I'm running a 500cm frame with 11" rotors. It flyes but the navigation modes seem to be a tip suprised, that INAV 3 seems to have some troubles, when I turn on the 3D GPS+baro position hold (NAVPOSHOLD). It beeps 3 times and does also drift away, but the docs don't mention anything about beeps. Has anybody an idea what the problem might be?
There is no obvious problem in the blackbox log (BTW can I get a full log of warnings?). All sensors calibrated properly and GPS 3D fix. Nav safe is green before takeoff.
