Ok so the whole CE and FCC thing has me a little worried also so I have started to investigate this myself. As someone who travels the globe a lot I didn't want to be limited with this CE 16dBm when there was a better option for the FCC 20dBm. I have heard a million different responses on this that it will be GPS specific its factory set and all the many others but I want a definitive answer before I commit to something that may not be able to be changed after purchase. A lot of my ariel work either comes from when I fly real helicopters or when I use my S900 hex but I ordered this due to it being a pretty good deal. My girlfriend lives in the UK and I'm from the states but I use her address for all my Post when I'm away working. I just received a reply from DJI stating that the controller will be self adapting. Not quite sure what that means exactly yet but I have asked for some clarity on it, Was also asked if I would be using this product in the states which I will be whenever I go back there to visit family. Will post their response as soon as I get one from the DJI team.
