September '25 Updates! We have been working with a new factory that will be able to keep up with our demand, and at the same time we have switched to a larger M3 facemount screw and battleharden the gearbox by threadlocking every screw.
Looking to pair our Mega Spark Premium Planetary Gearbox with a different motor? Now you can! This is the gearhead for our Brushless Mega Spark Gearmotor, and includes a pinion to press onto a brushless or brushed drive motor of your choosing.
Features:
- 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.
- The huge 6mm diameter shaft is plenty strong for mounting drive wheels directly using 6mm Twist Hubs.
- Commonly paired with FT1806 brushless motors. (Ours have a custom shaft collar to prevent the motor shaft from snapping.) Choose 750KV for very large wheels or slow speed, 1500KV for most regular wheels, or 2300KV for small wheels (or ludicrous speed on regular-sized wheels!).
Specifications:
- Premium planetary gearbox with dual deep-groove ball bearings on the output shaft and metal gears in all stages
- Ratio: 27:1
- Length: 29.5mm + 38mm shaft (1.16in + 1.50in shaft)
- Diameter: 24mm (0.94in)
- Shaft: 6mm diameter, 38mm length, hardened steel with precision ground D-flat for setscrews or D-bore hub.
- Weight: 47.0g (1.66oz) (much of that is the extra long shaft, which we recommend cutting flush with the wheel if not needed)
- Face Screws: 4x M3-0.50 holes spaced equally on an 19mm circle, fits our Carbon Fibre Mega Spark Mount. M3x0.50 x 5mm Socket Head Screws are available here.
- Motor mounting: 4x 2mm holes spaced equally on an 16mm circle. Includes 4x M2x0.40 x 4mm Socket Head Screws.
- Includes 11T Pinion for pressing onto your motor. Bore is 2mm - make sure your shaft is too.
