Yeah the game uses mode 3 setup.
I fly RC planes / helis using mode 2 (and I'm UK) but I never really thought about the confusion it could cause. I guess cos I use the cockpit view, and the aviator setup has one of the sticks as your head so it's different enough to not interfere.
Hope there is button mapping tho. I bet everyone have quite different views on control setup. Offering 2 variations isn't going to please many! lol
