It depends on your motor and the track. In the 1/10 FWD touring/gt class, racers gear by final drive ratio: 17.5T near 4.51. On the EXECUTE MF1's stock 86T spur that is about 36T for 17.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the EXECUTE MF1 selected.
What is the internal ratio (transmission ratio) of the Xpress EXECUTE MF1?
The EXECUTE MF1 has an internal ratio of 1.9:1. Final drive ratio = spur ÷ pinion × 1.9. With the stock 86T spur, a 36T pinion gives an FDR of 4.54 and a 47T gives 3.48.
How many teeth is the stock spur gear on the Xpress EXECUTE MF1?
86 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
