to brittle). I flew the new spin today and she goes beautifully. Got her in several nice thermals. Great glider.

SPEEDSTER 30"  Repairs Finished 

     Well, the Speedster repairs are done -  only took a couple of days ( unlike the smashed in nose and ripped off wing that took 5 weeks to fix ).  The Speedster is looking as good as she is going to get.  Unless I get a flying field with no trees, that is all for the Speedster.   Thanks for all of your support.
      I took it out for some outside pics by the Spit and Hurri replicas in Jackson Park.  The Cooper's Hawk nest is also right beside the warplanes in thickest section of branches right beside the trunk, of the top of the middle of three big pines.    The fledgling hawks are always hanging out in a big clump of trees, and every morning they are in the big deciduous tree waiting for their breakfast and calling away for their parents, and there is one big limb that they feed on.   I met another birder and master photographer first thing yesterday morning, who was kind enough to send me these three excellent pics of these fledgling Cooper's,  that he took with a huge  $2500  telephoto lens.   We go right by these hawks every day walking my dog a few times each day.  Now it has been three weeks since they flew out of the nesting tree.   We are really quite lucky to be doing this ultra birding for Cooper's Hawks so close to those young hawks - we literally keep an eye on them and see them  every day. 
     How are your little Kestrel falcon fledglings doing Stephen ?

     Thanks John - I have finally come to the full realization   ???   that the reason that I cannot muscle in  more that  450  winds (I should get 700 winds), on my yellow winder, is that the four strand  3/16" rubber motor is bunching up at the rear peg against the "center of fuse" crossmembers - the rubber motor angles down rearward.  And I just saw the answer today - "to move the rear peg forward a bay .. or  maybe two ..  to get more rubber clearance" - and I can also raise the rear peg a little higher also for more clearance, in addition to moving it forward one bay.   I will have to think  about it - and examine that rubber motor that is in the plane now, for nicks.   The ground is so dry and hard, and the grass so tan and dormant and trompled upon in the Cricket Wicket, it is quite risky to fly your plane into it with hard landings ...  :)

Keep 'em flying!   ;D

Richard, are you aware of the rotating motor peg? You use a larger diameter peg over one one you have and it rotates so the rubber won’t bunch up! You know this move?


Title: Re: What Did You Do Airplane Wise Today?
Post by: BG on August 01, 2018, 12:02:05 AM
Crabby I have heard this about rear pegs before but I have to say it make no sense at all to me. Why would a rear bobbin do anything to prevent bunching? I suspect that this might be a myth .... the best cure for bunting that I know is a well braided motor and moving th rear peg forward where there is more room in the fuselage.

Well, I suppose every specific condition has its cure, or cures. Some guys swear by this rotating peg system. I have used it but I rarely get a bunched up motor in any case, so I am a poor candidate to defend its virtues. Its not a myth, I have seen some accomplished modelers use this technique. Could be you never get a bunched up motor because you braid your rubber and tie off the end, thus the problem is circumvented. Here is a pretty good explanation of the idea of the "wobbly peg" http://www.hippocketaeronautics.com/hpa_forum/index.php?topic=20023.0

Title: Re: What Did You Do Airplane Wise Today?
Post by: Prosper on August 01, 2018, 08:37:25 AM
Richard, I don't quite understand your winding issue - are you not stretch-winding your motor? If you stretch wind it you should be able to get all the turns you expect on it, and it will only clump up into bunches as you feed it into the fuselage. At that stage the bunches should be evenly distributed and not just at the back.

If there is a free-sliding sleeve or bobbin holding the back end of the motor on its peg, and there's a large eccentric clump of knots flailing round at the back, and this impacts a structural member, the free-sliding sleeve allows this impact to shove the whole motor axis sideways*, and then back again as the clump hits the other side of the fuselage, therefore freeing the motor to continue spinning until it's time for that particular clump to unravel. One can observe the sleeve or bobbin busily shuttling from side to side. This much I've seen. If everything's set up right it can prevent the motor actually locking up. Where the fuselage cross-section is square or nearly so I imagine a clump could still lock against the top or bottom of the fuselage.

A locked-up clump will increase motor density behind the CG also, thus affecting the glide to some greater or lesser extent, but remember that that extra density will have been present all the time the clump existed (i.e. in the powered flight phase too).

However, whereas I don't see the peg sleeve or bobbin wheeze entirely as a myth, I don't pay it much attention. A reliable low-friction sliding setup adds weight and I think it's worth - where small, scale models are concerned - considering how that extra weight behind the CG measures up against the turns locked up in a big clump (say, 2-3 seconds flight). A bobbin might weigh a gram, and require 1.5 or 2g noseweight to balance it, for example. 3g extra weight for the same power. That may yield full motor turns, but flying a heavier model. The result could be the same as a slightly shorter motor flying a lighter (and simpler) model.

Stephen.

*at the cost of lots of energy lost to friction

P.S. Richard the kestrels junior are now grown up - or they thnk they are, and are striking attitudes and sulking. Seriously, they have dispersed so I haven't seen one for a week or so.

I spent a very hot afternoon in the workshop but I did manage to sort out the DH60 in anticipation of the Nats at the end of the month.

After lots of flying and lots of nose over landings the fin was suffering a bit. Cyno had saved the day a few times but it was looking like a witch's nose so it was time to build a new one. Nice easy job , though why I epoxied it on is lost in the annals of time :-( digging out the old glue without destroying everything else was not fun. i glued this one in with Aliphatic.

Some of the dummy rigging was replaced too ... Thanks again for the elastic Bill

 I also replaced the screen framing. I had done the original version in paper painted and varnished which looked good until the the damp got in and it started to fall apart.
This time I made the frame from a small strip of Ali Litho plate. I scored it down the middle to make an angle section and then very slowly and gently bent the angle section in to curve. As I bent it the angle opened up a bit but that actually seems to fit the profile of the full size. The acetate screen was stuck on with canopy glue, held in place with a rubber band around a battery while dried. The whole thing was then stuck on with more canopy and does the job to my eye.

Not sure if I'll get a chance to check the trim before Barkstone... hopefully I will

REARWIN SPEEDSTER FLIGHT REPORT   July 29 2018

Well, I could not resist going flying again this AM with the  30"  Rearwin Speedster, even though the wind was marginal.   I was just trying for some slow short relaxing flights, as I have not yet moved the rear peg ahead one bay, in order to get more space for the rubber motor.  I only got in three flights, before once again, on a hard third landing, I broke the right strut fuse attachment point, and bent the prop.  The first flight was perfect 360 winds (not 450) and I still got the perfect 16 sec left hand turn flight and a very soft landing on one full circle - BUT - when it came around on the circle it came further wide in behind me, straightened out from the circle, and it casually glided down past the tree trunks of the perimeter !!  ??? ???   I tried launching the next one further out in the middle of the Cricket Wicket where more wind was -  just an 8 sec low flight before hitting the grass, and the third I launched it badly at too high of an angle - see pic - it turned left into the wind and got slowed right down, and then straight into the ground almost, from a high stall, and a little bit of crash damage "flesh wounds", easily fixed.  
     So we packed up, stopped on the way back to look at our young fledgling Cooper's Hawks (5 weeks out of the nest), and came home to see if any pics turned out.

Pic #1     0228  THIRD FLIGHT LAUNCH
Pic #2     0229  HAWK RIGHT IN THE MIDDLE  - a sort of grayish looking oval of the breast with the hawk sitting at the end of the bare leafless part, of the 2" diam. branch that goes up to the right at  110 degrees

I have never tried this thread before, probably because I am too irregular to work in days.
Actually this day started a little after midnight on Wednesday.  I was pondering if I ever would build a glider and put some radio in it when I realized that the thingy I would need to move the rudder, which I always called an actuator, was called a servo by RC experts. This set me to thinking; do I need to read a book on RC? I looked on ‘Amazon’ and all though they had some books it seemed too complicated to buy anything so I tried ebay and a nice lady in the south of England had a copy of George Stringwell’s book on Radio Soarers which, with the help of ‘PayPal’ I managed to order in a few seconds and it should be here tomorrow so I went to bed happy at my usual time of 3am. In the morning I realized I had no time to read books because I was supposed to be making a new propeller for my indoor rubber job and the season will start at the end of the month.
So I wrestled my walking frame outside the door and plodded down the path (in my bandages, shoes won’t go over them!) to the garden room to fetch my electric drill so that I could sand down some tooth picks for my propeller spars. I just chuck the tooth picks in the drill, set low speed, and pinch them in a ‘V’ of sandpaper.  The nuisance is turning them end for end to do both ends.  If you haven’t tried this I can assure you it is simple; if you do it in a better way I would be interested to hear.  I have cut some propeller blades to shape in 1/32nd sheet. Just wondering whether to thin them before soaking and twisting or thinning them after soaking and twisting. Its getting towards 3am so I had better say goodnight.

Hello John.  Years back like you I got the books on radio and struggled from there. Joining a club and mixing with folk who had been doing it for a while was the best way of "learning" the craft.  In case it is on any encouragement today R/C gear - particularly for a glider is pretty cheap and very light.  I have successfully used a Receiver weighing a few grammes that cost less than £10, a servo even lighter and cheaper, £3. and batteries that weigh almost nothing and again pretty cheap.  The biggest outlay would be the Transmitter but that is one off.  Yes there are some technical aspects to consider (compatibility etc) but it is a lot easier today in my view and very much cheaper.

However  for a little while now for me radio has taken a back seat because small FF models are the thing!.  One only has to look at the enthusiasm of people like Richard here and the fun he has to see what it is all about.  Clearly Dog (a name would be nice Richard) is a bit of a philistine as I detect an air of boredom?

I see your point John - posts on here should all be shortly before retiring - at the end of ones day!  Whenever that may be.

You have made a good choice there John as George Stringwell as you may know has been an authority on RC for many years and a top thermal glider pilot in his day and is still active - apparently preferring small tissue covered RC models at the present.
Your Lulu would make an enjoyable RC glider with reduced longitudinal dihedral with elevator and rudder control.

Derek,
Much as I like you I cannot really agree with you! I think the thread discipline is often poor but to shew how malleable I am I will follow your suggestion.

All day today and a lot of other days recently I have been re-reading an advertizement that appeared in the last issue of BMFA News. It is for a 'Microzone' MC6A, 2.4 Ghz Multi purpose 6 channel Radio Transmitter and Reciever.  The price is £49.99.  I know virtually nothng about RC equipment so can someone who does know something about it please venture an opinion as to whether that might be a good buy or some kind of swindle?  My daughter says:"just get it, it costs me that much every time I fill up my car with petrol."

Why or how could you not agree with Derek? This thread is under General Forum, General Discussion. So if an airplane is involved it is legal fodder.

As to your radio question, is it a good buy really has to do with your expectation. But it is not a swindle. I wouldn't want it as it is limited in the receiver options.

But if looking for the best RC value the deVention Devo 7e is good so is the IRangerX IRX-16X. These are low cost highly flexible radios that don't lock you into one type of 2.4 protocol. This flexibility does come at a cost, as these might not be Plug and Play as some firmware updates and other programing magic is often needed. But the hardware is robust and well suited for out RC toys.

I've seen this kit flying many grand children's aircraft.

'Microzone' MC6A, 2.4 Ghz Multi purpose 6 channel Radio Transmitter and Reciever

I must admit that I have never heard of this company and do not have first hand information on their products. A Google search has at least indicated that on the surface the set looks quite reasonable and is of full allowed output power at least indicating full range.(liable to be around 1.5km on the ground). Range was not specified on any of the specifications I saw listed. It appears innovative in that it has no external aerials on either the Transmitter or receiver which is a practical plus.

Just as importantly for you John may be if they have a lightweight receiver as the one supplied appears to be 10g. Servos's apparently are not included but these can be sourced elsewhere - ideally to suit your particular application. These can be obtained down to 2.5g in rotary output form. The thing to keep in mind here is that while any servos will work with the receiver only A Microzone receiver will work with the radio.

Also Transmitters come in 2 basic stick modes - mode 1 and mode 2. I would suggest googling  transmitter Stick Modes but briefly Mode1 has the throttle and Aileron on the right stick, with elevator and rudder on the left. Mode 2 has aileron and elevator on the right stick and throttle and rudder on the left.

Which way you go will depend largely on who teaches you or fly's with you as either system generally becomes comfortable with practice.

The price is good and if you are happy with the receiver weight - why not choose a mode - preferably after having a talk and play with someone and a play with a transmitter, and go for it.

This is only a brief coverage and hope it helps.

John

I had a long flight at the Timperley Gala (30+ mins) with a Gollywock which we 'tracked' down to a tall tree three miles away in a large estate. Unbelievably, said tree is thirty yards away from a house wherein dwells a professional tree-climber. He's already got the fuselage and tail but didn't know about the wing (which has the tracker in) which must still be up there, although the battery has died. Fingers crossed he'll find it today.

Finally started covering the Walthew MKII.  Bit of an experiment pre-shrinking tissue for the stab with Eze-Dope. The original build instructions say not to water shrink tissue on the stab. because, "you'll end up with a reef knot".  Not convinced the Eze-Dope has worked; the tissue feels much "softer" than I'd hoped it would be and I think it is likely to not prove robust enough in use.  May yet have to resort to using non-shrinking dope on it. We shall see.

Yet to glue and bind the wing bearers to the piano wire supports, that'll be done after the fuselage is covered.  Bare bones weight sans wing bearers is 33g which, if the Swallow is any guide, bodes well for an initial trimmed weight somewhere in the low fifties.

Obligatory pre-covering bones pic.

Further along on the Big BF. Stab is now covered and wing construction has begun. Also got moving on finishing up my Sky Gull. Warps had crept back in on the stab and fin, so they've been soaked with water and pinned flat to dry. Hopefully they'll stay that way now.  I've bought some 12" Chinese props, so I should be moving right along on this and my Miss Canada. Prop making always slows me down.

Not really something airplane wise although I have been doing such stuff, but yesterday evening, quite by coincidence, I learned how to pronounce the Italian (Sicilian and Calabrian mainly) surname Garofalo. I was aware of the name from having bought and built the Comet 24" Mustang designed by Vito M of that ilk back in the late seventies. Up until last night I have always thought the stress was on the a of alo but now I know that it's on the o of ofalo, the first o that is. The plane can be built to look very beautiful, although it wasn't by me, but is a bit too beefy for rubber. Probably quite feasible as a conversion to RC nowadays. The stowable undercart is a particularly nice touch. Probably could be made to work convincingly with small electric motors.

Had a quiet little festival of creative and artistic swearing featuring many new and utterly novel oaths, imprecations, curses and blasphemies as well as a jolly good handful of traditional ones.

Found that the tissue had pulled away from one of the rib undersides this morning after the application of the 30% coat of Eze-Dope last night. Couldn't persuade it to stick back down and this evening's attempt at re-covering the panel went atrociously wrong so have stripped that off as well and walked away from it. 

Annoyingly the other sheets of white tissue I have aren't quite the same shade as the one I used for the wing, stab.  and fin because, of course, there's not enough left for a third attempt at the wing panel from that sheet is there?  Hey ho. 

Try again tomorrow, or the next day, or whenever I get my tissue covering mojo back.  :)

Some people I have known cover a wing panel, particularly on the underside, in a different colour as they say it helps with seeing the model and also gives an idea of which way up - or which direction it is going.  Sounds plausible?  Sympathise with you though - it seems there is a "force" deliberately  set up in the aeromodelling world to try ones patience and fortitude?

1) fuselage complete
tail complete
weight 15 gm approx.

i built this as a half shell using my own wood the wood supplied is very hard  and is designed for a full shell construction.  Half shell is easier to work with.


I also went flying outdoors with the RC types.  I flew the Comet hellcat, Baby Blue and the expanded guillows zero.  i got one flight of my f5f before it started raining.

finally i put in an order from AC supply. I like their prices.  ( I'm paying for from the profits of a certain stock I own.)

Yes, and probably why al your models come out very light.  I think the real benefit was being able to see if the model was flying away or towards you.  Assuming (unlike me) you remembered which wing was the different colour.  But then again one needed to see the model as well. 

But things can turn out well Lurk.  I threw a tantrum over the rubbish grey tissue I bought for the Lone Eagle.  Esaki apparently do not do grey of any shade I was informed.  And then I found a couple of sheets of silver Esaki I had forgotten I had. Now apparently you apply this silver side in.  It shrinks well and has a god “wet strength”.  Once shrunk a thin coat of dope brings up the silver colouring and it does not look bad at all.  I suspect it is a bit heavier than the coloured Esaki butbst most will only need a light dusting of silver for a better looking finish.  So ended better than I thought but still sore over the pound store lavatory paper!

As a slight change from the delicacy of the Peanut Waco I have started a long overdue Vic Smeed Coquete.  Gosh how easy it is handling 1/8th square and upwards compared with super light tiddly stuff.  But the Coquette seems a bit over spec. and have already chosen smaller dimensioned timber to appease the weight saving habit I have been developing.

Silver Esaki must be applied "wet" but it works very well silver side out.  The only issue is that you can't paint on the silver side.  All markings in the photos are either glued on tissue or Chart-Pak tape.

SPEEDSTER REPAIR after July 29 2018 crash

Back to work on the 30" Rearwin Speedster, after obsessing on Gliders and WildFires, and reading HPA ... and general lazy web surfing ...
     Looking at the strut break - that crack was  1/16" down from, and parallel to, the previous crack on the fuse mounting plate - this shows that my previous double white glued repair was solid.  :)

Pic #1     0255     The break is where the top rear of the landing gear pants, pushes up (and in a little), on the fuse strut and mounting plank, when a hard landing pivots on the front LG wire coming out of the fuse.  
Pic #2     0257     This break easily fits right back into its crack.
Pic #3     0258     After cutting out the fuse panel tissue, Mandrake sands the edges prior to double white gluing a supporting infill plank. Bloodroot cuts only three edges of the tissue and decal, in preparation to gluing in the added rear motor mount plates,  one bay ahead.
Pic #4     0265     First, the cracked strut mounting plate, and the strut tip, are glued back into their spot,  and let dry over night.  Bloodroot inserted a spare "expansion" plank to hold the glue contact surfaces tight while drying.  
-on the screen  -  ALCATRAZ GLIDER ESCAPE
Pic #5     0268     Mandrake test fits a   3/32"   0.37 gram, infill plank "strengthener", above the fuse strut mounting  plate.   Hopefully,  this plate will prevent further such crash damage.  Bloodroot measures up the new rear motor peg plates sizes.
Pic #6    Hello to all at HPA,   :D    from the Flower Garden of Jackson Park, Windsor, Ontario, Canada - had to play early in the AM -  90 deg F in the afternoon.  (Trapper is peeking out from under the bench).   :)

Kitty Fritters - thanks for the comment on the silver esaki.  I have tried to shiny side out -  but in this case I wanted a "dull" finish because  the original aircraft was doped silver on cotton so shiny side in produced a slitty better image.  I am waiting for things to dry and will then weigh everything because I am getting bit sensitive about  weight! If I have a margin I will probably give it a dusting of silver acrylic.

The yellow  15:1  K & S winder.   Question about the winder - does the winder's wire shaft with the hook at the end - does this shaft freely extend out to a stop, about an inch extension, and slide back in an inch, right up against the blue bullet nose front bearing of the yellow shaft housing?  It is always pulled out to the one inch stop, while winding.

Title: Re: What Did You Do Airplane Wise Today?
Post by: flydean1 on August 17, 2018, 10:47:36 AM
That's pretty much an indoor winder for small cross section motors.  Not a lot of leverage as well.  Best is the Rees "Scale Winder" which I think some vendors on this list have available.  Do not neglect lube, or a winding tube.


Title: Re: What Did You Do Airplane Wise Today?
Post by: billdennis747 on August 17, 2018, 10:55:44 AM
Yes it does. I didn't even know there was a 15:1 KP. I have 10:1 and it's only useful for small motors, as IF says. It gives up on 4 strands of 1/8"


Title: Re: What Did You Do Airplane Wise Today?
Post by: Indoorflyer on August 17, 2018, 11:06:19 AM
KP15:1 is a light duty winder, I never use it for more than 2 strands of 3/32". It does not have sufficient mechanical advantage to handle the larger cross section rubber.


Title: Re: What Did You Do Airplane Wise Today?
Post by: Pete Fardell on August 17, 2018, 11:09:41 AM

     Thanks guys - now I found it - my  yellow 15:1 KP Winder is only good for  1/8"  rubber ( I really had a feeling that it was the winder, and not my rubber motor bunching up ),  and the  10:1  winder  is good for 3/16"  rubber.  Never knew that before ... The heavy duty one is quite expensive - around $125 - have to think about that ... - I have four strands of 3/16"  rubber in the Speedster - maybe I will just try the  $20   10:1 winder for now ... back to the building board.

Title: Re: What Did You Do Airplane Wise Today?
Post by: Indoorflyer on August 17, 2018, 01:21:26 PM
The Rearwin is a large model--4 strands of 3/16" will still be too much for the 10:1 version. The KP specs assume a single loop/2 strands.

I like Bill's suggestion, it will take more turns, but the drivetrain will be more robust. Just make sure your anchor doesn't pull out of the chuck!


Title: Re: What Did You Do Airplane Wise Today?
Post by: Konrad on August 17, 2018, 02:05:35 PM
Try to mushroom the back end of the drive hook (Anchor). Place this mushroomed end way down into the chuck. Make sure the chuck jaws clamp on the anchor shaft not the mushroomed end. What you are trying to do is make sure that the mushroomed end act like a safety stop should the chuck jaws loosen.

I like to drill a cross hole in the hand drill to accept the drive hook.

Now the disclaimer. It is not a safe practice to use friction jaws (a chuck) to hold a drive hook or anchor in a hand drill for the purpose of winding a rubber band.

All the best,
Konrad

Richard, I just use a 3.6 : 1 hand drill to wind my bigger models, I lengthened the hand grip and also the winding handle and I can easily wind things like my 1/12 scale P51B which uses 12 strands of 1/4 rubber. For you case this would not be necessary.  As Konrad suggested the most important thing is to put a retainer on the winding wire that sits in behind the chuck, I just bend a 90deg tag so it can't slip out.

     Hi Dave - thanks for the tip and the pics especially.  ;)  I have a couple of more Newbie questions - what is the size of your chuck, and what size is the drive wire thickness, and did you bend the hook on that wire ?  
     I have been looking for these hand drills, appx $35,  but I cannot find anyone selling them in Windsor, Ontario, Canada.  Does this Rolson 48107 Double Pinion 6mm Chuck Manual Hand Drill, or similar hand drill fit the bill?    Anyone recommend a specific hand drill?  Will any old Yard sale hand drill do ?
     Dave, I see your point in lengthening the hand grip and winding handle.

Should be able to pick up a second hand one fairly cheap. Yes the chuck is 1/4" - 6mm, the wire is bent from 16gauge/ 1/16th/ .062 music wire and I have either a corresponding winding loop on the end of the prop shaft or a loop on the end of the rubber motor, for your size motor you could use a suitable "O" ring.

Post by: billdennis747 on August 18, 2018, 04:35:43 AM
For complete safety, you can either throw away the chuck, drill the shaft and securely bind the hook (that way, no-one will 'borrow' your drill) or make up a wire loop to go behind the chuck, bend it forward and solder to the hook.
It's better to get a decent drill with good gears - a cheap one will bind up with bigger motors

You should easily be able to find an old hand-drill for peanuts as 42 billion of mostly good-quality ones were made before the advent of electric-powered plastic ones.  Try eBay or similar?

With a ratio of 3.6:1 (or whatever your eventual drill produces) calculating turns shouldn't be that complicated:
28 turns = 100 winds - your basic unit (actually about 27.78 but don't sweat this)
14 turns = 50 winds - your half unit.
7 turns = 25 winds - your quarter unit.

Instead of relying on brain-work at the flying field (e.g. trying to work out 475 turns), just construct a mini table in permanent ink on the drill (disc) itself:

WINDS - TURNS
...
400 - 112
425 - 119
450 - 126
475 - 133
500 - 140
...
etc

I did nothing airplane wise today, nor have I for a few months due to work and family stuff.

But on Thursday I purchased a 4' high x 2' wide four-shelf softwood bookcase to get my yet modest collection of aeroplane and modelling books off the floor and tidy alongside my making table  :)

I go with what Bill has said, well  almost - here is what I fashioned out of a hand drill that is more than 50 years old.  The hook could be neater but that was a last minute job and having served OK I have not got around to changing it!

     Hi DavidJP .    Your old fashioned hand drill looks like just what I need to find - but where (?).    I like your padded  "stirrup"  handle - did you make that part yourself ?   
     I also like the longer handle on the hand crank of dputt7's old drill, that he put on.    Great ideas in pictures.

You can find drills at yard/garage sales and local auction houses. I've been looking for the past couple of months, but got outbid on the only suitable one so far. Do look for one with 2 pinion gears. Found one at an auction last night, but it was a much too big breast drill and went for more than I was willing pay in any case. But I did score a Stanley/Bailey No. 6 hand plane from pre WWI.

Have you tried steaming them?  Can work.

Haven't tried steaming, but I'm sure it wouldn't help. I re-read Flyguy's thread on his build and see he used larger stock. I suspect the size called out on the plan version I've got is simply wrong.

Yep, I checked the plan again and there's a side section view of the tail construction and the wood drawn is clearly thicker than the 1/16 thickness given on the plan.

Hello Richard - yes I made the "padded" handle - bit of flat aluminium which bends easily and the padding is some apple wood I had from my model boat building days!  Lovely stuff to work and sacrilegious really to use it  for that but had had it for ages and have some more.

Or best of all, forget turns and make a simple rudimentary torque meter.

I have a winder made like DavidJP.  His handle is better than mine.  I  have a simple aluminum strap with a dowel for a grip.  Can wind just about anything.  Max so far is 16 strands, 1/4" Black Champion.

Interesting thoughts on winders. I've used a drill in the past but if I build another large rubber model I'll probably get a KP winder too. The last one I built though, was... er 37 years ago !

My afternoon was spent sorting out my DH60 for next weekends Nationals. I've made new, more scale like bracing wires from fishing line and painted them silver too. Not sure this will elevate it to top notch static scores, nothing short of a complete rebuild would do that, but it looks the part a bit more which is good for me.

 After two years flying and some pretty cack-handed trimming on my part ... well its all a learning curve... it's looking a bit tatty with some cracks appearing in the sheeting. It's such a nice flyer now ( on a good day) I might have to do a bit of a rebuild over the winter

SPEEDSTER 30"    REPAIR after July 29 2018 crash

Pic #1     0291     Mandrake finishes up the "Golden Oak" staining.  Bloodroot adds a strip of masking tape, folded over little tabs on the ends, adds this to the decal/tissue strip to help glue the tissue/strip back on.
Pic #2     0298     Both rear peg anchor plates are glued up with 5 min epoxy, and "stretched" taped into position to dry.  On screen is the largest version of the Cooper's Hawk (28" wingspan)  -   the GOSHAWK 42" wing span.
Pic #3     0301     M and B use metal side cutters to snip apart the bent wire prop shaft.   A closer look at the old rear peg hole, shows it to be gradually elongating ovally from rubber tension.
Pic #4     0310     The newly "prop wired" nose block is  13 1/2"  from prop hook to the newer forward rear pegs.   The motor installed is  13 1/2" and barely holds the prop block on ( I will use a couple of pieced of scotch tape to hold the noseblock to the planked forward fuse).
     My selection of rubber motors is ready to go.
Pic #5     0318       The two rear peg plates weigh  0.11 grams each (but I also have less rubber at the rear now also).
     Time for some test glides and bring the modelling clay, with 30 turns or so of the prop to start - just to see how the prop stops and how the plane glides down.   Have to wait till tomorrow -  the Cricket Wicket is full and so is the park.   I will sneak in in the morning when no one is there.
      Good work Mandrake and Bloodroot.  I'll probably have more work for them real soon ...  :)

Keep 'em flying ...  8)

SPEEDSTER 30"   TRIMMING TEST FLIGHTS  after repair from July 29 2018 crash

     We left at 9:45 AM for the Cricket Wicket, "loaded for bear", with stooge and everything.    72 deg F (feels like 86),  winds from the East 6 mph gusting to 9 mph,  88% humidity.  The grass was green and not too short, ground still hard.  It has been three weeks since it crashed last, and is now flight ready after the repairs.
     I got 9 good trimming flights in with the 30" Speedster this morning.   I  started at  60 winds = 4 sec,  up to 160 winds = 8 sec - all hand winds - alas I bent the prop wire on the last flight - Speedster has no other damage ...   :)
I got it doing a small left hand circle flight and a couple of them landed right in front of me.   :D   Even those 8 sec flights seem to fly pretty fast and cover a fair amount of ground with this Speedster.

nine flights, four pics,  
motor = four strands 3/16" all strands 13.5 " long
prop hook to rear peg is a shade over 13.5"

#1     60 winds 4 sec  low slight left turn skimming the grass
#2     75 winds  5 sec  perfect slight left turn
#3     100 winds  6 sec , it went straight - bad launch - great recovery by the plane.
#4     I added a little bit of modeller's clay weight to the left wing tip
         100 winds  6 sec, perfect slight left turn, super soft landing,  did         not even bend the landing gear wires
#5     130 winds  7 sec   going left on downwind launch, finished high,  soft landing   Pic #1
#6     I added left rudder tab, zero on the elevator tabs
         140 winds  6 sec tight circle full 360 degrees
#7     I went less on the left rudder tab = the circle widened out a bit
         140 winds  6 sec,  perfect quick circle and lands right in front of
          me - no little bends in the landing gear wire  Pic #2
#8     160 winds  8 sec   perfect 7/8 circle - soft landing  Pic #3
#9     180 winds  7 sec    finished high coming back against the wind on
          a half circle flight, and came down hard.   Both landing gear had bent wire (I just bend it back real easy),  AND  the hard landing  bent the wire prop shaft.  That is two bent wire prop shafts (3/64"),   and one snapped off blade of the 9" high torque black plastic prop so far.   Pic #4

     We had to pack it up and go home at 11:00 AM now 73 deg F (88),  winds from the East at 9 mph gusting to 14 mph and 83% humidity.   Too much wind.
     I am running  out of  3"  wire prop shafts.   All in all, a good flight trimming session.   Time for stretch winds on the winding stooge next time.

Grabbed half an hour along at the aerodome before the light went and got the Walthew sort of trimmed.  

Fuzzy Video (https://www.flickr.com/photos/[email protected]/44134541972/in/album-72157698412359154/)

Not the best glide of the session but good enough that I'm not ashamed to share it.

So much for my hopes of high fifties AUW;  sixty five (65) grammes  with the wing 1/4" back from the front of the wing bearers.  How did that happen?   I might be able to bring that weight down a bit by tinkering with the wing position, but I'm not sure that I'll need to; even at that weight it's a very slow floaty glide.  

If you build this one you really do need a flat calm for trimming.  It'd also be a very good idea to take spare elastic bands with you, brightly coloured for preference, cos the wing will ping off (twice this evening) on a hard landing and you don't want to waste 10 or 15 minutes looking for a light brown laccy band in a field full of dry grass as the light is going. :)

Lurk - your Walthew looks promising. I would imagine the slower the glide on this one particularly - the better the glide, due to that heavily cambered wing.

Yesss, well trimmed lightweight gliders aren't supposed to.  However; untrimmed lightweight slow flying gliders, where setting the initial trim is a matter of pure guesswork, have this rather mmmm, unsettling habit of dropping the nose straight into the ground with consequent pingage of laccy bands. :)

Thank you, I think so too.  Given the floaty nature of the better trimming flights I can see OOS being a real risk with this one.  Better get the manufacturers plate rivetted onto the nose PDQ.

Lurker,  I admire your care and precision in making the ‘Walthew’ and also the excellent photographs accompanying the story and I hope it flies to your satisfaction but I fear that may not be the case. It is a type of model that I usually dislike, something especially designed for a beginner. They are usually too small to fly well and I shall never be convinced that a ‘Pistachio’ is easier to build than something bigger.  They often have some unusual features, presumably to make them ‘interesting’ but they usually spoil performance. The ‘Walthew’ has its strange mismatch of tailplane and wing sections and the preposterous parasol wing mount which adds nothing but weight and probably makes towing more difficult.
If I recall correctly (and I probably don’t!) I think you were hoping to bungee launch this glider.  If that is the case I strongly recommend that you fit an auto rudder.

Evening John,
If it flies at all I shall be well satisfied.  Deciding to build it was an entirely emotional decision and a present for my (inner) 10 year old self.  Logic, rationality and a sound aerodynamic engineering evaluation of the design didn't get within even very long hailing distance of the process.  I didn't mention bungee launching so you've no need to fear for your memory, but that is the intention because my ground crew are decidedly bolshy and there's no hope of ever getting them on the field for a tow launch.  It's going to be an interesting experiment.  
Lurk.

REARWIN SPEEDSTER 30" morning flights Fri Aug 24 2018

     Another great flying session - two in a row!
     Well, they did not mow the grass in the park yesterday,  and this morning was another great flying day - even better than yesterday  -  we got out there and set up and started flying at  8:00 AM,  knowing that the grass mowers start at 9:00 AM   -   54 deg F, Winds out of the South at 4 mph, gusting to 6 mph, 94 % humidity (tissue was wrinkled the whole time and thick dew on the grass).
     This has to be my best flying session with the Speedster, all trimmed up, ever, as the elegant Speedster magically flew her heart out.  All trimmed out with a 4 strand 3/16" motor, each strand is  19 1/2" long, motor, prop hook to rear peg is  13 1/2".     I just got in 9 glorious perfect flights running out the rubber,  nose block staying on, and all soft landings, prop staying on.  Started out with  375 winds for 14 seconds, and working my way up, to finishing with the last two flights of  600 winds each, and 33 seconds of flight each, just missing my all time record of 34 sec.   I got the Speedster doing tighter circles just by the rudder tab, and finished the last two flights with a  tight  3 1/2   circle flight (33 sec), and a tight 4 circle flight (33 sec).  First time ever getting in that many circles on one flight.
     I was really thinking about putting in an even longer motor    ::)  , but sure enough, four grass mowers showed up at 9:00 AM   ??? , so we packed up and went home, with the wind now  6 mph  from the South, gusting to 9 mph -  very flyable weather still ...
     And no damage to "Her Majesty".  I must remove that rubber motor now and stretch it out and fully examine it for nicks.
     Here is a preview - I will post the full flight report into Your Birds in Flight in General Forum on HPA later.

Glad to see your Speedster's back in the air Richard.


Prototyped a thrust-line adjuster for the VMC MfM series. This was sparked by a VMC Camel trimming/flying session with Jack Plane back in April.  My machine has some ugly great wedges on the NB to get a decent amount of right and down thrust but, apart from looking ugly, they don't give quite enough D/R thrust and larger wedges aren't really practical.

It's a shameless rip-off of the idea shown in Don Ross' book but the MfM series noseblock typically has a 12mm (nominal) square plug that goes into the fuselage and I wasn't sure I could make something of decent quality that small.  The only vaguely original feature is the four holes rather than one to hold the thrust adjustment plate. This lets me put the prop-shaft into any quadrant without the adjustment plate overlapping the noseplug edge.  I might move the holes a bit nearer the centre to reduce the risk of splitting.

The attachments show the brass work, it's a bit rough but for about an hour's work it'll do for a prototype. The main plate will sit on at least one, possibly two, 1/16" ply bearers.  As I said the brass-work only takes about an hour, but, unfortunately,  it does need a Dremel or similar to drill the holes.  I tried with a pin chuck to see if totally machine free fabrication was possible, but no dice.

Post by: OZPAF on August 24, 2018, 08:47:17 PM
Lurk I'm always a little concerned about the ability of the screw to hold the plate in it's required position under any sort of tension from the rubber motor.

However I would be glad to be proven wrong :)

Mike ZKAUD suggested that a similar design by Mark Braunlich should have a "lock" arm attached to the pawl. Mark's original and the sketch from Mike below.

Yes, it's a niggle at the back of my mind as well especially with such a tiny screw.  Providing it has sufficient purchase to hold for the duration of trimming that'll be good enough; the intention is that once a satisfactory trim is achieved the thrust adjuster plate can be araldited in place. Be fun finding out, eh?

Repaired my Bill Dean Skyray and took it out for some Jetcat fun with friends from the Alamo Escadrille.  Pretty breezy, but we had a good time anyway.  Through the morning I progressively took out a bunch of reflex from the boat-tail area - result was much improved launch behavior and much more altitude from the launches.  It still glides more like the space shuttle than a sailplane, but it's a lot of fun and it's flying much better.

   I did a little bit of flying today - nothing serious.   In the morning I did some hand wind test flights on the 30" Rearwin Speedster with a longer 3/16"  motor - four strands  22"  long  ( previous was  19 1/2" ).   It was way more windy than it said on the net, so I just did short power flights, and it seemed to be still trimmed out just right, even with a longer motor.
     Then in the afternoon, I checked the rubber motor sitting in the  17 1/2"  Air Camper, and it was rotten.   So then I made a 4 strand  6 1/2" motor of  1/8" rubber with a small Crocket Hook ( prop hook to rear peg is  7" ), and headed back out to the Cricket Wicket.  I had fun just making a lot of fast short flights on a beautiful sunny day - max flight was  12 seconds on 200 hand winds.   But it could really go on a power burst, and I could even aim it way up high, whereupon, it would run out the rubber way up, and glide back down to earth on a  45  degree angle flightpath. 
      The ground was very hard, and the long grass never grew back since they cut it last Friday, and I ended up bending, and straightening out, the prop shaft wire on both models, and flying again, after hard landings that had no effect on the infill planked noses of both models.  I could bend that prop wire back pretty much straight by hand, while it was still sitting in the black thrust button in the nose.

 Something I've been meaning to do for a while is add some detail to a Gasparin twin powered Bleriot XI I built some years ago. I got so far and then flew it and the extra detail was just forgotten.

 It had a recover last year and I even entered it in the Eddie Riding scale event a month back. It failed to make a 20s flight, 18s being the closest but it looked promising. So with a larger plastic prop fitted , slightly reduced power ( the climb out was a bit steep)  a new bottle of gas and the Flying Aces coming next weekend I thought I would add some of that missing detail. Tail struts where straightforward but the control column more difficult.

The circular 'steering wheel' was just cut from some good Q grain balsa and a control wire dome made from some blue foam. A bit of litho plate for the throttle quadrant and a balsa throttle lever and the whole thing is just 0.6g.

There's one instrument to make, Oil Pressure ? and a step plate in the fuselage but they'll have wait... hopefully not another 10 years  :-[

First pic shows the Bleriot missing its detail at the Eddie Riding

The next two show the simple construction and the final one after a coat of paint. I'll rub it down a bit when dry to remove the fuzz.

 ;D  worked on a astick model a mod of the blue ridge specioal for the stick fuselage chapter.

went fishing with my son and grandson. despite low water and half dead worms we each hauled in a TROUT .  a good time was had by all (except the Trout) ::) ::) ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D

a wiggling fish made the GK nervous but he hauled it in just fine. Progress is being made on all fronts.

Something I've been meaning to do for a while is add some detail to a Gasparin twin powered Bleriot XI I built some years ago...

Looks a treat Squirrel!  Vital statistics on model and motor?

Vital statistics on model and motor?

It's 1/12 scale, so 26" span powered by a Gasparin GM300 twin.

AUW is 5.6ozs so definitely an outdoor model. Fuselage is 1/16 sq Basswood with lots of added carbon strip up front with thread bracing at the rear for added strength. The undercarriage is ali tube and more carbon and the wheels - ply rims , brass hubs with fishing line spokes ( building the wheels was my one and only Aeromodeller article back in 2010 in the Steve Dorling days ). They look Ok but nothing of the finesse of George kandylakis's  method seen on this parish.

Covering is 'antique' Esaki Tissue

Pretty much lost patience with an Aerographics hunter build. Too much modification, too many mistakes, too many breakages... One last attempt, then I either source a scan of the kit sheets or a new kit if I can find one. Frustrating.

I did a bit more fiddly detail on the CO2 Bleriot XI this evening.

The oil pressure gauge was produced by scaling a photo I took on an iPhone in PS and printing a few copies onto photo paper. This was punched out with a 5mm punch and stuck with canopy glue to a piece of litho plate. I'll give the printed dial a quick dab of gloss varnish when its all dried.

To add to the detail I made up an oil pump from balsa and 22g wire, all this work is sure to mean it'll be too windy to fly it at the Flying Aces  8)

So that's the extensive instrumentation done !  cockpit looking slightly more like a cockpit now  ;)

Thanks to a member on here, I've spent a week scratch building corrected parts and parts I couldn't recover from the Hunter fuselage. The original cockpit area is in place and the keels have had new balsa scarf joined into the shaped original kit parts. Now to glue the formers on...

I was in two minds about this - whether to scratch build or buy. I actually hit the button on a purchase from the Sussex Model Centre but it didn't go through. I took this as karma and went with the scratch building over the expense. Karma kicked me straight in the nuts when the kit arrived from the UK with no notice. Ah well, it will come in handy when I do an RC version.

Now, where's my aliphatic resin... :D

     Hi Crabby!   You made me freshen up my motor supply for my 30"  Rearwin Speedster - the sun is supposed to come out this afternoon and the winds diminishing to  8 mph from W gusting to 12 mph,  by 5 PM.    Prop hook to rear peg is  13 3/4", and I have a 13 1/2", four strand of  3/16", motor in there, just tight enough for 200 hand finger winds, which gives me a  12  sec power run, and the prop block should drop out, or pop out, before or when, it hits the ground, hopefully.   Time to sneak into the Cricket Wicket grounds later ...

General faffing around.

Tidying up the workshop, Sanity checking part profiles for the next FF glider to go into the assembly hall, some time after Xmas I think - couple of other builds before it in the queue, and making up an adjustable ballast gadget for a bungee line.  

The ballast weight gadget came about because the Walthew MK II, with an AUW of about 65g, takes off like a scalded cat on a 1/8" bungee and I haven't got any thinner strip, nor have I had the chance to order any.  Last time I flew it I dumped 20 odd grammes of Blu-Tack in a poly bag and tied it to the line to see if I could get a less *ahem* vigorous launch.  It seemed to work and as the forecast for tomorrow is looking just about flyable here thought I'd conduct some slightly more controlled experiments to see whether this will allow me to safely launch even smaller models than the W MKII, such as the VMC Osprey which only tips the scales at 25-30 grammes (IIRC), off a 1/8" strip.

Squirrelnet: That Bleriot is just a beauty!

Personally I'm in the process of reconstructing/rescaling/whatchamacallit a Piper Cherokee. My model will have a wingspan around 39" (1000mm) when I'm done with the drawings, all done in CAD. For now I'm playing with thoughts of making a solid plug out of wood, waterproof it and then form balsa sheets around it to make kind of a monocoque fuselage, to make it as light/strong as possible. Time will show how I build it; this way, with a planks over formers or just with sticks and tissue. There are also "a few" other projects on the backburner, my "WWI era build" being one of them. This will not be a dull winter! :)

The Chipmunk is the 17" Guillows kit, the Beaver is the 30" Dumas kit, and the Otter is from the Pres Bruning plans on Paul Bradley's site and an awesome set of laser cut parts from Dave Cowell at Areowerks.

Today I converted a hand drill to a winder, so no more excuses, I need to find a suitable field with suitable non-breezy conditions and see if these will really fly.

let's start with i visited OWL'S HEAD TRANSPORT MUSEUM.  this place is located near camden maine and houses prehistorical airplanes and cars,.  it is very interesting and i tried flogging my book there . they liked it to a point and unfortunately for me they had all the books they can use.

SHAMELESS PLUG  GRANDPAW'S BIG BOOK OF AIRPLANES IS AVAILBLE FROM ME  via mail for $15.00 bucks all up in Canada you send Canadian funds and in USA its $15.00 US.  the difference is because of postal rates to usa

this would make a nice xmas gift for young children and grand kids to get them enthusiastic about airplanes and visiting museums.  if you are interested, send me a PM

i did substitute coffee sticks for the balsa struts, and landling gear, i replaced the plastic nose with two sheets of 1/4 balsa to bring weight forward. and i doubled upo the struts to provide proper support to the wings.  i've flown it in my basement and its almost there.  oh yeah a bigger prop is a must. oh yeah  top spars to both wings were added

Put back together a 20+ year-old Guillows Typhoon and took it out for some fun.  Moved the peg 2-1/2" forward, put in 2x17" loops 3/32" rubber turning a 6" Peck prop.  After a couple trim adjustments it was putting out steady 40-45 second flights on ~1300 turns.  Great fun till the wind changed and it smacked a chain-link fence across the parking lot...

Selected video at: https://www.youtube.com/watch?v=UMRGIFFT60g&feature=youtu.be (https://www.youtube.com/watch?v=UMRGIFFT60g&feature=youtu.be)

Flew the Tempest also to check out a 7-3/4" Igra prop.  Worked very well - put the model on the roof of a nearby store when wound to 5.5 oz-in!  The local security guards were very helpful, unlocked the ladder and retrieved the undamaged model from the roof.  Alas, as the gentleman on the roof handed the model off to the gentleman on the ladder, the wing and tail got crunched...  Oh well, it was about due to be re-covered anyway.  At least I have it back!

Lacey M-10 (Peck-Polymers' kit).  Like the Walthew this is unfinished business from a while back; started on the free plan that was dished out with Aeromodeller in late '76, never finished it.

A very productive day repairing a number of models starting with the Hacker Piper Cub that now has the new spat in place and just needs the yellow flash. This is a black with Yellow trim. Not a YHWM.
A Comet Avenger now has the new tailplane painted and repair tissue on the fuselage drying, the new Eaves Cougar peanut has competed painting while new wings and struts for the Avetek Tiger Moth are now finished ready for rigging, and the nose block of the Aerographics Moth Minor is now painted completing the paint as is the new nose block for the Ol Ironsides peanut. Clearly a lot of trim work now needs to be done on all of the above and a recovered Comper wing as well. All in all a very good day. The new compressor from Aldi is working well. The auto cut off is a nice feature as is the ability to regulate pressure easily.

I've spent the last week or so building Peter Rake's Mini Bluebird as a first foray into indoor RC for the winter season. I've changed one or two things to suit my building style, in particular the laminated wing and tail tips. Lot's of parts to cut out as I presume it was designed to be laser cut but it came together quite quickly after all the cutting was finished.

DH 60 GIPSY MOTH 30"    - Plan Sheets

       My big winter project will be another  30"  wingspan Jumbo rubber powered model.   It will be the Dumas DH 60  "GIPSY MOTH" biplane,  and will be flown, hopefully, for 15 second standard flights,  and for 30 second flights max, in the small confines of the Cricket Wicket  of Jackson Park.
     The two big  36" X 24" plan sheets were getting too much trouble moving around, so I made up two larger poster boards to fit them on,  from Ross Craft white foam board  3/16" X 30" X 20".    My "Mastercraft"   36"/100 cm  steel rule came in handy,  along with the square and  the cutting board.  I used a lot of clear scotch tape for the foam board pieces, and I used  "binder clips"  to hold the plan sheets to the Ross Craftboard.
     Now I can stare at, and read, and study, both plans at the same time, as they sit one above the other on the sofa chair (no complaints from Trapper ... lol    :)   ).
     Now I just need to photocopy those two big plan sheets at Staples, so I can scissor them up, and photocopy the laser cut balsa sheets, and instructions, and decals, and ...
     I found a couple of pretty good color schemes.  It will be traditional translucent tissue covering.

Breaking my,  "Only one build at a time." rule and it's all Mr. Fardell's fault.  Although if we're being picky about it; if I hadn't shown MrsLurker the film* of the ornithopters she wouldn't have wanted one in the first place.  :)

One Freebird. 

Stats: 
Weight without motor : 5.37g
Motor                        : 1.55g
Plan says typical weight quarter of an ounce (7g) so just squeaked under at 6.92g.

Max turns: Plan says 220 (lubed motor), using Ross' figures for 1/8" strip I get an 80% max of 240 so 200-220 should be perfectly safe.

No idea how well, or if, this will fly.  Going to have to wait for flat calm and dry weather to find out.  MrsL is adamant that it's not going to be flown indoors and it's her machine so she makes the rules.

Apologies for no flight pictures, but I did get 3 very nice trim flights on my version of a Phantom Flash.

Flight #1 approx 60 turns, Flight showed left turn slightly tail heavy, approx 4-5 seconds.
Flight #2 approx 70+ turns, Flight slight gentle initial climb then 20' or so dia left circle, no signs of stall. approx 5-6 seconds.
Flight #3 approx 80+ turns, gentle left turn climb then descending in fairly flat 20' circle, approx 6-7 seconds.

These were done in the street in front of my house so I don;t want to increase the winds beyond a 100 so that'll be it for now.

All flights were made with the balsa prop built per the plans. Thrust bearing is a .040" dia hole drilled thru an oak button, topped by a 3/32" plastic bead drilled with another .040" hole, and a brass washer.  Power is a single 8" loop of 3/32" FAI sport rubber.

Hey Lurk,
the Freebird does fly - and fairly well!

A couple of us built it about eight or nine years ago (might be more) - it was when Bernard (BG) was still in Germany.  Mine was a porker at nearly 9 grams (IIRC) as I used whatever wood that fell out of my junk box and it still flew - not an endurance flight by any means, tho.  Lasted about 15 flights, the final (literally!) being retrieved by a clubmates pooch.  Never got any photos...

Oh I have absolutely no doubts about the air-worthiness of the design, the issue is whether or not the particular incarnation as built by YT is up to snuff. :)

Canine retrieval suggests you were flying outside.  What sort of windspeeds could you get away with?  Did it have to be absolutely flat calm or could it cope with light airs?

The less wind the better.  I think it was dead calm for most of the flights, maybe max at 1 ms.  Back then we did have days where there was practically zero wind.  Mine seemed robust enough to be able to withstand a light breeze.

Just trying to decide which of my friends P-51s to try to build. One was in the first shuttle from England to Russia in the FAMOUS EAGLE SQUADRON, and the other lad flew on the second shuttle from I guess Italy to Russia. The First was in a B model and I think the later may have been flying the bubble canopy version. The one Col Chester Sluder flew is the one they copied for the one on display at Wright-Patterson ,home of the USAF Museum. He did visit the display before his death. Still have to pour over my books to see if I can locate any info on Lt Charles Brock and what his ship was named, the number etc. Two very nice GENTLEMEN who had Texas roots at some time. Yes Lt Brock could have been the poster boy for Texas A&M University
FYI I meet Lt Col Brock on Guam when we were serving there in 1972. I found him again in the book 1000 Destroyed.

I meet Col Sluder when he lived in the Air Force Village in San Antonio, Texas before I went to work there in 2002.

     This morning I made an extra stand for the 24" Fokker D7, to match the Dr1 Tripe.   I cut up a steel coat hangar, used a red felt sheet I bought at Michaels, and punched a hole in it with my leather punch, and used the old black tissue wooden picture frame as a base, into which I drilled a dead end hole for the hangar wire.
     Now these two Fokkers look good together.   "Curses" !!  -  I do not have a scale laminated wood prop for the tripe ...     :)

Sorted out the noseblock on the M-10 which I'd made a muck of through a mixture of poorly cut kit parts and rank stupidity on my part. And I'd say it was 80%+ stupidity.

Before and after pics.  Fixed up isn't 100%, but it's good enough that I'm not ashamed to admit it's my work.

Looking good Lurk!

For my part, I scored lots of edjut points for driving 40 mins each way this afternoon to slope soar in Hampshire, plus a very steep 20 minute climb, just to find that the forecast Easterly was in fact much more in the North-East!  Beacon Hill is evidently pretty good in a strong South-Easterly, but by dropping slightly down the shoulder to the south I was able to launch into just viable lift and practice landings over and over and over again!  :-[   Nonetheless, it was all very beautiful (if one ignored the growl of the A34 coming up from the valley) and my flask of tea was the main event!  :D

The famous Beacon Hill? What were you flying Jack?
For many years - it was always a 40min drive to my club field. Now it is only about 10mins away but full of restrictions and not the best for RC gliders as a consequence. At present we are restricted to 400'  - but hopefully we will have 1,000' in the near future. No FF allowed either - which is annoying.

Nice looking effort there Lurk. Your errors(?) are well hidden.

John, there appear to be quite a few 'Beacon Hills' (Sussex, Surrey, Somerset, etc), all presumably early warning systems given the long danger of Dutch, French or Spanish invasions.  This one (earlier use an Iron Age fort) is in Hampshire, with lots of restrictions on other activities like hang-gliding, droning and letting one's dog off the lead but (after protracted negotiations with the local Red Kites) open for slope soaring!   ;D

Was flying a Chris Foss 60" Middle Phase (two-aileron semi-symmetrical straight wing version) which I built earlier this year.  It is perfect for my current intermediate level and can handle most moderate to high wind conditions, but I've recently bought an all-wood Quark 2m short kit from Ireland, designed by Fred Marie as a 'slow' aerobatic with an almost fully-symmetrical wing (see last photo below), which I need to find time to build later in the winter.  Here's lovely footage of Danny Chapman flying his off Kilkee Cliffs: https://www.youtube.com/watch?time_continue=6&v=R_Inobt6fgY (https://www.youtube.com/watch?time_continue=6&v=R_Inobt6fgY)

Got one short test flight of my bbPusher yesterday.  The balance is great, it was a nice level flight with about 60-70 winds, but dead straight! I had put a couple grams of weight on the left wing tip to counteract a sharp right turn on a previous test. I was using the street in front of our house which of course then decided to have enough traffic to stop the test. I think rather than reduce the tip weight I will warp in a touch of right rudder to get it to turn.

The right turn tendency is due to the fact that I made a reverse pitch pusher prop so I can use my winder normally on it. But how do folks hold stick fuselages in a stooge?

I went through all my modeling mags and filed what I wanted and canned the rest. It is noteworthy how little of the mags actually pertains to you. Very little grain and loads of chaff. But I found my copy of "Model Airplane Design by Charles Hampson Grant! I also took the pill and euthanized a bunch of models last week. Then I took stock of all the "S" I thought I had to have, and what little of it I actually use. You don't need 7/8 of the crap you "think" you need...but that's a process as well. There is a lot of pruning to do in a life before you can whittle down to the essential "immortal diamond."

Slightly more satisfactory results with tissue today.  Got the air intake blended in to the lower nose chevron and, to my mind, a quite satisfactory tyre and hub finish using tissue.  A bit of a fiddle winding the tissue strip around the wire and I don't suppose it'll stand too many ROG flights before wearing through to the wire, but the wire is far too thin for any of the heat-shrink tubing I have to hand.   ROG? Hah! I should be so lucky.

I flew my Bradley Termite motorglider (a foam adaptation I did a few years ago) in absolutely calm conditions this morning, (only16F out) to test out a new folding prop rig I made. I had just adapted my EMP 1822 motor to fit the new prop by pressing out the old motor shaft and pressing in a new longer one.

I did some glide-to-dive tests in the still air to see how it had affected CG. It seemed like I could move it aft a smidge, as the glider recovered quickly from a dive. The new folding prop and spinner weigh more than the old fixed prop, and are further forward.

Title: Re: What Did You Do Airplane Wise Today?
Post by: vtdiy on December 06, 2018, 08:42:47 AM
Hi Yak 52, It's a Ralph Bradley design (from the Parmodels website) originally intended for balsa construction.

I used 1/4" fanfold blue foam (stripped of the plastic covering) and extended the nose longer because with current light weight gear and construction, I knew I'd otherwise give myself a CG location problem compared to the heavier brushed original. The airfoil is just a 1/4" thick sanded flat bottom type in foam -- by eye and hand -- just like the balsa version shown on the plans.

Polyhedral joints were reinforced with a strip of paper soaked in water diluted Titebond II carpenter's glue. A 2" wide paper strip was run along the leading edge, and wraps around it.

A 1" wide strip of packing tape was run along the wing underside. Bare foam was filled with dilute lightweight spackle with a little Minwax Polycrylic mixed in, and a little talcum powder added. Finish is Apple Barrel craft acrylic paint, I chose bright light blue to minimize the number of cover coats on the blue foam, but added orange tips to help visibility, and the underside and rear fuselage are very dark navy blue to help with orientation.

The motor is a EMP C 1822 type, and the battery is a zippy 2S 350 mah. AUW when built was about 4-1/2 oz. It went through one major crash and repair, and now sports a folding propeller -- AUW is now 5 oz. Wing area is one square foot.


Title: Re: What Did You Do Airplane Wise Today?
Post by: vtdiy on December 06, 2018, 10:40:23 AM
This morning, a little warmer temp 30F and it looked like calm (though turned out to be puffy with calms) so I took out another old and formerly beat up, but recently resuscitated foam build, my "hacksaw special"  P-40. It flies nicely in my tree lined space and has plenty of power, but still oddly wants to dive fairly steeply power off. I had just added more downthrust, hoping that would cure it, but it didn't seem to help much.

I'm now thinking the fairly crude undercambered airfoil is to blame. I think I'll thin the trailing edge by tapering it up towards the upper surface to give it a slight degree of reflex. Experiments I did recently with flat foam planks show that undercambered plate foils really want to bunt under, and I'm thinking this is what I'm seeing in the glide. We'll see. I love experimenting with this stuff!

I suspect that the CG is a bit too far forward and or you need more longitudinal dihedral. However this will probably lead to more down thrust being required.

3) this am i started watching AIRFORCE (1943) on of the best airplane movies of all time. lots of B-17 D action and the rootinist tootenst combat scene at the end.
4) at the xmas party i corralled the minister of transport  to get a meeting.  highway construction can screw up streams that the roads cross to to bridge, highway design. i want to fix that.  its not airplanes but you all know how much i luv TROUT!  if there are any fishermen, hunters, nature lovers etc., among you i will happily email you my report,. if you see similar stuff in your country you can use this report as a model to complain to your public officials. global warming is a fact and wildlife need all the friends they can get.

Something a little different. I have been developing a Super Capacitor powered  outdoor FF for a contact in India. He does not have access to balsa so it is will be foam ( plate foam), and popsicle stick for reinforcement. The prototype is all 3mm Depron with a bit of hard 1.5mm balsa. 16" WS and weighs 11gms without trim ballast. Expected weight with motor, capacitor and micro switch - approx. 21gms. Wing loading approx. 0.4gms/sq inch.

It must have been a long tense building session.
Thanks vtdiy - It's an interesting concept and ideally suited for my contact as specialist modelling items - such as rubber are difficult and expensive to get. some of the fellows flying these models are achieving 1min plus flights on less than 20secs of charge time.

Today's airplane stuff:

I started to build David Scigliano's Piper Cub Bostonian. I'm enjoying that a lot more than the Comet Hurricane I started. It's very nicely designed, nice proportions, and easy to build, the structure is light but strong. I'm really happy with how this is going.

OZPAF do you make your own super capacitor circuit? I'm kind of interested in what that's like.
vtdiy Actually it's very simple a Supercapacitor, wired either through a small switch(recommended)or direct to the motor. Charging is via 2-3 AA batteries.
Here are a couple of interesting links showing their potential

Thanks all. :)

Good luck with that Josh. I noticed that it is definitely not a model to be handled by shaky geriatrics :) Mime actors would do well.
It must have been a long tense building session.

Definitely not for the faint of heart. I've actually built two of them this size. The fuselage and tail of the first one were destroyed in transport back from the first flying session. Faulty packing on my part :o Anyway, I built a second that is much better than the first one anyway (still have both of these monster 60"+ wings though, and that's the hardest part of the entire plane to build). If I remember correctly, the entire build for both airframes took two weeks, after which I help Hope build her 42" version in a single week. Quite a wild ride for sure!

I received this envelope in the mail today, 86 years too late!

Well too late to attend anyway..... Just chance that I saw it for sale on Ebay -- I'm not a collector of memorabilia, but I've spent much time in Louisiana (my mother's side of the family is from New Orleans) and I'm a great fan of Weddell-Williams planes.... it was just a few dollars, and I just had to have it.

I wouldn't have minded attending "The New Orleans Carnival of the Air", in 1932.

This is a build that I have been picking at for a couple of months, work has been very busy, with it taking all of creative energies...

I had being hanging my nose over this simply charming Guillows kit for a while that was for sale by Nigel Monk.  Eventually we agreed a price.  I haven’t used the kit but copied the plan, and cut the parts out from there.

There are no mods other than provision for a removeable nose block and a few extra gussets.

What you see in the pictures comes in at a smidge less than 9g.

You are right of course, but it has grown out of unfortunate overlaps and suitability problems. E.g.. I have a 610mm carriage vinyl cutter in the bedroom for somewhere dry and dust free!

The Birdkit site is certainly different Richard. Amazing how ell those large RC Ornithopters fly - and how much noise the gearboxes make.

The Osprey glider is a nice looking little model.

Amazing how many nice aircraft came out of that period in America in the 30's. It should be a nice flying model - no too much structure there apart from those wheel pants.

Merry Christmas.

I picked up this Andrews Aeromaster a few months ago, and installed an HB61PDP 2 stroker in it, and finally had a decent enough day to get the maiden in on it. It tracked nicely down the runway with a touch of right rudder, and lifted off smoothly. It only needed a touch of down elevator, and right aileron for a straight and level flight. I put in a 14 oz tank in it, and just cruising at half throttle, managed a 13 min flight. I'm going to really enjoy this one. Here are a few pics- Dean ;D

Mandrake and Bloodroot decide to make some extra money in their off time, at the upcoming Essex County Fair, as "Barnstormers", after reading up on the HPA website.   They team up with Erst Udet who was looking for partners,  and his Fokker Dr.1 Triplane, and practise some daredevil stunts.

I got three of my kit test builds completed. Hope to get a bit of test flying in tomorrow.
The first is my 24 inch Cessna Cr3 racer for rubber power. This is all balsa with printed tissue. Weight as is is 55g. Prop is a from my 10.5 inch De Loach Prop kit with ply core/hub.

The second is my B57-B Canberra in Viet Nam Era night scheme. This one weighs 30g and is 18" span. Built-up structure and printed tissue covering.

So you have modelshop locally (I assume) yak and that is nice.  Are you able to say where because some may like a fix.

Must admit there was a time when rain sleet snow and even quite high winds were not a deterrent when I flew Radio almost exclusively but now having advanced the years and reverted back to free flight hostile conditions are a bit of a deterrent.  Well done then Monique.  Keeping your balance launching those models is not easy in good conditions.

David, I'm about 25 minutes from Inwood Models in Huntingdon. I'm also a similar distance from Geoff Stubbs in Oundle who has sadly been closed for about a year now due to ill health. Geoff is still about though and welcomes a chin wag although unfortunately his eyesight doesn't permit him to build or fly any more.

Finished the two-day assembly of my Armsoar GO Mini 1m DLG.  It is full-house (i.e. with variable wing-camber flapperons and other cunning flight-mode mixes and whatnot) but only 60% of the weight of a normal 1.5m DLG - so I'm hoping my back will cope with the reduced rotational strain on launch.

I'm also hoping that one day everything will just click and I'll be able to soar from thermal to thermal with complete nonchalance!

In the meantime, relatively still air is forecast for tomorrow's Christmas maiden... err... the other one!  :D

Ja, me too. Though the way I throw my left leg slips out backwards and I end up on my face and elbow (tx arm) with the glider disappearing behind me...

The CX5 is a different beast hey. Still getting used to it, but then, I wasn't used to the NXT yet either. Flying them is one thing, but learning how to read the air with them and then use that 'read' is a whole different thing altogether. The CX5 is much quieter than the NXT on launch and definitely penetrates sink better, but the NXT cores and signals lift better. But, that could also be more to me having more time on the NXT than the CX5.

I only bought the CX5 as the NXT was totaled in a midair at a contest. I couldn't be without a DLG (hooked ;) ) and the CX came along at the right time to fill the gap while I worked on repairing the NXT, which took a looong time. I was about 10m up and a guy launched right through me. His wing went through the rudder and fin shredding them, then onto the boom and stab mount, shredding those and the ground impact broke the right wing completely in three places. He still said afterwards that he saw me there, but launched anyway...  ??? Today was the first time the NXT's flown since the repairs. I've added about 25g in repairs so it'll be my windy model.

That looks nice. Glad you said 'assembly' and not 'build'  ;D

When I first started launching DLG's I tried the 'Munier' rotation method and kept straining my back. I kept focusing too much on the footwork instead of what felt comfortable. Now I do a lazy 360° ish type thing with all the power coming from the last 90° and the extension of the arm with a bit of wrist flick. I can launch all day without feeling it, topping out above 80m on really, really good launches  8)

This morning's GO Mini maiden was lekker! ;D

Light and very easy to launch (with no sign of back-strain, yay!) to a good height for initial dead-air trims, and needed very little fine-tuning through the various flight-modes.  No idea what actual heights, but guessing at 40-45m without even trying.  I might in due course fit a recording-altimeter just to see what's achievable with practice, or maybe even swap out the tiny Lemon RX for their (almost as tiny) telemetry version.  The 1s 300mAh Lipo looks like its good for maybe 45-60mins.

You're right Monz about working out one own's launch-technique.  I've watched Pierre's vids on his 'light-but-fast' rotation, and compared this to Marcus Stent's heavier 'power-launch'(for example):  they are very different body-types and ages, and I'm certainly a lot closer to Marcus in both respects than to Pierre!

It would be useful to rock up at one of the F3K meets in 2019 for a bit of expert observation and advice...

I shall have to get saving.... The Smile from Hyperflight looks lovely but very expensive

In the meantime Santa brought me this for Xmas - Double action trigger airbrush and compressor ;D. A nice little kit with 3 different needles and 3 different cup sizes. Initial test with acrylic ink show it has a nice even spray pattern too. The first victim will be the PZL Wilga I'm building

Lovely Christmas pressie you've got there Chris.

Re DLG, if you're after a relatively modern 1.5m mouldie but for less money than a new one and the cost of all the gubbins, then I might be selling my Blaster 3.  I bought it from Neil at Hyperflight and put it together a couple of years ago with four KST servos but it has hardly been flown since then, as my back was giving me grief previously - and hence my decision to stick to the lighter 1m size, i.e. the GO Mini, for the time being.

PM me if interested.

Oh I see - did not realise Inwod were still there as not been that way for many a year.  That is good.  They had good wood then in particular.  But SLEC are a short jaunt away for me now.   I remember George from quite a way back and am pleased he is still about even his activity is limited.  Is the shop stil there?  Wonder if I could interest the National Trust?

How do you find the performance compared to 1.5m models, albeit in still cold air


Difficult to tell Chris, as my back was giving me gyp eighteen months ago when I got the Blaster3 airborne, and so didn't get to put in much stick time, certainly not enough to get on top of properly trimming the different flight modes in different conditions, etc.

On first acquaintance however the GO Mini feels very natural - easy to launch, confident to fly, and in today's brief session before lunch I worked out that its best to fly reasonably fast towards me then hit the brakes for an assured nose-catch, rather than piddle along and have the thing drop short onto the ground!  It took very few clicks to iron out a slight tendency to bank left (an incipient wing warp or other asymmetry somewhere?), then I quickly got the hang of trimming elevator for each of speed, cruise and float modes.  Best time today was 1:04 in almost dead air in float-mode, off a launch of maybe 35-40m.  All this based on the instructions recommended camber and travel settings for each flight-mode, with my usual 15% expo (just to neutralise the servo-horn's mechanical advantage around centre-sticks).  The model seems happiest with zero differential, but I need to play with this a bit more.  CG is currently mid-way in Thomas' suggested range between normal and turbulent conditions.  (He generally prefers a slightly forward CG as he reckons this reduces pilot workload when one should be concentrating on finding lift etc.)

The GO Mini tops the scales at 146g, which is a bit heavier than the Hawk's 120g (the other contemporary 1m DLG with full flight-mode capability; I don't know what the Strike is supposed to weigh) but has a wide chord similar to a 1.5m ship, and its slight porkiness should theoretically allow greater launch heights?  At 260g the Blaster3 is about 80% heavier than this (as would be other DLGs in the 1.5m size) thus my aforementioned back problem!

The only practical issue for me with a 1m DLG is its slightly smaller size when higher up, which would make attitude differences (or ill-advised over-controlling) in active air harder to spot.  But I'm working on the theory that nailing elevator trims for each of the flight modes when lower down - and practicing keeping my paws off the sticks when working through active space - should hopefully enable me to concentrate on what the air is doing in terms of lift and sink rather than what I'm doing (wrong) with the model.

great thoughts Jon. I'm sure some of my best flights have been with the least input. The number of times I have over controlled my way out of thermal !!!

  It took very few clicks to iron out a slight tendency to bank left (an incipient wing warp or other asymmetry somewhere?)

Jon, did you balance the weight of the throwing peg laterally with weight in the other wing? This might be the cause of the trim difference although if I recall correctly the common wisdom is that a few clicks of trim is better than more weight and inertia anyway so I wouldn't worry about it.

Jon


Title: Re: What Did You Do Airplane Wise Today?
Post by: Jack Plane on December 26, 2018, 04:29:43 PM
Jon, good point... I didn't think to check the static lateral balance.  However I've just finished amending my settings 'spreadsheet' (now v.1.1 after initial trim sessions :D ) and decided to eyeball the wing:  there IS in fact an in-built warp!  :o  Whether this happened in production or worked itself in later (box hanging around on a shelf over the very hot summer?) I don't know, but the warpage of wash-in on the right wing and wash-out on the left one tallies exactly with my need to add 10 clicks of right aileron trim (i.e. 1.0mm either way) in all flight modes.

Tomorrow's forecast looking excellent for more dead-air familiarisation with the GO Mini, plus maybe see how it responds to any weak thermals about...?  Might also take the Blaster3 with me and see (once my back is warmed up) how that compares  :)

I built a birdkits.com Bluebird onithopter.  Took all of 25 minutes including time to let the glue dry. First airplane related building since July when I started working on a doll house for my great niece’s Christmas present. Glad it’s done!  It was a real pain but she really loves it so it’s all good!

Out again today, this time in weak sunshine around lunchtime, and with a HK recording altimeter in the nose.  Best flight in almost still-air was 1:48.  Obviously over-estimated my previous launch heights, as the altimeter showed the majority today were around 35m (140ft) with the highest at 38m.  A few more tweaks (increase the up-elevator on rotation from 1.0mm to 1.5mm?) and work on my technique and strength over time, and I'd like to be hitting 40m or so.  But the best news is that my back - having had a hot bath and then done stretching exercises before heading out - had no problems with the current strain!  :)

I do envy you being able to DL a glider ... I've fancied a go for years but I'm sure my shoulder problem would flare up.
I think it's way back to the 70s when I flew gliders over the Christmas period ... bungee launching the old Amigo II.
The times sound good from that height. I think my bungee was 150 metres in total and I was happy with 4 min flights in 'normal' air.

I think my peanut Pietenpol is getting close to 14 years old now. I never have got what I hoped from it ... I used to have some Tan2 rubber that suited it well and gave the odd 30 second plus flight but nothing more than that.
After all this time I thought I would try a CO2 conversion instead of the model just sitting in a box.

At the moment I have just cut away the underneath of the nose to try the motor and tank in place ... and removed the rubber related components.
I took the wheels off and tried a test glide with everything loosely in place, bar the propeller. It's a bit on the weighty side but the glide wasn't bad.
With this in mind, I will try the small 1/36 scale prop first so that the balance isn't affected too much ..... I'm expecting a powered glide at most probably.
The props in front of the model were the size I thought would be suitable, but it will probably be a 'Goldilocks' situation needing something in between.

The second shot shows a 'GM63' sized prop for comparison ... it's quite a small model as I used the 13" span for peanut rather than using the fuselage length that would have allowed a larger model.

Post by: FreeFlightModeller on December 29, 2018, 10:18:44 AM
Thanks Vtdiy .... I based the model on a Tasmanian build. I contacted the builder and was surprised to find that my model flew before the actual aircraft.
It's a reduced version of David Collins 28" plan .. I built it at that size too. I still feel that there is another one in me to build. I do not do RC really .... but I fancy an RC version.

Love the Piet, FFM, I also have the Ariel - Piet biplane conversion plans (full size). I ended up starting to build a Ragwing Heath Parasol UL.

I have been thinking of going backwards in time in R/C myself lately with a rudder-only, and just bang-bang rudder, escapement style. Something like the Piet or Heath might be fun that way.

In fact, apropos this thread (and limited R/C), yesterday I resurrected, and flew a ten year old "Smiley" I built using the guts from an AeroAces Jetset twin and dollarTree foam. These JetSet planes were throttle-only twins, where differential throttle controlled the plane's direction. No moving tail surfaces. They were quite ugly, with weird colors and stickers all over them, and not always the best fliers. Planes were in the 20 gram range, and could only be flown about 100 feet away.

But the gear and motors were very light for the time (pre-Hobbyzone bricks), and all kinds of small and light models were built using the cannibalized gear from the low-cost originals. The last few AA JetSet models I bought cost $15 (with TX) in closeouts at Walmart. We had a ton of fun with that gear in all sorts of small models.

Flying the old Smiley again brought that all back. It was in some ways more fun than today's full house proportional in the small models I usually build for my home field. It was weird extending the transmitter antenna again (27 Mhz) and I forgot once, until I realized at 20 feet I'd run out of range!

Smiley below, as flown yeaterday after 10 years. Span= 12"

Jon,
I've not really been working at an acceptable level for about a decade now ... so modelling has been a very guilty pleasure.
I have got a lot of stuff 'kitted' and ready for the day. Work at last is starting to work! ... so I hope to lift the modelling side too. I do seem to work better when busy, so fingers crossed...

Two of my favourite events are the Indoor Scale Nats and Peterborough Flying Aces ... I judge at the PFA, so I'm unable to fly. I've not been flying at the Nats .... missing it so hopefully will return before too long.

Pete - The pics are very interesting many look contemporary WW1 but the Fokker D7 is puzzling as the engine looks very different. Is it a modern'ish' replica meaning the photos are from various dates  ? or a re engined original example done around the time ? The captions are great .

I know some Fokker DVIIs ended up in America and were used for Hollywood film work in the '20s. Perhaps it's one of those? One of the Bill Hannan books has a good article on the various movie Fokkers.

Mike- I noticed that US SE5 too. The nosed over shot gives a great view for scale documentation!

Sharp observations, gents! The D VII with the wavy stripe on the side is probably the "movie" Fokker that the Walt Mooney plan is based on; from Hell's Angels. Some of the other types look like they may be from a more modern timeframe as well. Maybe SDASM can offer some insight into those picture albums.

Don't know if this counts as 'airplane', but we did a bit more model rocketry today!  ;D

I'd bought the kid an Estes complete kit for Christmas (0.5m tall rocket, launch-pad, launch-controller and a couple of A class motors) plus half a dozen B and C class motors.  They're all 18mm diameter:  A class is really just a test motor and doesn't get very high, B class is much better, and C class is really "sick" (as the youth of today are fond of saying).  In each class, there's a range of delays after the main motor burn before the top charge is set off to force the nose-cone out for the parachute to deploy.

Video here of a B class launch yesterday (about 90m or 300ft):  https://photos.app.goo.gl/mQtaVtTqU5wBBJLD8 (https://photos.app.goo.gl/mQtaVtTqU5wBBJLD8)

So today, before we headed out to our local field, I converted the nose-cone to take a 1s lip and a Hobby-King recording altimeter - the C class motor broke the 500' barrier!  :o

Also, before anyone rushes in to say "what about the new 400ft limit?" for unmanned model aircraft, all I can say is that I checked the website of the UKRA (rocketry governing organisation over here) and couldn't find anything specific to this.  There are plenty of sensible safety rules and stuff about the minimum field size and minimum distance from launch-pad to controller-operator for different size motors, but no mention of the 400ft limit.  Usefully also is the fact that insurance is covered by our BMFA membership.

Next up is to get a kit for a 1m tall rocket (so he can at least build the thing) which will be able to take a more powerful D class motor of 24mm diameter... so "sicker" still!  8)

That's a great way to keep warm , and you were both having fun. As for the height limit I believe that the BMFA and the other associations have secured an exemption to the 400' height limit for all models under 7.5kg(?) including rockets(I believe) but not multi rotors.
You have a sensible people looking after your interests over there .
Happy New Year and here's to more rockets in the future or whatever is regarded as "Sick" in the aviation area. :)

We lost the rocket!  :'(  The secondary charge (the one that is designed, after the main thrust charge is spent and after a slight delay, to pop the nose-cone out to deploy the parachute) failed to go off!  The thing is too small to spot high in the sky after the glow of the burn and the smoke-trail is spent, and we searched the adjoining fields until it got too cold and dark.  Later, after a bit more research, the Kid informed me that the motors don't work reliably when its very cold - and it was very close to freezing!  Ne'er mind, we've now got a serious-looking 1m jobbie which takes even bigger motors on order from Apogee the US  ;D

Meant to add that I also spent half an hour before this working on my 1.5m DLG launch-technique.  Here the final launch of a couple of dozen in the session, after I was proper warmed-up:  https://photos.app.goo.gl/2UU8quwHuM4ggD1G6 (https://photos.app.goo.gl/2UU8quwHuM4ggD1G6)

Rocketry! One of my other hobbies. Looks like you had fun Jack till the rocket disappeared. Losing a rocket isn't fun.  By the way I've flown Estes motors at 15F (-9C) without any issues.

My rockets are a bit larger ;D

The Sledgehammer on its way. The motor for that flight was a J375-10.  Check out the mach diamonds in the thrust flame...

The big boys!  So, does that mean that the initial thrust flame is exceeding the speed of sound?

Losing the rocket wasn't fun: even if it was only an inexpensive beginner's one, lost with it was my spare HobbyKing recording altimeter.

But at least we learnt that sometimes other things go wrong apart from the motor not firing because the starter wires weren't pushed in far enough or were shorting.

Ah yes, we've got one of those on order...  ;D

In other news... I was out practicing DLG launches again this arvo and luckily decided to jog around the field perimeter to warm up a bit first, when I found the rocket!  It was just lying there on the bridleway not far downwind of our launch position!  The parachute had clearly deployed in the air, so I don't know why we didn't see it come down - maybe because we were so focussed on the upwind area of sky and it doubled back as a mere spec at 500ft behind our heads before the final charge popped the nose-cone off?

Glad you found the rocket Jack!

The 1:10 Saturn V was an impressive project for sure. Lots of money in motors for it.  Most impressive amatuer rocketry flight from last year? 3 stage high power rocket to 175,000ft! 53.34 kilometers 3.5 mach! Curvature of the earth!

True. And yet the possibility of a fly away is one of Free Flights charms (frustrations).

OZPAF do you make your own super capacitor circuit? I'm kind of interested in what that's like.
vtdiy Actually it's very simple a Supercapacitor, wired either through a small switch(recommended)or direct to the motor. Charging is via 2-3 AA batteries.

Hi John, do you have a circuit diagram for this at all please?
I presume the switch is used to stop the motor running off the charger battery?

Thanks :)


Lovely Wicko Mike, what version is this? I've often thought it would make a nice Frog Junior style model as it's very pretty for a simple boxy fuselage.

I spent a lovely morning with Jon (Jack Plane) flying and talking DLG's. I got into DLG in 2002/3 and homebuilt a few models before they were readily available. The final version of  my Mark Dreala SuperGee still gets a regular airing   ... Jon me showed how far the discipline has come in the intervening years.  I learnt a lot and realise I have a lot more to learn...  ;D

Here's a couple of Jon in action with a Blaster 3

Cheers Chris

For the less than fully initiated, the first shot wasn't that good a launch.  The DLG should really be released closer to the horizontal just at it leaves the hand at the end of the body-rotation, then almost immediately rotate up to 80o, which the second photo (hand and model) shows much better.

This will be the prototype GM-1 with the Cirrus Minor engine, 26" span from an A. J. Groom plan off Outerzone.  It's very much a simplified scale representation of the aircraft, but it looks like it should make a good flyer.

Jon, this is a better youtube video for super capacitors in planes, and explains the basics.

https://www.youtube.com/watch?v=vF1mOyZc1lk

Yes, the motors are just directly connected to the capacitor. The switch between them is optional, but does allow charging with the motor stationary. The very cheapest RTF versions don't use a switch, they charge the capacitor with the motor running -- it spins up as it charges!

The charger can be as simple as two alkaline cells in series -- that's shown in the video with a homemade charger using a connector made with paperclips. Also in the video is a sophisticated charger with digital readout. Voltages and charge rates are discussed also.

I bought some capacitors and micro sized slide switches on ebay, but haven't built anything for it yet. But very interested if you do.




Title: Re: What Did You Do Airplane Wise Today?
Post by: Yak 52 on January 08, 2019, 07:22:54 AM
Thanks Vtdiy - I actually found this video and made up some circuits, it was simpler than I expected :)

To test it I used a 2.7V 1F cap and a 6mm motor from a servo. I added a 3.3R resistor to limit the charge current and charged it off a 9V battery (well my FET Timer zapper actually.) The cap actually took as much as 3.4V but I may have shortened it's life somewhat, I will make a holder for two AA's. You would use a higher Farad cap in an actual model in most cases I think. like 10-25F, but the circuit as shown works. It would save some weight to put the resistor on the charger rather than the model.

I had a small capacitor toy plane back in the day which had a trigger grip charger that launched the plane. It had a switch that removed the motor from the circuit while charging. I played around using the bits on my own balsa versions too.

Post by: vtdiy on January 08, 2019, 07:03:25 PM
Thanks for the info about the resistor, Jon. I'll try that with maybe 3 Nimh's when I get around to trying those. I bought 10 F caps on ebay.

Today, airplane-wise, I flew a dozen year old resurrected Airhogs Jetset toy jet around the backyard, dodging the fruit trees. It was great fun to be back to super simple crude R/C. Differential thrust the only control and maybe a 60 foot range on 27 mhz. I had to raise the transmitter over my head occasionally at the limit. It was a perfect calm day.

Then I took out the rubber powered Caudron, with a 9-13 prop. Still couldn't get it to climb, trimmed the prop to 8", and even tried a short length of 3/16: rubber. As luck would have it, it hit the single ice covered snowplow drift in the field, and knocked the pigtail thrust bearing off the stick. Took it back to the house and I glued it back on temporarily with some quick setting epoxy, and this time I decided to add a little upthrust.

Wow, what a difference! Just fifty turns of the 3/16" put it into a couple of 30 foot right hand circles ten feet high. I tried 100 turns then, but it power stalled, so I'm happily able to go back down in size for the rubber.

I tried a short 1/8" loop with 50 turns and a little added nose weight, and there was still plenty of climb. It was getting dark and I couldn't try it, but I'm wondering if I can even go to 3/32".

I've flown this model for short trim hops maybe 25 times, and today was the first time I saw it climb. Guess I overdid it on the initial built in downthrust!

Did a quick paper mockup of a new nocal that I drew up before the holidays. It's a 1965 Mooney M20C.   It's just to check out how things will look  (check proportions, surface areas, etc.).  The stick and tissue build will be covered using orange and white tissue, with gold accent (metallic flavored art pen).  I built a Mooney Mite nocal many years ago; it was a pretty good flyer, so this with similar layout should be just fine.

So completely frustrated and bored that I can't risk the Doodlebug yet that I dug out my Phantom Flash for a spin in the front yard.

OOPS!! Of course a gust of breeze hit just as it was released for the second flight. Luckily only had about 100 winds on it.

Thanks - it's got good proportions, but the weight is starting to add up with wheel pants, struts, fairings etc.  Bones are about 29g so far.  Ideally it'd come in about 40g without the motor, but I'm thinking it'll probably be somewhere between 50 and 60g less rubber.

Hi All,
I have finally completed my Mr Mulligan Kit. The kit is laser cut and the tissue is Japanese tissue that has been printed with water and thinners proof pigment. In this case I chose to do a post race "dirty birdy" colour scheme with soot and oil stains down the side and bottom. The model weighs 46g as is. Plan to use a 9.5 inch prop and 15g of rubber (6 strands of 1/8th). Will do test flights when the grass is long (UC is knock off but still prefer to fly over long grass anyway).

...

I've just finished a new zapper...


They'll be calling you Taser Jon next!  ;D

It is supposed to be fun and I'm sure it will be when everything eventually 'clicks' but I'm really more enchanted with the slope soaring and DLG thermal side of things, which I find more instinctive.  I flew virtually no RC power last year, partly because of FF scale stuff and a bit of sloping, but really because work and personal circumstances wrecked the summer.  My four-stroke Acrowot didn't get much airing and I was almost thinking of deep-sixing the whole RC power thing, but later reckoned that if I got myself an ARTF electric sports-acrobat of decent size and penetration (not a little foam thing that'd get flicked around our hilltop site) then I'll have no excuse for getting in the stick-time.

In terms of interest, it'll always come well behind 'proper' aero-modelling and sloping (and I also want to get to some DLG events this year), but the patch is only five minutes from my home and I do enjoy the craic with club members.  And... err.. the goal of going for the 'B' Certificate seems to have become a bit of a motivator...  :o

In the meantime, I was deep in my annual accounts just before lunch today when I suddenly got a message from a club chum to meet him up the hill (also quite close to home).  Cracking weather, NNW wind right up the bowl, and fab sunshine!  We only stopped when our fingers ceased working in the cold!

Very nice Mr Mulligan BG - suitably dirty.

Jon your zapper looks like it would be suitable for super cap charging with a lower voltage battery or step down circuit.

Good way to go Jack - a bit of slope flying with mates is very relaxing. I have done a bit but far more Thermal and F3B, but always enjoyed my rare chances to fly on the slope. Nice old Chris Foss design - I see you are a Chris Foss Fan.

Don't let life get in the way of necessary flight relaxation.

Yes, It's the only way to ensure good behavior at a Bushfield flying session.

Totally get you about the power vs gliding priorities - I'm much the same. I think that gliding at least teaches you to put a model exactly where you want it, which must help. I've been thinking about getting some certificates since with new regulation it might be needed to fly at all in some places?

John, yes you could charge a supercap with it - but I think I would add an LED to show you it was charging and possibly a current limiting resistor in the circuit. (The Peterborough Timer has quite a large resistor in the circuit so very little current flows in the 'zap'.) Details of Chris's mod are here:

http://peterboroughmfc.org/technical-articles2018/Zapper-Chris.htm

Mine is a little different on the switches with the meter on the on/off and a momentary to actually zap but essentially it's the same.

John, yes he's got a good eye for style as well as function and his kits (and ARTF spin-offs) have certainly stood the test of time.  Moving on from the Middle Phase but wanting to remain with balsa rather than fibreglass technology, I thought about the Phase 5 or Phase 6, but in the end bought a Quark 2m short-kit from Ireland.  Although it might be a while before I have the time to actually build this!

Someone might come along who can express this more properly but as I understand it gliding is about the rhythm of gaining and expending potential energy (height, speed), whereas the power stuff is largely about the throttle... until the energy (amps or liquid fuel) runs out.

Yesterday I was trying to do a bit of knife-edge with the MP in the awesome lift from the bowl, but didn't manage longer than a fraction of a second each time as there's very little side-area to the model.  But, as my mate also pointed out, I didn't have the benefit of any thrust either!  ;D

Like everywhere, the good weather comes and goes.  

 Yep seems to have gone here too.

Still - it's cold, it's cloudy, it's drizzling but there's only a light, if a little turbulent wind so I thought I would check out some basic settings on a new to me Blaster 3. I wanted to check the basics like elevator position on the AMT before I add extra flight modes etc. It saves having to reset the tail in each one if I've got it wrong

I'm very impressed with the model, even with no additional flap settings programmed in yet, it would launch to a good enough height to check stuff out. It's a bit 'old school' compared to the latest ultra slippery DLG's but it suits me and my preference for a more floaty flying experience. The weather is better tomorrow so I may take it out again now the flight modes are set up.

 I have 4 flight modes which function properly but I'm struggling to get more than one control movement onto an additional momentary switch for rotate....any Multiplex Royal Pro experts out there ?

Whilst doing other various repairs on my models this weekend I pulled my Guillows Skyraider off the shelf and commenced repairing the effects of winding without a blast tube.  BTW, on its last flight (at WESTFAC VI in 2017) it made a 44-second flight in the condition shown with the bottom right longeron severed in two places!

I made a crutch to replace the damaged lower longerons and while I was in there I moved the peg forward to center the motor on the cg.  And yes, with the peg moved forward I can get a blast tube in there for future flights...

Workmanlike repair on your Skyraider Mike. It's good to see you working again P40 - when did you stop?
Very nice Aeromasters - true classics!

Thanks John.  Covered and doped the Skyraider repair yesterday, shot it with paint today.  Am I a hoarder if I covered and painted it with the same stock used when I built the model in 1995?  While in repair mode I patched some dings and tried to resolve a warped stab on the Navion, built replacement struts for the Zippy Sport, made a new noseblock for the Skyshark and mended a broken-off wing on the Guillows Typhoon.

Cheers,

Mike

Today, the Free Flight Gods smiled, or maybe just smirked a little. Anyway, I actually made it out to the field and actually FLEW A Model!!

As some of you know I've been building, but getting the finished model out to the field has usually run afoul of life issues or weather. Mostly weather.

But today  as I packed up a few of my offerings to the FF Gods the wind was a barely felt 2-3 mph.  But as with my luck by the time I drove the 2 miles to the field it was in the 4-5 mph range.
I was not to be denied. First up was the B-70. Put in about 50-60 winds, and as expected it flew just like a lawn dart!! Way too nose heavy. Back to the shop to take some weight out.
Next up was the Chipmunk, my very first build last August. Again about 40-50 winds and a gentle push into the breeze.  OOPS!! It was so tail heavy it performed about 90% of n 8' loop then settled into the grass. Okay, back to the shop for that one to ADD weight to the nose.

So then it was time to try the Bostonian Porter. Put in 50 or so winds. By this time the breeze was likely in the 5-7 mph range, but what the heck. I released it at eye level with a gentle push and OH MY GOSH, My very first successful flight of a rubber powered model since getting back into it last year!!

Okay, it was a single 50' diameter circle to the left, climbing to about 20' before gently settling down. But It was stable, no stalling or twitchyness. And I was able to repeat it 3 times!!  For me it was a very successful outing! After the third flight the breeze was still building and downwind was a somewhat busy road so I decided to pack it in.

Pic #1 The three I attempted to fly today.
Pic#2 And away it goes!!
Pic #3 Okay, I screwed up the release but it recovered and flew well after that.

Well done Dan!

There's no such thing as the wrong weather, only the wrong models!

Me, my mate Mike who kindly dragged me away from work again yesterday, and a paraglider who I've met before up the hill - who scratched away for a good half-hour before landing out.  (Paraglider's best flight from the hill last summer was 4hrs, ten thermals, 6,000ft max, and landed at Popham some 40miles away.)

Like Lot's Wife and Daughters, I couldn't resist turning around for one last look... but at least I didn't turn as salty-white as the hill!  ;D

I finished a Jimmy Allen Fokker Triplane peanut - 12" W/S. Struts are split and sanded bamboo. all surfaces are covered on a single side with pre-stretched/shrunk tissue except for the fuselage. Finished weight including carved prop and an 8" loop of 1/8" rubber is 10.15 grams. So far, only a couple of test glides and a powered ground takeoff roll. All balsa was stained with a red Sharpie before covering. The cockpit combing is black tissue paper rolled up into a tube, glue soaked and formed on a template. Wheels are cross-laminated 1/32" balsa bushed with paper tubing formed on a wire.

You don't do things by halves do you old chap?  Condolences.  What have the bods from the AAIB had to say?  Pilot error, loss of structural integrity in flight, or loss of power at an inopportune moment?

Oh dear Jon - that is a shame. 

I recall that the Wot4 was quite forgiving up to a point but push it just that little bit too much and it would self destruct.

Gosh all that seems a long time ago!  Here I am now with 20p worth of tissue and balsa sticks and happy as Larry (whoever he may be!).  But you know the odd thing is that when I came back a few years ago I bought myself an ARTF - can't remember what - and did bend it but was not too distressed because I can remember thinking - so what I can always buy another one. But bending a little FF model and i feel "Oh dear what a shame - all that work......!"  Must be an age thing.

I hope none of the gear was damaged unduly.

What have the bods from the AAIB had to say?  Pilot error, loss of structural integrity in flight, or loss of power at an inopportune moment?


Good questions Major!

Essentially there was a system failure in the aircraft, but the pilot remains culpable - as will become apparent as you read on.

The model was intentionally put into a throttle-off stall at good height and well out over safe ground, with left rudder and some left aileron to instigate a left-rotation spin, the normal procedure being to centralise controls on the transmitter after three turns at which point the model would normally immediately resume normal flight.  What happened however is that none of the surfaces centralised after three turns and with no control possible the model spun hard into the ground (it was recovered in several parts but with all servos and surfaces in the position they'd been put into to to first instigate and then hold the spin).  This points to a possible connection failure within the model.  The battery still had plenty of juice (was found to have about 45% capacity which is fine for a LiPo, but was badly bent and has since been discharged completely and drowned in a bucket of water for safety).  There's the possibility of a less than perfect solder joint in the primary connection (Deans plug) between the battery and the ESC, or the possibility of a duff ESC or receiver (both very hard to test), or the possibility of a less than robust connection somewhere else in the system - which is normally fine but fails at extreme- or negative-G?

The last item above is a strong possibility as previously in the same flight I'd been doing a large loop and the model failed to respond at the top of the loop to a reduction in the throttle stick from full to zero - it carried on at full pelt - but did kill when I hit the separate throttle kill-switch which over-rides the throttle stick.  This might seem to point to a problem with the transmitter, but I think its just a coincidence for the following reasons:  (1) I repeated the same full-throttle loop and had the same problem and resorted again to the kill-switch which seemed to do the trick, but when I tried a loop on lower power (about 70% throttle) it responded normally at the top to just pulling down the throttle stick to idle; I think it is co-incidental (and therefore a false lead) on the basis that the kill-switch was used at roughly the same time on both full-throttle occasions as extreme- or negative-G happened to cease of its own accord as the model came round into the vertical dive part of the loop. (2) I've tested the transmitter throttle-stick on my other models (power off and on the ground) and it is working normally, and the monitor on the transmitter screen confirms this.  (3)  The budget servos I'd fitted on this model (foolishly as I'm not normally one to skimp on these things) had seemed particularly slow (I was indeed having a lot of trouble settling the model's rates and expo to give a smooth response), and so either they were part of the problem in themselves (drawing way too much power) or they were the canary in the coal-mine for a problem further upstream?

These are the theoretical possibilities.  Tomorrow I'm going to set up the whole caboodle on the bench - servos, RX, ESC, motor bolted to a block of wood and minus prop - with a watt-meter connected inline and test each component... assuming they all work after the hefty impact!

If you've followed all of this, then you'll have spotted the element of pilot error:  after the loss of throttle-response during the first earlier loop, I should have landed the model immediately and kept it grounded until the problem was fully solved and corrected.  I didn't do this and have paid the price.  If there is any mitigation for my less than cautious attitude, it is that the two further loops at full throttle again and then two-thirds throttle were revealing (the latter didn't result in any response failure), as of course was the complete loss of response during the final, fatal spin.  Going over all of this therefore helps point to the strong possibility of a 'labile' connection at extreme-G... which might never have been apparent during static investigations!

Post by: Jack Plane on January 26, 2019, 05:52:33 PM
By the way, whatever the outcome of my investigations tomorrow nothing will be completely certain, so I've already condemned everything and ordered a new airframe and complete new set of higher-grade components (ESC, motor, and servos) plus a new receiver.

In consequence of which I'll be eating a lot more tins of budget baked beans for the foreseeable future...  ;D

Post by: OZPAF on January 27, 2019, 06:34:34 AM
Good luck with your trouble shooting Jack. It would seem like a receiver problem to me. Either the voltage regulation from the ESC dropped below the threshold or it lost the signal also possible on a low rcvr input voltage.
The worst part is  - it will probably be impossible to find out.
I had a model do a perfect slow roll into the ground on a bypass without responding to any control input and was never able to pin the problem down.
I would be checking the ESC regulation with say the elevator servo loaded(weight perhaps?) and the other servos moving and the motor on full power.
Good luck with the next one.

I reckon you're pretty close to right.  I'm about to lay out the waifs and strays and wire them all up (just popped into the house to make a pot of tea) so might find out shortly...?

In the meantime, kicking myself for having gone down the double-expense of the electric route when I've got a perfectly-functioning Acrowot with its reliable, well-mannered and more-than-powerful ASP 70 four-stroke, I took it out earlier into the garden with the cowling off, pegged it down and gave it a bloody marvellous run!  Fantastic 22 minutes on a full tank at half to full throttle!  ;D

I'm sure the replacement electric Wotty will be fine, but he thing to remember is that I bought it (plus a set of expensive 4s 4,250mAh LiPos plus an expensive quod charger so I don't have to wait four hours to charge before popping up the patch) to do a job:  to get out flying every lunch-hour the weather permits to practicing every B-Test manoeuvre and eventually the whole sequence in all conditions of wind until it becomes second-nature.

But the thing I'm really looking forward to making (after a new Peanut rubber job in time for the April Indoor Nats) is a laser-cut kit of a Mick Reeves Gangster 63 Lite - dead retro! - for which I've got a very sexy-looking OS 35AX two-stroke waiting new in its box.   8)

Well Jack - that seems a very healthy pick up from the minor setback. I always liked the look of the Gangsters and have also been impressed by a friend who has a Bridi Dirty Birdy retro pattern model and is now more than halfway through a UFO - a later Bridi design. They make really good sports models.

Ah variety! It can't be beat.

Jon, I do not know if there is any connection as not au fait with radio to any great extent but a chum of mine who flys in Hampshire which is not that far as the crow flys from I presume Oxfordshire (well the drive isn’t) had a similar problem as did others in the club - for no reason models went in!  They were all electric powered by the way.  Pilot error was the first choice but that meant suddenly capable people has lost their touch.  Then interference was considered and a number of reasons emerged indicating that interference on 24 was a likely candidate.  I understand the matter was referred to the BMFA and after quite a bit of discussion etc. they favoured a duff ESC or battery but some I think felt this was questionable because it meant a few models had the same problem.  The BMFA News had some articles I think earlier in 2018.  I gather that the final recommendation was that a separate battery was installed to power the RX direct frather than via the ESC.  Since then I have lost touch but could I think easily get myself updated if you would like.

If there are any power lines in the area a bad transformer is a possibility. My R/C club had a number of ships go in because of that a few years ago.


Title: Re: What Did You Do Airplane Wise Today?
Post by: Jack Plane on January 30, 2019, 05:40:02 AM
Thanks folks.

After exhaustive forensic analysis and testing of recovered components from the wreckage of the 1st Mrs Wot4 (the logical steps of which I won't repeat here), I finally eliminated everything from the equation... except the fact that the RX was not very cleverly positioned in a tight space below the servos in such a way that a fair amount of wiring surrounding it could have compromised signal getting to it during the fast spin?

But, having absorbed a whole new level of understanding of electrics and electronics, I'm moving on:  the 2nd Mrs Wot4 has now arrived.  For extra safety I'm using a completely different power-train (slightly less power, a bit more duration?), a new Spektrum AR610 receiver (the one with no external antennae) with a separate NiMh battery to power it.  I'm also fitting exactly the same Futaba standard servos as I have on the Acrowot.

Onwards, upwards and... err.. downwards only under normal power, signal and control!  ;D

Post by: SP250 on January 30, 2019, 12:16:18 PM
Jon

I've lost two Wot 4's in a similar fashion.
The result of subsequent investigation was that the ESC's supplied with the kit were going "brown out" and stopped supplying the RX with power.
I put a temperature sensor on one and it was within 10*C of its limit (100*C I think) on the first flight.
Half an hour later on the second flight it started at about 30*C and went over the 100* and stopped working (which shut down the motor).
I put a decent Hacker or Jeti ESC in there and opened up the air flow - no issues since.
Needless to say I was using a separate RX power battery for the tests and took out the pos feed wire from the ESC to the RX.

Hope that helps

Cheers for that info John.

George at 4-Max has supplied the new motor and ESC with the new Wot4.  He specifies the ESC on the basis that it must be rated at least 25% higher (at standard not peak) than the max amps the motor would pull with any given prop.  His ESCs aren't cheap, but well worth the investment... as a written-off model isn't 'cheap' either!

I must say I really like the Wot4, and looking forward to getting the replacement ARTF put together and airborne.   ;D

Today I made and flew this 1/36 scale (≈ 259mm,  10.1 " span) Su-7 chuck glider. I like the Su-7 and it's a candidate if I ever try EDF. I had a feeling it might be the kind of model that was happier flying uspside-down than right side up, but not a bit of it. It seems extremely stable in roll and yaw, on a windy day, but establishing the best CG might take a while. There's no washout and no dihedral, and it flew fine before I fitted the wing fences - I'm not sure what difference they make yet. The lead weight taped down at the CG is to mimick motor weight. A possible show-stopper for lectric flight might be the small intake area, and perhaps a round fuselage as opposed to the flat-sheet profiles might make it unstable.

It was good to have a model - any model - to muck around with.

  Hi Stephen,  The SU 7 is a favourite of mine as well, I built one for an indoor event for "prop driven" jets about 20 years ago. It flew so well I drew up the plan and had it printed in our local Free Flight newsletter, a couple were built and they also flew well. It was 11,5" span.  I've thought several times it would make a good EDF project so I will watch your progress with interest  ;D

It may be a long wait!

I cut a catapult notch in the chuck glider and have been launching it with a 1/8" rubber loop. I've increased the lead weights on the nose and amidships to simulate a coreless DC motor+fan and a supercap, a la Sonex413 Youtube video, https://www.youtube.com/watch?v=vF1mOyZc1lk. I get the feeling from the stretch of the rubber that it might need a good bit of power to keep it in level flight and I rather doubt that one o' those motors spinning a ducted fan could do it. I've read "40g thrust" quoted in specs and on RTF drone websites, with respect to the 8.5x20mm motor, but I suspect that'll be  static thrust with the ideal two-blade propeller.

It is fun John, but it's distracting me from things I should be finishing in anticipation of some Spring grass to fly over! I must get that Leopard Moth off the shelf!

 Printed it,  pieced it together, studied it.
Referenced it against 3 views and 3 other plans.
Then threw it into the waste paper basket  ... grrr.
 Surprises me that some go to the trouble of printing / dispersing plans so full of gross outline errors.
For NO apparent reason beyond sloth in prior research. 
Now proceeding by working from 3 views... which also vary,  but at least manageably so.

I started looking for my next build!!

After encouraging test glides of the Hemiptere I can't do any thing flightwise outdoors, (or indoors either) for the next several days due to either wind, rain, or both, so might as well start building something!

What am I looking for?
1. Something unusual, or at least something that hasn't already been modeled a gazillion times.
2. Something scale.
3. Something with one wing. ( Not ready for the intricacies of 2 or more wings. (The Hemiptere doesn't count because the wings were joined/mounted with struts! )  :D :D
4. Wingspan somewhere between 18-30"

Spent a few hours the last couple of days wandering through our plan gallery, Outerzone, and Areofred but so far nothing has jumped out and yelled "Pick Me!, Pick Me!"

Will just have to keep looking.

Airspeed Tern?  It has been modelled, but it's not all that common.  If you can find a plan for one at the upper end of your wingspan requirement then I should think it'd make a good bungee launch subject.  If you do find a plan for one with a span of around about 30"-35" I'd also be interested.

At the 5th Jan meeting at Bushfield Peterborough, the peanut sized Pietenpol was looking a bit battered.
I managed to get it back together for today's meeting at Bushfield.
I managed to get it flying better than previously, but I do think that it's carrying a little too much weight with the CO2 version.
I did have to add tail weight so a bit of re-organisation might help. Nice to see it in the air again though (knocking on 14 years old).

Russ,
        Good to see you are getting sorted as it looked promising on the 5 Jan. Just a thought could you move the tank a little forward to give a slight movement forward of the CG and when full it would move forward even more to control any nose up at the power burst.

This past Summer there was discussion regarding expanding the Sundog P-30 design into a series to include other WWII fighters that participated in that momentous campaign. I got interested myself, and expressed some mild interest in figuring out whether I had the commitment to take on such a project.

But Ma Nature intervened.

My Wife of 48 years endured a fall in a scorching hot parking lot in Phoenix AZ on a 114 degree day and suffered serious burns from the hot asphalt, going an extended time when she was neither able to rise, nor able to get help, resulting in second degree burns that required five skin grafts. Seven months and about $100,000+ worth of excellent care later, she is fully recovered.

For my own part, four EMT visits for oxygen and two hospitalizations for CHF, COPD, and Bronchial Spasms due to extended inhalation of sub-freezing air derailed any thoughts of embarking on the above project until last week; when I simply said, "enough, I need to get on with my life again".

Meanwhile, the Veterans' Administration is working me into a sequence of evaluations, rehabs, and potential long-term therapies to remedy my extraordinary events.

Following the subject discussion in the interim, I took note that some interest exists to move the rear motor peg forward by one bay, to improve balance. It works, but seems a compromise to me. I would rather move the wing aft by about 1/2 bay, and retain the original motor peg position. I think it would better help with motor duration.

Some wing structure revision has also been experimented, and looks great. I want to take it one/some (or so) further, by redrawing the wing to incorporate a shallow undercamber in the aft half of the airfoil, and restructuring the wing construction to make the stressing more geodesic.

If this all works, the same basic design features will be incorporated in additional WWII European Theater aircraft models of a similar P-30 eligible semi-scale nature, and hopefully posted here in the design gallery. Since the BoB commemoration is past, it will no longer limit design choices. Designs should be limited to single engine fighter interceptor, ground attack, and conventional single pilot combat aircraft, which saw combat, and were fielded by the Allied and Axis Powers in Europe.

Suggestions for appropriate aircraft designs are hereby solicited.

Work will begin with building a Sundog P-30 exactly as drawn in the Gallery, to get the whole original concept under my belt, and well understood from a for-real standpoint. Modifications will then be constructed and tested using an 18" (60% span size) WS format. Considerable liberties will probably be tried to reduce weight, better control balance, and perhaps enhance aerodynamic performance. Laminated outlines incorporating cracked rib and turbulator spars will likely accompany the modifications.

Being of moderately sound mind and body, and the river don't rise, I'm hoping I can get this off the ground and into reality.

Greg

Further progress of the model depicted in 1271 above.

As no one knew what it was  I will tell you.  It is a half size version the "Hercules Airliner" - "airliner" being a gross misdescription. I think you will agree it is very Bowdenesque which really is the charm of the thing.  It was designed and kitted in 1934 by the Model Shop Newcastle (NE England and Geordie Country).

It came to my notice from a chum who has built a full size version- 48" span!  Apparently it flew more or less straight off the board.  And has not required any trimming to speak of.  I share the view it was probably ahead of it's time. I believe no plan could be found but a model built pre war came to light and the current plan drawn up from that.  It was all in Aeromodeller by Alex Imrie.  October 1995.

It works with the rear peg almost in the original position - just an inch or so forward bucking the current tend.  Originally the "peg" was a hook attached to the stern post!! Using the full length of the fuselage.

Thank you Ricky. Yes - perhaps Pinocchio would have been a better name?  Or Nosey? :). Presently it is nose heavy but predictable perhaps.  I think it will even out a bit when covered and motored.  We shall see but one other builder said his (F/S) version was a little nose heavy. My other chum who is pretty good said his was on the button.  I am hoping Bushfield might work as well.  But locally - a few minutes walk from the house is quite practical too.  Might mean moving a few cows though.

I could seriously consider sending a snatch team to capture Mr Kelly and "persuade" him to divulge his secret ability to cover and finish models to such a high standard to us lesser mortals.

Thanks for all the compliments on the Wicko, but you're being much too kind.  The front end came out pretty clean, but there are wrinkles on the stab, marks on the LE from teasing out wrinkles there, and the tops of the wheel pants show some incipient varicose veins where I tried to stretch the tissue too far.  The sharp edges and graphics of the printed tissue draw your eyes away from the flaws...

John, the side windows were done by tacking a single piece of clear giftwrap across both windows on each side of the fuselage before covering.  I printed the tissue for the fuselage sides, cut out the window openings, then applied the tissue over the glazing and sealed the edges down with thinned canopy glue.  The side tissue is a single piece from the aft end of the cowl to the back - easy because the sides are flat.  There were a few wrinkles on the diagonal at the bottom of the rear windows, but between a water/alcohol mist and some nitrate they're just about gone.

Spectacular photo Derek - quite remarkable.

I'm rushing up a model to test my new 0820 coreless electric motors that arrived from China yesterday. My interest is in using these little motors for ducted fans but I think I'd better take some baby steps first. The supplied props are much better than I'd expected - and much bigger. Specs on various websites state "max prop size 65mm" for the 0820 motor. It turns out that they're referring to radius. These motors came with > 65mm radius props. . .5 1/2" diameter in fact. The vendor also bundled in a neat gearing system, about 5 to 1 reduction. It looks to me as if the energy lost in the gears might well be in the same order as the efficiency gain of a bigger slower prop. Lots of playing round to be done. I'm lucky in possessing a laser rpm meter so I shall be making lots of measurements. I jammed a motor into one end of a plank of balsa and ran the  motor on 1 1/2 volts. Finding the point along the plank where the motor could hover gave me a very crude idea of static thrust. It seemed to be about 6 grams. I think it should fly the 16" span model I'm nailing together, given that the capacitor will deliver 2.7 volts initially. Holding the plank as it 'hovered' also alerted me to what seems like very high torque, and fierce (relatively speaking) gyroscopic forces from attitude changes. I hope this won't be problematic.

The pic shows a motor with prop and a 10 Farad capacitor with the plastic sheathing stripped off to save ≈ 0.1g weight. BTW the seller on Amazon wasn't lying about the weight of these motors: 4.9g each including wires. The 'supercap' weighs 3g in the nude with its wires clipped short.

Stephen.


Title: Re: What Did You Do Airplane Wise Today?
Post by: OZPAF on February 20, 2019, 11:52:47 PM
Thanks for that Mike. Using such thin plastic would be a large part of the neat appearance - no lumps.

Stephen - I think from what I have seen that you could expect a lot more than 6gms thrust with that motor/capacitor/prop combination.

My friend's effort in India indicates an initial thrust of around 16 gms on a 10F suopercap with a 65mm dia(not radius) prop. This quickly drops though but from analysing the flight video I would estimate that it ran at around 10g for another 10 secs or so.

Interesting idea as they are very high reving - you would have a good chance of making an edf work.

John


Title: Re: What Did You Do Airplane Wise Today?
Post by: Prosper on February 21, 2019, 02:50:35 AM
Aha, thanks for the info John. The ≈ 6g thrust was on 1.5 volts only. I have no idea about electronics so I don't know how linear the curve of volts against revs would be. The high revving is indeed why I thought of EDF suitability, but as yet the whole area is a mystery to me - quoted unloaded  rpms are 40,000 or more for this motor, and yet it happily spins a 140mm prop at 'real world' rates. I believe (perhaps wrongly) that obtaining best efficiency from electric motors is a matter of not overloading them, i.e. having them spin fast, but I don't even want a caged fan spinning at 30,000 rpm :o. Anyway I have a battery for my rpm meter arriving today along with batteries to charge the capacitor so I should start finding things out soon.

Stephen.

Hi Stephen, are you using the gearbox? If not that's an enormous prop for direct drive  :o

The 8.5mm coreless motors (depending on quality) will give you 35-42g of thrust on a 65mm King Kong direct drive prop revving at something like 25,000-32,000 rpm on 1 cell ie about 4 volts. This sounds fast but is perfectly normal for electric and exactly where they are most efficient at approx 75% of the no load speed.

Would you be able to share your motor source? I've tried the Banggood geared ones similar to the Voodoo style but they aren't great on thrust (the prop is rubbish.) Fine for a fun model though.

6 grams of thrust really does sound low for an 8.5mm even at 1.5V  :-\ a 6mm motor should easily do 10-12g on 1S these days. This would be with a 32mm prop so could be used in a ducted set up.

Hullo Jon, I looked on Amazon and can't re-find the exact line I ordered - that's the problem with generic stuff from China. I can tell you that the vendor was/is called Ascot City and the name 'Sourcingmap' came into it. The offer was 2x CCW 0820 motors with the extras mentioned above. Less than a fiver each inc delivery IIRC. I bought two pairs, knowing that it was a bit of a punt. The supplied props are handed to spin directly - gearing them would have them spinning backwards. This added to my confusion as to what I was dealing with - I was expecting tiny propellers and to chuck 'em straight in the bin. I couldn't really believe that even tiny props could spin at 10s of thousands rpm. Perhaps the motor simply can't perform with such big props. I just tested the static rpm: 6,500. I may cut down one of these props but it seems a shame since they're actually quite nice and might be useful some day somewhere.

0820 motors with the extras mentioned above. Less than a fiver each inc delivery IIRC.

I bought 5 of these with gearbox and the same size prop.  Using the gearbox the 5.25" prop just did not work with a 1S lipo (nom 3.8v).
The models weighing between 20 - 30g would just about maintain height from a hand launch.  I cut the props down to 4" and 4.25" dia and they climbed well and would maintain height on half throttle (radio controlled of course).  I have made a FF model with same motor and battery but haven't wrung it out yet.  Don't forget to oil the bearings on the gearbox.  Be careful when assembling the bits and pieces - it is easy to push the shaft through the rear plastic cover.  Support the wires with UHU Por or similar - the wires can fall off very easily.  Other than that they work well.  I understand from a clubmate that for direct drive there are small drone motors that can be used in this way.  Regarding ducted fans - there is a keen group flying these (radio controlled) in the St.Helens area.  The prime mover makes and sells very light 3D printed duct/motor mounts complete with motors and small commercial 3 blade props.

"She flies, Orv!"

"I told ya she would, Wilb."

Well, after a fashion anyway. This is with the plastic prop driven directly. It's windy today but too lovely and Spring-like a day to waste so I had to give the model a chuck even tho' it's not finished. With a couple of AA batteries in a pocket and the charging lead sticking out, fuelling up these things is a doddle. I was charging for 6, then 10 seconds per launch. The wind made trimming decisions difficult. After a few flights it decided to do the right thing and fly into a tree after about fourteen seconds of circling. Getting it down was a pain, involving a stepladder and loppers. I made the model strong though, to imitate the weight of scale models. I look forward to experimenting with different props - maybe the key to this business. I guess the question is what's the duration going to be like?

Pictures, 1) checking the no-load rpm. The motor runs a long time under no load, this is well through the run but even at the start I think it was reading less than 30,000. The motor is rated for 3.7v so 2.7 is tame, but perhaps lets the motor last longer. The battery box is visible behind the stbd wing and the end of the improvised charging lead pokes into the picture centre-left.

3) and 4) The model is nose-heavy so I fixed the capacitor against a cabin bulkhead. There is a slot below the pins through which to insert the charging lead. The improvised circuit breaker is probably mis-named: the balsa case indicated contains two brass strips sprung against each other - pushing a strip of thin plastic into the slot (right-hand pic 4) separates the brass and breaks the circuit. Probably the plastic strip is the circuit-breaker. The tangle of wires can be tamed when I have a clue what the best final arrangement might be.

The model needs a windscreen and chin cowling and landing gear to finish, but adding up the various sessions I reckon it took less than two days to get to this stage. Weight as seen 20.2g; wingloading 0.084g/cm2 [0.54g/sq in]. A 30 second charge gives a static run over a minute with the prop fitted but I would guess only 40sec of this - perhaps less - is powerful enough to keep the model aloft.

Thanks for the info Ralph. I was confused but I'm even confuseder now. The motor leads on these motors look secure - they're supported by a plastic plug and I gave them a waggle on first inspection. These are drone motors, according to the comments on Amazon.

Stephen.

You are on the way Stephen!. Wilbur is right :)
Check out Utube site sonex413 if you haven't already - a mine of information there.
As a comparison my friend in India is flying a 20g model on a 720(7dia) motor on a 10F capacitor with a direct drive 65dia prop. He has only charged it to around 3.0v.
Not sure of it's thrust output but by rough estimates from the climb angle on the video it is close to 16g at launch dropping quickly to stabilise near 10g for around another 15 - 20secs? Average flight times are 30-40 secs with a longest flight of 1minute(no doubt with a bit of thermal; assistance).

Location is a little different to yours Stephen :)

That does look very much like the banggood one: https://m.banggood.com/Coreless-Reducer-CW-Motor-Propeller-Combo-Set-For-RC-Models-DIY-p-998786.html

I bought it to use the gearbox as a motor mount but did a quick thrust test. I got around 15g on one cell - not great at all. The motor wires were the same, I needed to swap positive and negative to get the correct rotation.  I will test the BG motor on DD too at some point.

Without the gear box it will be massively overpropped and to be honest I'm surprised you're getting any thrust at all  :D if you PM me your address Stephen, I will pop a couple of 65mm props in the post to you (I have loads spare for E20) you should get a lot more thrust with them.

As John suggests by getting the efficiency right a much lighter set up is possible with a 6 or 7mm motor.

Post by: Prosper on February 22, 2019, 01:27:37 PM
Jon, that's a very kind offer, and I might take you up on it down the line - but for now I'm keen to see what can be done with balsa props (see below). Yes, the motor you link to could be the identical item - that's why I call 'em 'generic' - but it looks as if the wires may enter at a different spacing on the backplate. I bet there are whole factories in China churning out these babies. When looking into these motors I read the drone enthusiasts writing that if you run them backwards they don't last long - I'd have thought they'd be entirely symmetrical and would run as well one way as t'other. The 'droners' also say they should be run-in by running at 1.5v only for some initial period. When one breaks I look forward to breaking into it to see what's what.  Do you think a 6 or 7mm motor could fly a chubby model like this with 0.56g/sq in wingloading? I think I may have underestimated the potential of these little things.

John, thanks for the link. I seem to recall from a different thread that you're the instigator or designer of the model in the video. It's a charmer.

Thismorning I made a card windscreen and a balsa lower cowling and reworked a couple of 'pre-owned' prop blades and an old hub into a prop, all for my supercap test model. I haven't measured the prop pitch but it's not quite as fine as the black plastic prop that came with the motor. I guess the area is about the same but the diameter's less: an arbitrary 116mm (just over 4 1/2"). The prop weighs 0.6g against 1.1g for the plastic. Model weight up to 21 grams, 0.088g/cm2 [0.56g/sq in].

After the fog lifted I managed to fly the model into several trees at lunchtime and was getting tetchy, but the wind died later and I got some better flights. This flight (https://youtu.be/D9XorStMx-s) has 15 seconds of charge (sonex413 says 30 sec = a full charge and he's got the necessary meters to measure it so that's good by me). It's a bit stally because I'd moved the port aileron down a touch to open up the turn. If there's a flat calm I might try a full charge but I'm tired of it hitting trees. . .yesterday stepladder and loppers; today ladder, bowsaw, loppers and hook. I notice the battery voltage of the two AAs I'm using for charging is down to 2.8v so they're holding out well given the number of charges they've already provided.

Stephen.

Stephen, The brushes in these motors are very fine wires, to reduce friction and they are arranged to be "trailing". If they are run the wrong way then the free end of the wire can easily catch and that is the end!!!

Using the brushed motors as we modellers do, with higher currents than what the motors are designed for, the contact area between brush and collector has to be as big as possible to transmit the current without generating to much heat. The run-in is done leaving the motor running for some time without load and at lower tension than the designed one. You could use one (1) NiMh cell for the run-in.

Thanks Urs - I'll do that with new motors in future.

Today I sneaked out onto a corner of my neighbour's field in the fog - I shouldn't be walking on it probably, with the grass still on the frail side, but I couldn't resist trying my new supercap test model with a full tank and throttle wide open! I used a new pair of batteries - the first set is down by nearly half a volt. If I continue this game I think I'll use the full-power phase of the batteries for flying, then put them to domestic use - electric clocks and suchlike.

Anyway I got this video (https://youtu.be/lpgHE-wQIzI). I think in warm dry air and with a more open turn radius more can be expected - and I've no idea whether I'm near the optimum regarding the prop/motor combo. I'm pleased (and surprised), because this model is no lightweight; the wingloading is right in the same neck of the woods as all-sheet WWII monoplanes I've made in the past. The weight and loading is the same as in reply#1321 above, but I cut down the prop slightly to 110mm (4 1/4-ish inches) and increased pitch slightly. I noticed in short flights yesterday that what should be a pretty stable model was showing odd misbehaviour, and this reminded me of the behaviour evinced by rubber scale models I've flown with too-fine prop pitches. The current pitch is 17deg at 75% radius which I think is a PD just over 0.7.

Apart from tinkering with this model, I think it's time to consider ducted fans. As I drowsed waking up today I also thought of the scale subjects I've rejected as rubber models because (mainly) of tragically short noses, and ones I've made that wouldn't fly. I made a Supermarine Spiteful that was a complete failure due to the required noseweight. I wish I'd kept the carcass, to try it with a supercap setup. . .

Stephen.
P.S. the noise these things make is annoying but it's not nearly so irritating in reality as on the vid. The camera mic really exaggerates the noise level.

You're on the gallop today Jim :). Look forward to the pics.

Here's another supercap flight (https://youtu.be/-vuPRpaJYZ0) on my own patch - warmer dryer air maybe but I didn't dare trim a wider turn - just as well as it would have hit something. It landed before the capacitor was completely discharged and this time had 18.5° blade pitch as best I could measure. I probably need to go finer again. I may try reducing the blade size also, but it seems to me that against motor efficiency must be set propeller efficiency - it seems to me there's no good in having a motor working at its best if to do so means it has to drive an inefficient prop. Another thing I did today was to make an annular shroud or duct for a test fan, 35mm dia. Haven't made the fan yet.

Post by: OZPAF on February 24, 2019, 07:51:55 PM
That was a nice flight Stephen. I think the motor seems to be working better with the lower pitch. The model still has ample flying speed and the glide indicates that the pitch is not too low as well as the glide angle is quite good. Not a bad motor run time either.

Post by: Prosper on February 25, 2019, 03:12:40 AM
Hi Don - it was unclear to me too, looking through the tiny camera viewfinder :). I can't wait for the grass to grow a bit on the bigger field so I can use that.

John, those are interesting points. The motor has sounded a lot more buzzy and harsh in the last few flights - it might be simply damage from the number of times the model has smacked into tree branches etc. at full tilt, or perhaps it's the prop resonating or somesuch. I know that when I tried a steeper blade angle (20°) it ran much more quietly (but the model flopped around and found it hard to keep airborne for long). Yes, I think perhaps I was in the right area with 17° but must explore the finer side too, and will watch how that affects powered-glide angle near the end of the flight. It's so hard to make assessments outdoors because of changing weather. The powered glide phase is interesting because when I pick up the model and see how feebly the prop is turning I realise that it can sustain the glide much further through the capacitor voltage than I thought possible. I really think that if I can open up the turn from that steeply-banked pattern it will make a big difference, and although I only built this thing to get a feel for this supercap malarkey before delving into ducted fans, I'm now thinking there may be a niche for propeller-driven scale model subjects unsuited to rubber by their layout. I know that electric flyers will say "duuh, you just realized that?" but I'm really referring to capacitor power as that stuff with zombies and voodoos still doesn't grab me.

If the prop is bought to a sudden halt from a crash, esp. when there's still a lot of charge in the cap, does that damage the motor?

Stephen.

It is possible that there the high current of a stalled motor  in those circumstances could burn the brushes/pit them. This would cause the brushes to arc more and that would make more noise.
It's also possible that the motor may still be over propped. However it is still doing enough revs to fly the model well on the low pitch setting.
I don't think I would go to a higher pitch from this point - in fact, I would consider slightly lower to see if it enabled the motor to rev a bit harder which would reduce both your current consumption and the torque - thus reducing the angle of the bank on the left turns.
A check of the current consumption with the prop would provide a better guide to how hard the motor is working.

[quoteI realise that it can sustain the glide much further through the capacitor voltage than I thought possible][/quote]

This and the soft power run down are attractions of capacitor power. It appears to make the model much easier to trim. They have a similar power run down profile to rubber, but at much lower torque and thus higher revs with consequent smaller props.

Was up at cock-crow to complete the installation of a new G-43BB in my Peanut Bristol Scout (test flights at Nijmegen last Nov proved it was underpowered with the G-28), with the intention of first outdoor trimming at the FF club field in today's fantastic weather.  It was running fine albeit with limited power on a gas charge, but unfortunately when I gave it a liquid charge something unpleasant must have happened (liquid entered the cylinder head?) as the engine now runs erratically with no real power at all!  :(

I'm almost at the point of ditching the whole CO2 thing for this model, intended for KS at the Nats in April, and converting it back to rubber (i.e. its original design)!  :-[

So, although model-less, I still decided to skive off work and went down to the field, chatted with the guys, and enjoyed watching Andy (abl of this parish) re-trimming his DPC Pfalz: https://photos.app.goo.gl/Q8wqwNV1ST5KtKxL7 (https://photos.app.goo.gl/Q8wqwNV1ST5KtKxL7)

A great afternoon's flying with some other OMFC members on the meadow

Jon,
      Do not give up on CO2. Liquid charges are a bit probmatic if you do not keep the tank below the motor when charging. I had this problem at the Nationals in August with the Comper until Andy Sephton pointed out the error of my ways. After that it was all go with 6 very consistent flights. Also be careful with O rings after CO2 ice has passed into the engine as it can nick the O ring. Also oil before a flying session helps. I tend to over oil as it ensures friction is minimised. The increasing of motor size is a good move as it is better to overpower and throttle down.
The flying site looked familiar but I cannot place it.

Love the Rapid Model Transport Device Chris!  What a great day for both aeromodelling and biking.

Thanks for the pep-talk Ricky.  I suspect that ice did damage the o-ring which I'll replace, but I also hope that the nylon seating itself hasn't been deformed.  The installation (of pipes, tank, motor-orientation) is almost identical to the G-63 in my Camel which is fine with a liquid charge, but maybe I need to re-think where the filler-valve emerges...?  Also, maybe I should only use sparklets rather than soda-stream.

The field is near Hungerford and is as perfect as it gets for both FF and RC.  Unfortunately the land has recently been sold and the new owners don't want the bother of a few quiet enthusiasts :'( so we're on the lookout for an alternative site.

Post by: DHnut on February 28, 2019, 04:23:15 AM
Jon,
       Good to hear you are going to purservere with the CO2. The Sodastream cylinder is safer as sparklet bulbs can have small flakes of iron oxide in them that do not do the motor any good at all. The Comper filler valve exits undeneath the fuselage so I have to hold the model nose up as the tank is inclined at 45 degrees and is behind the motor, if I were to do it again I would make it more upright.
I did recognise the field, as I was flying the Comper, Piper Cub (CO2) and a Magister there in May and August as I was staying at Kintbury at the time. Thanks to the Club for allowing this as a visitor. Sad that the new owners as not as accomodating as the previous one.

I used to put a magnet on the side of the sparklet bulb in an attempt to attract the little flakes to the side of the bulb.  It worked for me.  At the time someone said it cannot work but had to change his mind later.

Ricky

Hurrah!  This morning I managed to rescue the situation!   :D

Removed the entire cylinder and the piston to discover that there were nicks in both the piston-head and cylinder-head o-rings and also some aluminium debris around the top of the piston!  So cleaned everything and replaced both o-rings.  Also etched a mark at TDC on the flange behind the prop, so I'll always know to keep the prop-shaft away from this point when filling.

Not happy with the inadequate pressure of a gas charge (the G-43BB actually has a smaller tank than the G-28, although the benefit is that this can now usefully sit upright directly behind the firewall).  So taking care with the filling angle to ensure no liquid enters the cylinder, found that a 2-3 second liquid charge (up to 1.0g) now easily gives a minute's run at the desired throttle!  Very roughly the first 10 seconds is the burst (holding the model), the next 10 secs the take-off and climb, the middle 20 seconds  the cruise-phase, finally bleeding away into the decent and landing.

See last file in this album (the short, underpowered Nijmegen flight was with the smaller engine):  G-43BB static 70sec run (https://photos.app.goo.gl/LcaWJ8Na7A6Jf7xA7)

Achieved this with sparklets, as the charger is easier to handle than a mahoosive soda-stream with this Peanut model, and never had problems with using them previously with the Camel.

Today I made a couple of fans for ducted fan units. The first was a complete flop, five blades with shallow pitch and little twist, and so to try the other extreme I made the next one with very high pitch and lots of twist, but with three blades to save a bit of time. The hubs take 15 or 20 minutes to produce so a new hub can be made to suit each blade pitch and/or blade number. The blades, of which I made seven, are aluminium so can be broken out of a hub and be retwisted as desired and set in a new hub at any pitch.

Whereas the five-blader could only make a strip of tissue paper flap feebly, the three-blader blows bits of balsa and paper off the work table, so is going in the right direction, but what to try next I haven't decided. The shroud or duct should really have an aerofoil section lip to develop more low pressure at the front than the fan alone does, but I haven't thought of a light or simple way to make such a refinement. Static tests can be - or are - very misleading, so I think I'll turn out a really basic glider to act as an aerial testbed for various fans.

Stephen. P.S. this is a pusher arrangement - fan spins clockwise as looked at in pic

Took advantage of my clean work area to patch up and scan some early 1930s plans I purchased in a cigar box off ebay in January - assorted simple scale plans from Megow, GHQ, UMC, Aircraft Models Co of America.  Some of them were pretty ratty, with slices, tears, glue scars and remnants of prior construction adhered here and there, but several were plans I hadn't seen before and I think I've cleaned them up enough to be useable.  Thanks to Ratz they are available in the plan gallery.  I've got a few more to do but need to take a break...too much time in front of the computer.

 I'm  interested to watch your progress with your ducted fan units Stephen.  I was just searching in my shed for something and came across a fan unit that I made nearly 25 years ago, I sent to the U.S, for "kits" that were advertised in ,I think, Model Builder. They comprised an ST2 electric motor a foam cone for the rear and several pages of instructions. Basically they used a paper tube with laminated balsa rings for strength The fan blades were cut from a plastic container fixed to a balsa hub, they also had 4 curved flow straighteners.  I built 2 of these 2" diameter units and fitted them to a 30" A10. It struggled, the motors were supposed to use 3 Ni-Cads so I ended up with FIVE, then the blades shed themselves so I pinned them to the hub and managed to get a couple of flights of over about a minute. It was very marginal and needed ideal conditions and I eventually broke it.   Just though you might be interested at least it's worth a laugh, in the photo you will notice one of the blades have broken at the hub.

Post by: DHnut on March 07, 2019, 02:12:16 AM
Mike,
        That is a lovely model and it wants to fly. Looking at the video just after launch it appears to roll left as it is trying to circle right due to the right thrust giving the impression it is fighting the trim. I had a similar situation with a Hacker Piper Cub when I tried to trim it for a left hand circuit where the roll was opposite to the turn. Granted it is CO2 power. I get a straight take off and a climb that starts going right. If I tried to turn to the left it did the opposite to what your model does. with the right wing rollong right and the fuselage yawed to the left. It might want to fly right.
Hope I am not telling you how to suck eggs!

What they said ⇑ Mike,  and a lovely perpeller too!

That's fascinating Dave. Over one minute is impressive. I like the paper tube idea - I've been wrapping carbon tow round a paint bottle and wetting-out with CA - quick, but the bottle isn't a perfect cylinder which leads to a bigger than desired gap between blades and shroud. As you see from the attached pix, what I'm working on is very much lighter duty than yours. The Sorta Sukhoi is the flying surfaces of the chuck-glider I made, fixed to a balsa tube. Unfortunately the airframe has come out much heavier than I'd estimated. Had the model been the 20g AUW I was pitching for, it might have flown but it's 24g and a couple of low-powered chucks suggest it won't get much past a powered glide. I'll be trying different fan configurations but there's only so much oomph these little motors can provide when fed from a 2.7v capacitor. So I'm still undecided as to whether to embark on a scale Su-7 project. The good news is that I just flew the model in a stiff swirling breeze and it's very stable despite anhedral. Also the short span seems able to cope with the torque from the powerplant. The forecast says wind → → → → wind, so I don't know when I'll get conclusive results.

Stephen.

Thanks for all the kind words - despite the wind it is an encouraging start to trimming.

Looking at the video just after launch it appears to roll left as it is trying to circle right due to the right thrust giving the impression it is fighting the trim.

Ricky, it was hard to tell whether the model was fighting the trim or fighting the wind.  I'm setting it up to fly right-right - on the first flight it looked like that was going to happen.  I think on the later flights the wind was pushing up the right wing - the model looks like it is sideslipping.  I've seen similar behavior from the WACO after I trimmed it for right-right.  As Jack Plane said, I need less wind!

Hi Stephen, I think this little project is worth its own thread?  :)

... the bottle isn't a perfect cylinder which leads to a bigger than desired gap between blades and shroud.

This is one of the keys to efficiency with EDF.

I'll be trying different fan configurations but there's only so much oomph these little motors can provide when fed from a 2.7v capacitor.

I think this is potentially an issue. You want high voltage and high KV for lots of revs. You might want to try a higher voltage capacitor (weight penalty) but for EDF I think you'd be better looking at 1S lipo and a Peterborough timer. There are small set ups that would give you much more thrust at a lighter weight. I know fabrication of the parts is something you enjoy but I would consider a 32mm 4 blade 'Tiny Whoop' prop on a 6mm motor. Just over 2 grams weight and giving 10-12g static thrust.


Love the Wicko Mike!!!

Today was the last of the Peterborough Model Flying Club's indoor meetings of winter 2019 at Bushfield. As it was also the last Bushfield before the BMFA Indoor Nats and it has the same size flying area as Wolverhampton it was well attended.

My own KK Piper Super Cruiser seems to have survived  6 months in a plastic box and needed a only a few tweeks to get it back to its 'sort of ok' flying trim.

It was good to see so many Hippocketeers...is that the right word ? and catch up after the winter

Pete's PT3 made some impressive flights as did Mike's Redwing. Graham's Heinkel? was flying beautifully as well but I managed to miss every flight with camera  :-\

Great compilation Chris - encapsulated the session perfectly, and super to see footage of Pete's latest doing some very good aviation indeed.

Much frustration at my end as simply couldn't get the Gasparin 43BB to perform at all properly so - despite the four hour round trim - the Scout didn't get to fly!  Consolation was that, when I announced my intention to just bite the bullet and electrify the old girl in time for the forthcoming Nats, Graham immediately and incredibly kindly specced exactly what kit I needed and how to fit it.   :)

Good also to see so many of the usual suspects!  ;D

A very good day at Bushfield, and great to see those who were there. A lot of fun packed into into the three hours- definitely worth the drive for me! Thanks for all the help with the PT-3 (update on its own thread).
Sorry, forgot to take any photos, but thank you, Chris, for yours and your great little video is very evocotive of the session. The mass launch was pretty impressive for a club meeting. I wonder how many we had in the air at once?

(and thanks for lunch, Jack Plane!)

Thanks for that video Chris. Lots of action and a good coverage. Apart from the flying I was impressed with the efforts of the "catchers". One particular high catch would have done a basket ball player proud. Lots of fun and that mass launch was impressive. Good to see Pete's PT-3 starting to realise it's potential.

... it's the twice yearly pilgrimage to Impington this weekend.
You should all put your scale models down for a day and make it to Impington for the day (Sunday)! ... saying that, you could always display them!
I would love to see the event return to it's old level.

Post by: ffscale on March 11, 2019, 05:33:41 PM
I was very, very grateful to you Russ for saving the Redwing from hitting the wall - it was a truly splendid catch!  That was the key flight when my adding a little more side thrust had opened out the turn to such an extent that the circuit no longer fitted inside the hall!  For the the subsequent flight I added a touch more rudder, and hey presto, the model now circled consistently without the turn opening out as the torque rolled off at the end of the flight.    For the very last flight of the day I added an extra loop of 1/16" rubber to get more height.  At 600 turns it got up to head height, so as I can go up to 900 or so without it getting scary, I think I'll use this amount of rubber in April.

It was great to see the PT-3 in the flesh, and pleasing to see the flights improving during the session.

And Monz's D.VII is a thing of beauty - a stunning model.  Holding it (rather nervously!) it really doesn't really feel that heavy  - I can't imagine the wing loading is actually very high.

Thanks to Chris for taking and posting the videos  :)

I printed out three copies of the 3-view of the Puss Moth which I'll be making for Peanut Scale, but scaled to 50% (i.e. 6.5" span), then cut everything out and experimented with roughly positioning all the cutouts on a sheet of A4 paper.  The eventual drawing will of course be full Peanut sized on A3 paper, but the mini version is very useful as it helps me quickly play with arranging everything logically and clearly for the most efficient use of space and clarity of construction.

It looks like I can easily get three views of the fuselage (profile, top and bottom) arranged in a vertical stack on the right hand half, thus referencing one another without any disjuncture, giving explicit detail of the greenhouse quantities of glazing between the wings, and similar detail of the three-part u/c and three-part struts underneath, plus the differences in fuselage structure between top and bottom views.

The front view with a full wing on one side then sits on the same line as the fuselage side-view but on the left half of the page, with fuselage sections inline with it below the single wing (the slight dihedral of which helps keep these clear).  There's then plenty of room below it for two separate wings and more besides (e.g. detail of the proposed balsa prop and spinner, wheel construction, a possible perspective view of the fuselage bones, etc), and space will also easily be found back on the right-hand side of the page for separate tailplane and fin/rudder components.

With all this happily sussed, I can next tape a sheet of A3 paper to the drawing-board and start pencilling in main reference and construction lines.

Jon

PS - this really needs its own design & build thread, which I'll start after work quietens down in a few days' time when I hope to start making some proper progress... not that time before the Nats is short or anything!   :o

I got our and trimmed my Cessna Cr3 from the hummingbirdmodelproducts.com kit. Here are a couple of videos showing trimming flights. The final flight of the day was finally in good trim and she went for close to four minutes getting very high and catching a small thermal. This ship looks to be a solid two minute scale model that is very forgiving of poor launches and trim. It is probably one of the easiest scale models I have ever had the pleasure of trimming.

Spent a very enjoyable morning flying DLG's at Ivinghoe Beacon with Monz.

I had my Blaster 3, Monz a CX5

One of those sessions where I learnt a lot. The performance of the new top end DLG's is certainly a step up from my Blaster 3. The launch heights Monz could achieve was a bit of an eye opener too.

Launch settings refined a bit more thanks to Monz's help and model trimmed with both 30g and 60g ballast, actually trimming seemed to involve just screwing the ballast to the model :-).

 The wind was kind to us with W swinging NW so almost ideal for the best slope. The most remarkable thing was flying in the increasing wind up to about 15mph with 60g of ballast and how smooth the Blaster remained, very impressive. Monz's CX5 flew unballasted at 230g and penetrated better and has a bigger speed range, interesting to compare the difference

Great fun

Chris


Title: Re: What Did You Do Airplane Wise Today?
Post by: Monz on March 24, 2019, 11:39:48 AM
Yes, was great fun! Thanks for the invite Chris. I hadn't sloped in years.

The Blaster actually did very well in the conditions and I was surprised at how well the CX5 handled too at 220g. I wasn't launching at full power and it was straight into the lift which did help the launch heights. The thermals were plentiful, albeit in small bubbles being blown through quickly, was so much fun circling with the Buzzards.

Jon, you missed a cracker of a day! The Middle Phase would have been up and away too.

Post by: Jack Plane on March 24, 2019, 02:20:57 PM
I know, not only I'm such a loser but I evidently missed out on some great company as well!!!  ;D

Did however have some high-octane fun sloping the Go Mini on White Horse Hill before Sunday lunch at the local gastro-pub.  Wind direction was ideal for the NW-facing bowl although a little flukey - light with big gusts - but the thin wing, home-made ballast, and ability to alter camber made light work of the challenge.

Spent this afternoon soldering the Voodoo 15 motor to the Zombie flight-profiler and micro-connectors to the micro-charger and the 1S 130mAh LiPo, then completing the tray installation in my Peanut Bristol Scout (originally converted from rubber to CO2, now converted again!).  The very light weather forecast for later this week should be ideal for outdoor trims... I hope!  :-*  :-* weather gods...

Finally got the Hemiptere and the Doodlebug out in the yard for some test glides.

Very happy with the Hemiptere, not so much with the Doodlebug. With about 50 turns, the glide on the Hemiptere was very flat and gentle.  The Doodlebug was acting nose heavy. Removed some nose weight and no change. Removed some more, no change. Put it back in the shop to adjust the stab incidence.If we have weather like this tomorrow maybe I can get to a nearby field for some longer tests.

Reset the stab incidence a smidge and while it flattened theglide a small amount, now it has a tendency to fall off on a wing.  I have a feeling this is going to be a very frustrating plane to trim out. With all the struts it's very draggy, so likely speed will need to be higher.


Title: Re: What Did You Do Airplane Wise Today?
Post by: Dan Snow on March 30, 2019, 08:25:09 AM
I think the Doodlebug is destined to become a hanger queen. It weighs a porkly 60 grams, giving it a wing loading of .77 grams/square inch.  So here is my goal for this model. I will do whatever I can to get a decent 30+ second flight out of it.  At that point she will likely be retired. It checked off a box, I've always wanted to build one, and now I have it.

Please pardon the messy bench, I'm in the midst of another project for our Children's Museum.


Title: Re: What Did You Do Airplane Wise Today?
Post by: Rich Adams on March 30, 2019, 11:49:50 AM
Dan,
Don't give up on your doodlebug too quickly. I had an BF 109 that I built from an Easybuilt kit (30" span) The wings were too long for the scale so I chopped them off at the last bay. After many changes and using a hook to peg length of rubber of 54" I was able to thermal that airplane for 7 1/2 minutes once and took second in WWII mass launch at the Outdoor Champs in Muncie with it. Two minute flights were routine until I destroyed it. Wing loading?? 1.02 grams/sq in.

Thirty seconds and more is achievable. You'll drive yourself nuts chasing the wing loading recommendations that are possible with the best wood, a good design to make use of that great wood, and the patience and developed skill to built ultra light airframes. Your reward? Planes that are capable of flying away or are extremely fragile and may not survive a full season of flying. Until you get to that point, build and fly them for all they're worth cuz you'll never know until you try.

Plus, you'll develop other skills along the way...


Title: Re: What Did You Do Airplane Wise Today?
Post by: OZPAF on March 30, 2019, 08:26:43 PM
That's very good advice from some one who knows Dan. Have a cup of coffee and then come back to it. :) The model that are hard to trim are the one's that will teach you the most. Observe and remember exactly what is happening and in what order it happens, and how fast if is flying when it happens.
Eventually with a bit of luck you'll see a pastern and be able to adjust it for it's best performance.

Happy flying

John

I also ate primo BBQ today, good thing my cardiologist is not into airshows. He has me on one hotdog a year, no beer, and I can't say how he feels about BBQ, I feel great though. I have been eating food Mr. Ed would have liked for 3 years now!

But it is good some folk do because it helps maintan them for us meanies to watch.  I have been up close to the BoB Lancaster and was disappointed.  It is all gloss bling and modern gizmos etc.  But the other one l went in was much more original.

Finished "coloring" my Mooney M20C no-cal fuselage; project is ready for assembly.  Hand drawn markings and covering are complete.  just a few little details to be added, then final ass'y.  Used a Tombow art pen (#905) for the bright red/orange, and a metallic gold marker (Pen + Gear brand) for the accent color. Sharpie ultra-fine black pen used for control surface/window outlines. Windows are "chalked" with pencil graphite, then burnished with a cotton ball.  Elmer's washable (purple) glue stick to attach the tissue.  Just need to build up a prop and shaft , the motorstick is ready.  I may do a separate build thread, since I took a bunch of pics along the way. Built from my own plans/drawings.

Nice pen work, Indoorflyer  :)

I'm still working on too many projects, for too short a time. I have this growing notion in my head of getting 60 model aircraft in the air in the year after my 60th Birthday this August!
If anything, this is a great excuse to carry on my 'parallel build strategy'! .... and it's only just over one a week ....
If I make this for non-scale models too, I am not too far short of half of that total in models that are in or close to a flying state.

Every now and then I have a tinker with my 2011 Pistachio entry in the Indoor Scale Nats. It wasn't finished properly and took a few knocks on the day and since that time.
I realised at the weekend that I had never test flown the model with the nose block replaced with blu-tac. It actually has quite a nice stable glide .... it raises hope with me that it could still be a flyer with the right power train.

Also over the weekend, I produced over a dozen of these 90deg alignment jigs ... to hopefully speed up my production line!

FFM:
I don't think your work in the second picture counts toward the total of 60. Maybe you could do a few catapult gliders. They're lots of fun, and if you don't put in a dethermalizer, they fly away after a while, so you need a bunch.

Not long ago, I managed to get another modeler's intractable aircraft to fly by using a smaller prop. I realize this means stripping the rubber even narrower, and maybe your prop is already small. I suppose a bigger tail would have a similar effect.

Looking at that paint job, I can see you're more patient than I am.

Airplane wise, I tried to renew my [email protected]#$$%^! FAA registration* today, and, after some struggle, found out that it didn't expire just yet. Also went to a free flight club meeting with people who are much more motivated than me. We have a knowledgeable teenager who expounds at length about various scale issues and details he's discovered. Mostly, it's interesting. He and his dad build a lot, too.

Graham,
If you don't mind doing the assembly etc. then I can do little 'kits' for them easily ... I'll bring some to the indoor nats for you if that is not too far away?

Lincoln,
Yes, I do enjoy flying catapult gliders ... chuck gliders are a problem with my shoulders however. I've got a stock of sport models that never sees light of day .... I hope to kick start myself back into the enjoyment of flying.
I think it's the 'better put it back in the box while it's flying' nature of protecting my scale models that has caused this 'flying block'?!

Covering a wing with cellophane for the first time, an interesting experience. Since cellophane doesn't have any glue on it, and I didn't have any glue stick available other than the repositionable (Post It type) type, I took a chance and tested with standard PVA-based hobby/woodglue. Worked like a charm. :) I first diluted the glue with water, approx. 1 part water to 3 parts glue. I then brushed on a thin layer of glue on the surfaces I wanted the cellophane to stick to and let it dry for a day or so while doing other things. I could then treat the cellophane as standard covering film, attaching it with my trusty old covering iron and finally shrink it down to a drum tight finish. A surprise is that this material, although apparently stiffer than ordinary covering film, stretches enough to cover an almost square wingtip in one piece!

This cellophane, bought some years ago at our local Dollar Store is also dirt cheap, where one bag of 15 sq. ft. (2 sheets) came in at about $1, or three bags for $2! Who needs Oracover/Ultracote? :D If there is one downside to it, it must be that this film has the color painted on on one side, preferably you want this side pointing down so the color isn't worn away with time. And if you have to reposition the film after ironing it down, the color will be torn away, leaving a "blank" space. Only the future will show how well the cellophane/glue combination will stick together, or peel away with time. Also, it might not be as puncture/tear resistent as regular covering film. OTOH that shouldn't be a problem, since we're not supposed to crash, OK?  ;D

For several weeks I've been staring angrily at the damage on my rubber power sport biplane tossed into a dark corner of my 'den'. The damage was caused by me when I managed to release the fully wound motor without the noseblock and prop fitted...Aghhhh.

I decided, with not much better to do, to have a serious look at the wreck. As is often the case the damage was not as extensive as it first seemed. A bit of nifty balsa work and a major re-covering exercise and it appears to be fixed and not too wonky. It'll never be a contest winner but should be flying again when the conditions permit. Result. That's another addition to my fleet of tatty patch-ups.

I also had another attempt at starting my new (to me) .45 glow plug motor.  This is my first glow engine which I have acquired for putting in an R/C trainer as I am caving in and having my attempt at R/C later this summer. It's turning out to be a bit reluctant with finger flicking. Not like my easily started diesels that I'm used to. I've had her fired up a couple of times and it runs lovely (great idle and throttle response) but it takes some flickin'. I shall borrow my mates 'leccy finger' to see if I can actually get it to run when I want to fly. Caving in again!!!

WHAT DID YOU DO AIRPLANE WISE TODAY?

     I got in 13 flights  :o   today, Friday April 5 2019,  with the  30"  Rearwin Speedster - actually two flight reports in one -  6 flights and 22 pics in the morning, went home and had lunch -  and 7 flights in the afternoon and 12 pics.  We got our fill.  :)  The Rearwin even flew well when she was injured   :(   , the good ol' girl!   This session had everything, ...   trees, stuck in trees, trying to climb a tree,  broken rubber, two severe crashes, flying past tree trunks,   ???   etc.  But we got it all in before the Cricket guys took over.   :D   Here is a couple of the better pics.  I will post a full flight report later.

Had a great time at the Spring Opener in Gainesville TX in spite of the iffy weather forecast.  Saturday morning was a complete washout, but after lunch the rain stopped and winds died down for a couple of hours, enough to do a bit of trim flying.  Sunday started a bit dreary but turned into a very nice day for flying.

With the large field area I was comfortable trying a bigger motor in the Wicko - put 15g of 3/16" rubber (2x31" loops, 25% of flying weight) in the model, wound it to 5.5 oz-in (~1400 turns) and got a 2:56 flight.  This is my first max (over 2 minute) flight in FAC competition.  Had several other very nice flights on lower winds.

Video at:  https://www.youtube.com/watch?v=kcU7P3Q2AB8 (https://www.youtube.com/watch?v=kcU7P3Q2AB8)

Also got some good flights out of the Waco SRE, Little Gem and T-28.  The field was beautiful, with fresh green grass and lots of wildflowers.

It's a little known fact that crashed models left alone for some time after the incident partially repair themselves. I encourage everyone to put off throwing away crashed models for at least a week.

I've always been amazed by people who can consistently start a glo motor by hand. When I flew glo, I always used a starter.

Thanks John - when the weather cooperates Gainesville is a great place to fly.  The Wicko's glide needs a bit more tuning, hope to get rid of the pitch oscillation without killing the float.  Maybe I can get rid of that little blob of clay on the tailskid.

The technique that worked for me was to flick them backwards against compression but not through peak compression. They will fire and reverse direction and what is more the prop nut will not come loose. The inertia of the prop tightens the nut. Take care to ensure your finger is near but not at the tip of the prop and can slide off when the engine fires. The engine should be well but not overly primed and the glow plug hot. Worked every time for me on 40+ engines.

Mooney M20C no-cal finally finished.  Will have two propeller assemblies, a built up/formed balsa-blade indoor style, and a plastic bladed freewheeler for outdoor use.  Have done glide tests (sans prop assy), and with nose ballast, it comes to 6.3g without rubber.  Very pleased with the nice flat, straight ahead glide tests. Angled motorstick gives a little bit of downthrust, but +/- changes if needed, can be tweaked into the bearing/prop hanger.  Midpoint of the hook to hook rubber span is over the wing spar, which is the C of G.

This little model is a tribute to designer Al Mooney, B1906/D1986, whose birthday is Friday April 12.

I'm thinning the herd. I boxed up a bunch of 1/72 scale airplane kits and will ship them to a friend who builds like crazy. He averages 1.5 kits a week. His "airmada" is at #398. All of them 1/72 airplanes.  I sent him this picture as a tease:

Made my first plaster of Paris mould for indoor radio Percival Prentice.

I used the original vac formed wheel pants from the RC short kit which weigh 28g each.
The plug came out easily from the master with just one wipe over of release glaze.
Hoping to vac form the new Graupner Vector board material over the plug and get the final weight down to 3 or 4 grammes.

Next job to finish the vac box.

I have just got back from a visit to the new VMC unit at Flagg, which is a village just outside Buxton where I live. Only 10 minutes drive so very handy for me. They don't have a proper shop but are happy to sell to any members of the public who call in. I had a tour of the production area as well as buying some supplies. Phil showed me the parts for one of Andrew Darby's designed Hurricanes being laser cut which was fascinating to watch. One of those things that you could watch for ages. I think I will be calling in regularly in the future.
It's very encouraging to see a small company like this doing well, and they seem to have lots of plans to expand what they do. All good for our hobby.

Today I mucked around with this electric Sea Otter mockup, in a perishing east wind - but at least there's some dry ground, and sunshine at long last. After some flights with ever increasing propeller blade pitch being indicated, I made a bigger prop (the one fitted) and flew it at 40° blade pitch angle but the breeze was making for pointless roller-coaster flights. The wind ought to die down this eve according to the forecast.

The model is to 1/32 scale, or 17.25", 438mm span. It has an 0820 coreless motor and a 10F supercapacitor, and is geared 5:1. It's a bit disappointing as it looks like it might struggle to do even 30 seconds, and a scale model would be heavier and draggier with thicker flying surfaces, paint, details etc. The gears mesh very badly and despite work to clean them up I think they still sap a lot of the motor's power.

As for other supercap delvings; I gave up on ducted fans - I made some useful improvements but I think Jon (Y52) is right that at least a continuous 3.8v would be needed to get a small jet model to fly. I found that a direct-drive high-wing model I made was benefitting from a bigger prop with higher pitch, when it hit one tree too many. I hope to make a direct-drive scale model soon.

     Not totally sure how I got into this mess but suddenly have the urge to find Rearwin Speedster material. And there is plenty of it for a plane where so few were actually built. Just ran across a plan for a rubber scale 1in to the foot (32 inch ws) version from a designer by the name of Stephen A Lambert. The only other  reference to him that I can find appears in Model Airplane News, July, 1957. He published his Puss Moth (1/2A gas) which was also a 1 in to the ft scale. The Rearwin plan is dated 1985. His plan looks like art to me. I am hoping someone can tell me where to find more about him.

Here is a look at the Stephen Lambert plan from Model Airplane News, July, 1957. I'm interested in finding out more about any other designs he drew between the middle 1950's thru the middle 1980's. Again, I found a 32" rubber powered Rearwin Speedster plan but am still interested in finding any others that might be hiding in the shadows somewhere.

BAT Monoplane ready to cover: presently 11.5g. Based heavily on Al Backstrom's dime plan, but enlarged to 1/14 scale/ 19" span. Should end up sub 30g with 450cm2 of wing area, so a nice slow flyer.

kennybflyin,

I had some correspondence with Stephen Lambert Jr. in 1984 when I purchased his own version of the D.H.80a Puss Moth plan, somewhat different from the M.A.N. plan you have posted.  The M.A.N. version appears to be a redraw of Stephen's original.   At that time, I thought the model was a bit beyond my abilities though I could probably deal with it now.  His surviving letter describes how certain features of his model were made and he kindly provided a pair of Union Flag decals that he had printed to adorn the rudder of the Mollison Moth The Heart's Content which he modeled and flew in the 1957 Nationals at Willow Grove, PA.

At that time (1984), Stephen Lambert had a model airplane plan business called I-II-I M.P.Co. (One to One Model Plan Co.) which inferred that his plans were to the constant scale of 1" = 1'.  All of his plans were free flight scale but the power source could be rubber, CO2, or IC engine.

Plans listed include:
Fokker D.VIII
Gull E (1941 designed semi-scale)
D.H.80a Puss Moth
Dormoy Bath-Tub
Great Lakes 2T1A
1935 Corben Baby Ace
Evans VP1 Volks Plane
Wittman Buttercup  (I have this plan from July, 1958 M.A.N.)
Les Long's Longster
Pietenpol Sky Scout (Single seat predecessor of the Air Camper)

At that date (1984) he was working on additional plans of the Demoissele, Luscombe Silvair, and the Berliner Joyce P-16

Mr Lambert also mentioned that pre-WW2, he was working as a Sales Representative for the Comet Model Co.  In 1984. he was living in Greensboro, North Carolina.

Mark,

     Your list of other plans drawn by Stephen Lambert is exactly what I was looking for. Now to find them and add them to the Rearwin Speedster plan. Maybe we can get permission to share his original plans which apparently have not been published. If the Rearwin Speedster plan is any indication, his work is true art.
 
Again, thanks for your reply.

Kennybflyin

Cracked it! At last the wind was absent this morning so I got a few flights on this Sea Otter mockup. It has gained a new even bigger prop in the meantime and after a ≈ 30 sec flight without much altitude I fined the blade pitch to where it is in the attached photo and the model flew for the camera (https://youtu.be/HgABXMO8UWg). This is an early flight - I expect I can milk more out of it, but this is the steady green light I needed before I'd have considered going to the trouble of making a scale model. The noise is off-putting. The screeching gear noise is horrid close to, but the camera mic. does exaggerate the sound a lot. And they say you can get used to anything. . . Further away and at lower rpm, the uneven meshing of the gears makes it putter like a Model T Ford or something.

Note: the supercap is overboosted. Sonex413 recommends 3.1v max but after a real dig into the 'net I found. . .nothing. . .except one brochure that suggested quite strongly that 3.5v should be acceptable. Supercaps are known for their overvoltage sensitivity, but exactly how, how quickly, and how much they're affected is complex. I'm charging from three AA alkalines and measuring with a multimeter. With new batteries the charge only takes a few seconds, and you need three or more hands, so I'd better say the charge in the video is 3.5 +/- 0.2v, that should cover it.

Stephen.

Amazing how such an ungainly looking biplane flying boat could fly so well Stephen. Enter it as it is a scale model of Mitchell's proof of concept model :) Well of course he made one didn't he?

The gearing and the prop are very effective.
