About the Great Lakes biplane
The Great Lakes 2T-1A is a two-seat open-cockpit aerobatic biplane. The design dates from the late 1920s, and new production in the 1970s gave pilots a classic-looking biplane with a modern Lycoming engine. The 2T-1A-2 version has a 180-horsepower fuel-injected engine with inverted fuel and oil systems for aerobatics.
It is flown for sport aerobatics, training and the simple pleasure of open-cockpit flying.
