The latest brushless motor technology along with the design and engineering experience that is responsible for 28 World Championship titles has been incorporated into their design. Even though these motors are designed with the hobbyist in mind, they are perfectly suited for track duty.
Due to its sensorless design, the Reedy 540-SL/550-SL Brushless Motor operates powerfully and efficiently without complicated sensor harnesses. The 540-SL features a 1/8" output shaft, making it perfect for use in 1:10 scale buggies and trucks, while the 550-SL features a high-torque 4-pole rotor and 5mm output shaft, which makes it an excellent choice for the increasingly popular short-course 4WD category.
A variety of models are available to suit most applications. Spare and option parts are also available.
