Waco CSO

National Warplane Museum

The Waco CSO represents a classic example of early American open-cockpit biplane design from the golden age of aviation. Built for both personal and business use, aircraft like the Waco CSO offered private owners, flying clubs, and air taxi operators a combination of reliability, ruggedness, and elegance in the late 1920s and early 1930s.

Background

Founded in Ohio, the Waco Aircraft Company (Weaver Aircraft Company) became one of the most successful producers of civilian aircraft during the interwar period. The CSO model, part of Waco’s successful “C” series, was introduced in 1929 as a three-place open cockpit biplane powered by a reliable radial engine. It was marketed as an upscale aircraft for sport flying, charter service, and short-haul passenger transport — offering an unmatched combination of performance and style for private aviation of its time.

Use & Purpose

The Waco CSO was used primarily for personal transportation, barnstorming, business travel, mail, and charter flights during the boom years of early aviation. Its forgiving flight characteristics, rugged construction, and graceful lines made it a favorite among private pilots and small commercial operators. Even today, Waco biplanes are admired for their classic appearance and enjoyable flying qualities.
