1.Safe power on: When powered on, regardless of where is the position of throttle, motor will not start immediately, to avoid injury;
2 Throttle range calibrated: to adapt the throttle range of differences remote control, improving the linearity of throttle response; 
3 Programmable Items (available for throttle stick or LED parameter setting card settings): 

  • Brake setting: No brake /  brake;
  • Battery type: Lithium Battery / NiMH;
  • Low Voltage Protection Mode: Soft Shutdown / hard shutdown;
  • Low Voltage Protection Threshold: low / medium / high; 
  • Start Mode: Normal / Soft / Super-soft and starting; 
  • Timing: low / medium / high; 
  • Restore factory defaults;

4 comprehensive protection functions: 
undervoltage protection: the program is set by the user when the battery voltage is lower than the protection voltage, ESC automatically reduces the output power;

  • Overvoltage protection: if input voltage exceeds the input range, it will not be allowed to start, automatic protection, also issued rapid "beep beep" alarm sound;
  • Overheat protection: Built-in temperature detection, reduces the output power if the temperature is too high;
  • remote control signal loss protection: reduce power after the remote control lose signal for one second, two seconds the signal output is closed;
