Robot MarketPlace - FingerTech Silver Spark 33.3:1 Gearmotor

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

For strenuous conditions (such as robot combat), we recommend using Loctite on the screws that hold the gearbox to the motor. This will ensure they cannot separate during competition!

Features
Extra-long 3mm shaft for mounting wheels directly with the option to use a bearing support on the wheel's far side.
Same 11mm face mount pattern as Gold Spark motors.
All-metal spur gear reduction gearhead mated to a mabuchi FK-050 motor.
Several different gear ratios of 22.2:1, 50:1, 83.3:1, 100:1, 200:1, 300:1, and 600:1
At only 28grams (0.99oz), these are a lightweight and still powerful motor.

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!
