Some other questions. Do i need an extra servo for the motor (like gas)? If yes, 4 all together (throttle, elev, rud, ailer ???) Micro 9 servos will do i hope... do they go w/ my reg futabe reciever? or do i need a new one of those 2??? :| Once, again, im pretty new at the electric, so plz forgive the dumb quiestions
