Boy, you picked a tough one. My quick search shows that you are correct, no plans or kits. I really don't think a DC-3 kit would be much help. The tail looks DC-3 but it was actually from the DC-2 which is a little different. There is a guy here in the forums that will design plans from 3 views for so much an inch of span. He delivers CAD plans that can be cut buy the lazer cutters. You might enquire here to see if someone can set you up with his contact info.

And no, I can't remember ever seeing anything on the Bolo in any of the RC periodicals. I don't thnik the bolo is "Sexy" enough for most of them to bother with. It sounds like an interesting project, let us know how it turns out.
