I suspect that if DJI have decided not to sell it to America it'll be in the firmware that they can't take off in US territory, thereby rendering attempts to get them in from elsewhere somewhat futile, or at least a serious PITA to circumvent.
Surprisingly bold move from DJI today as reported here on DroneDJ... in which they have decided simply not to make the Mavic 4 available to the US ! :/ Apparently this not linked to the impending attempts to implement a ban on DJI but more in...
Skids are OK, (unless they take your drone over a weight limit you need to stick to) but mostly rendered unnecessary if you have a landing pad, which evens out most typical surfaces enough so that camera calibration doesn't hit the ground.
I think I figured it out. I was using a usb-a to usb-c cable. Switched to a usb-c to usb-c and it worked much better. Did order the 100w block msinger suggested. So that should make things better as well. Thanks all.
