undervoltage protection (Cut-Off Mode): Soft Cut-Off (Gradual reduction of power) / Cut-Off (Immediate standstill) 

4.

 

cut-off voltage for undervoltage protection (cut-off threshold): low / 

medium 

/ high 

1)

 

For lithium batteries, the number of cells is calculated automatically. 

Low / Medium / High cut-off voltage for each cell is: 2.85V/3.15V/3.3V. 

For example: For a 3S LiPo, with "Medium" switch-off setting, the switch-off voltage is 3.15V x 3 = 9.45V. 

 

2)

 

For NiMH batteries the cut-off voltage is: low 0% / medium 50% / high 65% of the output voltage 

(e.g. the nominal voltage of the battery pack) and 0% corresponds to the deactivated 

undervoltage protection. 

For example: For a 6 cell NiMH battery the voltage after charging is 1.44V x 6 = 8.64V, for "medium" 

setting the cut-off voltage is 8.64V x 50% = 4.32V. 

5.

 

Start mode: 

Normal

 /Soft /Super-Soft (300ms / 1.5s / 3s) 

Normal mode is suitable for any aircraft. Soft or Super-Soft Mode is suitable for helicopters. 

The first start in soft and super soft mode is slower, it takes 1.5 seconds for soft start or 3 seconds for super soft start from first start to full throttle. When the throttle is fully 

released (throttle lever in lowest position) and is operated again within 3 seconds (throttle lever in full throttle position), the repeated throttle shock is performed 

temporarily in normal mode to avoid the possibility of a crash due to too slow a throttle reaction. 

This special function is especially useful for aerobatics, where fast throttle reactions are necessary. 

6.

 

Timing: 

Low 

3.75°/ Medium 15°/ High 26.25° 

Normally a low setting is suitable for most engines. For more speed a higher timing setting can be selected.
