Robinson Racing Mini 8IGHT .5 Mod Hardened Steel Mini Pinion (2mm Bore) (12T)
I installed this 12t pinion on a Mini-b with a Hobbywing 2030 7,800kv and 5200kv motor. On both motors this pinion gear was so out of balance, it shook the car. On a closer inspection, the bore of the pinion gear is oversized compared to the 18t pinion that came with the car and the 15t Losi pinion that I bought. I wanted to lower the temps on the motor but I'll stay with the 15t and buy a new motor when it burns up.
