History

The Sukhoi Su-31 is a Russian single-engine, two-seat aerobatic aircraft designed by the Sukhoi Design Bureau. It has low wings and a retractable tricycle landing gear for easy maneuvering during takeoff and landing.

The aircraft's design also includes an all-metal construction, making it strong enough to withstand the rigors of aerobatics.
