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 published means it exists but no source we could find prints it.
How these numbers were settled
Distinct model from the UTB18 Capra 4WD already in the catalog (four-wheel steering, spool diffs, Mickey Thompson tires).
- Brushed 37T 380 motor, so no Kv.
- Tire OD is NOT published for this variant and is inferred; see evidence.
- Do not trust Axial's separately printed 'Internal Gear Ratio 10.2:1' for this platform, it does not reconcile with the 44.88 total.
- Portal axles.
- Portal gear set AXI212001 is 26T/15T = 1.73333:1 (Axial manual parts list).
