Hi guys turned controller on today on p4 red light and warning/beeping sound was going for bout 10 minutes what was that all about and what do lights on drone mean?
If the beeping and flashing red light start as soon as the remote controller is powered on, that's normally a sign that either the sticks were not in the center position when the remote controller was powered on or the remote controller needs to be calibrated.
If you can repeat that issue with the sticks in the center position, then try calibrating the remote controller in DJI GO like this:
