Hi guys -

Not sure if this is OT, but my latest is a 42" Kerswap, converted to RC and using an electric motor.

 Grin  well i've just finished four days of demonstrating model building at the Saint John Exhibition where i built a lysander and did a hurricane at home.

|I also built for display a Harvard ( texan to the Americans) , a Grumman Avenger and a mosquito in squadron 410 colours

i was asked real nicely to build a T-33 for the Flight Simulator Group of NB which I am gonna post here.  This is the Bluebird. there are 4 shots of it.  i will be building two more like it
i posted my AVENGER IN forest PROTECTION COLOURS this is the last of the 12 avengers NB had for fighting fires and it was sold and sent to SHEARWATER ns for repainting in WW2 RCN colours
I POSTED THE MOSSIE WHICH HAS SINCE BEEN DECORATED. it will be part of the Saint John air museum at Milledgeville.
I have two more hurricanes to build which will be done to commemorate the three pilots killed during the Battle of Britain who were from this area.  More on that later.

I also will be doing a Spitfire for a retired air force vet.  when it rains, it pours.

FROG "Heron".

Started the build for the FROG "Senior Series" cook-up on SFA some time ago and finished last night (except for gluing the "glass" in) for the "Finish what you've started" C-U.  Weight is 18.6gm (incl "glass") w/o rubber.  The model came out NOSE HEAVY Shocked, necessitating a lighter Peck prop (6") instead of the IKARA I wanted to use (2 vs. 2.74gm).  I'll be doing the test flights with 4 strands of 3/32nd.

Thanks Tom.

The wind we've had died down to a reasonable level last night at 11, so I cranked in about 40 hand turns and let it loose from the entrance stoop (the wading pool had been emptied and moved to the corner of the yard).  The model showed a very slight left turn tendency (no bank) and hardly any sink as long as the prop was powered.  When it went into fw, the glide angle DID steepen noticibly, ending the "flight" just short of the wall.  Prolly a bit over-powered and in need of a thrust tweak.

Looks like it might be a good flyer.

Here's my latest project... The Baby Bipe from George Wilson...build thread in Indoor section....

Fun little model spurred by the mention of this plane in Flying Models Magazine FreeFlight column... from an old American Aircraft Modeller Magazine plan.

I finally got around to working on an airplane.  This time it's my fourth refurbishment of my electrified Peck One Nite 28.  In the end I only actually kept the wing's frame.  Everything else was worn out and needed replacement.  I managed to knock 7.3 grams off of the weight taking it from an even 50 grams to 42.7 including prop, motor and 160 single cell lipo. 

It's using one of my own electronic controllers and dethermalizers.  The D/T drives a Spektrum linear servo which pulls a wire to release the stab.  A spring pulls the tail assembly up 90 degrees.  This was just like the previous incarnation and when it D/T'd the airplane would tumble end over end bringing it down rapidly. 

The covering is 11 g/m^2 Cuben on the bottom of the fuselage, the center section of the wing and the bottom of the stab.  The rest of the fuselage is covered with Risteen Microlite and the stab/fin is covered with 2.2 g/m^2 aluminized mylar.  I added strips of Japanese tissue to reinforce it.   The tips of the stab and fin are painted with flouerescent orange spray paint to help me spot it in the grass.  The top of the wing is 2 micron mylar laminated with pieces of Japanese tissue put on with Future floor polish.

Well, I just happen to have some swanky new F1G wings here that might get the treatment if I find the airplane comes underweight by a gram or two.  I have to be careful, though.  Our airplanes occasionally draw the attention of a local bird of prey.  I'd hate to have it mistake my wing patterns with something it might find tasty or attractive.

Climber....

A little detail of the tissue application on the wing, please.  Are these overlaid, or something else?

Love the look...

Hey there;

I started with 5cm x 5cm patches of red, yellow and orange Japanese.  I applied these to the wing using Future Floor polish in a random but non-overlapping pattern.  Some of the patches touch but I was careful to make sure that the other edges were not lined up. Some of these patches hung over the edges and were trimmed off. 

I then filled in the rest of the field using custom cut patches of green or blue tissue applied so that no two patches of blue or green touch.  All of the patches touch edge to edge and none are overlaid.  It's as slow and tedious as it sounds. 

The black edging is to act as a border and to help keep the patches in place.  I've found that the tissue can delaminate on the edges if I didn't do a very good job of applying it.  The black tissue is wrapped around to the bottom of the wing.   If I didn't want a black border I'd just use white instead which turns more or less invisible when applied. 

The grain of all of the patches is alinged with the wing's span.  After application I clamped the wing's sections down to my metal building board with little magnets and then ran over the upper surface with a hot (160 - 190 degrees C) iron to melt the Future and "cure" the adhesive.  I hold the iron a mm or two over the surface as the Future will smoke and stick to the iron if it touches. 

Besides curing the Future this last step also "fixes" the shape and helps eliminate warps and ripples on the leading or trailing edges. 

I did the same with the wing's outer panels except I clamped the leading and trailing edges to pieces of square steel tubing where one end of the tubing is raised a little to add some washout.   You can see how I do that here with my Art Chester Goon's wing:

http://members.shaw.ca/ffdude/images/ffgoon004.jpg

Besides resulting in a reasonably strong and puncture/warp resistant finish it also relatively light.  The finished wing weighs a around 14 grams.  I used the original kit wood.  If I rebuilt it with lighter wood I could probably take a gram or two off.

Craig, I take it that there is a base of either plastic (mylar) covering, or Esaki tissue.  I definitely like your work.  I am partial to "different" covering schemes from the run of the mill ones of two or three colours.  Maybe I should make one of my Gollywock wings in a similar manner as you.  I just like different.   Smiley  Caley

Hi Caley;

Yes, the base is mylar.  In this case 2 micron clear mylar which I bought from homefly.com.  I stick it to the wing with Sig Stix-it.

Craig,
Any tips on how you 'handle' the 2 micron Mylar as you go about covering your structures would sure be appreciated.
I've only tried 5 micron/ 1/4 mil stuff and had some 'handling' issues.

TIA
