Design and development

The early 1950s were the heyday of the SGS 1-23 design. From the time of its introduction in 1948, the production sailplane had dominated soaring contests in the USA.

employee Howie Burr conceived of creating an improved version of the 1-23 by using the existing fuselage and building a set of 17.10:1 aspect ratio wings for the aircraft. The span wings gave the aircraft a 30:1 glide ratio and a low minimum sink speed. Those performance figures are identical to the 1-23D. Burr finished the aircraft in his spare time, flying it first in early 1953. The 1-24 was ready for competition flying in time for the 1953 US Nationals, which were held at Harris Hill, New York. The 1-24 design was never certified and the sole aircraft that was built is an experimental aircraft in the "racing, exhibition" class and registered as N91888. The 1-24 is of all metal construction, including

wings. The design incorporated some innovative concepts in addition to the high aspect ratio wing. It had a shuttle weight that could be moved by cable through the length of the tail that allowed the glider to be trimmed anywhere between and .
