RE: Cessena Kit - .40 sized
40 sized Cessnas are very popular these days, and the market demand is for the ARFs, not kits. About the closest you can get to a kit would be the Great Planes Cessna 182, which requires a considerable amount of measuring, drilling, cutting, fitting, and gluing. It can take more time to build the Cessna than it typically does for many kits, in fact. The Goldberg Heritage Cessna would be less challenging to build and fly.
