The MB-1 Colibri first flew in 1965 and served as a development aircraft for the definitive MB-2 Colibri 2 that flew in 1970. These aircraft had all-wooden framework with fabric-covered wings and
plywood -covered
fuselages . The pilot's seat was enclosed by an expansive
bubble canopy . In 1976-77, Brügger built and flew an
all-metal version as the MB-3 . Many examples are actively flying in 2012.
The MB-2 is noted for its handling qualities.
