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. Not published means it exists but no source we could find prints it.
Gearing parts
| Component | Teeth | Pitch | Bore | Part number |
|---|---|---|---|---|
| Fitted at the factory | ||||
| Pinion | 13T | 32P | 3.175 mm | 150138 (opens in a new tab) |
| Spur | 48T | 32P | Not applicable | 150137 (opens in a new tab) |
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
The first-generation brushed Quantum XT with an MM-550 15T motor.
- The quick start guide's parts list names a 13T 32DP pinion (3.175mm shaft) and a 48T 32DP spur.
- The quick start guide's parts list names the 40T/13T differential bevel gear set and no other reduction after the spur, so the after-spur ratio is worked out as 40/13 = 3.08; the train is read from the parts list, as no gearing diagram is printed.
- The total is 48/13 x 3.08 = 11.36.
- The kit's standard parts list names the Tredz Accelerator tire, 120x70mm on its part page.
- The MSC-30BR-WP ESC manual rates it for 2 to 3S LiPo, but 3S only with motors of 18T or milder, so with the stock 15T motor the ceiling is 2S.
- The motor is brushed and has no KV rating.
