most brushless car in the right hands will out perform a nitro car. plus the bl system don't require any tunning as the day goes on. once u have ur gearing set for ur vehicle, it's just charge and go.
for ex. the track I raced at last week had 6 xxx-t/t4's and 1 nitro xxxt. the ele were all bl powered and the nitro was driven by a very good 1/8 scale racer. there was a tough battle for last place between the nitro and a kid that had just started racing this year.
