I recall flaperons being used first in U control stunt aircraft. Basically they allowed the airplane to turn a tighter inside or outside loop in addition to abrupt manuvers. When the elevator goes up pushing the tail down on the CG axis, the flaps go down pushing up on the axis. The flaperons can be used for the same basic principals for 3D or pylon racing if the pilot is willing to carry the additional weight of another servo for the wing. You may also use the flaperon system as simple landing flaps with a little more programming. ENJOY
