The Avro 638 Club Cadet and the basically similar 643 Cadet Mk.II were produced in the 1930s. Both types have identical wings, undercarriage and tail unit, but the wings of the Cadet have more stagger than those of the Club Cadet to provide improved view from both cockpits.
Engines used were the 130 hp DH Gipsy Major 1 and 135 hp AS Genet Major radial.
