Kyosho Lazer ZX6.6

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

Electric 1/10 4WD kit; motor, battery and tires are sold separately, so KV and cell rating do not apply and the tire size is left blank.

• Kyosho's Technical Data gives 'Gear Ratio 10.26:1 (Spur 78T/ Pinion19T)' and the kit contents include the 19T pinion.
• The ratio after the spur works out to 10.26 x 19/78 = 2.50.
