Programmable parameters items and instructions

The options marked with “*” are the factory default setting.

Programmable parameters description

Govmode:

ESC Store Governor mode

Suitable for helicopters flying at a fixed headspeed. The throttle in this mode has to be more than 30% (including 30%) before starting the motor. The motor starts in an ultra-smooth manner. After the soft start, the governor will be activated, the factory default is ESC Store Governor mode.

Gyroscope Governor mode

Suitable for helicopters without any governor or helicopters using external governors. The throttle has to be higher than 5% (including 5%) before starting the motor. After the slow start is completed, the motor will start off with a smoother manner, followed by a faster throttle response accelerated to the current throttle value.

Fixed-wing mode

• Suitable for fixed-wing aircrafts. In this mode, the throttle has to be more than 5% (including 5%) to start the motor and the throttle response is rapid.

Low Voltage Cutoff Threshold:

• OFF/2.7V/3.0V/3.2V/3.4V/3.6V adjustable, the voltage means each cell voltage. For example if you use 6 cells Lipo battery, then the low voltage threshold value is 6 x set voltage value, default setting is 3.0V.

Timing:

• Adjust the ESC timing with the range of 0°-30°, the default setting is Auto.

BEC Voltage:

• The ESC is built-in with a BEC of 6-12V and has the capability to adjust 0.2V per step.

Motor Rotate:

This item is for setting the rotation direction of the motor, and it’s “CW” by default. After connecting the motor to the ESC, (if the motor rotates clockwise); when setting this item to “CCW”, the motor will rotate counterclockwise; (if the motor rotates counterclockwise), when setting this item to “CCW”, the motor will rotate clockwise.

GovParamP:

This parameter is for controlling the ESC to compensate the amount of the motor speed during the process of maintaining the speed-governing effect; the higher the value, the bigger the amount; and vice versa. This function needs to be combined with the Governor Parameter I.1-10 Adjustable, and the default setting is 4.

GovParaml:

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. 1-10 Adjustable, and the default setting is 3.

Acceleration:

• Fast/Normal/Slow/Very Slow adjustable, the default setting is Normal.

ARTime:

This feature is only available in ESC Store Governor mode. It is the time set to push the throttle from more than 30% to 25% to 30% throttle range, and then push back more than 30%. The parameter will not take effect when the throttle range is below 25% or between 25%-30% beyond the set time. The ESC will execute the ESC Store Governor mode of the default start-up process only if the throttle range is above 30%, the default setting is 90s ON.

Startup Power:

• Low/Middle/High adjustable, the default setting is Middle.

Brake Type

1. Normal Brake: When “Normal Brake” is turned on, after the throttle trigger return to zero position, it will make the motor stop running according to the parameter of brake force set, the default setting is Normal brake.
2. Reverse Brake: Plug the 3Pin signal wire into the throttle channel, and plug the RPM signal wire into any 2-stage switch channel of the receiver, then turn on the transmitter 2-stage switch.
   • The Reverse Brake function is turned on now, you can change the forward and reverse directions of the motor by flipping the 2-stage switch of the transmitter.

Warning

• This function can only be effective when the throttle is below 50%, and it is only allowed to be used when the airplane is landing on the ground, otherwise it may cause the ESC to burn!

Brake Force:

After throttle trigger is pulled to zero position, the higher value means the stronger brake force, and it will take shorter time to make the motor from running to standstill. 0%-100% adjustable, 1% as 1 step, the default setting is 0%. (This function only valid under normal brake mode.)

SR Function:

• The synchronous rectification function makes the ESC with higher driving efficiency and more energy-saving, and support longer flight time, the default setting is ON.

Cap Correction:

• When the battery consumption value recorded by the ESC is different with the actual battery consumption, the capacity adjustment can be applied to correct the discrepancy. This value ranges from -10% to 10%, the default setting is 0.

Pole Pairs:

• This value is necessary for calculating the actual RPM of the propeller, and it is usually indicated in the motor parameter table, the default setting is 1.

LED Colour:

• Red, green, blue, yellow, and white adjustable. It is used to display the ESC operation status and errors, the default setting is red.

Temp Fan:

When this function is turned on, the smart fan automatically detects the temperature after power-on, and automatically starts only when the temperature exceeds 40 degrees, but does not start below 40 degrees; when this function is turned off, the fan starts directly after power-on. The default setting is ON.

The Fixed Speed Function Settings

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.
• Note: The factory default setting is ESC store governor mode, you need to do the speed calibration for the first time, and the ESC will stores the motor speed throttle value corresponding curve after the speed calibration.
• If adjusting to any other mode from this mode and saving the “Motor RPM-Throttle” curve, and then adjusting back to this mode, the “Motor RPM-Throttle” curve saved by the ESC will be cleared, and you need to do the speed calibration once again.

Speed calibration process

1. Need to do the throttle calibration first before the speed calibration (if already done, just skip this step).
2. Make sure the main rotor pitch is at 0 degrees.
3. Pull the throttle stick to the minimum position, waiting for the esc self-check process.
4. Push the throttle to 50%, 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.
5. Speed calibration is finished.

How to calculate the main rotor RPM at 100% throttle

1. Connect Our APP after the speed calibration is completed to find the records as shown:

   • The values in the figure is just a example, depending on the actual display values.
   • This value is the maximum electrical speed that the motor can achieve at 100% throttle.

2. For example, if motor have 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) ÷ gear ratio
   • Then the main rotor 100% throttle speed is 151000 ÷ (10 ÷ 2) ÷ (120 ÷ 13) is around 3272RPM
   • If the main rotor during 3D flight requires to be maintained at 2500 rpm, the fixed speed throttle needs to be set at 2500 ÷ 3272 to get about 0.76. At 0.76, the throttle value needs to be set at 80%.

3. You can set motor poles and the gear ratio (GR) via our APP to get the speed of the main rotor at 100% throttle.

4. Connect the ESC to Our APP after the speed is calibrated, and then enter the intertace as shown above.

5. Select options related to “motor poles”, scrol screen select gear ratio (GR) by, then press “Save” will show the speed of the main rotor at 100% throttle.

6. Telemetry Instruction

7. When using Mikado VECT/E, Futaba SBUS.2, or Jeti transmitter, please connect the telemetry wire to the ESC’s RX port.

8. When using Rotorflight2, please connect the telemetry wire to the ESC’s TX port.

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 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, then 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 throttle signal is lost for 1 second, will cut off output to the motor if the throttle signal is lost over 2 seconds. If the throttle signal restored during power down, the ESC will immediately restored throttle control. In this way, the ESC will not protect when the signal loss less than 2 seconds, only when the signal lost 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 of time to save the plane, taking into account safety and practicality.
5. Over load protection: The ESC will cut off power or restart automatically when the load increased a lot suddenly, possible reason is the motor blocked.
6. Low voltage protection: When the operating voltage of the ESC have 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. 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,check connectors or solder joints are as they should be.
