12/15/2021. Remarks by
Johan Visschedijk: "This aircraft was designed and built by Professor Adolfo Yakstas, a member of the
AVEX. The aircraft was constructed entirely of wood and was fitted with a 40 hp Praga B2 two-cylinder horizontally-opposed air-cooled engine (a design from the late-1930s!). The wings came from the Focke Wulf FW-44 J Stieglitz, a model produced under license in Argentina by FMA (Fábrica Militar de Aviones or Military Aircraft Factory).
