Does your antweight suffer from a lack of drive power? Have you stripped the gearboxes on your drive motors leaving your bot stranded in the arena? I too have suffered from these problems. That's why I started developing the first off-the-shelf 16mm brushless gearmotors to be sold to combat robot builders. Repeat drive mini Mk3 is the upgraded version of my game-changing brushless gearmotors, featuring a custom wound 1204 brushless motor coupled to a two stage, 28.5:1, all metal, 16mm planetary gearbox. These motors will empower you to drive circles around your competition... literally.

The wires on these motors can break if tugged directly. Adding a bit of hot glue near the entrance helps. Do not handle the motors by the wires and take care when stripping the wires.

Improvements:

  • 1104 was changed to a 1204 brushless motor for more power
  • Increased kv to 3500 and increased gear ratio to 28.5:1 to keep speed consistent but increase power
  • Motor shaft was extended so you can cut to length to improve versatility
  • Output shaft is made from hardened 4130 steel, to improve lifetime and is integrated into the carrier plate, to improve durability.
  • Output shaft is retained without the use of a circlip, eliminating the main failure mode and improving the durability
  • Improved motor wire gauge and attachment method to make it more durable than ever.
  • Gearbox baseplate is integrated into the brushless motor base, removing screws and additional points of failure.
 

Features:

  • 1204 3500kv custom brushless motor
  • 2s-4s rated voltage
  • 16mm, 28.5:1 all metal planetary gearbox
  • 4mm "D" extra large extra long output shaft (can be cut to length)
  • ~24g weight (can lower the weight by cutting down the shaft and shortening the wires)
  • 10.5mm M2 Face mount hole pattern
  • Comes with Repeat Inside sticker sheet (one per order while supplies last)
  • Comes ready for combat, just solder the motor leads to a brushless ESC and you're on your way (Soldering iron required)
 

Speed

~909 rpm @ 2S (7.4V) ~1363 rpm @ 3S (11.1V) ~1817 rpm @ 4S (14.8V)
 
Disclaimers: The wires on these motors can break if tugged directly. Adding a bit of hot glue near the entrance helps. Do not handle the motors by the wires and take care when stripping the wires. 
These gearboxes can only accept ~2mm of face screw engagement. Using screws that are too long will result in damage.
These motors are being used in combat, where anything might happen. I am unable to accept returns for battle damaged products.
