1、Safety Power on Function: when power on, no matter where the throttle rocker is, the motor will not start immediately to avoid injury. 2、Throttle Stroke Calibration Function: The throttle stroke calibration function can adapt to the difference of throttle stroke of different remote controllers and improve the linearity of throttle response. 3、Delicate Speed Control: The RC electric speed controller has a fluent and delicate speed control feel and first class speed regulation linearity. 4、Low Voltage Protection Mode: With low voltage protection mode, when you reduce the power or turn off the output, the default is to reduce the power. 5、Good Anti Interference Ability: The power input terminal adopts the electrolytic capacitor with ultra low impedance and large capacity, which greatly improves the anti interference ability.
