Clintjc1,
Welcome back to the addiction!!! Unfortunately there aren't too many warbirds that are good for a 2nd plane. As an instructor I see students all the time want to get into a warbird as fast as they can (hey, I think a slick P-51 is a sexy plane tool. very hard to resist), but unfortunately most of the time take the warbird home in a plastic bag. I'd say to get you a good low wing plane (4*40/60, tiger 2, etc ...) and get some more of you skills built up. There isn't any reason why you couldn't start building a warbird while you fly the 2nd plane. After you get nice and slick on that then I'd think about moving up to a warbird.

Now, with that said, I don't want to be a total stick in the mud. If you're really set on doing it there are a couple out there that might fill the bill. As said before, the T-34 Mentor is pretty forgiving. I've heard that the Hanger 9 -P-40 flies like a sport plane, but I don't know yet. I'm in the process of doing a review on this plane and haven't flown it. I'll be more than happy to let you know how if flies once I get it in the air

Hope this helps

Ken
