Boeing Stearman

The Mahora Aerobatics Club flies Stearman biplanes with an extra fuel tank mounted under the fuselage. Other modifications include covered landing gear, cowled engine, single cockpit (with the front cockpit either removed or the two combined into one, or simply covered by surface material) and squared-off rudder.

Interestingly, thousands of Stearman planes were sold to civil users after the Second World War, which may explain how Mahora Academy obtained the aircraft.

Trivia

 * The exact model of the plane is the Boeing-Stearman Model 75
