Role: 4-5 place cabin sesquiplanes
Manufacturer: Weaver Aircraft Company
First flight: 1935

The Waco C series were the firm's first successful cabin biplane design, and was based on the F series airframe. The Model C series had a raised centre and rear fuselage to form a four-seat cabin which was entered through a door over the lower wing and had a rather ugly framed rear-view window dispensed with in the later standard cabins. The initial QDC model of 1931 had a 165 hp (123 kW) Continental A70 cowled engine and was fitted with a triangulated shock-cord tailwheel undercarriage.

1932 brought the OEC and UEC models which were powered respectively by the 210 hp (157 kW) Kinner C5 and the 210 hp (157 kW) Continental R-670. Continuous refinement and improvement by Waco Aircraft resulted in production of various sub-models continuing until 1939.

In 1935, Waco introduced its Custom Cabin series (which featured a sesquiplane layout without ailerons on the lower wing) and decided to differentiate between the Standard and Custom Cabin types by appending an S to the model designator. in 1936 the C-S was replaced with an 'S' signifying 'Standard'.

Operational history

The Standard Cabin series, with its cabin comfort, proved to be popular with private pilot owners. Many were purchased by small commercial aviation firms and non-aviation businesses. Approximately 135 Standard Cabins series aircraft of several sub-models are currently registered in the USA.

Variants

The Waco C series included all cabin models 1931-1935, and Custom cabin models from 1936, produced by the Weaver Aircraft Company (Waco), Advance Aircraft Co. and Waco Aircraft Co. in Ohio, USA.
