One of the classic cabin designs of the "Golden Age" of the 1930s, the Waco UIC was a very popular business aircraft.
Engine: Continental R-670, 220 hp (Smithsonian caption)
Waco began early 20s as Weaver Aircraft Co., Lorraine OH. Produced only a few aircraft and was relatively short lived. Clayton J. Brukner and Elwood Junkin, from original company, continued as Advance Aircraft Company of Troy OH 1925, although it continued to be popularly called Waco. Market was soft through mid 20s because of cheap availability of Jenny and Standard. Firm shrewdly determined what aviation community wanted and produced Waco 9 (carrying 2 passengers) which proved very popular. Capitalizing on its success and continuing to sense what buyer wanted, produced improved Model 10 which was even more successful. During late 20s, Waco said to have produced more commercial aircraft than all other companies combined. Depression saw appearance of Taperwing Model 10 with 220 hp engine and UIC, an enclosed cabin version which sold for about $6000; engine and customized changes increased the cost to $8-10,000. (Note: C in UIC denotes customized version, and S denotes standard version). UIC was comfortable and reliable and immediately became popular with corporate and business travelers. Initially, sold faster than it could be built with at least 70 sold in 1933. Could fly into many fields not serviced by commercial airlines and also gave the traveler freedom to set his own schedule. Despite Depression, "business" aircraft quickly caught on and several other companies soon produced comparable models, e.g., Stinson SR- 10. 44 Waco aircraft "went to war" as utility and trainer aircraft for Army and Navy. During WWII, Waco prospered by building CG-4 troop glider. At end of the war, however, Waco had only one design on the boards, "Aristocraft," an all-metal pusher propeller, strut-braced, model which failed to meet performance of popular Bonanza or Ryan Navion. As a result, Waco out of business as a major aircraft manufacturer.
