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. 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 | 9T | Mod 1 | 3 mm | ECX232028 (opens in a new tab) |
| Spur | 45T | Mod 1 | Not applicable | ECX232019 (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 earlier 4WD brushed Ruckus sold with a 7-cell NiMH pack.
- Horizon's spec table prints a 9T pinion, a 45T Mod 1 spur and a 5.3in (134.6mm) outer tire diameter.
- No diff tooth counts or gear ratio are published, so the ratios are left blank.
- The 4WD manual gives the ESC as 6.0 to 8.4V with a LiPo setting, which is a 2S ceiling.
- The motor is brushed and has no KV rating.
