It depends on your motor and the track. In the 1/10 4WD touring/gt class, racers gear by final drive ratio: 6T and below near 7.34, 13.5T near 4.51, 17.5T near 4.51, 21.5T and up near 3.65. On the EXECUTE XQ3S's stock 110T spur that is about 28T for 6T and below, 46T for 13.5T, 46T for 17.5T, 57T for 21.5T and up. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the EXECUTE XQ3S selected.
What is the internal ratio (transmission ratio) of the Xpress EXECUTE XQ3S?
The EXECUTE XQ3S has an internal ratio of 1.9:1. Final drive ratio = spur ÷ pinion × 1.9. With the stock 110T spur, a 20T pinion gives an FDR of 10.45 and a 52T gives 4.02.
How many teeth is the stock spur gear on the Xpress EXECUTE XQ3S?
110 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
