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.

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
Horizon's spec table prints a 22T pinion, a 60T 48P spur and a 4.3in (108mm) outer tire diameter.
- The manual's parts list names the ECX212029 transmission gear set, the ECX212010 14T axle pinion and the ECX212009 38T spool, the parts Horizon sells for the first Temper, whose page prints a 7.55 internal gear ratio; that ratio is carried over and the total is worked out as 60/22 x 7.55 = 20.59.
- The motor is a Tazer 32T 380 brushed, which has no KV rating.
- The manual gives no voltage rating for the crawler ESC and the truck ships with a 7.2V NiMH pack, so the cell count is left blank.
