The OP didn't state what model Dewoitine he has. If it is a D.520 a standard servo is nothing I would use. If it is something like the Emile Dewoitine A standard may work just fine?? I wouldn't use standard but years ago a 48 in. lb. servo worked just fine on a lot of giant scale models. It's also when we started ganging servos together on control surfaces. If the OP went to a site like servo city he could look at better servos then standards and see the prices. We just have so many better choices then standard servos today. I personally use standards on trainers and there like. My other planes get the best I can afford.
