You should try an IMU calibration. The IMU will influence the hover stability, a compass calibration won't. I'm not sure you'll see any improvement, but the IMU is central to hovering good. Make sure VPS is turned on too.I bought a P4 refurb from New Egg and it doesn’t seem as stable as my P3A. It’s a bit jittery and won’t hold position very well. I’ve done compass calibration and checked it out in DJI assistant, which it seems okay.
Any suggestions?
Thank you-
You will likely notice the P4 won't have the range your P3A has. I was disappointed in my P4 range when I got it, less than a mile range most the time, even with the 32ch hack on Ch30 and 4mbps bit rate. The Mavic Pro and P4P work much better for range.
