I've heard of him, but don't know the guy. He's here in Maryland too. Bill is on here from Maryland and he might know the guy.
On a related note... Floyd Presley is a long time Falconer from Maryland, and a few years back he wrote something about that hybrid in one of the Nafa publications. At the time I think he had been flying one for a few years and it passed away? He was interested in finding someone to make him another one. I saw the one that he had at a picnic briefly, and talked to him about it for only a few minutes.
