    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!

    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.

    Overall Customer Rating of 2 Reviews:

    the spark 20:1 motors are some of the best gearmotors I have ever used. so far I have used them in 3 different antweight robots ranging from a lifter an overhead bar spinner to a full body spinner and now a drum spinner. I recomend cleaning them after every competetion or 30 minutes of use. this entails removing the gearhead and cleaning out the gears with denatured alcahol or a similar product and waiting until it is completly dry then relubricating with a high speed bushing oil for brushed motors as all gears ride on brass stages (the gears are steel not brass)

    The Spark motors are a great choice for drive motors in an antweight robots, but be sure to have the drive wheels protected. After the first gear in the gearbox, the shaft narrows down to approximately 1.5mm and tends to fail at that location with one or two direct hits to a wheel.
