Hey folks. I have a new Phantom v1.1.1 and on the 4th day of flying it went black and dropped out of the sky. Only about 5 minutes into the flight. Fully charged battery. Batteries have been providing a good 12 minutes of flight time. No prior crashes. Everything was working fine with the flights on the battery used during the crash and with my two other batteries used before and after the crash. No mods to the copter and camera was not attached for this flight. All software was updated before the first flight a week ago. It was about 30 feet up and just went black - no lights or leds at all. I have been pouring through this board and Youtube for possible answers but have not found an anything. Can the Phantom be turned off in mid flight without landing with the sticks? A few scratches and nicks but luckily the machine still flies well. I popped in a third battery and everything was normal but still looking for any possible answers. Thanks for any help!
