It now comes with a 2.5mm Aluminum Shorting ring (demodulation ring) to help reduce inductance in the motor. This can help with power compression. It also acts as an internal heatsink by pulling heat from the windings into the aluminum ring and direct to coil venting cycles air across the coil windings and aluminum shorting ring at the same time cooling them simultaneously.
