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
| Component | Teeth | Pitch | Bore | Part number |
|---|---|---|---|---|
| Fitted at the factory | ||||
| Pinion | 13T | 32P | 3.175 mm | IRC00261 (opens in a new tab)Incision |
| Spur | 56T | 32P | Not applicable | IRC00411 (opens in a new tab)Incision |
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
Vanquish prints '3.75:1 Axle Gear Ratio, 13T Pinion, 56T Spur Gear, Overall Front Ratio (Standard 6.5% OD): 47.6:1, Overall Front Ratio (High 46% OD): 31.8:1, Overall Rear Ratio: 50.8:1'.
- The rear 50.8 is used because the VFD Twin's overdrive selector changes only the front.
- The ratio after the spur is 50.8 x 13 / 56 = 11.79.
- The kit includes 1.9 VXT tires on KMC KM233 wheels, printed as 'VXT 4.65" 1.9" tires', so 118.1mm.
- Motor, ESC and radio are left to the builder, so KV and cell count do not apply.
