The motor fault shows in file 2019_06_08_23_56_0 and appears that it flew about 30 feet before landing. The Mantis Q does not appear to have been powered off and was launched on the fateful flight about a minute later. All during that flight Angle mode is lost and the Mantis is flying in Manual mode and will therefore drift with the wind unless counteracted by pilot control.
I am attaching text files that extract some of the data found in the Mantis logs.
In the 23_56_0 file you can see launch at 01:33, and the Motor ) error and disabling at 01:42.
In the 23_57_1 file you can see the relaunch at 02:42, then at 02:52 you get an Emergency message 'Critical Navigation Failure - Check Sensor Calibr' followed by a Critical: 'No valid position, switching to manual mode'.
At 03:52 the Mantis attempts to re-enter Angle mode and with no valid position changes back to manual mode. Same again at 04:06, and 04:12.
At 04:42 another Critical: 'Manual Control lost' then regained and back to manual mode. At 05:00 and 05:04 a message is received that the Mantis is in the process of landing, then is returned to manual mode. At 05:07 a Critical: 'vehicle command 179' (possibly RTL) as the Home position is displayed. Then at 05:10 another Critical: 'vehicle command 176' (change to Angle mode ?) then a return to manual mode. Lastly starting around 05:33 are messages showing the Mantis trying to land with control still in manual mode.
The altitude was still rather high at time the file ended, but you should be able to have an idea of where it may have gone down. it was heading ENE during the last part of the flight.
You can see the start of where it was entering RTL then exited to Angle mode where it looped south then resumed flying to the NE.
The green shows the altitude ending at about 70 meters and the blue line shows distance from the Home Point ending about 270 meters distant.
I would contact Yuneec CS at Yuneec USA | Support and file a claim if you are within the warranty period. I am not sure what your settings were in the YuneecPilot app in regards to RTL settings. At the time of the sensor warning near the start of the last file, it may have been prudent to have landed and checked on the aircraft.
Were you using an iOS or an Android device to run YuneecPilot?
You can start looking at the last position shown by the yellow line, then in a direction along the last part of the flight path.
