Just to report that Spark with the latest .600 FW (RC=.400), the FCC patch still works. I use the modded 4.1.3 GO app to set FCC on one Android device and then use my other daily phone with the official 4.1.5 to fly. Without OTG and on 5.8GHz I got to at least 900m without any connection issues. In CE mode the "weak image" warnings start at about 150m.

FYI: After installing the latest 4.1.4 (july 26) on another OS (LOS 13), it seems OTG actually still works.

Received an official 4.1.4 GO app (july 26 build, 132MB) update today and unfortunately OTG does not seem to work here any more! That still worked in the previous 4.1.4 build I downloaded as APK (22 july?). Can someone elkse confirm this?

I have no power measuring device, but like mentioned above I could fly Spark and OTG on 5.8GHz twice as far with the FCC config than without it, and without any signal weak messages.

With the latest 300 RC FW of Spark the FCC patch (50B) only works when using OTG, not on wifi any more.

I verified, and the FCC .DJI.config patch does not work on wifi any more, but it still works with OTG! Guess the same counts for the patch...
