Reedy Sonic 540-M4 Sensored Brushless Motor, 4.0 Turn...
Reedy Sonic 540-M4 Sensored Brushless Motor, 4.0 Turn

Internally, the 540-M4 is very similar to that of the 540-M3 that it changes - it produces the exact same linear powerband and excellent mid-range feel that have become synonymous with Reedy's customized motors. Nevertheless, modifications can be great when they serve a purpose. When it comes to the 540-M4, the inner bearing has actually been moved so that it belongs to the can instead of the sensor assembly, which more exactly lines up the rotor within the electromagnetic field while lowering noise and vibration.

Externally, the motor has actually been reduced, which results in more centralized weight circulation within the chassis. The reduced length, combined with improvements to the can develop, results in a 5-10g decrease in weight.

A well balanced, high-strength rotor offers effective fade-free performance. A variety of optional rotors are readily available to tweak for particular applications and tracks. Precision stainless steel ball bearings have been fitted to reliably accommodate high RPM loads.
