l Drive tube and high-power Mos, and Mos tube plus a separate heat sink, Extreme low output resistance of the PCB(printed circuit board),super current endurance. 2 The power input uses extreme low output resistance greatly enhance the power stability, and has the protective effect on the battery. 3 Safety electrical function: when the power is turned on, regardless of the throttle stick in any position does not start the motor immediately, to avoid personal injury. 4 Separately voltage regulator IC for microprocessor. providing good anti-jamming capability. 5 Supported motor speed (Maximum): 210000 RPM (2 poles), 70000 RPM (6 poles), 35000 RPM (12 poles). 6 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.
