I know I am gonna get a good slapping on this but here goes. From what I have read so far I don't need to add anything to use this app. other that the app it self. Now I now there is a add on for the older models but it doesn't say anything about the newer models. I am trying to use this on the Ipad Air,. Everything works fine but it can't find the aircraft...lol...like duh. Do I need this add on >>> http://www.dji.com/product/ipad-ground-station
