Product function
1. Safe power-up function: when the power is on, no matter the throttle rocker is in any position, it will not start the motor immediately to avoid causing personal injury;
2. Throttle stroke adjustment function: adapt to the differences in throttle stroke of different remote controls, improve the linearity of throttle response, with smooth, delicate feel of the speed control and first-class speed control linearity;
3. Program setting items:
Battery type: Li-xx (Li-ion battery) / Ni-xx (Ni-Cd or Ni-MH), the default value is Li-xx (Li-ion battery).
Low Voltage Protection Threshold: Low/Medium/High, default value is Medium Cutoff Voltage.
When set to use Li-xx battery, it will automatically determine the number of Li-ion batteries, the cut-off voltage of each battery in low/medium/high case is 2.6V, 2.85V, 3.1V respectively. when set to use Ni-xx battery, the ESC will automatically detect the voltage of the battery pack when it is powered on, the cut-off voltage in low/medium/high case will be 0%, 45% and 60% of the input voltage at power on (0% means not to do low voltage protection).
When set to use Li-xx batteries, the number of Li-ion batteries will be judged automatically, and the cut-off voltage of each battery in low/medium/high case is 2.6V, 2.85V, 3.1V respectively.
When set to use Ni-xx batteries, the ESC automatically detects the voltage of the battery pack when it is powered on, and the cut-off voltage for low/medium/high cases is 0%, 45%, 60% of the input voltage at the time of power-on (0% means no low-voltage protection).
Start mode: normal/soft/ultra soft start, default value is normal start.
Normal start is suitable for fixed wing, it can start the motor quickly within 0.2 seconds.
Soft start/Ultra soft start is suitable for helicopter; the initial RPM of soft start and ultra soft start are relatively low, it takes 1 second and 2 seconds respectively from start to full speed; however, if you close the throttle after start, the motor will be started again in normal mode in 3 seconds, so as to avoid the airplane falling down due to the slow reaction when doing some aerobatic maneuvers.
Approach angle: low/medium/high, default value is medium approach angle.
Generally, low approach angle can fit more motors, but to improve efficiency, it is recommended to use low approach angle for 2-pole motors, and medium approach angle for motors above 6-pole. To increase RPM, the feed angle can be set to a high feed angle. After changing the feed angle setting, it should be tested on the ground before flying.
