CALIBRATE ESC 

Step1: switch to manual mode. 

Step2: unplug the ESC signal line and wait for ESC to make a di---di---di--- sound. 

Step3: move the throttle stick to the max position, then plug in the ESC signal line. 

Stpe4: hear di—di—, then move the throttle stick to the lowest to complete the calibration.

PRE FLIGHT CHECKLIST                                                                                                                                           

Check the rudder feedback is correct 

Check the firmware version to keep the firmware up to date 

Check if the FC attitude line is level. If it is not calibrated for a long time or the temperature changes too much, you 

need to recalibrate. 

Check if the battery voltage 

Confirm the position of each mode 

Confirm that the Home location has been updated. 

Confirm the vibration of the body and open the acceleration curve display. If the vibration is too large, the attitude will 

be disordered. It is recommended to keep the vibration amplitude within the warning line while maintaining horizontal 

flight. 

* Recalibration level is also required after changing the direction of FC installation 

* If you do not calibrate for a long time, or if the temperature changes too much, you need to recalibrate level (even if the attitude line looks level)

The vibration is in good condition. When the plane is flying flat, the vibration point is scattered within the two warning lines. 

 

 

The vibration is large, and most of the vibration points fall outside the warning line, which easily leads to the FC 

can’t calculate the correct attitude 

 

 

 

Calibrate Level 

Ensure that the aircraft is level and stationary during horizontal calibration. 

 

Horizontal calibration is required after changing the mounting direction.
