My copter with PIXHAWK was working great after finishing autotune for all 3 axis. I flew it several times with no problem. Today, I took off as normal in Alt Hold mode and it was very jittery and was erratic with the altitude too. I tried to land it but it came down rather suddenly and just flipped over.
I will attach the log to see if someone can help me understand what suddenly went wrong. MissionPlanner.log (500.1 KB)
