No flight plan test is, eh, lazy ;-)
I still don't think that your bird was flying straight.
It did that just before you followed the shadow and the "road"
The center of the video is NOT pointing into the direction your drone was going.
I wanted to know, if your slightly right course was deliberate.
Technics, to keep the "one shot" without tumbling around, "right, left, centered", most steady.
Or if you did that (right?) by accident, moving the right control stick a bit out of center, to fly it following the shadow.
I guess that you watched the display only, at that time.
I would love to have the flight record play back option from the Go4 on the Anafi!
