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. The maker advertises 70 mph, which is their own claim on their own conditions.
How these numbers were settled
Stock pinion is 20T, which is what Arrma's printed 7.125 final drive is computed against (50/20 x 2.85).
- A 26T optional speed pinion (ARA311009) also ships in the box and Arrma's own bullet says the 70+ mph figure needs it; both pinions appear in the Vendetta exploded view.
- Tire is the dBoots Elevens 35/085 2.4 (ARA550093) named in that exploded view: in Arrma's dBoots designation the second number is the tire outside diameter in mm, which their Hoons 42/100 page confirms by printing Outer Diameter 100mm for a 42mm-wide tire.
