Should have seen me circling that convoy.
Just need to trim it properly for the hover-hold to have enough input to actually hold. If you're drifting, press and hold the trimmer, manually correct so it stays in hover and release. Hover-hold will take care of the small adjustments needed to
stay in hover; it can't bring you into one while flying at 80km an hour (not a good one anyway).
Up and running, be there in 30mins.
