Schweizer developed a line of gliders starting in World War II. The 2-31 was not intended to be a motor glider, but rather a light aircraft utilizing some glider and sailplane technologies, common parts with other Schweizer designs and an affordable price as a result of using smaller powerplants.

 

A two-seat version of the 1-30, the Schweizer SA 2-31 first flew in July 1960 but not put into production due to competition in the light aircraft market. No further motorgliders were built by the company until 1982.
