Dayton Wright RB racer

A number of racing aircraft were developed that employed the monoplane configuration. Some of these aircraft had cantilever wings; others employed strut-braced wings; such advanced concepts as retractable landing gear were sometimes seen. For one reason or another, however, none of these monoplane racers was particularly successful. The Dayton Wright RB racer developed for the 1920 Gordon Bennett race was perhaps one of the most advanced concepts developed during the entire period.  The pilot was entirely enclosed in the fuselage, which was of wooden semimonocoque construction. The cantilever wing was constructed entirely of wood an employed leading- and trailing-edge flaps. These flaps in effect provided variable camber so that the airfoil section could be adjusted to its optimum shape for both high-speed and low-speed flight. This extremely advanced feature did not appear on production aircraft until the development of the jet transport in the 1950's. The landing gear on the Dayton Wright racer retracted into the fuselage in very much the same way as that used in later Grumman fighters of the thirties and forties.  

Although highly advanced for its time, the Dayton Wright racer was not successful in the 1920 Gordon Bennett race. The aircraft was somewhat underpowered and during the race had to withdraw because of a broken rudder cable. Unfortunately, the type was not further developed.
