RE: Balsa USA EAA Bi-Plane
Joe,
Build it. Put ailerons in the top wing. If you use anything bigger than a 90 4-stroke, move the firewall back. It can take 3" movement easily. I put a 22cc gasser in the nose and moved it back that much. Still looks fine.
It's a good bird and fits (with the shortened nose) in my SUV fully assembled!
