DJI - Propulsion System Error
There is something wrong within your propulsion system causing this error.
Diagnosing:
- Check the propellers for bends, cracks, or damage, and check whether the set screws are loose.
- Check whether the set screws of the motors are loose, whether the screws of the motor mounts are loose, and check whether the tilt angles of the motors are correct.
- Check if the locking handle and arm connector bolts are tight.
- Check the motors for any possible damages or imperfections.
- Check that your motor mount is stationary.
- If the motor mount is loose it is most common to see it because of a damaged arm.
Solutions:
- Restart Aircraft
- Tighten screws.
- Replace damaged prop
- Replace damaged motor.
- If the motor mount is loose, replace the arm.
- Downgrade and Reupdate if no damages are found.
- Replace corresponding ESC.
