At the slope with a lovely Multiplex ASW-27B, using the Google Maps app, proving it works with home-made GPS from the rc-thoughts design. There are not any no-fly zones at this site so the maps app is more of a novelty value, though if the lift collapsed as it sometimes does and you had to land a long way down this would help you to find the model!
Dave is constantly updating the app software to cope with my requests so this flight proved the latest version, and that I had got my static map downloads correct as the system picked a correct map once the GPS worked out where we were.
