    Just got me new best friend couple of days ago and been going through the various modes.
    It's EVERYTHING I hoped to see and more . . . fantastic little bird, beautifully engineered and built, quiet, agile, a breeze to set up but . .

    This morning (3rd flight) I activated "auto-land" and it came down nice and smoothly to about 3 feet and stopped. Controller beeped I think and it said something like " Unsafe to Land - Please take over manually" . . or words to that effect. . . but it was in the middle of a paved open parking lot with nothing around it but my car maybe 10 feet away. . . so I just pull down on the stick and it landed fine. . . but it was going nowhere until I took over. It just halted in a low hover and waited for me to do something.

    Anyone else got any knowledge or experience with this?
    Thanks

    I'm still waiting for my bird, but it could be that on the initial take-off it didn't quite record an obvious Home Point, meaning that the underside cameras could not distinguish the actual zero-elevation-point, so it hovered when it got close. Maybe try taking off from some place that's not all gray, a grassy area, or a take-off mat with a big Target Bullseye on it? Just guessing.

    That could be why because I was asking it to land about 30-40 ft from where I took off but that should not have made a difference since I asked it to "Auto-Land" in a flat open space . . . not RTL

    Oh, not RTHome....look up Auto-Land in the manual.

    Sounds like it may have thought it was over water...

    Is there any gunk on your bottom VPS camera lens?

    Page 51 of the DJI MP Manual states that if the Quad detects an unsafe surface to land, it will hover and wait for Pilot to land it....

    There's a setting for auto evaluating of the landing surface, you can turn that off.

    I don't see it maybe I have to have the Mavic connected. I don't see any setting for auto evaluating the landing surface.
    I'll connect the Mavic up
    Thanks for your help
