How about my ever favorite-Sig Smith Miniplane? It doesn't do many 3D manuvers, but it's still a kick in the pants. I discovered last monday that she does a great inverted flat spin!

I power mine with a Saito .56. If I build another one, I think I'd use the Saito .72 instead. Even with the 4stroke that's in her, she still needed weight in her nose. If she needs weight in the nose, I'd rather use the extra power too.

It is a builder though.

(A GP Super Skybolt would be a kick too!)
