Note: Waco civilian designations describe the configuration of the aircraft. The first letter lists the engine used, the second the specific type, and the third the general series. The coding system was changed in 1929 with several letters reassigned, and later with the introduction of the Custom Cabin series, the third letter 'C' was initially replaced with C-S (Cabin-Standard) and finally S. The numeral suffix represents the first year of production if it is 6 or higher (6=1936), or a sub type if 2 or less. Thus EGC-7 is a
Wright R-760-E2 () engined, cabin biplane airframe, custom cabin model first manufactured in 1937. Many Waco Cabin Biplanes that were originally sold as civilian aircraft, were impressed into military service in World War II. The
United States Army Air Forces classified theirs regardless of type as
Waco C-72s, with type letters identifying specific models. Other countries used other designations for their own Wacos.
Open cockpit biplanes and monoplanes ; Waco Cootie:Single seat biplane/parasol monoplane, 1 produced, then re-built ; Waco models 4 through 7: Used many Curtiss JN-4 parts with new interchangeable wing panels and powered by a
Curtiss OX-5. ; Waco 8: First Waco cabin biplane, powered by

Miss Pittsburgh giving joy rides, c.1930 ;
Waco 10: Most produced model of any Waco aircraft, 1,623 built between 1927 and 1933. Refinement of Waco 9 with
Curtiss OX-5 V8 engine. Redesignated
GXE by Waco in 1928. When letter designations were used, a final letter M indicated it was a mailplane, and the middle letter of S indicated a straight "Hershey bar" wing, while a T indicated the model was a taperwing, with the chord at the wingtips being less than half of the root chord. •
