I'm Way Cooler, WACO Mouse Pad

The 'F' series was popular with private owner pilots for sporting and other uses and continued in production through the late 1930s. The tandem cockpit UPF-7 version was adopted by the Civilian Pilot Training Program and continued to be built in numbers (over 600) until 1942. The YMF of 1934, which had a modified wider and longer fuselage, was returned to production in March 1986 by WACO Classic Aircraft of Lansing Michigan as the YMF-5. Over 100 YMF-5s have been completed by WACO Classic Aircraft and the type remains in low-rate production. Considerable numbers of 'F' series biplanes, both original and newly built, remained in service in mid-2009.
