To the people having short range transmitter problems after the last update, which was myself, this update has appeared to help at least somewhat. Previously I couldnt get 400 feet no matter how hard I tried. Just took it out this morning and got a thousand feet distance. About 15 feet high striaght ahead right over a small pond.
Still not anywhere near the 1km that they advertise, nowhere near the mile that some people claim they are getting without any mods. It is good enough to get me through my vacation and then I will send it in. Still frustrating though. Really wish DJI would say something official
