Anyone have any clue what...the..heck...happened? NOT what the log says it was, because NOTHING was above it or beside it, or within area to get in the motor and make it straight drop dead like that.
** This post is completely wrong **
Assessment was made without realising that the pilot was using a non-standard flight mode.
Correct analysis is further down the page.
I have a few clues.
Video is useless for analysing this flight incident but the story is very clear in the flight data.
Here's what your data really looks like: https://www.phantomhelp.com/LogViewer/Q5MHNYU3LGF7LOEU7D3M/
Your Mini had the same old uncommanded descent problem that's plagued this model since it was released.
Yours was running Firmware 1.0.5 which was supposed to fix it but cases like yours still show up.
Your Mini showed very poor altitude stability and control for much of the flight.
I'm surprised you didn't notice it much earlier.
There was plenty of evidence of a serious problem well before the crash.
There's too much to list every incidence so here's what I see from halfway through the flight.
From 7:06.5, left stick full down but the drone climbs from 17 ft - 330 ft.
From 7:44, left stick full forward, drone fails to climb
From 7:54.9, left stick full forward, drone fails to climb, then loses altitude from 370 ft - 222 ft
From 8:49.5, left stick full forward, drone fails to climb
From 9:24.4, drone sinks while hovering
From 9:34.6, left stick full forward, drone fails to climb
From 9:49.1, left stick full forward but drone loses height from 226 ft - 143 ft
From 10:05.9, left stick full forward, drone fails to climb until 11:00.7
From 11:00.7, left stick full forward but drone loses height until 11:34.3
From 11:49.3, left stick full forward but drone loses height
From 12:09.7, drone sinks while hovering until 12:13.2
From 12:28.9, drone sinks while hovering
From 12:47.6, left stick full forward but drone loses height until 12:53.3
From 13:18.6, left stick full forward but drone loses height from 269 ft - crash
13:48.6 - crash
