You'll see the results when the wing separated from mine as well as my input on the tail-heavy problem on one of those Kit-Building forums.

Mine is now my oldest, still-flying plane and I bring it out every time I go flying.  It must have over 100 hours on it, and it's still great fun.  It's not too pretty anymore, but hey, it flies great!

Good luck!
