Welcome Dave,
I once had the privilege of visiting your city. On arrival at the airport I was picked up by a colleague who took me down to the harbor. We walked into a little bar and he ordered us up a couple of Thunder Ale's. I'd been on a plane for the last 18 hours or something crazy like that but decided to be polite and have a drink with my new friend. It turned out this stuff was someting like 13% by volume and I'm drinking two pints of this stuff. I was totally ambushed my first day. But I got my revenge when I blew chunks all over his brand new car.
I love Australia and hope to go back there someday with my wife. I'll pass on the Thunder Ale though mate.
I've given some thought to doing R/C aircraft. If I were to do it I think I would go the same route as you and do WWI era aircraft. Probably a Jenny JN-4D or something. We'll have to see.
Take care and welcome to the group!
Dave
