Thrashin' RC is a side mission in Grand Theft Auto: Liberty City Stories. It is a checkpoint race around Hepburn Heights, Portland Island. The player has to race an RC Bandit (in the form of a miniature Bobcat) against three others. To start this mission, the player must enter a TOYZ van parked at the construction site in Hepburn Heights. The player must win the race to pass the mission.
Initially, the race only has one lap, but each time the player wins the race, an extra lap is incremented. The player can continue the RC races by entering the TOYZ van at any time.
