This is a 4.5 Turn Reedy Sonic Modified Brushless Motor. After a three-year absence, the Reedy name is making a return to the competition 1:10 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, the 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.

Reedy Sonic Modified Brushless Motor (4.5T)
Definitely my favorite motors, the Reedy Sonic line are fast and efficient motors usable for any skill level. These motors produce tons of power, and have a very smooth bottom end. I recommend this wind of motor for touring car. I use these motors in all of my vehicles and wouldn't replace them.
