I finished reviewing the log files you posted;
Your log does show that telemetry was lost near a pond after being hovering for a while, but,
The log does not show that
Home mode was engaged at any time.
Please keep in mind I'm no expert on this, this is just my interpretation of what the Remote logged.
Having said that, it seems the H had been reporting unusually high altitude data. Previous flights recorded top heights of over 175m (574ft), during this particular flight it also shows
a lot of Barometer calibrations performed by the IMU during the entire flight. During the last minute or so until telemetry loss it recorded a height of 200m (656ft)
just curious: were you really flying that high?
Chronology of events (sumarized):
16:48:59 - Motors Start, flight mode:
Smart
16:49:04 - Takeoff
16:49:04 - 16:52:06 - Regular flying no incidents
16:52:06 - 16:52:03 - Hovering in place, yawing left and right.
16:53:00 - 16:53:03 - Roll +100% Pitch -100% (right stick all the way left/down)
16:53:03 - 16:53:06 - Roll 0% Pitch -100% (right stick all the way down)
16:53:06 -
Aircraft telemetry lost (traveling @11mph)
16:53:06 - 16:53:18 - Pitch -100% (right stick pulled all the way down) [16:53:08 - 16:53:12 - camera tilt from 0 to -90]
16:53:18 - 16:53:19 - Thr -100% Pitch -100% (Left stick all the way down, right stick all the way down)
16:53:19 - 16:49:30 - No stick input (both sticks in neutral position)
16:49:30 - Remote log ends
Also this is the final path of the aircraft from the point where it was
hovering to the point where telemetry is
lost.
So this is what I can make out of the log files you shared, I hope this is somehow helpful.
Greetings!
