dornier do j wal 3d model

Dornier Do J (Dornier Do J Wal): The Do J had a high-mounted strut-braced parasol wing with two piston engines mounted in tandem in a central nacelle above the wing; one engine drove a tractor and the other drove a pusher propeller. The hull made use of Claudius Dornier's patented sponsons on the hull's sides, pioneered on the Dornier-designed Zeppelin-Lindau Rs.IV flying boat late in World War I. The Do J made its maiden flight on 6 November 1922. The flight, as well as most production until 1932, took place in Italy because of the restrictions on aviation in Germany after World War I under the terms of the Treaty of Versailles. Dornier began to produce the Wal in Germany in 1931; production went on until 1936.
