According to things I read on the internet concerning GPS reception, the general opinion is that clouds do not affect the GPS reception. Yet, when I fly my bird on most sunny days I get 10-12 sats. On cloudy days it is reduced significantly. Today was a very cloudy day and the most I got were 8 sats and while flying I actually dropped to 5 for an instant. Question #1: Does anyone else have this same issue or do I have a weak GPS component. Question #2: If you get GPS lock before the flight, then drop to 5 sats mid-flight, what happens to the lock? Is it gone and therefore a fails safe "go home" is going to travel to an unpredictable location?
