That being said, I have been on a mission where the mavic could barely keep up with the wind. It struggled along going maybe 0.5 to 1 mph (I was watching the speed on my controller). I could see the Mavic and I still had signal. Then the winds slowed down (or the Mavic flew into an area away from the gusts). It started to go at normal speed on its mission, around 10 mph away from me and I knew I would be losing signal after a minute or so (I've flown this mission multiple times before). This freaked me out because I felt that if the head winds returned and slowed the Mavic down to a crawl again after I had lost signal, it might just sit there, trying to fly it mission and unable to move. I would have no signal to tell it to return home. It would just sit there until the battery ran low, then it would try to automatically return home. But at that point, the drone may be too far away to make it back home with the available battery, and it would be lost. The lesson: be very careful about flying Litchi missions in high winds beyond signal's reach.
