Kyosho Ultima RB7

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.

How these numbers were settled

Electric 1/10 2WD kit.

• Kyosho's Technical Data gives '1st Deceleration: Spur 76T / Pinion Gear sold separately' and '2nd Deceleration: 2.6:1', so the pinion does not apply and the total depends on the pinion fitted.
• Motor, battery and tires are also sold separately, so KV and cell rating do not apply and the tire size is left blank.
