Im kinda new to the hobby got myself a electric duratrax evader st and i heard that if you change the pinion or spur gear that it will make your truck go faster. Any ideas of what gear to get. Im not sure what to get and would it be expensive?

Thanks

Well I run a 21 and a 81 48pitch with a stock motor in my MF2 and it run really good.
Gears can be expensive but there ok.
$10-15 will get you a new spur and pinion.
