Every DJI product can warn you if it senses something is wrong with itself. The error messages that get my attention, not necessarily in order of importance, are
- ESC errors - this will actually make a drone fall from the sky
- Core board errors - can include overheating, loss of video, gimbal freakout issues
- Battery errors - anything having to do with battery over discharge or low battery warnings
- High wind conditions - your drone is telling you that it might not be able to fly based on the wind it detects
- Compass calibration error - if you take off and the compass goes out of calibration, you might never see your drone again
- Atti mode - while it's not an error message, its telling me that the navigation system is wonly. Use caution.
- Battery level only enough to RTH - gotta listen to this one or else youre going t be birddogging your drone
- Sport mode - not an error message, but if your sensors are off, your drone can let itself crash
- Gimbal motor overload - the gimbal isnt happy. Did you remember to remove your gimbal lock?
