How to respond. You are creating a hangar full of incomplete models :(

Complete to the point of maiden, else none are eligible for the sweepstakes

Yes, the models seem innovatively put together, but the proof of the pudding, as the sage said, is in the eating

If it is because you don't have electronics yet, that is really unfortunate. Most of your builds seem airworthy

I am borrowing some elctronics from fellow modellers. By the end of may, as my paernts promised, I must be able to get two models airborne..

Winglets are unnecessary for a model of this size. If, however, the purpose is to keep a scale look, you could extend the spar by a tiny bit and then stick an externally cut winglet with a slot in between so that you can attach it to the spar.
