Truggy combos?

Then maybe change the spur, what vehicle do you have ? Kyosho ST ? There is some 50 or 52 T spur .
Its better to have a big spur because you can use a big pinion for same ratio. And big pinion give mechanical energy to the spur with less loses than small pinions, the noise is also well reduced (motor temp too !!!!!) ;) and if the shimming is correct, the pinion will last a human life ^^
