Programmable Items :

1. Brake Setting : Enabled / Disabled, default is Disabled

2. Battery Type : Li-xx(Li-ion or Li-poly) / Ni-xx(NiMH or NiCd), default is Li-xx.

3. Low Voltage Protection Mode(Cut-Off Mode) : Soft Cut-Off (Gradually reduce the output power) or Cut-Off (Immediately stop the output power). Default is Soft Cut-Off.

4. Low Voltage Protection Threshold(Cut-Off Threshold) : Low / Medium / High, default is Medium.

1) For lithium batteries, the number of battery cells is calculated automatically. Low / medium / high cutoff voltage for each cell is: 2.6V/2.85V/3.1V. For example: For a 3 cells lithium pack, when ¡°Medium¡± cutoff threshold is set, the cut-off voltage will be: 2.85x3=8.55V.

2) For nickel batteries, low / medium / high cutoff voltages are 0%/45%/60% of the startup voltage (i.e. the initial voltage of battery pack), and 0% means the low voltage cut-off function is disabled. For example: For a 10 cells NiMH battery, fully charged voltage is 1.44*6=8.64V, when ¡°Medium¡± cut-off threshold is set, the cut-off voltage will be:8.64*50%=4.3V

5. Startup Mode : Normal /Soft /Super-Soft, default is Normal.

Normal is preferred for fixed-wing aircraft. Soft or Super-soft are preferred for helicopters. The initial acceleration of the Soft and Super-Soft modes are slower in comparison, usually taking 1 second for Soft startup or 2 seconds for Super-Soft startup from initial throttle advance to full throttle. If the throttle is closed (throttle stick moved to bottom) and opened again (throttle stick moved to top) within 3 seconds of the initial startup, the restart-up will be temporarily changed to normal mode to get rid of the chances of a crash caused by slow throttle response. This special design is very suitable for aerobatic flight when quick throttle response is needed.

6. Timing : Low / Medium / High, default is Low.

Usually, low timing value can be used for most motors. We recommend the Low timing value for 2 poles motor and Medium timing value for motors with more than 6 poles to get a high efficiency. For higher speed, High timing value can be chosen.
