It depends on your motor and the track. A hotter motor (lower turns, higher KV) takes a smaller pinion; a tight track wants a lower gear than an open one. Start near the middle of the pinions the NASCAR 1/12 (Road) shipped with, run a few minutes, and check motor temperature before going up a tooth. The So Dialed Pinion Recommender gives a starting pinion for your motor where we have class data.
What is the internal ratio (transmission ratio) of the Team Losi NASCAR 1/12 (Road)?
The NASCAR 1/12 (Road) has an internal ratio of 2.5:1. Final drive ratio = spur ÷ pinion × 2.5. With the stock 59T spur, a 20T pinion gives an FDR of 7.38 and a 50T gives 2.95.
How many teeth is the stock spur gear on the Team Losi NASCAR 1/12 (Road)?
59 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
