This is a 30A ESC, Multi-copter Brushless Motor Speed Controller with a running current of 30A. The power input uses extreme low output resistance greatly enhance the power stability, and has the protective effect on the battery. Separately voltage regulator IC for microprocessor. Providing good anti-jamming capability. Using Simon K’s a dedicated multi-copter program tgy_debug, and the master chip with high stability crystal oscillator, making the motor control to more precise.
