The Gruppo Costruzioni Aeronautiche GCA.3 Eta Beta is virtually a tandem two-seat scaled-up version of the earlier GCA.2 Dumbo, retaining the V-tail assembly. The Eta Beta appeared in 1952, and was designed for both training and touring roles.
The fuselage is an all-wood stressed-skin structure and the wing is an all-wood monospar structure with a stressed plywood skin. Cantilever spring steel main undercarriage legs are fitted, and the enclosed cabin is provided with dual controls and HF radio.
