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. The top speed is kinematic: an ideal no-load RPM with no slip and no loss under load, so a real car is slower.
How these numbers were settled
Belt-driven 4WD, a different chassis from the shaft-driven RS4 Sport 3.
- Flux Vektor 5900kV.
- HPI's own Flux insert states 6-7 cell NiMH or 2 cell LiPo and advises against 3S with this motor, hence 2 cells.
- The ratio after the spur is the belt stage (15T centre pulleys to 32T diff pulleys), inferred from part names rather than a printed ratio.
