    Lightbulb Hw fast with 21 or 29 tooth pinion?

    I was wondering how fast the xo1 would go with 2 traxxas 3s lips, unlocked, with a 21 or 29 tooth pinion. I also would like to know what pitch these have to be... I also am wondering if my engine would get too hot running a 29 or 21 tooth pinion in there. (stock spur)

    Pitch is Mod 1.

    With the stock spur, the 14T pinion provides 50mph and 34T provides 100mph roughly. My estimate would be 21T = 67mph and 29T = 85mph
