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.
For the last 12 months, the Reedy development team has been working behind the scenes utilizing a combination of new ideas and proven concepts to create the all-new Sonic 540-M3 Competition Brushless Motor.
On the outside, the 540-M3 appears very similar to the Mach 2, but look closely and you will realize that nothing has been carried over from the previous model. A 3-piece CNC machined can reduces weight while improving airflow, component fit, and bearing alignment. Heavy-duty silver-plated solder tabs are not only thicker to reduce resistance, but are also cupped to aid soldering and well supported to prevent internal connections from fatiguing over time.
