Vanquish Products VS4-10 Origin Classic

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

Vanquish publishes the whole set: 'Axle Ratio 3.75:1, Pinion 15T 32P, Spur 52T 32P, Overall Front Ratio 38.3:1, Overall Rear Ratio 40.9:1, Final Overdrive 6.5%'.

• As on the Element Stealth X, the VFD transfer case runs different front and rear ratios, so there is no single ratio after the spur; the rear is used as the defensible one and the front is 38.3:1 (the front turns faster: the 6.5% overdrive, 40.9 / 38.3 = 1.068).
• The 11.8 ratio after the spur is the rear reduction derived from the published total and tooth counts, 40.9 x 15 / 52 = 11.80, and (52/15) x 11.8 = 40.91, within 0.02%.
• Cross-check: Vanquish's Straight Axle Builders Kit, a different 13T/56T combination on the same VFD and 3.75 axles, where 50.8 x 13 / 56 = 11.79.
• Unassembled kit: no motor, ESC, wheels or tires, so KV and cell count are blank.
• Tire diameter is Vanquish's build requirement for the kit, '1.9x4.65" TIRES', i.e. 4.65 in = 118mm outside diameter on a 1.9 rim, not the rim size.
