Boeing PT-17 "Stearman"


The Kaydet, the two-seater biplane introduced by the Stearman Aircraft Division of Boeing in Wichita, Kansas, in 1934, became an unexpected success during World War II. Despite its almost obsolete design, its simple, rugged construction made it ideal as a trainer for novice pilots. The Kaydets had fabric-covered wooden wings, single-leg landing gear and an over-built welded steel fuselage. Only radial engines were used. Between 1936 and 1944, Boeing built 8,585 Kaydets, in all versions, plus the equivalent of 2,000 more in spares.


Kaydets were widely used airplanes. In addition to sales to the Navy and the Army Air Corps, they were sold to Canada, China, the Philippines, Venezuela, Argentina and Brazil for both military and civilian uses. Many were still in service in the early 1990's. Their slow, low-level flying capabilities made them particularly suitable for crop dusting and spraying.

The U.S. Postal Services features the Stearman Kaydet trainer on its classic aircraft postage stamps.



The Weaver Aircraft Company was founded in 1920 by George "Buck" Weaver, E.J. "Sam" Junkin, and Clayton Brukner. The trade name Waco (rhymes with taco) was coined from the title letters of Weaver Aircraft Co. Originally located in Lorain, Ohio, the company later moved to Troy, Ohio, drawn by the concentration of aviation related businesses that had sprung up around nearby Dayton, home of the Wright Brothers. The first Waco YMF rolled out of the Waco factory at Troy Ohio in early 1935. In late 1942, Waco ceased production of powered airplanes.


In 1983 the founders of Classic Aircraft Corporation envisioned their childhood dreams coming true with the reincarnation of the Waco YMF Biplane. In the history of aviation, no company had ever taken a fifty year old design and manufactured it new under the original FAA type certificate. To accomplish this mission they hired experienced aeronautical engineers to re- draw over 1400 drawings and build new tooling for production. This was done while maintaining the sanctity of WACO.S original design. The WACO YMF is not a .rebuild. or a .kit plane., but a brand new FAA certified production aircraft.

The first new production WACO YMF Classic rolled off the assembly line and received FAA certification under the original WACO type certificate in March of 1986. Today.s production aircraft has been greeted with overwhelming enthusiasm for its craftsmanship and the sheer joy brought to so many by making the thrill of flying in an .open-cockpit. biplane a reality.

The first Waco UPF-7 was rolled out of the Waco factory at Troy, Ohio in June of 1937. The UPF-7 was designed as a pilot trainer, both for primary student training and advanced training phases, including aerobatics. 600 UPF-7s were manufactured between 1937 and late 1942. Most were delivered to civilian flight schools participating in the Government's Civilian Pilot Training Program (CPTP) to train thousands of civilian pilots as a backlog in case of war. The U.S. Army Air Corps acquired 14 UPF-7s, which were designated YPT-14. The CAA (Civilian Aeronautics Authority-predecessor to the FAA) ordered 31 UPF- 7s; these were assigned to government inspectors to monitor civilian aviation operations.
