What could be the reason for low height Loiter optical flow drift - log file? 4.4.4 Arducopter, Hereflow.
How sensitive is it to the surface texture?

Redo the inflight calibration, and update the accurate flow z position. test on another site.
low height performs okay. hmm, I am unsure if it is the blue surface or the FnScaler issue. Outdoor, loiter optical flow position lock is superb.
