The "Kulbit" (also known as the "Frolov chakra") is an aerial maneuver developed by Russian pilots in which the aircraft performs an extremely tight loop, often not much wider than the length of the aircraft itself. It differs from the traditional inside loop as it uses post-stall maneuvering capabilities,a type of supermaneuverability. Like most post-stall maneuvers, it demonstrates pitch control outside the normal flight envelope wherein pitch control is made possible by having aerodynamic flow over the aircraft's elevators or stabilators.
