The incredible performance of the SP5 is based on the stator, which is the heart of the motor. As with all REEDY Sonic motors, a high-quality sensor board is mounted inside the motor. The high-quality copper magnet wire is set to the maximum size permitted by regulations and the resistance value is set to the minimum value, and the wire treated with thermally conductive epoxy has self-heating properties to minimize the rise in internal temperature, which has succeeded in significantly reducing fade during racing.
