Specifications 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.
