Disclaimers

Thank you for purchasing this product! The brushless power system has strong power, and incorrect use may cause personal injury and equipment damage. Therefore, we strongly recommend that you carefully read this manual before using the equipment and strictly follow the prescribed operating procedures. Our company does not assume any responsibility arising from the use of this product or unauthorized modification of the product, including but not limited to compensation for incidental or indirect losses.

Note:

1. Please strictly follow the parameters in the table when using, otherwise it will cause permanent damage to the product.

2. Do not use DC power supply when testing the ESC. DC power supply may have surge voltage, and when the ESC activates the active braking function, the DC source will superimpose the motor back electromotive force on the ESC, causing it to burn out.

Utility Wizards 

Throttle stroke calibration and electronic tuning parameter setting

*After using this product for the first time or replacing the remote control device, throttle stroke calibration is required

*When there is an abnormality in the electrically controlled drive disc motor or when a higher speed is required, it is possible to try changing the feed angle parameters;

*The default parameters for ESC at the factory are high pitch angle, active braking, and medium acceleration;

Adjustment steps and precautions

1. Connect the ESC signal line to the receiver, power on the receiver, and match the frequency with the remote control

2. Power off the ESC, press the throttle lever upwards, turn on the ESC, and enter the remote control parameter adjustment mode

3. Use the sound generated by the motor to identify which tuning mode is currently in. If you need to adjust the current parameters, simply move the throttle lever downwards to complete the tuning. Then, the electric tuning will exit the tuning mode and enter the working mode.

4. Only one parameter can be adjusted at a time. If it is difficult to distinguish which parameter is currently setting the sound, power off and then power on the ESC, repeat step 1.

5. In the "Reset All Parameters" mode, pressing the accelerator down will restore all parameters to their default settings.

Protection Function Description

This ESC is designed specifically for multi rotor aircraft.

Start protection: If the motor fails to start normally within two seconds after increasing the throttle, the power output will be turned off by the ESC, and the throttle lever must be placed at the lowest point again before restarting. (The reasons for this situation may include poor contact between the electric harmonic and motor connections or individual output lines being disconnected, or the propeller being obstructed by other objects.).

Throttle signal loss protection: When the electronic control detects that the throttle remote control signal is lost for more than 0.25 seconds, the output will be immediately turned off to avoid greater losses caused by the continued high-speed rotation of the propeller. After the signal is restored, the ESC immediately resumes the corresponding power output.

Lockup protection: When the electric control detects motor stalling, it will attempt to restart the motor 3 times. If the restart is unsuccessful, the electric control will completely shut down the output and no longer attempt to restart the motor. At this time, the throttle lever needs to be set to the lowest position and pushed again to clear the error and restart the electric control to restore power output.

Current protection: When the instantaneous abnormal current reaches 340A, the electric regulator immediately shuts off the output, and can restore normal operation after re powering on.
