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. The maker advertises 50 mph, which is their own claim on their own conditions.
Gearing parts
| Component | Teeth | Pitch | Bore | Part number |
|---|---|---|---|---|
| Fitted at the factory | ||||
| Pinion | 16T | Mod 0.8 | 5 mm | ARA310999 (opens in a new tab) |
| Spur | 57T | Mod 0.8 | Not applicable | ARA311167 (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 223S successor to the Typhon 3S BLX V3 buggy, with a Spektrum Firma 3660 3100Kv motor and the Spektrum SLT 80A 2-in-1 ESC and receiver rated for 2S or 3S LiPo.
- Arrma prints no gear ratios for this SKU.
- The 16T pinion (the V3 ran 15T) and the 57T centre diff spur come from Horizon's standard-parts list.
- Horizon's standard-parts list for this SKU names the 37T 1.35M front and rear diff sets and the 13T 1.35M input gears (37/13 = 2.846), the same pair Arrma prints as a 2.85 transmission and axle ratio on the Infraction 223S and the 3S V3 trucks, so 2.85 is used here.
- Final drive is 57/16 x 2.85 = 10.15.
- The stock tire is the dBoots 2-HO (ARA550118), whose page prints an overall diameter of 4.6 in (117mm).
- Arrma quotes 50+ mph on 3S, and stock gearing computes to about 46 mph at 3.7V per cell, 53 mph fully charged.
