Chasin' RC is a RC race in Grand Theft Auto: Liberty City Stories at the south end of the terminal in Francis International Airport. Here, there's a van which you can trigger the Chasin' RC mission. It is a lap checkpoint race; It is the easiest one of three RC races in the game, as the surface is smooth and flat, but only gets harder when you need to adjust your speed and the direction when you're getting at the 3 ramps. Sometimes, when you didn't adjust the speed and direction correctly, the RC may tumble or flip and could get overtaken by the opponent RCs. Just watch the final ramp as the ramp is near the plane, gain a lot of speed when you're near at the final ramp.
The race's name is a reference to the slang phrase "chasin' arse".
