1.7 Packaging include:

     3 sets of gold plated motor connectors and heat-shrink tubings (Remark: motor connectors and heat-shrink tubings need to be purchased additionally)

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 Settingsbrake enabled / brake disabled, default is brake disabled

Battery TypeLi-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 Cells 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  protection function is disabled) . For example: a 10 cells NiMH battery pack, 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 Protection Features: Low-voltage cutoff protection / over-heat protection / throttle signal lost protection.

3   Advantages

3.1 Military Standard 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.
