Waco F series (RNF)
1 model built 1930–1931 · 35 on the US register today
The Waco F series, the smaller and roughly 450 lb lighter successor to the O series of 1927-33, introduced in 1930 and built through the late 1930s: three people in tandem open cockpits, two passengers side by side in front and the pilot behind, with similar performance to the Waco 10 on smaller and more economical engines. The first models were the INF (125 hp Kinner), KNF (100 hp Kinner) and RNF (110 hp Warner Scarab, ATC 311 of April 1930, about 150 built); later sub-models ran to 225 hp. The UPF-7 of 1937-42 and the YMF-5 that WACO Classic builds today are later members of the same series and have their own families here.
