Traxxas TRX-4 Detailed Review

Key Features

There are a few things that set the Traxxas TRX-4 Crawler apart from its competitors. We will discuss them in detail to see just how superior they make the machine.

Lockable Front And Rear Differentials

The Traxxas TRX-4 Crawler comes with remotely lockable front and rear differentials. You can lock and unlock both the differentials right from your transmitter to give you flexibility as well as good performance.

You can choose to unlock both the diffs when cruising on level track and for better handling when turning at high speeds. When you encounter a rugged trail, you can either lock both the diffs or just the front diff for ultimate grip on the front tires which aids in crawling over rocks.

2-speed transmission​​​​

The 2-speed transmission gives you the freedom to run the car as you want. The fact that this feature comes with the remotely lockable diffs makes it all the more worthwhile.

You can switch between high and low-speed modes with the combination of locked or unlocked diffs for maximum freedom and efficiency. The best part about the 2-speed transmission is that there is little slop when the vehicle is in gear.

This makes it easier to go up and down terrains.

Portal Axles

The portal axles that come with the Traxxas TRX-4 Crawler give the vehicle great ground clearance. This is especially useful when you want to climb over big rocks and boulders.

To put things in perspective, you would need tires that are at least 1 inch taller than Traxxas TRX-4 Crawler’s to get the same clearance and ease with a straight axle.

Ease Of Use

The Traxxas TRX-4 Crawler is arguably one of the easiest crawlers to use. That’s what they had advertised when the product was launched, and that’s what the customers say when they take it for a spin.

The car comes assembled, so that’s one less thing to worry, and it’s RTR out of the box. All you have to do is put in the battery (which you have to buy separately) and get going. The sturdy frame and waterproof design make it easy to use in any terrain and topography.

Efficiency while Running

With features like portal axels, 2-speed transmission and remotely lockable front and rear diffs, the performance of Traxxas TRX-4 Crawler is unmatched.

Whatever the terrain is, you have all the features to get your RC out of it with ease and grace. Going uphill and over rocks? Lock the diffs and use the low-speed mode to make hairpin turns and move through challenging tracks.

Climbing boulders? The portal axel gives you enough ground clearance to change the impossible into a challenge and adventure.

Build Quality Of The Traxxas TRX-4

When you open the box, you are swept off your feet by the attractive design. The attention to detail with a spare tire on the back and rear view mirrors is immaculate.

The black painted windows are a slight hiccup, but not a deal breaker by any means. While being attractive, it is also sturdy. You can use it on rough terrains without having to worry about the body.

The waterproof electrical equipment and body make it an all-terrain crawler.
