What is the best thing to do when I lose GPS lock? Ideally, I suppose I should learn to fly the thing in non-GPS mode. However, I don't see any way to intentionally get into non-GPS mode. It seems to fly the same way regardless of where the S1 switch is set--and that is in GPS mode. So, how do I learn to fly in non-GPS mode? Given that I can't fly well at all in non-GPS mode, what is the best thing to do if I lose contact with the satellites?
