RE: Piper Cub Question
The Great Planes Cub .20 uses full length strip style ailerons instead of the more scale-like barndoor ailerons. Once off the ground, it's like flying a trainer. The turns are still prettier if you use the rudder along with the ailerons even though it can be flown with aileron and elevator control only. This is also true of most airplanes, even trainers.
I think that Great Planes .40 and .60 Cubs use the more scale like barn door ailerons.
