On the RC10 T5M's stock 84T spur that is about 22T for 7.5–8.5T, 26T for 13.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the RC10 T5M selected.
The RC10 T5M has an internal ratio of 2.6:1. Final drive ratio = spur ÷ pinion × 2.6. With the stock 84T spur, a 16T pinion gives an FDR of 13.65 and a 30T gives 7.28.
84 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.

Out of the box the RC10 T5M runs 35 wt front, 35 wt rear (Team Associated oil), on 2 x 1.6mm (#91308) front, 2 x 1.7mm (#91308) 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.
The kit springs are 3.6lb Blue (#91330) front, 2.1lb White (#91337) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
