The Silver Spark Motor 11:1 motor makes it super simple to get a robot moving! Just pick up a pair of Snap Wheels and Snap 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.
Note – For strenuous conditions (such as robot combat), we recommend removing the gearbox and ensuring that the motor vent hole does not line up with a gearbox pin. If it does, simply rotate the gearbox 180 degrees and reattach. Use Loctite on the screws that hold the gearbox to the motor. This will ensure they cannot separate during competition!
