Ok updated everything including all my 4 battery sets with no issues. I should say when I connected the bird to my Mac it updated my new set of batteries to the current version on the inspire. This stopped the inconsistent firmware warnings.
As I wanted to use my IPhone X I continued and updated everything to the latest revision.
IMU and compass values looked fine after the update so I skipped that part of the process.
Flew two battery sets everything appeared fine until I functioned the return to home when she was about 500 meters out, the bird started to turn and the camera flicked round facing to where we had just been. At first I though she was heading in the wrong direction but she was heading back it was just confusing with the camera orientation. Did this every time I functioned the RTH. Second thing I don’t like, it seems to take a couple more seconds to shut down after left stick down stop is activated. It also tilts up up on two legs did this both times
I2 has never done that before although my I1 does this occasionally.
