I was tested the issue against my Mavic pro and the Mavic has no issues. The P4 Pro on the other hand dropped my fpv out at about 200 ft altitude. When I finally did get it back after moving the antennas and bringing it down to an altitude of 120ft. It seems to be an ongoing issue? I’ve recalibrated the compass multiple times in different areas to try to rule out interference when I calibrated it. I’m just wondering if this is an issue anyone else is having?
