[Overdriven]

I remember NASCAR experimenting a few years back with RC heli's (single rotor) to take shots from the infield in the turns. Kind of a dangerous place to be for a human. Its funny I was just watching WRC rally highlights yesterday and was thinking the helicopter must be annoying to the spectators. Even a large event like that could be covered by a few strategically placed rc heli's, probably for less cost than renting a real chopper too. Although the rc may have trouble keeping pace with the cars on the longer straights.
