Rotor Turbosky is a helicopter that works for Dinoco. He is a Whirlybird Liftalot, a model considered as high performance. He is painted blue, with the Dinoco logo on either side above his doors, as well as the King's logo. He has a large black propeller, and two blue fins next to his "nose".
In Cars, Rotor appears at the end of the film, when Lightning McQueen fulfills his promise to his friend, Mater, by asking Tex Dinoco, the owner of Dinoco, for a helicopter ride, which is apparent at the end of the movie when Mater is flying over Radiator Springs, happily singing.
"A high-performance executive helicopter, Rotor Turbosky is ready at a moment's notice to get The King wherever he needs to go. He is faster, provides a smoother ride that those smaller whirlybirds, and is a proud card-carrying member of Team Dinoco."
