The question has been asked here many times. Keep in mind the Tailwind is a serious hot rod, even with low power. That's the way Mr. Wittman designed airplanes, and the legacy is celebrated by the this group's members. It's a little like asking if you can make a Shelby Cobra into a slow car. Have a look at other light sport airplanes that push up to the full 1320 lb weight limit. They're typically around 130 square feet of wing area, the W-10 is 100 square feet. My quick calculations show that it would have to be built somewhere around 950 pounds max take weight to make the maximum stall speed. That's a big ask with the existing airplane. You could re-work the design with a larger wing, a different airfoil, lighter wing without plywood sheeting, (dual wing struts needed) etc. Then again it's already been done for you. Wittman's earlier design the Buttercup is already LSA compliant. Earl Luce sells the plans. http://luceair.com/replica_buttercup.html The lines aren't quite the same as the Tailwind, but you could easily make the same changes to the lower longerons, top forward tubes and cowl that Jim Clement has made. His Buttercup looks a great deal like a Tailwind. http://groups.yahoo.com/neo/groups/TailwindForum/conversations/messages/5 653 2 For the most part, those who have asked your question here before appear to have no interest in doing a Buttercup but it's by far the best way to go. It's highly impractical to make the Tailwind stall slow enough and keep it's top speed within the regs. Speed is determined by the airframe much more than the horsepower. I hope this helps your deliberations.
