Kyosho TF7.7

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.

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

Electric 1/10 touring car kit; the 540 motor, ESC, pinion gears, tires and wheels are required and not included, so the pinion, KV and cell rating do not apply and the tire size is left blank.

• Kyosho's Technical Data gives 'Gear Ratio 1.90:1 (2nd)', which matches the 38T diff pulleys and 20T front drive pulley in the spare-parts list.
• The spare-parts list gives a 64 pitch 116T spur (TF228-116).
