Now thats pretty slick. Tell you what though Ranigirl, if that keeps you entertained, then the 1/10th and 1/12th scale you assemble model R/Cs would be total nirvana for you. The speeds are freakin awesome, and the offroad cars, my old off road buggy has 1.5" of suspension travel. The off road buggys are a blast.
We also used to race indoors on carpeting in the winter time. I had a 1/12th team associated RC12L on road suspension car. This was straight up nascar style road racing. 4 cell packs, and sealed motors, coupe bodies were the rules.
