The Foil Drive v2 Motor Puck features a redesigned shape specifically for use with v2 motors and their detachable cable. When fitting the puck, the cable must first be connected to the motor, then the puck is fitted over the top of the cable, with the slot aligned with that of the motor cable. The supplied hardware (4x M4 16mm bolts) then secures the system in place. Note: The Motor Puck v2 is ONLY compatible with v2 motors from Gen2 systems. The Puck v2 uses slightly shorter mounting hardware than the original Puck v1s.
