So, I have a mini Slash and a Ken Block. In the Slash manual it says that the stock pinion size is 31T and the high-speed pinion size is 28T. In the Ken Block manual it says the stock is 28T and the high-speed is 31T. Which is right??? Or would it differ from truck (off road) to car (on road)?
I'm also a little confused about which size pinion to install while using 2 NiMh batteries in series or while using LiPo.
