RE: TF 1/5 Scale P-51 ARF Assembly Thread
There is not a problem, they just need strong servos to hold the flaps down. The 615's will work fine on the ailerons. The ailerons need at least 80-90 oz. and the elevators should have between 90-120 oz. each. The rudder is the same. This depends on what you are going to do with the model. If you are going to fly it like you were in the aircraft, that means no nine G turns or pull ups etc. You should have no problems. Also if you don't use flaps on landing expect the plane to float forever in ground efect. The barn doors will really slow her down and shorten the landing roll. Just my experence with mustangs. Hope it helps.
