RDFR Speed Controls are used in bomb disposal and Combat 'bots to perform the "speed, direction and steering functions" all in ONE controller box, for both the right side and left side powertrains. These vehicles are powered by separate electric motors for the right and left drive. Also for Twin Screw boats combined with physical rudder for manueverability. Only two R/C channels, one to command throttle speed and direction, and the other for steering. Each RDFR unit has two forward / reverse speed controls coupled together. When used with a spring centered joy stick, HANDS OFF is stop, UP stick is straight ahead, and DOWN yields backwards. Pure right or left twirls the vehicle as the motors turn in opposite directions. In between stick positions are completely proportional, including reverse. Independent modes are also available. Compatible with DC PM brush motors and most model R/C systems, including Futaba.
