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.
