Not really, I have almost no practice in ATTI mode and still maintained a cool head when steering mine in ATTI mode next to a rock face with some stalactites above it, over water. Then I flew out to the ocean, but of course it gained GPS on the way out and set a home point in the middle of the ocean. XD It's all about keeping calm when you are working difficult situations. In another I misgauged the wind and the drone, despite sport mode, was crawling back to me very slowly. It looked as if the battery was going to run out before it could make it back. So instead of panicking, I started to look for some open clearings to land on, and then new ones as I kept passing the clearings as my Trackimo would've made it easy to figure out which one it was in. Fortunately I made it back, but with 3% battery.
