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.
Gearing parts

| Pinion | 16T | 48P | Not published | ECX212019 (opens in a new tab) |
| Spur | 60T | 48P | Not applicable | ECX212018 (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 (2 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
Horizon's spec table prints a 16T pinion, a 60T 48P spur and a 4.3in (110mm) outer diameter for the 1.9 Falken Wildpeak tire.
- The manual's parts list names the 1/18 Temper's 60T spur, 14T axle pinion and 38T spool, and Horizon sells one transmission gear set (ECX212029) for both the Barrage and the Temper; the Temper's page prints a 7.55 internal gear ratio, which is carried over, and the total is worked out as 60/16 x 7.55 = 28.31.
- The manual gives the 60A ESC a 6.0 to 8.4V input with a LiPo setting, which is a 2S ceiling.
- The motor is a Tazer 370 brushed, which has no KV rating.
