Repeat DRIVE MAX Brushless Gearmotor


Does your beetleweight suffer from a lack of drive power? Have you stripped the gearboxes on your drive motors leaving your bot stranded in the arena?
 Builder Peter Garnache suffered from these kinds of problems, and it inspired him to develop a new 24mm brushless gearmotor for your beetleweight bot.

We think these motors will make the combat robot world sit up and take notice.

The Repeat Max Drive brushless gearmotor is one of the most reliable new motors in the arena. It features a custom wound 2004 brushless motor coupled to a 24mm, 28:1 all metal planetary gearbox. These motors will empower you to drive circles around your competition… literally.

“Some have described the available torque [of brushless motors] as ‘apocalyptic'”

Beetleweights are rapidly becoming a common class of combat bots. Beetles are now better engineered and MUCH more destructive. While the available motors have been good, as the state of the art improves, the motors must improve as well. Imagine brushless power and control in your beetleweight! Now you can have it.

Repeat Robotics has taken the guesswork out of the brushless drive for the beetleweight class. With the matching ESCs, there’s no more fiddling with reflashing ESCs – just drop them in your robot and go!

Note: Brushless drive motors require a reversing ESC or your bot will not be able to drive backwards. Make sure you use the Repeat Robotics Reversing Brushless ESC or similar ESC with Reverse capability.


  • 2s-6s rated voltage
  • Custom wound 2004 brushless motor
  • 24mm, 28:1 all metal planetary gearbox
  • 6mm “D” extra long output shaft (cut to the length that you need to save weight)
  • Custom billet 4140 final planet carrier and output shaft
  • Output shaft c-clip has been changed to minimize the groove and provide the strongest product.

Important note:

Our first shipments from Repeat Robotics have arrived!

These will go quickly!

The new Repeat Max Drive Brushless Gearmotor is here. After dominating the antweight game with the Repeat Drive Mini Mk2 Brushless or the Repeat Drive Brushed, you can now dominate the beetleweight game. Want more speed and power? Want increased reliability? Look no further!

Repeat Drive Max Brushless Gearmotor Features:

  • Extended 38mm motor shaft: you can cut to length to improve versatility.
  • 34mm “D” groove for setscrew purchase.
  • Motor shaft is made from stronger steel (custom billet 4140 Alloy Steel) to survive larger impacts.
  • Output shaft c-clip has been changed to minimize the groove and provide the strongest product.
  • Custom billet 4140 alloy steel final planet carrier.
  • Custom wound 2100kv 2004 brushless motor.
  • Comes ready for combat, just solder the motor leads to a brushless ESC and you’re on your way (Soldering iron required)

Note: Brushless drive motors must be used with a reversing ESC or your bot can’t go backwards. Perfect for the job is Repeat Robotics Reversing Brushless ESC, designed specifically for the Mk2 motors.

These motors are designed to be used in combat, where anything can happen. The manufacturer is unable to accept returns for battle damaged products.

ItGresa Robotics is proud to support the builder community by offering and marketing their products. Repeat Robotics is run by a builder who is offering these motors to make the antweight scene in the US more competitive.
