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 published means it exists but no source we could find prints it. The top speed is kinematic: an ideal no-load RPM with no slip and no loss under load, so a real car is slower. The maker advertises 40 mph, which is their own claim on their own conditions.
Gearing parts
| Component | Teeth | Pitch | Bore | Part number |
|---|---|---|---|---|
| Fitted at the factory | ||||
| Pinion | 15T | Mod 1 | 5 mm | LOSA3575 (opens in a new tab) |
| Spur | 46T | Mod 1 | Not applicable | TLR342021 (opens in a new tab)Team Losi Racing |
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
This is the ready-to-run truggy with Spektrum sensored power, separate from the TLR 8IGHT-XTE race kit.
- The manual lists the stock pinion as 15T MOD1 with a 5mm shaft (LOSA3575), and its parts list names a 46T center diff spur (TLR342021).
- Losi's spec table prints the same 15T and 46T with an internal ratio of 4.30 and a gear ratio of 13.19, and 46/15 x 4.30 is 13.19.
- The tire size is an estimate: the stock Pro-Line Convict M3 truggy tire (PRO907202) is listed at 5.52 in (140 mm) tall on its Horizon page, which Losi does not state as the diameter.
- On a full 4S charge that gearing gives about 47 mph in theory, which fits the 40+ mph claim.
- The manual lists center diff fluid as 12k and front and rear as '10k / 6k' without saying which is which, so the front and rear diff fluids are left blank.
- The body comes clear and needs paint.
