Robert check out www.barnestormermodels.com They are based out of Henderson Ky and they kit a 1/4 scale ultimate biplane kit that is unbeleivable. They power it with the ys 140 and performace is just plain crazy. The kit is very complete and the guy who designed is the man who sells them. He is a very good pilot and his perfomance with this plane just remarkable. These are probably the best biplanes around. If nothing else check out the website for the cool pics!
