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 strut
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in c ...
s. The kits proved popular and Mather expanded to market complete aircraft based on the basic
Quicksilver
Quicksilver may refer to:
* Quicksilver (metal), the chemical element mercury

* Quicksilver, a bluegrass band fronted by Doyle Lawson
* "Quicksilver" (song), a 1950 hit for Bing Crosby

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.
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.
The Breese 2 DS and SS have been accepted by the US
Federal Aviation Administration as approved special
