Rider R-5 Jackrabbit
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.
