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.
