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. 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

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

The Utron SE runs the same Stealth XF transmission as the Enduro SE Sendero: the manual names an 18T pinion (part 1336) on a 45T/27T running gear, a 50T slipper spur, a 20T top shaft, a 28T idler and 52T outputs, which works out to 12.04:1, and the press release prints 'Internal Gear Ratio 12:1'.

The product page prints 'varies' instead, which reflects the optional overdrive gears rather than the truck as delivered, since the transmission ships set to 1:1.
The 45T running gear is the gear the pinion meshes with, so it is shown here as the spur.
The rear axle uses a 30T ring gear on an 8T pinion; the Camburg IFS2 front end uses an 8T pinion and the same 30T ring gear part (42335), as the Zuul IFS2 manual shows, and the Utron manual offers the 30T/8T Factory Team set (42336) for it.
That gives 3.75:1 at both ends, a transmission and axle ratio of 18.06 after the 45T gear, and 45.14:1 from motor to wheel.
The 1.9 x 4.19 in PinSeeker tire (106 mm) is printed in the manual and on the tire's own part page (42349).
Associated lists the motor only as brushed, so KV does not apply.
The ESC is not named; the spec page asks for a 6-cell NiMH or a 2S or 3S LiPo pack with a T-type connector, so 3S is shown as the limit.
