REEDY SONIC 540 M3 BRUSHLESS MOTOR SS 21.5T 1S SPEC

A competition-proven short stack stator, wound with pure copper magnet wire and low-resistance collector rings, walks the edge of legality in exchange for maximum power output and RPM. Despite being designed for 1S applications, short stack motors can, under the right circumstances, create a power advantage in 2S applications such as F1 and 4WD GT classes.

Like all 540-M3 motors, these new models feature a three-piece, CNC-machined can to reduce weight while improving airflow, component fit, and bearing alignment. Heavy-duty silver-plated solder tabs reduce resistance, feature a cupped profile to aid soldering, and are well supported to prevent internal connections from fatiguing over time.

A balanced, high-strength sintered rotor provides powerful, fade-free performance thanks to improved manufacturing processes. To fine-tune for specific applications and tracks, a variety of optional rotors are available. Lastly, larger precision stainless steel ball bearings have been fitted to accommodate high RPM loads with improved reliability.

Both models meet ROAR, EFRA, and IFMAR specifications.
