Thank you VietVet, that video is very nice and will surely be helpful to many people in this forum.
Actually my original post wasn't motivated by not knowing the modes (that I normally use with my Phantom and Spark), but more by the contraddiction between manual pages 23 and following (it's the list of intelligent flight modes for the Mavic2) and what is in page 67 (list of messages on the controller, it lists also terrain, course lock... that aren't in pages 23+).
That's why the suggestion to "read the manual" upset me, I had already read it so carefully that I found errors (and there are many more that that listed above)!
My
M2Z should be delivered Next Tuesday, so just a couple days more and I'll cross check myself.
BTW where is the area you shot that video? Looks very nice.
