The fs 17 was a test glider for a lying pilot arrangement of the technical flight group Stuttgart .
History and construction
The airplane was built in 1937 in wood for flight tests with high acceleration forces. In order to be able to withstand high load multiples of more than 14 g , a hydrofoil spar was created that combined the features of box and double spars and could also absorb torsional forces. The pilot lay on his stomach in the open fuselage of the aircraft under a transparent canopy with a brace under his chin; the control stick was mounted in the direction of the longitudinal axis for elevator deflections. There were air brakes at the stern. The first flight took place on March 21, 1938; the test series was continued with the B9 .
