The airframe was initially built as a seaplane powered with a 60 hp LeBlond 5-D engine, which was exchanged with a 90 hp 7-D when later converted as a landplane. Span was 34 ft, length 25 ft, useful load 535 lbs, Vmax 105 mph, Vc 85 mph, Vso 30 mph, and range 400 miles. In 1929 Capital Aircraft Corporation was relocated in Royal Oak, Michigan, and was renamed the Royal Aircraft Corporation.
