Are you talking about a race track or a track race? If you want to do a race track then the (4wd) 1/8th buggies and some 1/10th buggies are gunna be the best. I currently have the team associated 8.2e 1/8th scale buggy and i freaking love it. Super fast, flies straight and level, and not to hard to control with a little practice. And at $500 it's not too pricey. If you want to do a track race then you should take a peek at the tank forum on this site and see if they have any speedy tracked models that they can recommend. I unfortunately know very little about that side of the hobby. Welcome to the forum BTW!
