It depends on your motor and the track. In the 1/8 4WD truck class, racers gear by final drive ratio: 1800–2300 kV near 13.97. On the Talion's stock 50T spur that is about 15T for 1800–2300 kV. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the Talion selected.
What is the internal ratio (transmission ratio) of the ARRMA Talion?
The Talion has an internal ratio of 4.3:1. Final drive ratio = spur ÷ pinion × 4.3. With the stock 50T spur, a 12T pinion gives an FDR of 17.92 and a 18T gives 11.94.
How many teeth is the stock spur gear on the ARRMA Talion?
50 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
