Floyd Neff of Monroe, Iowa built and still has a KR-1 with a corvair engine and a self designed/built PSRU. He flew it for almost 200 hour until he decided he was getting just a little to old for the hot rod. It has been reported that he did a 225 mph+++ high speed pass over the Knoxville runway. It was also reported that he has no aft CG problems but forward CG is another matter.
Floyd was the tech counsler of the local EAA chapter and a tool and die maker. If anyone would like to contact Floyd, email me off net. Brant Hollensbe bhollen...@mchsi.com
