Rustler
The Rustler is a WWII fighter plane in Grand Theft Auto: San Andreas, based on the North American P-51 Mustang or or Hawker Tempest.
It is extremely fast and has very good manoeuvrability, as expected from a WWII piston engined fighter. It has 6 machine guns in the wings.
It is used for most of the missions at the flying school, and for missions with Mike Toreno. It is found in one of the open hangars at Easter Bay International Airport or at the Verdant Meadows airfield.
