i race the 720+ nt1, depends on tracks, nt1 4 big open tracks, 720 4 small to medium tracks, BTW i also race the 007, i just prefer nitro, because i hate getting beat bye guys, that have battery packs that i cannot buy, by that i mean, i can afford whatever they have but its hard to compete with someone who gets packs with WAY BETTER numbers that i do, and it would b impossible for someone other than a sponsored driver to get those same packs!!!
