This is a 42” wingspan 381 square inch .25 to .40 powered primary trainer. The airplane has a 3/8 thick balsa sheet wing. The sheet wing airplane is easier to build and if necessary to fix than the standard Ringmaster with the built-up wing. Unlike the Trainer II the wing and tailfeathers are glued into the fuselage. The larger airplane is much easier to fly than a 1/2A size airplane, and easier than even the Ringmaster Jr. Trainer. The airplanes have CAD plans with full size templates of all the parts.
