Charlie,

When I shortened the nose on my Bipe, I added ailerons to the top wing. In fact I did it without removing the covering. I hate covering! The flight characteristics are quite different, obviously roll rate is much improved. The full scale Bipe was not necessarily supposed to be an aerobatic demon and the kit version is representative to the original design. I just wanted more roll response. I found that the rudder could over come the single set of ailerons in certain situations. Very strange maneuvers resulted.

Good aircraft. You will love it.
