AmpFlow Motor Speed Controller


Motor speed controllers get connected to your battery and your motors. Your radio control receiver also plugs into the motor controller. The controller is then able to control the speed and direction of the motors.

The set-ups for the controller is simple plug-and-play. You can fine tune some of the parameters, but in most cases you won't need to. Our controllers operate two channels independently of each other so you only need one controller to drive and steer both the left and the right wheels.


The AmpFlow Dual Motor Speed Controllers operate at 6 to 36 Volts and can handle 160 Amps per channel. They feature adjustable braking, acceleration, and current limiting.

A BEC (Battery Eliminator Circuit) provides a 5V power output for use with radio control receivers or other devices.

Two mixing options are available. Each joystick can operate one channel independently, or a single joystick can operate both channels for tank-like steering.

Over-current and over-heat control logic prevents meltdowns and provides the maximum current even under stalled conditions. The maximum current limit is adjustable.

The 160A controller measures 7.5" L x 4.3" W x 2.2" H. Weight: 1.4 lb. Note: This controller has been updated with a metal case rather than the plastic case in the above picture.

Additional features:
*   Both channels can be combined into a single channel with 300A output
*   Additional third channel for low-current switching of auxiliary device
*   Inputs for two quadrature encoders for full servo control
*   Two servo connectors plug directly to an RC receiver
*   Adjustable current limiting
*   User selectable servo feedback: Encoder or Analog voltage
*   Full RS232 serial command and setup
*   Multiple-operating modes: Normal PWM, Torque, Velocity, Servo-Position
*   Manual control inputs (Step/Dir) for each channel (Left, Right, Aux)
*   Robust signal processing for smooth, reliable fail-safe operation
*   Indicator LED's show direction, power, over-temperature, and board status


Speed Adjuster


This speed adjuster plugs into the radio control inputs of the motor controllers. It is a quick and easy way to send the 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 of both channels.
