I have a three channel futaba radio with standard servos (43oz torque) my question is will a tower hobbies trainer 40 fly on rudder, elevator, and throttle. I know its better to start with 4 channels.But I already have this radio and would like to try to learn to fly on three channels.I know I will not be able to perform stunts but thats not what I want to do .any input would help.
