Scary moments yesterday afternoon: after flying in P-GPS mode with 19 satellites present, I suddenly saw a message: "Compass error, exiting P-GPS mode" after which it switched to ATTI mode by itself; the controller still being in P-mode. What followed is funnily enough not recorded bij the DJI GO app: the Inspire Pro took a glide path down as if it had wings and crashed in a field. Nothing I did on the controller helped. As I got to the bird the controller said: "maximum altitude reached". Visual damage: dislocated arms, broken screw of the landing gear, broken shock absorber. Because it was a training session I was flying without the X5. I fly with the latest version of everything. Bird is still within warranty. Any ideas, same experiences? Tips? Tnx!
