Overview:

After a three-year absence, the Reedy name has returned to the competition electric motor scene. Reedy`s Sonic line of brushed motors were a favorite of racers worldwide and powered numerous National and World Champions in the late `80s and early `90s. It is only fitting that the famous Sonic name be revived for the first complete line of competition brushless motors from the world-renowned Reedy brand. 

Designed strictly for competition and already proven at the highest level, Reedy Sonic brushless motors feature a lightweight case design with extra-large, strategically placed vent holes to reduce operating temperatures. Lower temperatures result in less fade over the course of a race, longer run times, and increased motor life. 

A precision balanced high-strength sintered rotor is supported by dual ball bearings for maximum RPM and reliability. Adjustable timing and a variety of optional rotors allows for fine tuning for particular applications and tracks. 

Several models for both stock and modified racing are available and all meet ROAR, EFRA, and IFMAR specifications.
