It happens at 125 miles per hour. That’s the speed at which the sound of the rushing wind drowns out the growl of the Great Lakes 2T-1A-2 Sport Trainer’s 180-horsepower engine. Conveniently, it’s also the recommended entry speed for loops and other over-the-top maneuvers, so the change in sound signals it’s time to pull. Firm back pressure on the stick brings three positive Gs that quickly lift the nose up through the horizon and towards the fair-weather cumulus clouds far overhead. Glance left and right at the checkerboard wing tips for alignment, then relax the back pressure and wait for the moment that open-cockpit fliers fondly anticipate: floating weightless at the top of a loop while gazing upward at the Earth. Its external dimensions, Lycoming IO-360 engine, and Hartzell constant-speed prop are the same as its predecessors, but differences in the new and old airplanes are more than skin deep.
