The Dr.I enjoyed some success in combat, being extraordinarily maneuverable, but deliveries to the Fliegertruppen were inhibited by engine shortages and the need to replace the wings of all early production aircraft, manufacturing standards of which were considered unacceptable by the Idflieg. The original V5 was brought up to production standards and delivered as a Dr.I, and 320 series Dr.Is were delivered to the Fliegertruppen. One was supplied to the Austro-Hungarian MAG concern.
Four prototypes with more powerful engines were completed as V7s. One of these, with an eleven-cylinder Oberursel Ur III rotary of 145 hp, participated in the first D-type contest at Adlershof, attaining an altitude of 16,405 ft (5,000 m) in 15.5 min. Two V7s were delivered to Austria-Hungary, one with a 160 hp Siemens & Halske Sh III rotary and the other with a 145 hp Steyr-built Le Rhône, and the fourth was fitted with a 170 hp Goebel Goe III rotary.
This replica was built by Hank Palmer and Louis Wilgus and was registered to the Rhinebeck Aerodrome Museum on November 22, 1994. Powered by a modern radial engine, instead of the original rotary engine, the aircraft is finished in a mixture of markings similar to those seen during WW I.
