RE: Phoenix ?
Archived about the plane, info from Jon Lowe.
Phoenix 5 used the wing and tail from the Phoenix 4, more side area for knife edge, published by American Modeler magazine. Kitted with fiberglass fuselage, foam wing by numerous people. Also a 40 sized version was kitted with a fiberglass fuselage. TONS of these were built. Wing Manufacturing has the molds and is kitting them.
