If you can scratch-build, I've posted plans for a slimmed-down 1/4 scale Cosmic Wind ("Little Toni", but you can paint it green and call it a "Ballerina" if you like) ... surf to http://www.home.earthlink.net/~stinger4/. There's a choice of ModelCAD or .DXF formats. Also proposed rules if you want to run it against the Great Planes Shoestring, World Models Midget Mustang, etc.
