Keep it simple, during construction just cover the sides with .2-.4 oz. carbon veil.  To do a better job don't taper the fuselage- round the edges and maybe taper the canopy, but leave the main sides intact.  Prop the fuse up on a brace, about 8 inches off the board. After applying the veil clamp it with a thin sheet of builders poly sheeting, no more than 4 mil thick.  Make it 2-3 inches larger all around and hang weights around the edges(get a helper).  You can also use rubber bands down to screw hooks in a base.  It doesn't take a lot of pressure.  Before the epoxy dries ( I use West Systems 2hr) gently push any excess epoxy to the edges and wipe it off.  Make sure the plastic is pulled down smoothly.  Let it cure, clean up the edges, turn it over and do the other side.

You can just spread epoxy and squeegee the veil in place.  A bit heavier and it will require more sanding and filling, but it will stiffen the fuse the same way.

I believe that Joe tore the outboard wing up/off at Brodak's.....fixed it and it STILL flew great!

 Didn't he end up winning Brodak with it?

 Joe,

 Just out of curiosity, how many flights would you estimate the T-6 has on it?

Perhaps (though, my experience refutes that) durability is an issue for a single surface material, but not for a properly applied composite. My Baby Super Clown is wrinkle free after a couple of years. Try the technique on a junker, let it age, then criticise! If you ain't tried it, you have no valid standing. Others have used the technique, as noted, and say it is durable.

I really get anoyed at those who post "well I don't really know, but......"  Head bang

Incidentally, iron on films are NOT a shrink film, but a stretch-on material! Applied correctly they look tight before you ever touch them with a heat gun. Get Faye Stilley's books and learn how to do it right. I did a Monokote demo for our club. One wing was pre-covered and a member was very impressed. I said "I haven't shrunk it yet!" That's how the job should look if you want it right!  y1

Learn how to do it right before saying it is no good.

Finally started on the wing today. I had to take 1 1/2 hours just to set my work bench up to start the wing build. So far no problems. I wanted to use my wing jig but the rib cutouts wouldnt allow me to. All good though. Followed the instruction book and building is going great.

Excellent idea Brett.  The only change required is to put an addition in the PA rules that if a pilot(s) flies a plane he did not build, per the general rules, they do not get appearance points, same as the skill class  rules.

Another possible quibble, which I didn't see mentioned, is that some folks do not like it when the judges see a broad range of skill in the same flight group.  Apparently they think this might have some unspecified effect on scoring.

John,

I like your Bipe.  Did you see Disney's 101 Ringmasters?

Phil,

This is the Sterling Stearman, designed for R/C but had some CL detail.

Dennis in lieu of what Larry posted, I should have told you that my original intention was to paint the Ringmaster after applying and doping the Silkspan.  At the last minute I decided I wanted to do a color scheme with the plastic film and that is when I ironed it on.  The point I was trying to make if you DO dope the tissue whether it be Silkspan or Polyspan, the plastic film will stick to it.  I have no idea how much additional weight the dope added but the plane flew very well with an OS. LA 25 on it.  Mr. Renger is right, there is no need to dope the Polyspan before you iron on the covering.

This was one of my more enjoyable builds:

For what it's worth, here's a link to the details on Yellow Jacket, a Shoestring Formula I Racer built in Florida in the 70's.  It is a little different in cowl shape etc than the original but was reportedly faster also.
