If I did the calculations right on the calculator. Getting closest to 0. Rollout ration 4.5.<div></div><div>64T Spur</div><div>22T Pinion</div><div>2.4 Transmission Ration</div><div>2.5" Tire Diameter(I use HPI T-Drifts on HPI 26mm Rims.)</div><div></div><div>I should be using a Tamiya 10T Pinion. It's even on the manuel as a suggestion to use 10T-15T on the Novak Ballistic 3S 8.5T Brushless System. Hopefully I got this right and I wont burn anything out or come up with less power. Let me know you thoughts guys.

Although I looked at 10T Tamiya Pinion gear and it looked to small. WHat would you guys recommend?</div>
