You demand the best, so does Rotor Ron! This is one of the best 21.5 motors I offer.
This motor is professionally built and tuned to Rotor Ron’s strict parameters. What does that mean you ask? First, I upgrade the stock bearings to ceramic bearings lubed with SHAG Oil to allow the motor to spin more freely. It includes the rotor properly shimmed, complete evaluation of stator poles, rotor strength & asymmetry and sensor board deviation. This motor has an aligned sensor board that is within my personal strict standards. Bottom line, you will get an awesome motor!
Includes Rotor Ron Dyno Service and instructions that will get you up to speed, fast! (A $34.99 Value!) No need to ever touch the timing again! Motor specs and dyno sheet included along with stickers for your vehicle.
The X-Factor spec class brushless motor has a revolutionary timing ring and a locking end plate systems. Only 6 short screws (no long screws) to make it lighter. X-Flow Cooling which pulls more air through the can, reducing motor temperatures. Also made with CNC Machined Aluminum to allow for more accurate alignment.
