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 Mi10's stock 85T spur that is about 21T for 6T and below, 34T for 13.5T, 34T for 17.5T, 42T 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 Mi10 selected.
What is the internal ratio (transmission ratio) of the Schumacher Mi10?
The Mi10 has an internal ratio of 1.818:1. Final drive ratio = spur ÷ pinion × 1.818. With the stock 85T spur, a 20T pinion gives an FDR of 7.73 and a 52T gives 2.97.
How many teeth is the stock spur gear on the Schumacher Mi10?
85 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.

What shock oil does the Schumacher Mi10 come with?
Out of the box the Mi10 runs 450 cst front, 450 cst rear (CORE oil), on 4 x 1mm (#U7537) front, 4 x 1mm (#U7537) rear pistons. That is the kit setup; you will need to adjust it for your track conditions. The RC Setup App can help dial it in.
What springs does the Schumacher Mi10 come with?
The kit springs are 2.6 N/mm Black (#CR844) front, 2.8 N/mm Yellow (#CR846) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
