I recently had a very violent crash and my P2 is un usable at the point. I have had some practice in ATTI mode but for the most part I utilized the GPS function to keep the unit stablized, like most. when I had fiddled arround with the ATTI mode it hovered well, but was susceptible to wind and motor balancing. still though, I couldnt get it to pitch or roll to a point that I couldnt recover from, about 30 degrees.
which leads me to wonder what exactly happened in my most recent outing. from the ground, what i experienced was 7-8 sat connections running perfectly fine in GPS mode for about 6 minutes of flight, then all of a sudden it started turning to the right and rolling to the left even though thats not what my controls were doing at that point. I assumed I lost a connection with 2 sats but was too busy watching the aircraft to see my screen. When I tried to correct it started pitching forwards and rolling to the opposite side but wouldnt go back. the unit went over perpendicular to the ground about 100-110 degrees from level and drove itself into the ground at ~mach 2. unfortunately it was pitching towards me at that point and I have no LED refence for if the compass got messed up mid flight or GPS loss or anything. I have a video of the event and the go pro on the H3 is at about 45-50 degrees from the horizon, on a maxed out gimbal. The one prop is clearly visible going over vertical.
contoller had been calibrated the night before and the unit itself had the compass calibrated before the flight and I did not take off untill a home point was recorded.
is this normal? I havent spent enough time not using GPS to know its limits
