Jim,
Palmer Plans from Calif has a set of the 131" Herky bird. I just got mine in December as a birthday present for about $96.00, I think, postpaid. You can find him on the internet or any RC magazine. Five sheets of paper 3' x 6', and I have only found one mistake in his drawing so far. Suggests a lot of use of foam board but I found that heavier then soft balsa, square inch for squqre inch. And he stresses , "keep it light". Let me know if I can do anything else for you.
