Just bought the Litchi App for iOS and absolutely love the interface. However, I did have a question/concern about sending it out on longer Waypoint missions. Knowing that my P3 4K will lose signal a few minutes after it heads out on a waypoint mission, what happens if the app crashes and/or if for some reason it encounters a mission error? I realize these waypoint flights are executed using GPS coordinates, but am a bit nervous knowing that my bird will be well out of controller range on longer missions. Litchi's website says the RTH feature will not work on the Standard or 4K if this happens. Have any of you had this happen, or does the app/flight go smoothly on each mission? If so, what did you do (aside from panic)? I'd hate to lose my bird midway through a mission that's 1+ miles away.
