My mini has been fantastic now all of a sudden it’s become unpredictable and irratic;when I lift of mm goes bit sidewards then settles(updates homepoint)but then when I fly it’s unstable-just dropped from 2 mtrs;hit the ground and also not as responsive;previously very precise;now on the verge of losing control;I recalibrated both compass and imu but didn’t help;;I have landed before it crashes(I have also changed both props on one arm after it going sidewards trying to take off and clipping wall-as I have said before all previous take offs were 100%,initiate lift off and it went straight up and hovered good ;now struggling to hold position;I’m showing 12 satellites;;help please
