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
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 pounds (200 kg) 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 (125 hp (93 kW) Kinner engine), KNF (100 hp (75 kW) Kinner) and the RNF (110 hp (82 kW) Warner Scarab), all of which had externally braced tailwheel undercarriages. Many further sub-models followed with more powerful engines of up to 225 hp (168 kW). The most powerful in the range was the ZPF of 1936/37, intended for executive use.
Operational history
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 remained in low-rate production to customer order in 2012.[4]
The WACO Aircraft Company of Ohio Inc had built three replicas by December 2011, which they designated MF.[5]
Considerable numbers of 'F' series biplanes, both original and newly built, remained in service in mid-2009.
