rcmigpilot, I too am beginning to wonder at some of these recommendations. 4131s and 4721s have been used in 3D 60 size helicopters for many years, with good results; and you cannot convince me that a nine-pound plank, regardless of what engine it has or how violently it is flown, is going to be harder on those servos than a ten-pound helicopter being thrashed by some of the heli community 3D hotdogs.

The JR 4131 servo has a record of quality and service that some of the recently popular (such as Hi-Tec) can only wish for; ditto the 4721. and if you think 120 oz./in. isn't enough rudder servo for a light, 120-size airplane, just what IS "enough"?????
