Standard servos are fine for everything except I would use a high torque on the rudder. Mine (powered w/OS 1.20) wouldn't hold knife edge til I put a high torque on the rudder. Consider a pull-pull setup too, easy to install in this plane and probably better for wild flying.

Really nice plane, but I sold mine recently to go bigger. Be careful handling the wing. That 1/16 sheeting won't take much abuse.
