The Model B is probably the least known of the Waco company's projects.
Developed in 1939, it was not only the company's first cabin monoplane, it was also in the same league with other great designs of the time such as the Spartan Executive, the Kinner Aister or the Clark GA-46, to name but a few.
Designations found in different places refer to the three-place cabin project as the RFB or the SFB. In typical Waco fashion, these codes indicate two possible engines: a 110 hp Warner Scarab or a 300 hp Pratt & Whitney Wasp Jr. The latter version was planned for both mail and passenger use, but with the war's outbreak and the post-war surplus or military types, the project was abandoned.
Interestingly, the name Waco was revived in the 1960s with types such as the Sirius, the Minerva, the Meteor or the Vela—none genuine American designs (being borrowed from French Wassmer and Morane, or Italian Frati types), of which the Model B could be considered the stillborn ancestor.
Below: a three-view arrangement I drew using some eBay photos of original plans as a reference.
