Which Rabe Bearcat? American Modeler Plans, or a later version, if so, which one?
Whatever version, recommend using the Bob Hunt lost foam technique for the wing. It is about the lightest way to get a fully sheeted wing and it will be true. Also recommend, whatever version, to do molded fuselage shells. All of Rabe's Bearcat are great fliers, but need to be light and have adequate power.
