    Taming a brushless 3S Rally

    Anybody done the Hobbywing brushless upgrade to the Rally? I'm running the little 4600kv motor and ESC, and when she's running 3S, she's uncontrollable.

    I'm guessing I should dial out some of the punch, and maybe go to a bigger pinion.

    Any suggestions on gearing? I'll try the 14T pinion first, to see if that helps any.

    At this point, I'm thinking more top end, less grunt off the line, since this motor is so crazy powerful, compared to the little brushed motor.

    Suggestions, folks?

    Anybody? Anybody?

    I find your lack of teepee disturbing.

    Heck with the stock motor and the bigger 7.2V NiH battery it becomes difficult to keep it in a straight line. Haven't ventured into brushless territory yet.
