Reedy Sonic 540-M4 Sensored Brushless Motor, 4.5 Turn...
Reedy Sonic 540-M4 Sensored Brushless Motor, 4.5 Turn

Internally, the 540-M4 is very similar to that of the 540-M3 that it replaces - it produces the very same linear powerband and excellent mid-range feel that have actually become synonymous with Reedy's modified motors. Nevertheless, modifications can be excellent when they serve a function. In the case of the 540-M4, the inner bearing has been moved so that it belongs to the can rather of the sensor assembly, which more specifically lines up the rotor within the magnetic field while decreasing sound and vibration.

Externally, the motor has 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 powerful fade-free efficiency. A variety of optional rotors are offered to fine-tune for specific applications and tracks. Precision stainless-steel ball bearings have actually been fitted to reliably accommodate high RPM loads.
