RC Baron
The RC Baron is a small remote controlled plane that appears in both Grand Theft Auto: Vice City and Grand Theft Auto: San Andreas. The RC Baron's red color and name is based off the Red Baron, an ace pilot from World War I.
Vice City
The RC Baron is used for the RC Baron race. It is located on top of a multistory parking lot at North Point Mall by entering a Top Fun van.
San Andreas
The RC Baron is used in one mission for Zero where CJ uses it in order to help Zero to destroy Berkley's delivery system. The RC Baron has a machine gun, and self destruct capability, along with a fuel meter during that mission. The RC Baron is also used in an optional side-mission Beefy Baron.
You cannot obtain this vehicle outside the missions without trainers or modifications.
