Waco Custom Cabin series
The Waco Custom Cabins were a series of single-engined four-to-five-seat aircraft with an enclosed cabin. They all had double wings, with the lower wings having a significantly smaller span than the upper ones. Nearly all had a radial piston engine. The exact model designation depends on the detailed design elements, like the engine, wing flaps and wing struts. Shown is an EQC-6.
