COMPACT 300 7.4V motor set

GRAUPNER COMPACT motors are brushless external rotor motors. All of the motors in this series impress with huge torque and demonstrate their full potential for power and performance in direct drive.
The design principle behind the COMPACT motors succeeds in combining a compact motor housing with optimum power to weight ratio.
Motors with the addition of a "Z" in their designation are equipped with an extensive range of accessories as standard. (See fade-in photo.) Other types of motor are supplied with compatible retaining screws.
