The technology of F1 is what keeps me glued to the TV every race. Well, that and the cars, tracks, flag girls, you know the deal. But when our F1 cars linup we have to buy the gas, the food, pay the entry fee, etc. We have a faster F1 class for those who like the speed. I have used the tuned 540's and the red dots but I just seem to keep coming back to the $18 'cans to race with my buds. Sometimes fast is not as fun.
