BBudWalker replied to the thread Crashed dji air 3s.My apologies. My attempt at brevity seems to have backfired. I didn’t say or mean to imply that tumbling was normal flight. This appears to be the behavior usually seen with simple propulsion loss. A collision followed by thrashing about would...

BBudWalker replied to the thread Crashed dji air 3s.But, we do have GPS velocity data. That's the xSpeed and ySpeed data that the GPS receiver obtains from the doppler shift. xSpeed is north speed and ySpeed is east speed. hSpeed combines xSpeed and ySpeed. The direction of flight can be obtained...

BBudWalker replied to the thread Crashed dji air 3s.Is it possible the Air 3S came close to the tree, managed to pick up You're right. The point was that the Air 3S wasn't launched that close to the where the incident occurred. The tumbling that began at 5.85 secs is orderly in the sense that...

BBudWalker replied to the thread Crashed dji air 3s.I prefer to base my analysis on numbers. To that end I was able to integrate the horizontal speed to determine the Air 3S travelled 4.6 meters before it started tumbling and then an additional 1.1 meters before the recording stopped. The Air 3S...

BBudWalker replied to the thread Crashed dji air 3s.True enough. But, the Air 3S didn't, on average, slow down any. The velocity variations are what is normally seen with the tumbling. Also note that obstacle avoidance was enabled but isAvoidingObstacle is False. I'm still going with, just...
