The SGS 1-26 enjoyed a very long production run from its first flight in 1954 until 1979, when production was ended. The 1-26 was replaced in production by the Schweizer SGS 1-36 Sprite. The 1-26 is the most numerous sailplane found in the US. [1] [4] In October 1963 a special issue of Soaring magazine was dedicated to the 1-26. Harner Selvidge ...
Schweizer SGS 1-23D sailplane. The 1-23 was first flown in 1948. The Schweizer SGS 1-23 was a world class competition and record setting glider between its first flight in 1948 and the end of its production in 1967. [9] In the 1950s and 1960s the Schweizer Aircraft Corporation designed and manufactured the very popular SGS 1-26 and SGS 2-33 gliders
The 1-36 was conceived as a replacement for the One-design competition Schweizer SGS 1-26, when production of that model ended in 1979. [7] The 1-36 was also the last glider model that the company would manufacture. The completion of production of the 1-36 in 1982 marked the end of an era that started in 1930 with the Schweizer SGP 1-1. [1] [4]
The SGS 2-33, indicating Schweizer Glider, Sailplane, 2 Seats, Model 33, was designed by Ernest Schweizer. The aircraft was a derivative of the 2-22, which in turn was based on the SGU 1-7 single place glider of 1937. The 2-33 retained the 2-22 and 1-7's metal wing, single spar and single strut arrangement. [1] [2] [5]
The company identified that there was demand from private owners and especially clubs and commercial operations for a simple, rugged single seat glider with greater performance than the 1-26. [3] In service the 1-34 has proven to be a popular club aircraft and ideal for the completion of badge flights. If a greater number of 1-34s had been ...

The wings are removable using the same design as the 1-26. The engine uses a cowling with exposed cylinders like a J-3 Cub for simplicity and cooling efficiency. Wing mounted spoilers were retained from the 1-26, allowing steep low-speed descents at about a 5:1 glide ratio. Three sets of wings were tested including a set from the model 2-31.
The 17.9 aspect ratio wing provides a glide ratio of 28:1 with the propeller feathered, and a minimum sink speed of 3.16 feet/sec (0.96 m/s). [1] [3] The USAF Technical Orders indicate a glide ratio of between 19.3:1 and 19.7:1. [11] The SGS 2-37 was marketed by the company as being suitable for the following roles: [1] [3] Sailplane trainer
