I have been ridiculed because I tell people that they should Calibrate their compass (the DJI Dance) before every flight if they have moved flight locations by more than a .5 miles or less. I have also stated that before every flight, they should be sure and do an IMU calibration if possible, if not at least every 5 flights. I also suggest that a pilot remove all metal, watches and jewelry and even big belt buckles and get at least 25 yards from a car or truck before starting the motors. To stay away from concrete as most of it has metal inside it it is a big pad of concrete, it is call rebar and concrete wire, to keep concrete from splitting over time. Stay away from barbed wired fences and chain link fences as they will mess up a Phantoms compass big time. Remember, Metal Anything is bad to fly around or fly near, it is that simple men and ladies.
Last but not least, do yourself a favor next time you go flying and right after you take off. Just let the Phantom hover
at around 25 or 30 feet in the air, for a minute or two and watch the battery numbers. The Phantom should stay perfectly still and not move in any direction whatsoever. If it begins to drift in a calm wind situation, you would be advised to land and do all the calibrations. Remember, you can pull up the battery info at any time and something I think should now become S.O.P. for pilots at takeoff.
