    Pinion Gear Ratios

    So the stock pinion gear is 13t and i wanted a boost of speed nothing to crazy just enough to be noticeable, and that id be able to run safely and maybe permanently. I hear the 19t it comes with is too crazy. So i was wondering what are some gear sizes you guys run good speed and torque.
    I wanted also to know if a 15t or 16t would be much different because right now on 13t i get 41mph on 3s lipo

    I have only run 2c Lipo and generally have good results with a 15t or 16t. However, it cogs at low speeds with that. Since I often go for walks or hikes with my son and his 2wd Slash, the pace is slower. Because of that, I usually just stick with the stock 13t. Oh, my spur is 52t if memory serves...

    Is go up to 15t first and see how you like it. The pinions are fairly cheap and easy to change out.

    Remember your motor temps will rise with larger pinions.
