Throttle calibration procedure

Important:
Please make the throttle calibration for the first time using ESC!

1. Turn on your transmitter and when fully initiated, move the throttle stick to the top position (ensure the throttle trim is neutral first).
2. Connect your flight battery to the ESC and wait for about 2 seconds.
3. The motor will make two short beeps, lower the throttle stick to the lowest position as soon as you hear these two beeps.
4. The motor will now beep a number of times (one beep for every cell in your flight battery) followed by a longer „Beep—–Beep“. This indicates that the throttle for your ESC is now calibrated and ready to use.

Normal startup procedure

1. Turn on the transmitter, and move the throttle stick to the bottom position.
2. Connect the battery pack to the ESC and wait for about 2 seconds.
3. The motor will beep several sounds, sound time presents the amount of battery cells.
4. When the motor emits ”Beep—-Beep”, which means the self-test is finished, and the ESC is ready to work.

Parameter setting and the way to check the ESC real-time data
The ESC parameters can be programmed to meet different flight needs. The ESC real-time data like current, voltage, ESC temperature, throttle, and ESC status code can be checked by LCD program card or Mobile phone APP. (LCD Programming Card and/or Bluetooth module needs to be purchased separately.)

2. Programmable parameter project description

1. Gov Mode:
   EXT-Gov/ESC StoGov, the default setting is ESC StoGov.

2. Low Voltage Cutoff Threshold
   2.7V/3.0V/3.2V/3.4V/3.6V/3.8V adjustable,default setting is 3.0V.
   (Note: the voltage means each cell voltage. For example, if you used a 6-cell Lipo battery, then the low voltage threshold value is 6x the set voltage value).

3. Timing
   Adjust the angle of the motor electrically. Auto/Low/Middle/High adjustable, the default setting is Auto.

4. BEC
   6.0V/7.4V /8.4V adjustable, default setting is 8.4V.

5. Motor Rotation
   CW/CCW is adjustable, the default setting is CW.

6. Governor Parameter P
   Control the degree of rotation while maintaining a fixed speed. The higher the value, the greater the degree of regression target speed when the speed is insufficient. Whereas, when the speed is too high, the function needs to be combined with the fixed speed sensitivity I setting. 1 to 10 adjustable, default setting is 4.

7. Governor Parameter I
   When the speed falls below, or exceeds the value set, the speed is compensated by the ESC. This parameter is used to resize the degree of rotation. Too large parameters will cause excessive make-up, and too small parameters will cause insufficient replacement.1 to 10 adjustable, the default setting is 3.

8. Acceleration
   The higher value means more soft throttle acceleration.

9. Auto Restart Time
   The ESC will cut off its output when the throttle amount is between 15%-30%, if you increase the throttle amount to above 30% within a preset time period (0-90s), the motor will rapidly start up and accelerate to the speed corresponds to the specific throttle amount, complete the shutdown and restart up. If you move the throttle stick to over 30% beyond the preset time period, the ESC will enter the soft start-up process.(Note: This function won‘t take effect if the throttle amount is less than 15%).

10. Helicopter Model
    When selecting the M4 / M4MAX corresponding models, there is no need to calibrate the speed controller for constant speed control. For other options, the speed controller needs to calibrate the speed for the first time when enabling constant speed control, the default setting is MAX.

The Fixed Speed Function Settings

1. Fixed speed description
   By speed calibration, the motor speed-throttle value corresponding curve is established. The throttle value is set to a fixed value on the remote control, the output of the throttle value corresponds to the speed, and the motor load changes to maintain the same speed.

2. Speed calibration process

3. Need to do the throttle calibration first before the speed calibration (if already done, just skip this step).

4. Make sure the main rotor pitch is at 0 degrees.

5. Pull the throttle stick to the minimum position, waiting for the esc self-check process.

6. Push the throttle to 50%, and the rotor of the helicopter will start to slowly accelerate (the main rotor pitch is zero degrees, the helicopter will not lift off,) and wait for the acceleration to complete, When the rotor speed is stable, push the throttle stick to the minimal position.

7. Speed calibration is finished.

8. If it is M4/M4MAX, calibration is not required, and you can directly choose the helicopter type. For other helicopters, you need to first select „Other“ and then proceed with calibration.

9. How to calculate the main rotor RPM at 100% throttle

10. Connect the LCD program card or Bluetooth after the speed calibration is completed to find the records as shown:
    The values in the figure are just an example, depending on the actual display values. This value is the maximum electrical speed that the motor can achieve at 100% throttle.

11. For example, if the motor has 10 poles, using 13 motor teeth with main teeth of 120T, the gear ratio is around 9.23. And Formula:
    100% throttle speed of the main rotor= MAX RPM/[(motor poles/2) x gear ratio]

12. Then the main rotor 100% throttle speed is 145000 / [(10/2) x (120/13)] is around 3410RPM.

13. If the main rotor during 3D flight requires to be maintained at 2500 rpm, the fixed speed throttle needs to be set at 2500/3410 to get about 0.8. At 0.8, the throttle value needs to be set at 80%.

14. You can set motor poles and the gear ratio (GR) on an LCD program card to get the speed of the main rotor at 100% throttle.

15. Connect the ESC to an LCD program card after the speed is calibrated, and then enter the interface as shown above.

16. Press “OK” to select options related to “motor poles”, press “OK” to select gear ratio (GR), then press “OK” will show the speed of the main rotor at 100% throttle.

Protection Function

1. Abnormal power-on voltage protection: The ESC enters a protective state once the input voltage detected is not in the operating voltage, Prompting the LED light to flash.
2. Start-up protection: If the motor fails to start normally within 2 seconds after pushing the throttle to start, the ESC will cut off the output power, and you need to make the throttle calibration again, the ESC can be restarted. Possible reasons: disconnection or poor connection between ESC and motor, the propeller or motor is blocked by other objects, the gearbox is damaged, etc.
3. Over-heat protection: When the temperature of the ESC is over about 110°C, the ESC will automatically reduce the output power for protection, but will not fully shut down the power, reduce it to 70% of the full power at most to ensure the motor has enough power to avoid crashes.
4. Throttle signal loss protection: The ESC will reduce the output power if the throttle signal is lost for 1 second, and will cut off output to the motor if the throttle signal is lost over 2 seconds. If the throttle signal is restored during power down, the ESC will immediately restore throttle control. In this way, the ESC will not protect when the signal loss is less than 2 seconds, only when the signal loss is over 2 seconds or longer time. And the ESC will reduce the output power gradually instead of cutting off it immediately, so the player has enough time to save the plane, taking into account safety and practicality.
5. Overload protection: The ESC will cut off power or restart automatically when the load increases a lot suddenly, the possible reason is the motor is blocked.
6. Low voltage protection: When the operating voltage of the ESC has exceeded the protection voltage set, power will be gradually reduced for safety, but will not be turned off, These will still be up to 50% of power, to ensure that the motor has the power to land.
7. Over-current protection: When the peak current exceeds the specified value, the ESC will immediately cut off the output power, and then restart to restore the power. If the current exceeds the specified value again, the output power will be completely cut off. A possible reason is overload, burnt motor and so on.
8. Break protection: If there is a break in the connection between the motor and ESC. Check the motor is fully connected, and check connectors or solder joints are as they should be.
