April 1 is right around the corner. But on a serious not, I may remember some of this circulating, pardon the pun, in Q-performance posts of the past, along with some other scimitar designs like those developed by a Lancair flier who used to frequent some of our Quickie West coast fly-ins, the Elippse propellor developed by Paul Lipps.
