I purchased an inspire 1 last May. The drone flew wonderfully. One day it was up in the air and was flying around in a circle. Yes I did all of my pre flight tests and worked out perfectly. I was able to gain control but the drone decided to fly in ATTI mode all by itself. My question for anyone is I am thinking about purchasing a new Inspire 1 but a little nervous that this will happen again. What can I do differently? Do fly aways happen frequently? Is there a way that I can choose Atti mode in the flight simulator so I can get practice on this?
