I completely agree with Mike's timeline. That is exactly as I know it. IMO, Dave had very little to do with the design of the Tiporare, other then maybe a few suggestions. It was a way to kit a "Curare" that some thought prettier and without royalties to Hanno. I do have to disagree with Mike on one thing. Hanson could frame up more then one airplane a week! He was fast! and his shop didn't have much in the way of power tools. I think he had a band saw and Dremel jig saw and that was it.

World's were in Doylestown, PA in '71, in Italy in '73.

BTW, Dick once told me that the name came from the WW1 song, It's a long way from "Tiporare".
