RC Goblin
The RC Goblin is a small remote controlled helicopter that can be used on several missions in the Grand Theft Auto series of games. It has no actual weapon attached to it but in San Andreas and Vice City there is an electro-magnet at the bottom of the helicopter that can be used to transport objects from one place to another, like bombs (remember the mission in Vice City where you had to destroy a half contructed building for Avery?)
