I was flying the Phantom yesterday with no issues for the first 4 flights. The next one (compass recalibrate after battery change), I had 8 satellites on the ground and then 10 feet or so after launch it was 14. Then out of nowhere zero. It was slightly breezy so immediately she drifted. Never flying in anything but GPS mode, thank god I trained many hours with the X5C. As I was bringing her back down, the satellites came back. I landed, rebooted, recalibrated and the same exact thing happened. Does this sound like a defect? I could see dropping a few, but all 14 to zero is pretty scary. What if I was doing a Ground Station loop or something.
