    not fast enough

    my brushless is all stock and i have slipped in the 2 3s lipos. As i have read with these batteries it should do 65 right? well mine only went 52.3mph. so is it the gearing ratio or tires or what??

    Also, what are the batt specs? You must have at least a 3s 5000+mAh 30C (40C+ is desirable). Not to mention what growler87 just said: you need a 24 pinion and a 54 spur.

    I have found their hardened pinions (12T & 13T, 32P, 5mm bore) to be very good.
