Arkbird failure after crash

Early this spring I had a major crash with my ASW28. It was my fault, I had not set the right settings in the waypoint mode. The crash was not recorded, so the clip in this video is only an illustration of what really happened. After a thorough repair I had a few flights, then strange things began to happen. I fly mostly in “Balance Mode” (lock direction and height), in this mode the plane began to behave unstable. After some less comfortable flights, I replaced the Arkbird 2.0 Lite with a new one from a building project.
When I made this video, I would include a screenshot of the update program ,showing the error when trying to update. Then the Arkbird suddenly would like to update anyway!?! Can anybody tell me if I can trust the old Arkbird, or should I dump it. Comments are welcomed."
