Pinion gear for B4
I just got my self a B4 in a trade with my friend. Its brand new in a box and at the moment I m in the process of building it. I really don't know anything about this kit. My q is what type of pinion should I use with it, and how many teeth? I ll be putting my 5.5T BL motor in it. Also if you have any advice during building, pls do so.
