Thank you all for the answers. I read many articles on the forum. I realized that my compass is magnetized. I demagnetized the compass with a special device (cfixer) - the error disappeared.?
Hey. Help solve my problem. Yesterday, my drone landed because of a discharged battery - the drone landed on a road bridge. Miracle - I managed to pick him up from the road. After that, I always had a compass error and the drone itself goes into atti mode. What happened? How to repair it?
