P.Lewis British Aircraft 1809-1914 (Putnam)

Flanders F.2 and F.3

   R. L. Howard Flanders was one of A. V. Roe's earliest assistants, having joined him when the triplane pioneer was making his first flights at Lea Marshes during the summer of 1909. Flanders afterwards accompanied Roe to the 1909 Blackpool Meeting, together with E. V. B. Fisher, and then teamed up with John V. Neale at Brooklands, designing the tiny Pup monoplane for him.
   The following year, on 1st August, 1910, he started to draw up plans for his own monoplane to carry the powerful 120 h.p. A.B.C. engine. Construction of the airframe was started on 1st October and continued until 26th May, 1911, when work stopped owing to the non-arrival of the specified engine.
   The day after, on 27th May, a new design was commenced, based upon the four-cylinder 60 h.p. Green. Construction started on 6th June, 1911, and the machine was finished two months later on 6th August, making its first flight on 8th August, 1911. Testing of the F.2 was carried out at Brooklands by Ronald C. Kemp.
   The F.2 was a single-seater of sound construction and of graceful appearance, and was flown for the next two months until, in October, it was reconstructed for participation in the contests for the British Empire Michelin Cups Nos. 1 and 2, in both of which it was piloted by Kemp, but was unable to register any success. The machine was redesignated the F.3, and alterations included the installation of a second cockpit to carry a passenger in front of the pilot, and also the provision of larger wings of 42 ft. span and 200 sq. ft. area. The same 60 h.p. Green engine was retained, and it drove an 8 ft. diameter Regy propeller. A silencer was fitted, and the pair of radiators operated on each side of the front cockpit. The F.3 was flown at first without a fin, but a small fixed surface was added after testing was carried out by Ronald Kemp and by E. V. B. Fisher.
   Following several months of flying, the F.3's career came to a tragic end when it crashed at Brooklands on 13th May, 1912, killing both the pilot, Fisher, and his American passenger Victor Mason.
