Vanquish Products VS4-10 Builders Kit - Straight Axle

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. Derived is worked out from gear tooth counts the maker publishes rather than printed as a ratio; the notes below say how. Not applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor.

Gearing parts

Tooth counts are the ones in the specifications above. Pitch is given as metric module (Mod 1, Mod 0.8) or diametral pitch (32P, 48P). They are different standards and are not interchangeable, even where the numbers look close. Bore is the pinion’s hole, listed separately from the motor shaft.

How these numbers were settled

Vanquish prints '3.75:1 Axle Gear Ratio, 13T Pinion, 56T Spur Gear, Overall Front Ratio: 47.6:1, Overall Rear Ratio: 50.8:1'.

• The VFD transfer case overdrives the front, so the rear total is used and the front is 47.6:1.
• The ratio after the spur is 50.8 x 13 / 56 = 11.79.
• Wheels, tires, body and electronics are not included, so tire size, KV and cell count do not apply.

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