Little Willie
The Little Willie is a mini helicopter available in Grand Theft Auto: Vice City Stories. It has working machine guns that fire when the circle button is held down. You are able to buy one for $5000 on the top balcony of The Clymenus Suite safehouse located in the eastern Vice City.
It's name is a reference to the famous Gyrocopter "Little Nelly" used by Sean Connery's 007 in the film, "You Only Live Twice." It is also a reference to the World's first tank, also named Little Willie in 1915.
