Infinity IF18

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. 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. Not published means it exists but no source we could find prints it.

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.

How these numbers were settled

Nitro 1/8 on-road car with a two-speed transmission; the .21 engine and tires are not included.

• The manual supplies 0.8 module gears: a 19T first and 24T second pinion with a 62T first and 58T second spur.
• Second gear, 24T on 58T, is stored as the fitted set.
• The belt and pulley reduction after the spur is not printed, so it and the total are left blank.
