I just saw that the recommended engine for the Piper Pawnee is a .46-.52 two stroke (Hobby Zone), and that it has an 80" wingspan and weighs 8-9 lbs. It sounds to me like a .46 wouldn't be enough to adequately pull this plane. Am I mistaken?
It would fly, but not well. I'd personally go with a .62 - .72 four stroke. Some guys that have gone with bigger engines have complained about it being very nose heavy.
