I took my drone to Europe this summer I had no problems whatsoever but my strategy was simple all I did was find an out-of-the-way place to lunch that was suitable for the shot I was trying to get and I just went straight up and straight down I did not go forward left or right just to reduce the risk and if done discreetly Your risks of detection are minimized. This is the gonzo style of drowning that worked well for me And I got some great shots I know this may not work for everybody
That's fine for photos but how is it for videos?
Timelapse might look okay, just hovering in place mostly.
A lot of times, it's great just rising above foliage, trees and other things which obstruct the views.
