1. Brake: ON/OFF
   ON – Sets the propeller to the brake position when the throttle stick is at the minimum position (recommended for folding props).
   OFF – Sets the propeller to freewheel when the throttle stick is at the minimum position.
2. Battery type: LiPo or NiCd/NiMH
3. Low voltage cutoff type: Reduce power/hard cutoff
   Reduce power – ESC reduces motor power when the preset Low voltage protection threshold value is reached.
   Hard cutoff – ESC instantly cuts motor power off when the preset low voltage protection threshold value is reached.
4. Low voltage protection threshold: Low/Medium/High
   For Li-xx packs – the battery cell number is calculated automatically. The Low/Middle/High cutoff voltage for each cell is: 2.85 V/3.15 V/3.3 V. For example: For a 3S LiPo, when the "Middle" cutoff threshold is set, the cut–off voltage will be: 3.15×3 = 9.45 V.
   For Ni–xx packs – 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-cell NiMH battery, the fully charged voltage is 1.44×6 = 8.64 V, when the "Middle" cutoff threshold is set, the cutoff voltage will be: 8.64×50 % = 4.32 V.
5. Soft acceleration start–up: Normal/Soft/Very soft
   Normal mode is suitable for fixed–wing aircraft. Soft or Very soft modes are suitable for helicopters. The initial acceleration of the Soft and Very soft modes is slower. It takes 1.5 seconds for the Soft startup or 3 seconds for the Very 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 set–up: Low/Middle/High
   Low (3.75°) – setting for most 2 pole motors.
   Middle (15°) - setting for motors with 6 or more poles.
   High (26.25°) - setting for motors with 12 or more poles, out runners.
   In most cases, middle or low timing works well for all types of motors. However, for high efficiency, we recommend the low timing setting for 2 pole motors (generally, in–runners) and middle timing for 6 poles and above (generally all outrunners). For higher speeds, high timing can be set. Some motors require different timing setups, therefore we suggest you follow the manufacturer-recommended setup.

Note: run your motor on the ground first after making any changes to your motor timing!
