It depends on your motor and the track. A hotter motor (lower turns, higher Kv) takes a smaller pinion; a tight track wants a lower gear than an open one. Start near the middle of the pinions the RC28F shipped with, run a few minutes, and check motor temperature before going up a tooth. The So Dialed Pinion Recommender gives a starting pinion for your motor where we have class data.
What is the internal ratio (transmission ratio) of the Team Associated RC28F?
The RC28F has an internal ratio of 1:1. Final drive ratio = spur ÷ pinion × 1. With the stock 53T spur, a 6T pinion gives an FDR of 8.83 and a 14T gives 3.79.
How many teeth is the stock spur gear on the Team Associated RC28F?
53 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
Kit setup
Kit shock setup. Part numbers link to AMain.
What shock oil does the Team Associated RC28F come with?
Out of the box the RC28F runs 30,000 side tubes (Team Associated oil). 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 Team Associated RC28F come with?
The kit springs are Hard Red (#21651) front, Soft White (#21652) center. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
