As far as keeping resin out of locknut or nutplate threads while you're glassing, you can stand them up in a row on some waxed paper and melt canning paraffin or candle wax into the threaded parts before you install them. Resin will not stick to wax. After they are in place and the resin is ha

Hello all, I?ve got two questions. First, what size piano hinge is used for the ailerons? Second, how are they attached to the false spars? I?m looking at countersunk bolts into captive nuts flexed onto the back of the spars, but my 1979 version of the plans doesn?t say anything on the subject.

Load is not just a function of airspeed it also depends on size of the control surface (among other things) 200 mph of an small R/C plane is not the same load on the control surface as 200mph for a full scale airplane. As I mentioned earlier, R/C gliders use "KEVLAR" for this purpose. I don't know

I dunno, but it's not for me to argue with the bright boys. It just seems that in rapid entry of a steep turn, one wing is trying to lift the airplane while the aileron on the same wing is trying to push it down, quickly. This seems like a pretty good "shear" stress on the edge of that .016"
