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 (3.2 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
The manual's parts list names the motor as '98060 - 54 Turn RC540 Brushed Motor w/ 14T Pinion Gear', the pinion again as '18122 - 14T Motor Gear for Everest 10 (0.6 module)', and the spur as '18121 - Spur Gear (87T)(48 pitch)', a spur reduction of 87/14 = 6.21.
- The same list gives the transmission gear set as 18129 (20T, 28T and 53T gears) and each axle as a 38T main gear (18009) driven by a 13T differential pinion (02030), 38/13 = 2.92.
- The transmission and axle ratio and the final drive are still left blank, because the centre-unit exploded view does not show which transmission gear drives which.
- Brushed 54T 540 motor, so no KV.
- The manual lists the Hexfly HX-1040-CRAWLER ESC, which Hobbywing rates for 2-3S LiPo.
- The 126mm is Redcat's 'Wheel Diameter', but a 1/10 crawler wheel cannot be 126mm across, so it is the mounted tire.
- Redcat's 90mm ground clearance figure cannot be squared with it and is not used.
