I am new to DJI and decided to start with a low end Phantom 1 to use for practice before I step up to the Inspire 1. I have been flying the UAV for about a week with great success and really love the product. Yesterday, I went out to fly and after turning on the controller and then plugging in the battery, the yellow light just starts blinking and nothing I do will change it. I have installed the latest FW & SW. Nothing will make the yellow blinking light go out. Any suggestions on what to do will be greatly appreciated.
