The Waco Aircraft Company (WACO) was founded in 1920 as Weaver Aircraft Company of Ohio. In 1928/29, the company
changed its name to the Waco Aircraft Company. The company was a leader in the design of wood and fabric aircraft.
Waco built open cockpit biplanes to private owners. The UPF-7 was built in greater quantity than any single Waco
model that preceded it. As the PT-14 it was ordered by the U.S.Army for use as a trainer. Approximately 600 came
out of the Troy, Ohio factory between 1937 and 1942. The UPF-7 was a continuation of the Waco "F" series
which had been introduced with Model INF of 1930. The letter "U" identified the engine as the 220hp
Continental VW-670-6A, the "P" identified the wing and fuselage design. The "F" reflected
the principal design characteristics of the airplane. The ICAO Aircraft Type Designator used for the Waco UPF-7 is WACF |
