So, bought the Phantom yesterday and made about five successful test flights. Today we started it up, and the green and yellow lights were blinking. Went through the procedure to set the compass. Green and yellow lights were still blinking. Powered it up, and instantly lost control. It flew high and far away and disappeared. When we lost it in the sky, we shut off the transmitter, hoping it would return home. It didn't. Had a GoPro3 with Wifi onboard. What happened?
