The Rustler is a WWII fighter plane in Grand Theft Auto: San Andreas, based on the North American P-51 Mustang (wings, canopy, fuselage) with features derived from the Curtis P-40 Warhawk (empennage, propeller, air scoop). It is fast and has very good maneuverability, as expected from a fighter. It has 6 machine guns in the wings but is very delicate, as even gently scraping a wing against an object can cause the plane to explode. Unlike other planes in the game with mounted machine guns, the Rustler's machine guns do not automatically lock onto a target. This makes it more difficult for the Rustler to hit vehicles, even more so when the Rustler is moving quickly and will probably not have enough time to finish off the vehicle.
It is used for most of the missions at the flying school, and for a mission for Mike Toreno. It is also used at one of the checkpoint races in Las Venturas. It is found in one of the open hangars at Easter Bay International Airport or at the Verdant Meadows airfield and is a common sight in the air above rural areas.
It is possible to find a Rustler in the bottom floor of the police impound lot in Roca Escalante (alongside a Leviathan and a Hydra). As the plane intersects the ground, it is impossible to even enter the plane.
