I have had problems in the flight of a fixed wing with compass and external gps and AP Pixhawk,. During the mission in Auto the drone suddenly begins to fly in an uncontrolled way I am assuming that it is a “toiletbowling”. This is new, I had done many flying missions and had no problems. I made a change from GPS + Compass from 3Drobotic to a more modern GPS + Compass and changed its position, more removed from interference and made a magnetic declination adjustment. Fortunately the drone has recovered and enters RTH
