These are what your robots have been waiting for. Our custom engineered robot drive motors are designed to handle the rigor of combat without breaking, and they won't hurt your wallet either!

• The extra-long 3mm shaft is triple-supported internally so that wheels can be mounted directly.
• Having the same face mount pattern as the now-obsolete BaneBots 16mm gearmotors means they can be a direct drop-in replacement for all your combat-worn BaneBots motors.
• Spur gear reduction motor with mabuchi FK-050 motor.
• 9 different gear ratios of 20, 35, 50, 63, 86, 115, 150, 250, and 360:1
• At only 28grams (0.99oz), these are a lightweight and still powerful motor.

These motors make is super simple to get a robot moving! Just pick up a pair of Lite Flite wheels and Lite Hubs to mount them, solder on a pair of tinyESCs and your motors are ready to be driven by radio control!  For mounting the motors, use these 2-56 screws.  We now also carry 3mm bearings for supporting the shaft in heavy robots or weapon systems.

No Load Speed @ Gear Ratio/Voltage (Click to Enlarge) Motors have been tested to work up to 22.2V (6 lipoly cells), but don't expect the motor to run that high forever!

Maximum Torque @ Gear Ratio/Voltage (kg-cm) (oz-in) (Click to Enlarge) Exceeding 6.84kg-cm (95oz-in) will damage the output gear stage. Do not stall the motors highlighted in red at the indicated voltage.

July 8: If the gear ratio you want is out of stock, try our US distributor The Robot MarketPlace.  Motors are on order (but delayed of course) and should be here by mid August.
