Megaspark Brushless Drive Gearbox


We have long waited for Fingertech’s experience and reliability to be translated from antweight motors to beetleweight. Now, the long wait is over. After two years of development, Fingertech is proud to announce the FingerTech “Brushless Mega Spark” 24mm Premium Planetary Gearmotor.

We recognize that builders might want to use a different motor for your beetleweight. So we now offer the Fingertech Megaspark Gearbox by itself. You can mount it to ANY 1806 brushless motor with a 2mm shaft for the pinion.

“Some have described the available torque [of brushless motors] as ‘apocalyptic'”

Beetleweights are becoming more prevalent and more wicked. And the available motors have been good, but… imagine brushless power and control in your beetleweight! Now you can have it.

Fingertech, in their quest for the perfect combat bot that’s vicious to fight but easy to use, has taken the guesswork out of the brushless drive. No more fiddling with mismatched faceplates and reflashing ESCs – just drop them in your robot and go!

Included with each motor:

  • Premium 24mm Planetary Fingertech Megaspark Gearbox
  • (2) M2x4mm Mounting Screws
  • 11T Brass Pinion with 2mm bore

Fingertech Brushless MegaSpark Gearbox Features:

  • When mated with a 2300kv or 1500kv, this gearbox is 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! Use a rotary disc to cut off the excess.
  • Custom shaft collar to prevent the motor shaft from snapping.
  • The huge 6mm diameter shaft is plenty strong for mounting drive wheels directly.
  • Commonly paired with 1806 brushless motors. 1500KV for large wheels, 2300KV for small wheels (or ludicrous speed on large wheels).

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 Flat Mega Spark Mounts.
