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 XV-02RS Pro 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 Tamiya XV-02RS Pro?
The XV-02RS Pro has an internal ratio of 2.6:1. Final drive ratio = spur ÷ pinion × 2.6. With the stock 70T spur, a 15T pinion gives an FDR of 12.13 and a 35T gives 5.20.
How many teeth is the stock spur gear on the Tamiya XV-02RS Pro?
70 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
