Fieseler F 4

The Fieseler F 4 was a two-seat sports and touring aircraft designed, built and flown by the Fieseler Flugzeugbau in Kassel in 1932. Fieseler created it after the failure of the F 3 Wespe, putting the emphasis on safety, quality, efficiency and comfort. It was a low-wing monoplane with a welded steel tube fuselage and wooden wings covered in aircraft linen, braced by profile wires, and its balloon-tyred undercarriage sat forward of the centre of gravity to reduce the danger of nosing over. Padded seats, adjustable rudder pedals and a luggage compartment behind the pilot added comfort. It first used a 35 PS Argus As 16 engine and later a Salmson 9 AD radial. It first flew in August 1932 and was shown at the German aerospace exhibition that October, priced at 5,900 or 6,300 Reichsmark depending on engine, but Fieseler suspended flight testing and abandoned production plans so the company could develop other types.
