Yep, it's a Jr. Flitestreak...I had one with a Cox .15 TD...HOT plane! But it had a thick airfoil, and I don't see how anyone could get the wrong wing incidence...it slid into a slot in the fuse. It actually looks fine to me. But then it shouldn't require down trim to fly, so something is wrong. It should require very slight up trim, if it is 0-0-0.

I agree those ailerons are not ideal because they are so narrow at the tips and wide near the fuse. They were usually fixed, but could be set up as flaps to operate opposite the elevator, to give tight corners on square maneuvers. I'd be tempted to cut them in half and fix the inner half and use only the outer half for ailerons. As it is, aileron deflection is probably causing more drag than turn.

Still curious about the weight, and also the CG. You might have to come forward a little more because it's got a big wing, a little stab, and a short tail moment. That's a recipe for pitch instability.

With the CG far forward, you'd better be ready with the down elevator if the engine quits. The plane will tend to quit flying too, so get the nose down and keep up the air speed.

Keep us posted.
