2. Programmable adjustments:

1. Brake: enabled / Disabled

2. Battery type: Lipo / NiMH

3. 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.
