FingerTech "Silver Spark" 16mm Gearmotor 50:1

Silver Sparks are the go to motor for Antweight robots.   Extra-long 3mm shaft for mounting wheels directly with the option to use a bearing block for support on the wheel's far side. 11mm face mount pattern. All-metal spur gearhead mated to a Mabuchi FK-050 motor. 8 different gear ratios for a wide range of rpm and torque to choose from. Weights from 28 - 32grams (0.99 - 1.13oz). (see details) These motors make it super simple to get a robot moving! Just pick up a pair of Foam Wheels and Twist 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 Flat Motor Mounts for when you want to face-mount in a panel.Note - For strenuous conditions (such as robot combat), we recommend removing the gearbox and checking 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 mo
