You are on the ARF page so I think you mean assemble rather than build. If this is the case try a Sportsman Aviation 60 size Waco Bipe . I have not flown mine yet but others have given it positive reviews. It was built very nicely and would have been a bit of work to make the compound curves between the cockpit and the rudder. I need another radio or at least a flight pak to get mine together. Theres a string about them currently running in the ARF section. There are some nice pix there.
