I am having issues with a generic quad, on px4 v1.9.0 stable. Especially interested in POSITION mode.
Unit was previously using ARDUPilot, flew well and predictable in all modes, most importantly LOITER.
I frequently get “Failsafe Enabled: no local Position” before the autopilot dumps to altitude mode, despite good GPS fix.
Even, when in POSITION, the position hold is very unstable, drifting around as if there is no GPS fix.
Any guidance, would be much appreciated.
