This is an old thread but instead of starting a new one I will use this one to ask if anyone can supply me a copy of the plans for the Elder Bipe, are at least full scale drawings of the interplane struts. I picked up a built one at an estate sale but it does not have the interplane struts. (The ones out on the outer part of each wing.). I would perfer the plans of course because there is a lot of information on them I might need as I put this plane into flying status.
