    DeWalt 14.4 Gearing...

    I though I'd make this thread because after two hours of searching I didn't find a true good answer. What would be a good pinion to run on the DeWalt with the stock 68t spur gear? I'm leaning towards a 18t pinion, but I'm not 100% sure. I'll be running 80-90% in grass that sometimes can get rather tall. I'm really afraid the 18t pinion is too high gearing and it will kill run time, or ruin my esc/DeWalt. So, what gearing is everyone using with their DeWalts? I just want to get a feel for what I should use. Thanks!

    I ran 18/68 last years with no problem, that was with Proline Trenchers.

    I guess when I get to do the swap ill just stick with the stock size since I went down 2 teeth with the mudslingers

    Oh, I'm running Trencher X's, would that lower my gear ratio because of the smaller tire size?

    Ok, here is what I'm looking at.

    17 tooth pinion LINK

    18 tooth pinion LINK

    16 tooth pinion LINK

    Ok, Is the 16t a 5mm bore? So, I'm running on thick grass, up, down, and around this hill. So, which gearing would be the best, besides the stock 14t? I want just a little more speed. Thanks.

    that line of pinions wont work... check out the .8 mod line from RRP :

    Its the small bore of the previous pinion that makes it incomparable.
    To SUMMIT up, its my coolest RC.

    I have the 14.4 Dewalt. My son bashes on the track and dirt/gravel with a 19 tooth pinion. Grass, like a park or football field we drop to an 18 tooth. The 19 tooth ran a little warmer than I liked. He bashes with original Trenchers. Your Trencher X tires are a little shorter so the 19 will probably be fine.

    JMHO, but just like others have stated here and elsewhere, keep your eye on temps.

    BTW, looks like a fun place to let her rip
