The HD playback is interesting. It looks like the ac was in atti mode drifting rapidly downwind straight after takeoff. It was also flying backwards, so when the operator pulled back it flew away even faster. The stick movements seem to be consistent with the track, so he had controls until presumably he lost signal. It switched to WiFi for some reason.
Amongst all of the warnings, low battery finally came up with RTH - my guess is it couldn’t get back upwind.

You aren't reading the data correctly.
There's no hint that wind had any effect but there's plenty of evidence to show that the Phantom was flying uncontrollably as is very commonly seen in compass error/yaw error conditions.
If you think the joystick input matches the Phantom's flight, just look at 0:22.5 - 0:41.3 when he had his right stick centred but the Phantom accelerated from 18-59 mph.
Switched to wifi?
The P3 Standard is a wifi drone. It was never using anything but wifi.
Amongst all of the warnings, low battery finally came up with RTH - my guess is it couldn’t get back upwind.
Low battery??
There's no hint of any low battery warning and the battery is still healthy when the data stops.
Your guess about wind is incorrect - his Phantom was uncontrollable. |
