The Schweizer SGU 1-2 was a United States, amateur-built, single-seat, glider that was designed by Ernest Schweizer and constructed by the Mercury Glider Club between 1930 and 1931.

The HVSC used the 1-2 as a training glider while they used the prototype Schweizer SGU 1-7 for soaring[1] The club named the 1-2 "The Brick", a reference to its low performance.
[1] The success of the 1-1 and the 1-2 led the Schweizer brothers to continue on to design and build improved gliders, including a single SGU 1-3 the following year and to form the Schweizer Metal Aircraft Company.
