What pinion gear should I use on the Team Associated RC10 T4 Family?

It depends on your motor and the track. In the 1/10 2WD truck class, racers gear by final drive ratio: 7.5–8.5T near 10.14, 13.5T near 8.27. On the RC10 T4 Family's stock 87T spur that is about 22T for 7.5–8.5T, 27T for 13.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the RC10 T4 Family selected.

What is the internal ratio (transmission ratio) of the Team Associated RC10 T4 Family?

The RC10 T4 Family has an internal ratio of 2.6:1. Final drive ratio = spur ÷ pinion × 2.6. With the stock 87T spur, a 16T pinion gives an FDR of 14.14 and a 30T gives 7.54.

How many teeth is the stock spur gear on the Team Associated RC10 T4 Family?

87 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
