Speaking of Tipo's, I have been tracing Dick Hanson's original Model Builder plans into autocad and decided to check the wing area. It measures out at 668sq.in. Being under the impression that the original design was 720sq.in. I then imported the plans from the Great Planes kit (referred directly to as the T720 kit in this thread) and checked it. That wing measures at 682sq.in. Both pdf's are scaled at 1:1 and known dimensions on them measure out correctly in autocad. Any comments or thoughts on these discrepancies?
A related question is what airfoil is used on the Tipo? Since I can accurately plot it from the coordinate data I would prefer to do that and get it right from the start.
