The M-Squared Breese is a large family of high-wing, strut-braced, pusher configuration, tricycle gear, ultralight aircraft produced by M-Squared Aircraft of St. Elmo, Alabama in kit form, for amateur construction.[1][2][3][4][5][6][7][8]

Design and development

The M-Squared line of aircraft was started in 1996 when a former Quicksilver Manufacturing employee, Paul Mather, decided to offer retrofit kits to convert the Quicksilver II from cable-braced wings to a strut-braced configuration with jury struts. The kits proved popular and Mather expanded to market complete aircraft based on the basic Quicksilver layout. The first two aircraft in the series were the two-seat double surface wing Sport 1000 and the two-seat single surface wing Sprint 1000.[1][2]

The series all share similar construction featuring a bolted aluminium tube structure with the flying surfaces covered in pre-sewn Dacron sailcloth envelopes. All models are open-cockpit, but some have optional streamlined pods available. All models use tricycle landing gear and steerable nosewheels.[1]

The Breese 2 DS and SS have been accepted by the US Federal Aviation Administration as approved special light-sport aircraft.[9][10]
