Infinity IF11-II

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.

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

1/10 Formula 1 kit; the manual lists the motor, 64 pitch pinion, battery, tires and wheels as not included, so the pinion, KV and cell rating do not apply and the tire size is left blank. The 92T 64 pitch spur (F081) is built onto the rear axle differential, so there is no reduction after it and the ratio after the spur is 1.

Every figure on this page traces to one of these. Where they disagreed, the note above says which was used and why.
