Established at Berlin/Johannisthal Aerodrome after First World War, Sportflugzeugbau Rieseler built a single-engine single-seat light sporting parasol monoplane with a two cylinder Haacke engine which was put into production by Stahlwerk Mark at Breslau. A two-seat version, the R.IV/23, was subsequently developed.

The Rieflin Headless Aeroplane Co Hydro-aeroplane of 1912 set a world’s record for sustained hydro-aeroplane flight over water when piloted by Fred C. Eels on June 25, 1912 over Irondequoit Bay, New York, seventy-three miles in 1:21:00, at an average speed of fifty-four miles per hour. Eells’ flight was cut short when his supply of gasoline gave out and he dropped his machine to the bay. The best previous record for sustained flight was forty-six miles.

Keith Rider was a designer of the 1930’s air racing era. “Jackrabbit,” as it was called by its last racing owner, started life as a model R-5 and first appeared at the 1936 National Air Races. Its owner, Dave Elmendorf, painted it a cream yellow and gave it race number #22, which he had used on his Wedell Williams racer the previous year. The “Elmendorf Special” placed third in the 500 cu. in. event with a speed of 224.551 m.p.h.
The ship was not seen at the 1937 races, but was entered in the 1938 Nationals by its new owners, Marcoux and Bromberg. It had been rebuilt and sported a new black and yellow paint job. Race number #22 was retained but the name was changed to “Jackrabbit.” It was flown to fourth place in the 550 cu. in. event with a speed of 192.50. “Jackrabbit” last appeared at the 1939 races but did not race because of engine trouble.

Built in 1931, the Rider R-1 was racer San Francisco II, piloted by Bob Clampett and Ray Moore, registered NX52Y.

It was modified as 1933-34 Bumblebee (p: George Hague, Earl Ortman) and did not reappear until the 1938 Nationals as 260hp Bushey-McGrew B7M1 Bumblebee, re-registered NX98Y.
