The Standard Cabin Wacos were beefy 4- or 5-seat biplanes with full-sized bottom wings as compared with the smaller bottom wings of the later Custom Cabin series. They were used as everything from executive transports to bush planes. Built from 1931 until 1937, they had a variety of different configurations and engines with a corresponding variety of Waco company designations. Dozens of these planes are still flying in the hands of proud vintage aircraft enthusiasts.
