More info


MGM X3-SERIES controllers are made to order. Options are also available upon request.

The X3-SERIES is the result of over 30 years of experience in ESC development. The newest ESCs are designed to be pushed to the limit = that's when they are most efficient. Just turn on the Keep-the-Limit function and break the records! X3-SERIES controllers have a much faster PC connectivity with our Controller 3 program finally available on Apple devices.

Successor to the now-legendary 40063 X2-SERIES, this ESC has grown by less than 1 inch in length (25mm) and added over 6kW of power - quite an impressive improvement, isn't it? Tried and tested in speedrunning, bashing, and high-speed RC boats!

Designed to be pushed to the limit!

For those who like to operate at the limit, there is a new parameter called "overcurrent behavior". In the MGM CONTROLLER 3 app, you can choose from 3 options for how your controller behaves when the current limit of 500A is exceeded. Of course, you can set your own maximal current limit according to your own needs and preferences. 
We closely monitor phase currents! Phase currents, often higher than battery currents, are frequently responsible for controller failures. Through precise measurement and analysis, we allow the controller to handle overloads repeatedly, but safely! The cut-off phase current is set to 1000A! The ESC remains cool even under heavy loads, thanks to its industrial design and efficient cooling system, including a fan.

What's new?

The X3-SERIES connects and retrieves data much faster than the previous generation. The new USBCOM6i PC module and CC_12 cables come with updated Controller 3 software (finally being available on MAC) with wireless connection and will soon support wireless connections and a mobile app.

The ESC can store multiple datalogs for up to 12.5 hours, eliminating the need to read and save data after each run. We've worked on reducing cogging during acceleration, achieving almost "sensored" performance while running sensorless motors. The ESC will automatically switch from sensored to sensorless mode if anything happens to your motor. (Battlebots team, we've got you covered).

Design change! 

By default, this controller is now shipped with ring terminals instead of soldered wires. This offers a stronger and industry-standard connection, allowing for easy replacement of wires with longer ones or the addition of external capacitors, all without the need for soldering.

The ESC comes with telemetry, a temperature sensor, and an ON/OFF switch.
