RE: WACO YMF
Edwin,
Most people bevel the Aileron and hinge it in the middle. Scale would be hinged at the top (barn door fashion) and that is the way mine is going. I have already seen that there is adequate room to mount the servo on its side. It will have to go right up against the forward sub spars to do it.
