Single Speed, Double Reduction Gearbox

The same old two stage gearboxes teams have come to know and love. This is the latest and greatest update to the basic layout John V-Neun & Paul Copioli created for the original "Kit Transmission" included in the FRC kit of parts in 2005. After years of iteration, this gearbox has several subtle features which add to its superior performance.

Plastic Housings, Aluminum Shafts and Aluminum Gears provide for a light weight package. The specific transmission layout and ratio selections allow for an extremely small form factor, without a lot of complexity!

Weight: 1.26 lbs
Designed for use with 2 CIM Motors
Use the Optional Replacement Second Stage Gears to change ratios
AGMA 11 quality gears with teflon infused ceramic coating

Designed to work with Grayhill 63R series encoder (coupler required)
