Hello All, Quadcopter newbie here. I finally got time to get my new Phantom 4 out of the box today. I played with the flight simulator for a few minutes before going live. Went outside and put it in beginner mode and figured I'd practice take off and landings and small maneuvers until the battery ran down to get a feel for this thing. Anyway, on my very first landing as soon as it touches down I get this error message. Air Encoder Error (0xa). Any guidance to resolve this issue whatever it means?
