Kyosho Inferno NEO 3.0

Stock is as the vehicle ships. Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart. Derived is worked out from gear tooth counts the maker publishes rather than printed as a ratio; the notes below say how. Not applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor.

In our catalog, half of 1/8 buggies run between 10.2:1 and 12.0:1 on stock gearing; this one is 11.7:1. What's a normal final drive for your RC?

Gearing parts

Tooth counts are the ones in the specifications above. Pitch is given as metric module (Mod 1, Mod 0.8) or diametral pitch (32P, 48P). They are different standards and are not interchangeable, even where the numbers look close. Bore is the pinion’s hole, listed separately from the motor shaft. Linked part numbers go to the maker's or official distributor's page for that part.

How these numbers were settled

Ready-to-run nitro version of the NEO 3.0 with a KE21SP engine, so KV and cell rating do not apply.

• Kyosho's Technical Data prints 'Gear Ratio 11.56：1', but the spare parts list names the same gears as the NEO 4.0: a 13T one-piece clutch bell (97035LW-13), the IF148B 46T spur, and the IF106 43T bevel gear with a 13T drive bevel (IF21).
• Those tooth counts give 46/13 x 43/13 = 11.70, the figure Kyosho prints for the NEO 4.0 and the MP10 readyset with the same parts, so 11.70 is shown here and the ratio after the spur is 3.308.
• No combination of the listed gears gives 11.56.
• The Technical Data gives 'Tire (F/R) φ116×44mm／φ116×44mm'.
• The maintenance manual gives a range of diff oils (#3000 to 5000) rather than one grade.
• Colour types T1 to T6 (T5 and T6 from November 2023) share the same Technical Data.
