Yes, I used WiFi Analyzer on the phone and the channel graph on Freeflight6 to confirm that the 5GHz channels 36-48 had no traffic on them, used FakeGPS to put me into somewhere in Massachusetts and then Freeflight opens up the rest of the 5GHz band for you to use.
If you ever get up to Da Lat, do me a favour and take a 5 minute video from directly above the roundabout at the end of the lake (with the metal VW and the Bus in the middle) looking straight down from as high as you can get it, I missed out because the Anafi chose to put itself into picture mode from video and I didn't notice it wasn't recording all the time I had it up there
