Pinion question..
I just built my first onroad a TB03 for bashing in my culdasac. My question is with a 4.5T brushless motor on my Mamba Max Pro ESC with Thunder power 40c 2s 5000 Lipos running on the stock spur (I believe 64t) what pinion should I run to stay nice and cool and run in the 55-60mph range?
