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. The top speed is kinematic: an ideal no-load RPM with no slip and no loss under load, so a real car is slower.
Gearing parts
| Component | Teeth | Pitch | Bore | Part number |
|---|---|---|---|---|
| Fitted at the factory | ||||
| Pinion | 16T | Mod 1 | Not published | RER19572 (opens in a new tab) |
| Spur | 46T | Mod 1 | Not applicable | RER32484 (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 (5 mm on the stock motor). Linked part numbers go to the maker's or official distributor's page for that part.
How these numbers were settled
The manual's parts list names an RER19572 '16 tooth Steel Pinion Gear (Mod1)', an RER32484 'Spur Gear 46T (Mod 1)' on the centre diff, and in each axle an RER32518 'Diff Pinion (14T)' against an RER32505 'Differential Ring Gear (41T)'.
- The list also includes an RER32509 'Idler Gear (15T)'.
- The exploded view places that single idler on the motor mount between the pinion and the spur, which does not change the ratio, so the reduction is read as 46/16 = 2.875 at the spur and 41/14 = 2.93 at each axle, 8.42 in total; the idler's position is read from the drawing, not stated in words.
- Redcat's specification table gives a 1950KV 3670 motor and a Hobbywing MAX10 SCT 120A ESC, and the product copy says it handles 2S to 4S LiPo.
- The 131mm 'Wheel Diameter' is the tire: the product copy gives the open lug tires as 5.1in x 2.32in, and the table's 59mm wheel width is the same 2.32in.
