This is the Express Motorsports "Zapper" D3.5 17.5 Turn Brushless Motor. This D3.5 based, Zapper series motor is 100% designed for spec racing! The "Zapper" motors have been tweaked to extract every bit of power from the EPIC D3.5 line. This includes checking the strength of the rotor and the inductance of the stator, and then matching the best rotors with the best stators. They are also checked for any defects, proper bearing alignment and shimming. This provides you with a reliable blueprinted motor that has all the same tweaks as the motors driven by Express team drivers, ensuring the motor you receive makes optimum power. Sensor wire included.
