Another vote for the Skybolt. The Stearman's a pretty plane but it's built to fly "scale" whereas the 'Bolt's a sport's model and easier thrown around. I built mine from a GP kit (they're no longer made) and started off with an ASP 1.20 4 stroke. It was always a heavy plane and suffered at my hands somewhat and was rebuilt a few times thus making it heavier but it still handled like a dream. I ended up shoe-horning an OS FT-160 Gemini engine into it with a 3 blade prop - and the plane loved it. I wouldn't go any bigger than a 1.20 on the ARF version though - mine was braced every way possible and was twice as strong (and heavy) as it needed to be.
