Feature: 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. Higher Accuracy: 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. Linear Adjustment: Smooth and stable speed control feel and speed regulation linearity, which also ensures higher working stability. 4. Low Voltage Protection: Reduce power or turn off output, and the default is to reduce power, effectively protecting the RC model. 5. The Input Terminal: The power input terminal adopts the electrolytic capacitor with ultra low impedance and large capacity, which greatly improves the anti interference ability.
