This Gyre 350 motor has been modified and improved. Despite these modifications, this motor works perfectly well with the old XF300 controller, and of course with the new XF300CE controller.
As a result of the modifications made to this motor, the old Gyre XF350 cages can no longer be used. The new motor comes complete with new A + B cages.
The old cages are not compatible with this new motor. The old rotors, on the other hand, work with the new cages and motor.
All other Gyre 350 parts are fully functional with the new motor.
