    Rustler gear ratio

    Hi i am converting my bandit to a rustler and i am trying to find a better gear ratio i am using a Team Orion Method R 19x2 motor driving hpi 2.2 mesh wheels and i am running proline road hawgs and i was wondering what the best gear ratio would be for it to give it higher top speed , also my friend is running a tamiya tz in a traxxas rustler and his is realy quick and he is running a 23 tooth pinion and the stock spur and my motor has the same rpm so should i just use the same ratio ?

    RE: Rustler gear ratio

    No, don't use a 23t pinion with a 19 turn motor, at least not without testing it. What I mean is for a Rustler, using the stock spur or close to its size (84-90t), you usually use a pinion that is 2 teeth lower than the turn count of the motor. Again, usually. The rpm does not matter as much as motor torque when it comes to gearing it because it can cause heat problems. Try a 17 tooth pinion with your 19T motor, and if it runs cool enough (less than 130-160'F or so) or to where you can still keep your finger on the motor for more than a couple odd seconds after running it several minutes, then try a pinion tooth higher.

    Those 2.2" Dirt Hawgz are slightly large and heavier than most 2.2" on-road tires, so you want to keep the load on the motor less by using a small pinion.

    Whoops!! I misread it. I've used those tires too. Yeah in that case you want to try a 20t or so pinion and go up from there.
