Refinements of the R I soon resulted in the R II in 1921, from the outside almost indistinguishable from its predecessor. A major improvement in the design was removable wings; entire aircraft could be stowed very compactly on a car trailer in order to make it roadworthy. The R II had such a good maneuverability, flight characteristics, and handling qualities that the company “Stahlwerk Mark” in Breslau agreed to start a series production of it and of all of its successors, based on an article published in Flugsport, repeated the above description and added a list of specifications. Of interest is the maximum weight of just 230 kg with an empty weight of 165 kg , leaving room only for light-weight pilots. A drawing of the machine very similar is given with a photo of the engine. . Therein, the total weight is given as 290 kg (639 lb) and the engine power as 22 kW
