About the Zks-6

The Waco ZKS-6 is an American fixed-wing cabin biplane designed to accommodate a pilot and multiple passengers. Featuring a single engine and a traditional layout, this type-certificated aircraft is well-suited for both commercial and private operators seeking a reliable single-engine machine. Its foundational design incorporates a fabric-covered structure with metal frames and a fixed tailwheel undercarriage.

Originally evolving from earlier Waco cabin series models through a series of designations and subvariants, the S series developed distinct features such as ailerons linked by prominent struts and squared-off rear side windows, while omitting features like leading and trailing edge cutouts. During the Second World War, several examples were impressed into military service for liaison, transport, and instrument training. A number of these classic aircraft have remained airworthy into the current century, demonstrating enduring popularity among pilots.
