Hi all, I was just curious I got my boy's some old school Ofna's top of the line back in the day but they tear up the street with the cones i set up so now I'm going to sign them up at the local hobby shop for the on-road oval comp. anyways any tips would be great I know theres alot of money racing on the track but kids are kids and I've been racing with them in the street trying to teach them traffic and hazzards but like I say'd kids are kid's and the throttle is max'd any suggestions before we start racing would be great..cause I really can't recall my first race day lol but it was dirt and everyone crashes lol, I just want to have a good show and no hard feelings if my boy's wreck sombody..
