Heh, heh? fellow named Steve Eberhart posts and says he's "played around with
KR stuff in the past". An understatement, very much like Steve. He was one of
the developers of the AS504x series of KR-optimized airfoils and he built the
wind tunnel models. I believe John Roffey machined the tubular spars that the
airfoil models were built on and Mark Langford spearheaded the development
effort. There were others involved, of course? but the full story is at
