What pinion gear should I use on the Tekno ET410.2?

It depends on your motor and the track. Racers in the 1/10 4WD truck class run a 16–25 tooth pinion in most setups, usually on a 81T spur for a final drive ratio near 10.93. Hotter motors (lower turns, higher Kv) take a smaller pinion; tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the ET410.2 selected.

What is the internal ratio (transmission ratio) of the Tekno ET410.2?

The ET410.2 has an internal ratio of 4:1. Final drive ratio = spur ÷ pinion × 4. With the stock 53T spur, a 14T pinion gives an FDR of 15.14 and a 27T gives 7.85.

How many teeth is the stock spur gear on the Tekno ET410.2?

53 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 Tekno ET410.2 come with?

Out of the box the ET410.2 runs 450 cst front, 450 cst rear (Tekno oil), on 5 x 1.1mm (#6705E) front, 5 x 1.2mm (#6705E) 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 Tekno ET410.2 come with?

The kit springs are Green 5.25 (#TKR7042) front, Red (#7247) - stiffest rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.

What diff fluid does the Tekno ET410.2 come with?

The kit diff fluid is 30,000 cst front, 30,000 cst center, 15,000 cst rear. Thicker front adds steering on power; thicker center sends more drive rearward; thicker rear stabilizes the car under throttle.
