Alan, great you could join our discussion! I have a copy of your construction article and plans and, IMHO they are the most scale accurate RC plans available. I'd love to hear what sort of research went into the drawing of your plans. For example, on what references did YOU base the outlines?

I think it wonderful how the building of certain models develop a history over time -- with each generation of modeler standing on the shoulders of prior generations trying to take it to greater heights. Actually, I think the race is on for someone (most likely Achim Engels) to produce a full scale flying replica.
