if you run lots of drag brake some, or all i have tried, digital servos do not like the throttle, but 9550 is way fine for the 710... i have been using the same digital servo for steering for over two years.. it is much faster .08 but only make 89 oz of torque for steering and it is a none issue on power and funtion.. throttle I like lots of speed but having about 100 oz is maditory for my braking style..
