The Waco F series was a range of American-built private pilot owner and training biplanes of the 1930s from the Waco Aircraft Company.
Development
[Bearbeiten | Quelltext bearbeiten]The Waco 'F' series of biplanes supplanted and then replaced the earlier 'O' series of 1927/33. The 'F' series had an airframe which was smaller and about 450 lbs lighter than the 'O' series, while continuing to provide accommodation for three persons in tandem open cockpits. A similar performance to the earlier model was obtained on the power of smaller and more economical engines.[1]
The initial models were the INF (Vorlage:Convert Kinner engine), KNF (Vorlage:Convert Kinner) and the RNF (Vorlage:Convert Warner Scarab), all of which had externally braced tailwheel undercarriages. Many further sub-models followed with more powerful engines of up to Vorlage:Convert.

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.[2]
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.[3] Over 100 YMF-5s have been completed by WACO Classic Aircraft and the type remains in low-rate production.[4]
Considerable numbers of 'F' series biplanes, both original and newly built, remained in service in mid-2009.
