Keith Rider was the designer of a series of racing aircraft. From the first R-1 to the R-6, his designs were based on low-wing slim aircraft powered by inline engines.

The Rider R-1 (and the closest R-2) was a cigar-shape metalic fuselage to hoist an inline engine with a fixed conventional landing gear. Wings were of wood covered by fabric.

The R-3 came eventually to a very different shape and name once modified from the basic accidented 1933 Keith-Rider R-3 : a very different final modification (by receiving a Twin Wasp Jr radial engine and redesigned wing) and great performing of the basic R-3 called Marcoux-Bromberg, in honor who financed the modifications. The Marcoux-Bromberg Special was always piloted by Earl Ortman. In 1938 he won the Golden Gate Classic, set a record from Oakland to San Diego of 1 hour and 48 minutes and participated at the 1938 and 1939 Thompson Trophy.

The next two racers were powered by a 6-cylinder, inverted, inline, air cooled Menasco engine. The only significant difference between the R-4 and R-5 was the R-5’s wings were two feet longer, adding 80 pounds to the empty weight of the aircraft.

A last engineering gave the unfortunate Rider R-6 before World War Two stopped air racing and put an end to Keith Rider activity.

Only one airframe was built for each of these racing aircraft.

This category is for :

• Rider R-1 (reg. NR51Y);
  
• Rider R-2 (reg. NX52Y);
  
• Rider R-3 then later Marcoux-Bromberg R-3 (reg. NX14215);
  
• Rider R-4 Firecracker (reg. NX261Y);
  
• Rider/Elmendorf R-5 Jackrabbit (reg. NX264Y);
  
• Rider R-6 (reg. NX96Y).

This page lists all films that feature a variation of the Keith Rider's design.
