went for a hike and was pretty sure i would lose signal flying out from the trees, created a litchi mission to fly out for me, sure enough, lost signal, when the mission came around to return, signal returned and came back perfectly [emoji1377]
Glad it worked for you. I like that the mission will continue even if the RC or app dies. Just keep in mind that winds in the mountains can be variable and unpredictable and GPS signals may get weak in a canyon. If you encounter a strong enough head wind on the return trip it would just fight it until it runs out of power.
