Fokker F.20

The Fokker F.XX 12-passenger transport had an elliptical-section fuselage instead of the rectangular form of previous Fokker transports. The cantilever high wing was of wooden construction and the fuselage a steel-tube structure. Power was provided by three Wright Cyclone R-1820-F radial engines, one mounted in the nose and the other two carried on strut assemblies under the wings. The main landing gear units retracted rearwards into the engine nacelles. The F.XX was the first Fokker transport aircraft to have retractable landing gear, and the whole design showed much greater attention to aerodynamic refinement. Named Zilvermeeuw (Silver Gull), it was flown for the first time in 1933 and handed over to KLM for operation on services from Amsterdam to London and Berlin.

The F.XX was much more modern design than previous Fokker high-wing monoplane transports, but the advent of the low-wing twin-engined Douglas DC-2 and DC-3 airliners soon rendered it obsolete and only a single example was built. It was later sold via Air Tropic to the Spanish Republican government and was used to maintain liaison between Madrid and Paris during 1937. Its ultimate fate is unknown.

With today's Electric engines for model airplanes with its large wing, thick airfoil would be a perfect design for a Scale flying model . On the real plane you can see the stringers in the fuselage I could easily imagine the FokkerF-20 in stick and tissue with 1/16" stringers , a 48"Wingspan etc...I suspect this had been done and there might even be a kit!! .

Hi Robert, you're right, it's a shame. There is a model in 1:72, for nearly $ 10000 (Bel-Air Models). Maybe you could show some pictures if you've finished the Fokker? I also want to (scratch?) build this model, though I am not very good at making things out of wood, maybe I can use the old Novo F.VII3/m's wing.

It is a pity there is no plastic modelkit of this elegant plane, as far as I know ! Now I'm building a model from scratch ! (Balsa wood , etcetera ) Scale 1/72. Robert.

Do you have any comments about this aircraft ?
