 Calculations were done based on the fs31's fuselage to determine the optimal geometry and mass for the vertical fin and tailplane, which led to the use of the fin of a Schempp-Hirth Nimbus 3D and tailplane of a Nimbus 4D, though slightly modified to fit the fuselage.Furthermore, most of the control rods in the cockpit, the wheel brakes, and the rear lift pin tube were taken over from the Schleicher ASH 25.To create the wings, the wing molds of the Akaflieg Stuttgart fs32 were taken and extended inwards by 2,5 meters.
