Yes I used both rudder servo's to help balance the bme 50. It is still a smidge nose heavy but flies very well. You will need 6 high torque servos for ailerons rudder and elevator and 1 standard servo for throttle. make sure to keep all radio components 10+ inches away from the ignition components by using a nyrod or similar from throttle location to motor. You will only need a switch-charge jack setup for the ignition to turn it on and off and charge the ignition batt. Just like glow just set the carb to close all the way to shut it off triggered by a switch on the transmitter. If your going to fly IMAC with it I believe an additional kill switch is required. You will LOVE the power with this combo
