[QUOTE="cologne_seethe_mastery, post: 17933, member: 3221"] Ok, I am answering to myselve and writing in here in case someone has idea what to do. I did more testing. I even figured out what VPS altitude is ... so I cleaned all sensors below aircraft and front, calibrated IMU and GPS before flight. Wifi is back to 5.8GHz,does it comes automatic ? flying low altitude 1-3m its showing almost correct altitudes due to VPS altitude ? Anyway I figured out why its starting RTH on its own. When I climb up 10m-20m-30m altitude readings on my screen wobbles 0.3m (red colour) to its assumable currrent altitude ie. 35m. When I pull joystick down if its showing 35m aircraft reacts normally but because altitude wobbles around red 0.4m ie. if im pulling stick down aircraft thinks it close to ground and starts landing. Atleast now I know why RTH / landing starts automaticly. What next ? How can I get my altitude readings normal ? Should I do clean install on spark ? How about DJI should I contact them ? Many questions, what would you do ? [/QUOTE]
