Akaflieg Graz VL2 Kef ("Kef")

1923

The hangglider bi-plane „Kef" („Kef") was designed by the members Flödl, Pernthaler and Spies. It was the smallest Austrian airplane ever by that time. The rudder was fixed; the other controls were conventional. The body consisted of three struts forming a triangle. Parallel struts and cables connected the two wings. The pilot was sitting on a belt during flight. Take off was done by running. Systematic instruction with „Maulwurf II" („Mole II") and „Kef" was done on the mountain „Platte" near Graz.
