Zeppelin-Lindau (Dornier) Rs IV
   Last of the war-time Dornier flying-boats, the Rs IV was launched in October 1918, construction having started the previous January. In cross-section the hull was much narrower than formerly, and lateral stability on the water was achieved by lifting-cum-flotation surfaces, which were later to become a famous Dornier flying-boat characteristic, in use right up to the Second World War and later termed sponsons. The high-slung fuselage was now metal skinned, and a much simplified tail assembly of cruciform pattern was designed.
   With the narrower hull, the power eggs perforce were closer together and were slightly staggered to allow maximum-diameter airscrews to be used. This feature improved asymmetric flight characteristics. After the Armistice No. 8801, which was Rs IV's Naval No., was dismantled during 1919.
   The lessons learned by Dornier from this four-year research programme were culminated in the many successful commercial flying-boats built between the two World Wars.
