Safety Arming Feature: Regardless the Throttle Stick position, the motor will not spin after battery connected. This will prevent any injury happened.

Throttle Calibration: Throttle range can be configured to provide best throttling linearity, fully compatible with all market available transmitters.

Programmable Items:

●Brake Settings:brake enabled / brake disabled, default is brake disabled

●Battery Type:Li-xx(Li-ion or Li-poly) / Ni-xx(NiMh or Nicd),default is Li-xx.

●Low Voltage Protection Mode(Cutoff Mode) :power reducing / power cutoff, default is power reducing.

●Low Voltage Protection Threshold(Cutoff Threshold) :low / medium / high, default is medium cutoff voltage.

1) For Li-xx battery,number of battery cells are judged automatically,low / medium / high cutoff voltage for each cell are: 2.5V/2.75V/3.0V. For example: 3 Cell Li-Poly, when medium cutoff voltage is set, the cutoff voltage is: 2.75*3=8.25V.

2) For Ni-xx battery, low / medium / high cutoff voltages are 60%/65%/70% of the startup voltage. For example: 6 cell NiMH battery, fully charged voltage is 1.44*6=8.64V, when low cutoff voltage is set, the cutoff voltage is : 8.64*60%=5.2V。

●Startup mode: normal / soft / super-soft, default is normal startup.

●Timing: low / medium / high, default is medium timing.

In normal cases, low timing can be used for most motors. But for high efficiency, we recommend the Low timing for 2 poles motor and Medium timing for 6 poles and above. For higher speed, High timing could be used.

Full Protection Features: Low-voltage cutoff protection / over-heat protection / throttle signal lost protection.


Military Standard Capacitor with extremely low resistance used on voltage input section, this will increase the prevention of unwanted RF Noise/ Interference during flying.

Dual PCBs: Control circuit and MOSFET circuit use separate PCB, adiabatic air gap between 2 PCBs reduces the heat exchange form MOSFET to control circuit, so the ESC works more reliable.

Extreme low resistance, super current endurance.

Microprocessor and BEC use separate voltage regulator IC, with good anti-jamming capability.
