I hope you guys keep the moters a bit down: I'm not planning to put any wild stuff into my vintage buggies.
I'm using 23-30t motors for old cars (like 834B) to protect tranny. But in case of RC10&10T/Stealth, YZ870C and so on, I use much hotter motor like 13t, 15t. Yatabe's vintage class is competed by control motors. 2wd cars and 4wd cars run at once but 2wd must use Yokomo Pro Stock 27T and 4wd is 30T of same. So, you have to choose the pinion very seriously.
I have made account for Tanaka and invited him to here. He's perplexed little bit but promised to post something. Please wait for his reaction.
Well, do you know who he is?
