Robot MarketPlace - FingerTech Spark 250:1 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!

Features
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.
Several different gear ratios of 20:1, 35:1, 50:1, 63:1, 86:1, 115:1, 150:1, 250:1 and 360:1
