Just chiming in with experiences . My
P4 hit the top of some trees and fell to the forest floor. All I had to do is leave my app turned on , on my tablet and start walking . Even though the battery fell out of the drone on its way down, the map on my tablet (DJI GO) took me right to it. This is also true with my Parrot Disco . As long as you dont shut down and take your controller and phone/tablet , you should have no issues finding its last known spot. P.S. My
P4 was fine , just bent up and I changed out the shell. The Disco landed itself in the desert , without any damage.
