The Four-Star is my favorite plane, hands down. I loved it so much, I copied the design and made a coroplast version called the Cor-Star (search the SPAD forum for info). It's such a versatile design, I have bashed it into a bipe, and am now working on a twin version. First pic is my Four-Star, followed by my Cor-Star, Cor-Star 2, and Cor-Star Ultimate bipe. You can't go wrong with this plane!
