The MAXPlanetary Base Kit is the entry point into using the MAXPlanetary System. This base kit includes a universal input stage, 1/2in hex socket output, hardware pack, 8mm keyed input coupler kit, and a 1/2in rounded hex shaft. Purchase a MAXPlanetary 3:1 Cartridge (REV-21-2101), MAXPlanetary 4:1 Cartridge (REV-21-2102), or MAXPlanetary 5:1 Cartridge (REV-21-2103) to complete your system. Add a NEO Brushless Motor (REV-21-1650) or an adapter kit if you want to use a different motor, like the new MAXPlanetary Falcon Spline Input Coupler (REV-21-2124) or MAXPlanetary Kraken X60 Compatible Input Coupler (REV-21-2138).

The MAXPlanetary System is a cartridge-based modular planetary gearbox designed from the ground up for NEO-class motors. The design of the MAXPlanetary has been carefully optimized to provide torque density unavailable in FRC up until now.

Notes

As of 11/14/2022, MAXPlanetary Base Kits (REV-25-2109) will ship with an updated MAXPlanetary 8mm Keyed Input Coupler Kit (REV-25-2108). The input coupler kit was adjusted to be slightly shorter so that the CIM, Mini CIM, and Falcon no longer require the shim plate. As a result, the MAXPlanetary CIM/Falcon Spacer (REV-21-2119) is no longer included in the MAXPlanetary Base Kit.
