"Two for the Show" is an article written on a neat 1/2A model Biplane. There is a full page scanable plan for this model with 19" WS and 19" length. Wing area is 132 sq in. Shows Cox medallion .049 or .051 engine.
Now heres the kicker. I have an ad in classifieds for magazines. This model is in American Aircraft Modeler from March 1972.
