Has anyone had a problem where your P3 won't take off and reports that the IMU is still initializing? The status indicator in the App says everything is fine and ready to fly as GPS, but as soon as I try to start the motors I get an error that the IMU is initializing. I also checked the status screen and it said the IMU was normal and tried recalibrating the IMU and compass. So far nothing will make the IMU initializing error go away and it will not take off with the error. It flew perfectly fine just 30 min before. Then I swapped batteries and now it won't take off.
