I got a "No Signal" message, the red one top center on the app. The image turned gray and froze for a bit. After about 10 seconds the RC reconnected and I flew back and did a RTH about half way back which worked. Was the "No Signal" error the RC not connecting, or the WiFi (video down-link)? Also a related question, does the map data on the app come from the WiFi also. So if WiFi goes out but not the controller connection, will the map still show me whats going on. Thanks.
