Today there was a strange incident happened to my flight. Temperature was around +4. home point was recorded and flight started. but When I started my AC, it just flies away. AC was flying on it own, i could not control it almost all the time, when i pressed RTH, it was trying to come back home, but at the time of landing when it AC was 15 to 20 m height , it again tried to fly away, it happened 3-4 times.  Fortunately last 2-3 minutes I was able to control the height and AC crashed some 10 meters away from HOME POINT at the height of 20m. I could save my AIR, but this was absolutely strange.
I am uploading the logs. if someone can analyse the logs and tell me what was wrong.
