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
Flux MMH-4000kV brushless with the Flux EMH-3S ESC; manual rates the system for 2-3 cell LiPo (7.4-11.1V).
- Taller gearing than the brushed Sport 3 (66T spur, 32T pinion).
- Stock rubber on this SKU is the wide Falken Azenis slick pair (31mm front / 34mm rear on 48mm BBS wheels), NOT the brushed car's 26mm Spec-Grip; HPI publishes no outside diameter for either, so the OD is a class figure.
