ARMING ISSUE

一. Check if the status bar displays a hardware failure.

Observe the status bar; normal is indicated by blue, abnormalities are shown in red, and black signifies either not set up or a connection error, resulting in the peripherals not being recognized.

The GPS is not recognized as shown in the OSD.

The OSD indicates that the compass is not recognized.

二. Flight Controller Self-Check Items:

• Drone Attitude Issues: Ensure that the drone is placed flat on level ground before takeoff, avoiding inversion, vertical placement, or sideways positioning.

• In-flight Attitude Calibration: Ensure the compass is calibrated in the field with GPS lock, and after powering on, wait about 20 seconds without shaking the drone; the flight controller will calibrate the gyroscope automatically. Avoid shaking the drone during calibration to prevent failure. If abnormalities still display, repower the drone and leave it stationary following the above operations.

• CPU Load Issues: Consider that flight tasks or sensor data processing may cause CPU overload. Appropriately reduce additional functions to lighten the load.

三. Navigation Function Check:

• GPS Signal Issues：

  Ensure the GPS has a sufficient number of satellites locked, try repowering or move to an area with a clear view of the sky.

  Wait for the GPS to lock onto satellites.

  

• Arm Channel Conflict: Check if the arm channel is conflicting with other channels; the arm channel needs to be set independently.

• The picture below is an example of an error.

• Flight Mode Selection：Before taking off, make sure to select one of the flight modes such as auto-stabilize manual or semi-auto-stabilize. Avoid mistakenly choosing GPS-dependent flight modes like RTH (Return To Home), NAV ALTHOLD (Altitude Hold), etc., and ensure these are set on separate channels.

• Please separate the flight modes with navigation functions from the ordinary flight modes onto different channels.

  Do not mix the channels for GPS-enabled flight modes with those for normal flight modes, as this can easily lead to arming errors.

  The OSD will display the following prompts:

  

  Fail-Safe Settings: Set the fail-safe mode according to personal requirements. It is recommended to choose the return-to-home mode to ensure flight safety.

  Compass Calibration: If an error is displayed, please recalibrate the compass or check if the wiring is correct.

  Fail-Safe Settings: Configure the fail-safe mode according to personal needs. It is advisable to select the return-to-home mode to ensure the safety of the flight.

  Compass Calibration: If errors are displayed, please recalibrate the compass or verify that the connections are proper.

  

  The OSD displays as follows:

  

  Compass calibration requires a GPS lock with more than 8 satellites. Click the calibration switch in the image, then rotate the drone 360 degrees along each axis until the 30-second countdown ends.

  

  Accelerometer Calibration: If errors are displayed, please recalibrate the accelerometer.

  Ensure that the flight controller is removed and placed on a level surface during accelerometer calibration for greater precision.

  

  Verify Settings：If a non-original configurator is used, parameter settings may not be effective. Identify the incorrect parameters and change them to the original settings. If you cannot find the erroneous parameters, reset the flight controller and use the original configurator to readjust the parameters.

  Hardware Malfunction: As mentioned before, check the status bar.

  四.Check the Remote Controller settings:

  • Switch and Stick Position: Ensure that the switches and sticks on the remote controller are in their default positions.

  • Throttle Position: Make sure the throttle stick is at the lowest position, and verify that the romote controller's output values for the lowest and highest positions are between 1000-2000. If not, please recalibrate the romote controller's travel.

  When unable to arm, the OSD will also display corresponding prompts. Below are several other common items：

   ****

  Throttle not at the lowest position.

  

  Pitch stick not at center position.

  

  The transmitter's PWM output is incorrect; the correct values should be a minimum value ≤1000 and a maximum value ≥2000.

  

  By methodically troubleshooting these issues, you will be able to more accurately identify the cause of the arming problem and take appropriate measures to resolve them. If the issue persists, you may need to seek more professional technical support.
