HI.
I was flying my Mavic Air to a train station 3km away.
See the screen recorder, please:
Video screen recorder
(0'49") After reach the station I stopped at 4km and then turned around and went back.
(1'02") Suddenly the camera drone lost its horizon and then, after a sharp hit (1'13"), it lost its GPS signal entering ATTI mode and fell 10 meters.
(1'26") Then it recovered, but no camera horizon, (1'41") then another strike, (1'44") then I activated RTH.
(1'49") After a few seconds another strike.
(1'58") At this point, during a good part of the RTH, the drone remained with the camera horizon not leveled, and made the return journey by walking sideways. All movements are not made by me, but by the drone itself!
See the map: aircraft seems proceed with bow forward but it walks by side!
See the camera horizon!
(2'54") I raise the camera. The aircaft continues to yaw left (I cannot do nothing... I'm in RTH).
(3'38") Aircraft tries to yaw in right direction but loses horizon.
I'm not sure of real direction... I have to believe the map and the decreasing distance!
I start to control the altitude, going to 25-30m (I'm on a high hill).
(3'58") Aircraft returns to yaw left.
(7'37") Aircraft starts to yaw correctly to right but camera loses horizon.
(8'10") Right yaw, right camera horizon.
No other issue from this point.
I stopped the RTH and recoved aircraft by hand landing.
After a few minutes, after battery change, I flew for 2 or 3 minutes in sport mode stressing the aircraft. No issue.
All normal!
What's happened?
Bird strike? Propellers (Master Airscrew) are perfect!
IMU?
Compass?
It was a beautiful day, there was no wind, app doesn't warns me anytime.
Anyway, the attitude meter (low-left side fo the screen) shows only a few wind from left to right (on the way, right to left at return).
This is the FlightRecord on AirData:
Airdata
How I can have other data, like motor speed (to see if was a bird strike?)
Thanks.
