Built in Germany, the 1911 Eugen Wiencziers Renneindecker a very advanced monoplane with a very sleek fuselage which consisted of a metal tube only. The two wheel undercarriage could be folded back to the fuselage. The machine was intended as a two-seater, where the pilot sat enclosed and the passenger sat in a saddle just at his back on the steel fuselage, just like horse riding.
