This video shows two flights of my X-VERT drone in Multirotor mode. Three times during the course of the two flights it suddenly looses control for an unknown reason and flies erratically, twice resulting in a crash. These failures occur at:
2:12 (Drone flies erratically out of frame and crashes)
3:42 (Drone flies off erratically but is able to recover), and
4:22 (Drone looses stability and crashes)
This video is uploaded as part of a Horizon Service request.
