ProgrammableItems (The option written in bold font is the default setting)
1. Brake Setting： Enabled / Disabled
2. Battery Type： Lipo / NiMH
3. Low Voltage Protection Mode(Cut-Off Mode)： Soft Cut-Off (Gradually reduce the output power) /Cut-Off (Immediately stop the output power)
4. Low Voltage Protection Threshold(Cut-Off Threshold)： Low / Medium / High
1) For lithium battery, the battery cell number is calculated automatically. Low / medium / high cutoff voltage for each cell is: 2.85V/3.15V/3.3V. For example: For a 3S Lipo, when “Medium” cutoff threshold is set, the cut-off voltage will be: 3.15*3=9.45V
2) For NiMH battery, low / medium / high cutoff voltages are 0%/50%/65% 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 6 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%=4.32V。
5. Startup Mode：Normal /Soft /Super-Soft (300ms / 1.5s / 3s)
a) Normal mode is suitable for fixed-wing aircraft. Soft or Super-soft modes are suitable for helicopters. The initial acceleration of the Soft and Super-Soft modes are slower, it takes 1.5 second for Soft startup or 3 seconds for Super-Soft startup from initial throttle advance to full throttle. If the throttle is completely closed (throttle stick moved to bottom position) and opened again (throttle stick moved to top position) within 3 seconds after the first startup, the re-startup will be temporarily changed to normal mode to get rid of the chance of a crash caused by slow throttle response. This special design is suitable for aerobatic flight when quick throttle response is needed.
6. Timing： Low / Medium / High,( 3.75°/15°/26.25°)
Usually, low timing is suitable for most motors. To get higher speed, High timing value can be chosen.
