Ragin' RC is a side-mission in Grand Theft Auto: Liberty City Stories. It is unlocked after the mission Driving Mr. Leone. It is located in Belleville Park, Staunton Island. It is triggered by entering the TOYZ van parked next to the boat house.
This is the hardest RC Race in the game. The terrain is hilly and when it rains, it's hard to control and at the mid-race track has a bridge where it is hard to pass. Just control the RC firmly and avoid unnecessary movements.
It is only a one-lap checkpoint race, with three levels to do. Completing level one gives you $1,000; completing level two rewards you $1,500; completing level three awards you with $2,000. Overall completion bonus is $500.
