The new series GRAUPNER-BRUSHLESS. The HPD high-performace motors are characterized by a particularly high quality. The HPD motor series includes internal and external rotor motor types. The description of the motor gives details on its size, the speed per volt (KV) and the nominal voltage of the motor. The internal rotor motors of the GRAUPNER HPD series offer increased performance at high speed and are therefore primarily for racing boats or ducted fan powered models. The HPD 3860-2130 ist suitable for large racing boats, including power boats or similar models. In boat models, the inner rotor types are easily fitted with a water cooling
