hi there!
i took part in last years world championship of helicopter flying near niederöblarn/austria and i can recommend it to you. i flew for the swiss team.
there are very famous mountain ranges, as the "dead mountains" in german totengebirge, the landscape is beautiful.
i found out the adress in niederöblarn, its:

take a look at the link "alpenflugzentrum", there you will find more information. the lady at the desk speaks english so u could give her a small call and reserve a booking.
have fun! i'm off to new zealand to go heliflying..;=)
