The VersaPlanetary Motor Coupler is designed to couple RS-775 or Falcon 500 Motors with the VersaPlanetary.
The coupler slides right through the VersaPlanetary’s motor mounting plate. No more split rings, and no more setscrews to tighten or worry about loosening. The 775 version is a press-fit for the the RS-775 motor. The Falcon Motor version slides on to the Falcon motor's shaft.
