The M-Squared Breese 2 X/D Family of airplanes can be purchased as Certified S-LSA or E-LSA airplanes. The S-LSA version can be used for rentals and training but must be signed-off by an A&P mechanic. Both S-LSA and E-LSA airplanes have offerings in both single-surface and double-surface wing configurations. In this class of airplane, a single-surface wing provides greater lift but slower cruise airspeed than a double-surface wing. When floats are employed, single-surface wings get the airplane off the water more easily. The Breese 2 X/D airplane is configured with the Rotax 912ULS (100 hp) engine and has tremendous short-field take-off characteristics capable of lifting heavy payloads easily. They are without question among the most rugged airplanes available in their class.
