Just put this on the Inspire forum too. I've only just realised why I could get my Inspire camera to pitch up/down but the pan/yaw seemed to have stopped working. Previously on my IPad , I had been operating my Phantom 3 which obviously has no pan/yaw function. If you then go straight to operating the Inspire , even though you change to "connect to Inspire" on the app, the yaw function does not work. You have to completely shut down the app and reopen it to get the yaw function to work. Obviously unless you do this the app still thinks it's in 'Phantom mode'
