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.
Gearing parts

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
Element's spec table prints 'Internal Gear Ratio: varies' because the Stealth X gearbox turns the front and rear axles at different speeds, so the transmission and axle ratio and the final drive are left blank.
- The manual names an 18T 48P pinion (#1336) and an 87T 48P spur (#9654), a fixed 20T-28T-52T front train with the 27T-53T rear pair fitted (5.7% front overdrive), and 30T/8T ring and pinion gears in both axles.
- Worked out from those tooth counts, the total reduction is about 47.1:1 at the front and 49.8:1 at the rear; the included 26T-54T rear pair (11.83% overdrive) gives about 52.7:1 at the rear.
- The manual fits General Grabber A/T X tires (#42275), and Element's page for that part gives them as 1.9 in x 4.19 in diameter.
- The 16-turn 5-slot motor is brushed, so KV does not apply; the manual rates the FlySky ESC/receiver for 2S-3S LiPo.
