Hi, what size of servo do I need to use on this plane on the retracts, rudder and elevators. the manul calls for standard servo. I know that I need a low-profile on the retracts but what size would be the best. How do you size a standerd pre what size of plane? When alot of manuals for differnt size planes state standerd size. This is the plane need sizes for. I just bought this plane from FlyBoy Models. They hade very quick service.
