Brushless motor controller to where?

Brushless motor controller mainly good? Why so many people choose. Below small make up take you to understand it. 1. Compared with a brush motor controller, no brush, brushless motor controller, therefore, no electric spark generated when running, reducing the electric spark interference of remote radio equipment. 2. Because there is no brush, runtime frictional resistance decreases, and make the running more smoothly, lower noise. 3. Because they had no brush, brushless motor controller of wear are mainly concentrated on the bearing, so from a mechanical point of view, it is almost a maintenance-free motor, only need to do some cleaning maintenance. Above all, do you know where the good brushless motor controller.
