The theory of using 2 servos per wing is that with high torque servos you get positive control with no deflection while pulling some manuvers. When using 2 standard servos, you can still get away with flying the plane with some 3D capabilities. That's my thinking on the whole thing.
All of the other 50cc Yaks out there are using one digital on the ail. I"m wondering if they have a weak aileron so they need to pull from two areas
