It depends on your motor and the track. In the 1/12 2WD gp class, racers gear by final drive ratio: 6T and below near 3.67, 7.5–8.5T near 2.59, 13.5T near 1.72, 17.5T near 1.44. On the ECLIPSE 3's stock 76T spur that is about 21T for 6T and below, 29T for 7.5–8.5T, 44T for 13.5T, 53T 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 ECLIPSE 3 selected.
What is the internal ratio (transmission ratio) of the Schumacher ECLIPSE 3?
The ECLIPSE 3 has an internal ratio of 1:1. Final drive ratio = spur ÷ pinion × 1. With the stock 76T spur, a 22T pinion gives an FDR of 3.45 and a 56T gives 1.36.
How many teeth is the stock spur gear on the Schumacher ECLIPSE 3?
76 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
