Steve-
I'm currently building one of these and also plan to use a Saito 180 that I have laying around. If you find out any other info, please jot it down. Also, if I come across any other info I'll post it. So far, the build has gone fairly well. I felt that some of the wing sheeting was sub-par, and quite a bit of the plywood was badly warped. Most of it I was able to get straight by the use of the doublers. I am a perfectionist, so maybe I am just being too picky. But, I thought I'd just put my $.02 worth. If there's anything else you'd like to know about it, I'd be happy to answer any of your questions.
