## What is the best gearing for a Traxxas Slash 4×4?

In fact, the popular gearing for a Slash 4×4 with a Sidewinder 8th system is a 20T pinion gear and a 50T spur gear. This gives you plenty of speed, but still keeps the temps down overall.

## How do you calculate RC transmission ratio?

For shaft cars, the transmission ratio is calculated by dividing the number of teeth on the differential’s ring gear by the number of teeth on the bevel pinion that it mates with.

How do you calculate gear to transmission ratio?

The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).

### What is transmission ratio?

The transmission ratio is defined as the ratio of the angular velocities or frequencies of rotation of the components. This usually refers to the ratio of the angular velocity of the driving component to the angular velocity of the driven component: u = ω1/ω2.

### Which pinion gear is faster?

Gearing changes are mainly done to make a vehicle faster, or on the scale/crawling side, crawl better. A bigger pinion or smaller spur gear makes the vehicle have more top speed, at a decrease in acceleration. It’s most likely that gearing up will make everything run a bit hotter, and shorten run times.

What’s the fastest RC motor?

Traxxas XO-1
“The Traxxas XO-1 is the fastest RC car, full stop. The largest brushless motor on offer propels the car from 1 to 60 in 2.5 seconds. Not only is this car stylish, but it also reaches speeds over 100 miles per hour.”
