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

Brushed Firebolt 15T 540; SC-3SWP2 ESC is 2S/3S capable but its own motor-turn limits restrict a 15T motor to 2S. Internal 3.07 is HPI's own figure; the physical stage is the 40T/13T diff bevel pair (3.077).

Sources

Every figure on this page traces to one of these. Where they disagreed, the note above says which was used and why.
