I don’t know if any actual testing has been done to verify it, but Witt claimed that the fuselage produced a significant amount of lift. Did you allow for that in your analysis?
Tim Buttles has more champ than cub in his plane but he used flat plexi panels for the windshield. Not to be like a tailwind but because it's $$$ cheaper than a molded windshield. Square off the tail, which I've seen cub clones with squared tail feathers. The pressure cowl is there so add tapered rod gear and you'recustomize it with Wittman Tailwind design elements (windshield, tailfeathers, Wittman style landing gear). I love the cowling used on most of the W-10s with Lycoming engines, don't know how to make a cowling like that work on the front of a J-3 style fuse/firewall?
Yea whats not to like about it for us sub-farts getting a bit long in the tooth? That Sky-Coupe wing with a 35 kt stall should make for nice docile handling. I was fortunate to score a set of plans for it on E-bay a couple years ago.The Daphne is a great example of what it takes to make an LSA out of a Tailwind: 55% more wing area and a 33% thicker airfoil implemented with an entirely different wing and strut structure. All that's left is the Tailwind look, which is not a bad thing if that's what you like and LSA is the mission you have to fulfill. Here's an article on a Daphne from 1966.
Yea and a composite foam and fiberglass build long before anyone else was doing it.Scott ol' ironside could be used as visual example too:
I think it is in restoration now ?Sadly it was destroyed a couple years ago.
