Factors first - wind was heavy - maybe 18mph. Sunny day, mix of city, water, traffic. Had one great flight at New Smyrna, Fl. Moved drone to a spot under a tall bridge (still had great GPS) and put in the second battery (DJI Battery). Then, problems. Home point spontaneously resets itself to over the water While over the water, I lost GPS and go to P-OPTI Noticing that it is drifting (remember the wind?) heavily, I circle back, and it goes to P-ATTI Flight now is really wild in the wind, so bringing back and I get 'Motor Obstruction' error. White knuckle, but safe landing. Photos show progression of all except motor obstruction (at the end). Any thoughts? Scared stuff!
