This is the Reedy Sonic 4.0 Turn Short Course Sensored Brushless 550 Motor. 4WD Short Course is quickly becoming the one of the most popular competition classes in America. To satisfy the power demands that this class requires, Reedy developed the Sonic 550. Designed specifically for the Short Course 4WD class and intended strictly for competition, the Sonic 550 features 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.

Sensored operation results in a smooth and controllable power band with no cogging. A high-torque rotor is supported by dual ball bearings for maximum power output and reliability, while adjustable timing allows for fine tuning for particular applications and tracks. Service is easy and economical thanks to a completely rebuildable design.

  • Four ROAR-approved models to suit all tracks and conditions.

Reedy Sonic Short Course Sensored Brushless 550 Motor (4.0T)
I got this motor because my tekin pro 4 4600kv motor and rx8 esc blew up. I also purchased a LRP iX8 esc. With my losi ten scte running on 2s 6500mah 90c lipo pack, it ran about 175 degrees with a 10 tooth pinion (the air temp was about 95 degrees). It didnt seem it had the explosive rpm's that i wanted. I decided i wanted to put a 3s 5000mah 35c lipo into the car (because you can also run a 3s lipo to it). The car was an animal at that point. and i didnt even change the gearing. and things ran at around 160 degrees. I have to say, this is probably the best motor iv'e ever bought. I will buy even some of there 540 sized motors as well. reedy really did it right with the Reedy Sonic 550 4.0t Brushless Motor.
