    Rustler XL - 5 question

    If I wanted to make my rustler XL -5 a little faster than the stock gearing(19, 86) without overheating would a 19 pinion and 76 spur help increase speed while keeping temps lower than the included speed gearing traxxas gives you(28 pinion, 86 spur).

    That will make it faster, but that is a jump in gearing and will have a significant jump in temps. I'd recommend going to a 22-23 tooth pinion first.

    No matter what you do, it is always a good idea to check temps of your motor every 5 minutes or so for the first pack after changing anything in the drive train.
