What would be the recommended servo torque for the control surfaces on a 85" to 100" WWII fighter? I personally split all control surfaces (two for ailerons , two for flaps and two for elevator) and use high torque servos (77 in-oz minimum). I also use a 6 volt system which boosts the torque even more. Is this way over kill? Am I wasting my money here? I see many people using standard servos and 4.8 volt systems......
