It depends on your motor and the track. In the 1/8 4WD buggy class, racers gear by final drive ratio: 1800–2300 kV near 10.06. On the EB48 2.2's stock 44T 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 EB48 2.2 selected.
What is the internal ratio (transmission ratio) of the Tekno EB48 2.2?
The EB48 2.2 has an internal ratio of 3.333:1. Final drive ratio = spur ÷ pinion × 3.333. With the stock 44T spur, a 12T pinion gives an FDR of 12.22 and a 19T gives 7.72.
How many teeth is the stock spur gear on the Tekno EB48 2.2?
