Specifications Our first two shipments from Fingertech have arrived! These will go quickly! Once they are gone, leadtimes may be two months or more before we can get more back in. Buy now, so you are not disappointed! They’ve finally arrived! In development for nearly two years, the new Fingertech Brushless MegaSpark Gearmotors are here to step up your beetleweight game. (Yes we feel the irony of applying the naming convention “Mega Spark” to a brushless motor that generates no sparks!) Fingertech Brushless MegaSpark Gearmotor Features: Tuned for the perfect mix of speed and torque. Depending on wheel size, you can outrun or outpush any opponent! FingerTech’s signature extra long shaft can be used for added inboard/outboard bearing support, or for extra wide wheels! The huge 6mm diameter shaft is plenty strong for mounting drive wheels directly. If you need face-mounting screws, one pack of these will mount two motors: M2-0.40 x 5mm Flat Head Screws (8pcs) Mount to your robot using our Flat Mega Spark Mounts.

Fingertech Brushless MegaSpark Gearmotors: Tested by Experts! Near Chaos Robotics helped test these bad boys and we are proud to report that Team ItGresa got beat by a bot running these from Near Chaos. So we know they work!
