This speed adjuster plugs into the radio control inputs of the motor controllers. It is a quick and easy way to send control signals to the motor controllers without the need for an RC transmitter or receiver. Turn the knob to control the motors from full forward to full reverse or anywhere in between.
One unit can control both channels of the speed controller by sending the same signal to both channels. Two units are required to have independent control of speed and direction on both channels.
