The Arado SC I was a biplane trainer developed in Germany in the 1920s. It was based on the S I but powered by a far more powerful inline engine. Accordingly the structure received considerable strengthening. The aircraft was intended for the clandestine military flying school at Lipetsk but it was not accepted for this service. Instead a small number were built for the Deutsche Verkehrsfliegerschule.
