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.
• All-metal spur gear reduction gearhead mated to a 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 yet powerful motor.

These motors make it 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 2-56 screws and our custom motor mounts.  We now also carry 3mm bearing blocks for supporting the shaft in heavy robots or weapon systems.

Our friends at KITBOTS have made a flange face mount for Gold Spark and Silver Spark motors.

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 @ 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.
