360mm dia prop, I plan to start with 660mm pitch. What size of motor should I use for Cat II?

Thanks Lincoln for that very detailed reply.  I have built 5 more kits after that first one and I'm slowing learning how to do it.

It's great to have folks such as yourself who take the time to thoughtfully write up their suggestions.  It is what makes this such a great forum.

Best,

Dan

David,

The Midkiff Besson’s been done: Simon Rogers:  Kit Scale, 2016 Nats.

Flew nicely: just needed more poke.

The KS rules allow you to move the motor peg forward for rubber as well.

How odd.  One of those URLs isn't rendered as a link.  Try this: Capt. Neville attacks from the sun.

  In position ready to bend up the float struts, I think I'll need lots of wire!

    Your DVIII is looking quite smart Don.
Been working on the floats for the WD 11, pretty straightforward, I chose some quite hard balsa for the lower sheeting back to the first step for a bit of durability. The struts attach right on the top edge of the floats so I bent up some 3/32" alum. tube in a "V" so it could mount over a wider area on the bulkheads, the tubes were then sheeted with balsa to fix them securely. I cheated at the rear of the float and used some filler to blend in the rear keel.
     Next I fabricated a jig to hold the float in the correct position relative to the fuse.

Agree with all the other comments David:  beautiful SE 5!!  And a great comment OZPAF re tross's cowl:  weighs the same both ways............ Grin Grin

I added some 1/32 strips here and there to either side of the stab 1/16 sq frame, then sanded to a very modest symmetrical airfoil.

Maybe Monday or Tuesday for trimming - as long as it's above 40 degrees and a light (3-5) wind...I had a dream about building a Ted Evans Vansteed last week and it is starting to bug me...got the plan out and read all the material I had from SAM-35...what a SWEETIE!!!

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

Thanks for the tip Tom Arnold - sounds like the bath tub water works ... yeah watch out for that Plumber's bill ...  Undecided
     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 )    Cry   , 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 ...    Shocked

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 !!    Roll Eyes     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 ...   Smiley

PIC #   8618  One pic of the final result.

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.

Those fillets really set off your nicely covered model Sciggs. Fillets along with prop carving must be one of the milestones of model building.

Thanks Richard and Crabby. The toothbrush idea is a good one - no hot tub available I'm afraid.

Bob,

Thanks for posting the link on you block. Never used openSCAD before, downloaded it and your script and was able to make changes. I then did a preview, then rendered, then the STL file . Is that the correct steps?

Not exactly sure what you are concerned with John.

If you're talking about the link to this fellow's web page there's nothing unusual about it. There's lot's of links to web pages outside of Hip Pocket Aeronautics and you are right, they are not 'connected' to us. Bob M is simply providing a way to get the script he created for doing a 3D printed form for making a prop.

The PDF he has linked to is a copy of a magazine issue that he found helpful.

Regarding cookies and click here things, that's all about personal preference and doing what one is comfortable with. I personally allow cookies for the simple reason that I make the choice to go to the web sites that I choose. If I willingly go there, why would I block the cookies for those sites. I have my browser prefs set to not allow tracking cookies and so on. I also go through the cookies once in a while and get rid of the ones that appear to be from advertising servers and such. Believe it or not, cookies are good thing for the most part. Like, without the HPA cookie you are forcing yourself to log in every time you visit. (what a pain). If you allow the cookie you would be automatically logged in because the site would recognize your computer.

Apologies to Bob M for getting off course here. As soon as John acknowledges my response we will delete these two posts.

Saw a few that interested me at the retro rc site.
Any other sites offering a kit?

My Hillbilly thinking went to a Guillow's HLG lying about, spare rubber bands, and woodland sticks.....
or just recalling being a kid again..lol

HLG at a birthday party were given out as party favors by Billy's "Crazy Uncle Ted". He taped pins to the nose and made games of pop the distant balloon. Winners received rubber powered stick and sheet airplanes. After the B-Day Cake he cut nose notches in a couple HLGs and launched them with a homemade slingshot.

Hi David! Yes you can modify the model's power source and (I think) the wheels. That's about it, though! No sneaky lightening of the structure or other such underhanded tactics... Unless it's invisible under the tissue, of course! Not that we would stoop so low, of course!

I won a little Guillow's Skyraider kit in the Nats raffle. I am giving it to one of my NCMAC pals as it's one I will never build. I know it was a great aircraft and beauty is in the eye of the beholder etc., but I've always thought it was one pig ugly lump! Sorry...Tee hee.

Cheers,

Dan.

Thanks Richard.
I'm taking it very steady with this one because I don't want to mess things up by trying to go too fast. Today saw the chance for some outdoor test glides. I'd balanced the model pretty much as I would for a radio model and had done some quick checks by gliding it onto the bed - while the wife was neither looking, or in said bed.
Outdoors the glides were straight and with gradual sink to a point about 25 feet away where the model ran out of momentum and flopped gently into the long grass. All very promising.

Hi Ricky,

Like I said, the main thing that put me off the Staggerwing is my desire to modify the u/c to the fixed and spatted version. For Kit Scale, if it's not on the plan, you will get hammered by the static judges. I will get round to it eventually; but just for fun.

Cheers,

Dan.
