It would be nice to have another ALT between 500 and 2000 for UAVs, maybe 1000 or 1,250.
500 is way to low for the fixed wing planes and the enemy and AI can usually detect and shoot them if they are that low.
If the UAV is set to 2000 then its undetected but even fully zoomed in you can barely make anything on the ground out because of the field of view.
I manually flew them until they were around 1,000-1,250 and that seems to be the sweet spot where I don't get detected/shot and yet I can still see the ground pretty clear while zoomed in.
The gap jump from the standard 500 to 2000 seems pretty big and 1 more should be squeezed inbetween.
