2 Features

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

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

2.3 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: 2.6V/2.85V/3.1V. For example: 3 Cell Li-Poly, when medium cutoff voltage is set, the cutoff voltage is: 2.85*3=8.55V.

2) For Ni-xx battery, low / medium / high cutoff voltages are 0/45%/60% of the startup voltage. (0% means the low voltage cutoff function is disabled). For example: 10 cells NiMH battery, fully charged voltage is 1.44*10=14.4V, when medium cutoff voltage is set, the cutoff voltage is : 14.4*45%=6.5V

? 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.

2.4 Full P rotection F eatures: Low-voltage cutoff protection / over-heat protection / throttle signal lost protection .

3 Advantages

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

3.2 Extreme low resistance, super current endurance.

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