I have a Mini 1 and hadn't flown in for some time and of course it needed firmware updates and compass calibration. Over the past month or so I have flown about a dozen times and almost every time I need to re-calibrate the compass. A couple of 360's horizontally and vertically and it's good to go. No issues. I am basically flying from the same location each time and there isn't any obstructions or metal objects to affect the process. Have the new firmware updates in the last few months caused any issues? It's not a big deal to do it and is probably a good thing to do but I am just trying to understand the change.
