 Lomcovak

A Lomcovák (or incorrectly spelled Lomcevak) is a family of extreme aerobatic maneuvers where the aircraft, with almost no forward speed, rotates on chosen axes due to the gyroscopic precession and torque of the rotating propeller.The word originates from a quote by the Czechoslovak aerobatic pilot Ladislav Bezák's mechanic at the 1958 air show in Brno, Czechoslovakia.
