So those logs show that it went a lot farther than crashing roughly where you took off from. Unfortunately starting at the grid 45.384500, -111.190166 that it showed the last reading isn't going to yield many results unless you get lucky and those trees there stretch up 314' above where you took off from. The AC was still flying at 5MPH, but you said you seen on the screen that it flew into a tree?
Looking at the terrain he was flying in, it looks like it is a hilly/mountain region, so there are big elevation changes. So running into a tree at over 300' above the takeoff point is fairly realistic in this case.
Looking at the log files, I think the we can very likely see the tree impact at the 3m 58s to 3m 59s mark. At this point in time, the VPS altitude sensors go from not registering any values (meaning it was likely >30ft above something) to suddenly registering values from 2ft down to 0ft. We can also see some sudden and violent changes in Pitch/Roll/Yaw at this point. It looks like it may have stabilized itself for a couple of seconds and then I think it likely hit something again in the last couple seconds of the log before it loses connection because we see the Pitch/Roll/Yaw values swinging wildly again in the last few entries.
I wouldn't be surprised if the aircraft isn't either in a tree or on the ground very near to the final GPS coordinates from the logs. 45.38449183 -111.191434
However, it looks like it would be some pretty tough terrain to find a little bitty drone.
I know it doesn't help to recover any lost footage, but I definitely would recommend opening a ticket with DJI if you haven't already to see if you might be able to get a replacement under warranty.
One recommendation I would make for anybody when their aircraft goes into ATTI mode is to try to fly it home (or to an alternate safe landing area) ASAP. I noticed at the 0m 27s point that the aircraft went into ATTI mode for a few seconds. At this point, I would recommend bringing the aircraft home immediately to check it out rather than continuing with the flight. Also, once it goes into ATTI mode, the pilot needs to try to take control of the aircraft. I know when it happens, it can seem like the pilot doesn't have control, but we almost always can see in the logs that inputs to the sticks results in appropriate movements associated with those stick movements. I've been there before and I know it can seem like there is no control by the pilot, but its the best course of action to try to save the aircraft.
mountainpics11, I wish you the best of luck in getting back up and flying very soon! |
