7 Worst Traxxas Trx4 Problems And Fixes

The Traxxas TRX4 is a great RC car, but it does have its share of problems. One common issue is that the drivetrain can bind up, making it difficult to drive. This can be caused by several things, including incorrect gear mesh or a binding differential.

Another problem that can occur is that the shocks can leak oil, resulting in a poor ride quality. Finally, the battery compartment can be too small for some batteries, making it difficult to get a good fit.

Are you thinking about buying a Traxxas TRX4, but you’re not sure if it’s the right RC for you? If so, then this blog post is for you! We’ll go over some of the most common problems that people have with the TRX4, so that you can make an informed decision before purchasing.

One of the most common problems with the TRX4 is that it doesn’t handle bumps and rough terrain very well. The suspension is often too stiff, which can cause the truck to bounce around and skid out when going over bumps. This can be frustrating for drivers, especially if they’re trying to drive on a difficult trail.

Another problem that people often have with the TRX4 is that it doesn’t have a lot of power. This can be an issue when trying to climb hills or drive through mud and snow. The truck sometimes struggles to get moving, and it can be very frustrating for drivers who are used to more powerful RCs.

Finally, one of the biggest issues people have with the TRX4 is its price. At around $700, it’s one of the most expensive RC trucks on the market. For many people, this price tag is simply too high and they end up opting for a cheaper model.

If you’re considering buying a Traxxas TRX4, then these are some of the things you should keep in mind. It’s important to weigh all pros and cons before making your final decision.

Is the Traxxas Trx4 Waterproof?

The Traxxas TRX4 is not a waterproof RC car. However, it is water resistant and can handle being driven in wet conditions. The electronics are all sealed up tight so that they won’t be damaged by exposure to water.

However, if you drive the TRX4 through puddles or standing water, the motors will eventually overheat and shut down. So while the TRX4 can handle being driven in the rain, it’s not meant for driving through deep water.

How Fast Can a Trx-4 Go?

The Traxxas TRX-4 Scale and Trail Crawler is one of the most popular RC crawlers on the market. It’s a versatile rig that can tackle just about any terrain, and it’s fast enough to keep up with most other RC vehicles out there. But how fast is it, exactly?

To answer that question, we’ll need to take a look at the TRX-4’s motor and gearing. The stock motor is a 540-size brushed motor that produces 12T of torque. When paired with the included 32-pitch pinion gear, this setup is capable of reaching speeds of up to 30mph.

Of course, you’re not limited to the stock motor and gearing. If you want to go even faster, you can install a bigger pinion gear or upgrade to a brushless motor. With some modifications, it’s possible to get the TRX-4 up to 50mph or more!

So there you have it – the Traxxas TRX-4 can reach pretty impressive speeds for an RC crawler. Whether you’re looking for a leisurely crawl through your backyard or an all-out speed run across open terrain, this rig can do it all.

How Do I Reset My Trx-4?

If you need to reset your TRX-4, here’s how: 1. Turn off the power to your TRX-4. 2. Remove the batteries from your TRX-4.

3. Press and hold the RESET button on your TRX-4 for 10 seconds. 4. While still holding the RESET button, reinstall the batteries in your TRX-4. 5. Release the RESET button after 10 seconds has elapsed.

How Long Does a Trx-4 Battery Last?

TRX-4 batteries are designed to last a long time. However, how long they actually last will depend on how you use them. If you use your TRX-4 regularly, you can expect the battery to last for several years.

However, if you only use it occasionally, the battery may only last for a few months.

Does Trx-4 Have Dig?

TRX-4 does have dig! In fact, it’s one of the many features that makes this crawler so special. With dig, you can control the Crawler’s front and rear axles independently, meaning you can make it turn tighter than ever before.

What’s more, TRX-4 is equipped with high-torque motors that give it plenty of power to climb over obstacles.

Are All Trx-4 Chassis the Same?

No, all TRX-4 chassis are not the same. There are four main types of TRX-4 chassis: the Trail Crawler, the Scale Crawler, the Rock Racer, and the Sport. Each type of TRX-4 chassis has its own unique set of features and benefits that make it well suited for a particular type of off-roading.

For example, the Trail Crawler is designed for maximum traction and articulation, making it ideal for crawling over obstacles. The Scale Crawler, on the other hand, is designed to provide a more realistic off-roading experience, with features like a removable hardtop and working headlights.

What Motor is in the Trx-4?

The Traxxas TRX-4 is powered by a 12-turn, 550-size motor. This is a brushed motor, meaning it uses carbon brushes to transfer power from the armature to the commutator. The windings on the armature are made of copper wire, and the magnets are permanent magnets.

The stator is made of steel laminations.

Traxxas Trx4 Weak Points

Traxxas TRX4 is one of the most popular off-road RC vehicles on the market. It’s a great choice for anyone looking to get into the hobby, or for experienced RC enthusiasts who want a capable and reliable crawler. However, like all RC vehicles, the TRX4 has its weak points.

Here are some things to keep in mind if you’re thinking about buying a TRX4: The suspension is one of the TRX4’s weakest points. The stock shocks are not very good, and they can cause the vehicle to bottom out on rough terrain.

This can be frustrating when you’re trying to crawl over obstacles. Luckily, there are many aftermarket shocks available that significantly improve the TRX4’s suspension performance. Another weak point of the TRX4 is its plastic body panels.

They are thin and easily damaged, especially when crawling over rocks or other sharp objects. Replacing them with aluminum or steel panels is a popular upgrade among TRX4 owners. Finally, the stock tires that come with the TRX4 are not very good in mud or sand.

They tend to slip and lose traction easily. Fortunately, there are many aftermarket tires available that perform much better in these conditions. Overall, the Traxxas TRX4 is a great RC vehicle.

However, it does have its weak points which should be considered before making a purchase.

Traxxas Trx4 Tips And Tricks

If you’re looking for tips and tricks to get the most out of your Traxxas TRX4, you’ve come to the right place. In this blog post, we’ll share some of our top tips to help you take your RC crawling game to the next level. One of the first things you’ll want to do is invest in a good set of tires.

The stock tires that come with the TRX4 are fine for general crawling, but they won’t provide the same level of traction and performance as a dedicated set of off-road tires. We recommend checking out Crawler Conceptz or Pro-Line for a great selection of both 2.2 and 1.9 sized tires. Another essential upgrade for serious crawlers is a set of steel beadlock wheels.

These will not only give your rig a more aggressive look, but they’ll also help keep your tires securely mounted on the wheels even when aired down for extra traction. Again, Crawler Conceptz and Pro-Line offer some great options here. When it comes time to hit the trails, one thing you’ll want to keep in mind is tire pressure.

For optimal performance, it’s best to air down your tires to around 10 psi or less. This will give you increased traction and allow your tires to conform better to obstacles. Just be sure not to go too low, as this can damage your rims and beadlock rings.

Finally, if you really want to take your TRX4’s crawling ability up a notch, consider adding weight over the rear axle with either lead weights or an aftermarket aluminum rear bumper/weight tray combo like those offered by SSDRC or CNC4x4 Designs . This will help improve rear grip on slippery surfaces and make climbing steep hills easier too.

Traxxas Trx4 Transmission Problems

If you own a Traxxas TRX4, chances are you’ve experienced some transmission problems. Whether it’s the gears slipping or the truck not moving at all, these issues can be frustrating. Here’s a look at some of the most common transmission problems and how to fix them.

One of the most common issues is the gears slipping. This can be caused by a few different things, but one of the most likely causes is worn out bearings. If your bearings are worn out, they’ll need to be replaced.

You can do this yourself or take it to a qualified mechanic. Another common issue is the truck not moving at all. This is usually caused by an issue with the drivetrain, such as a broken gear or stripped differential.

Again, you’ll either need to replace the broken part yourself or take it to a mechanic. If your TRX4 is having transmission problems, don’t despair! With a little bit of diagnosis and some elbow grease, you should be able to get your truck back on the road in no time flat!

Traxxas Trx4 Steering Problems

If you own a Traxxas TRX4, then you may have experienced steering problems at some point. There are a few different things that can cause this issue, so it’s important to troubleshoot and figure out what the root of the problem is. Here are some common causes of steering issues on the TRX4:

1. Worn Out Steering Components: Over time, the components in your steering system will wear out and need to be replaced. This includes things like the steering servo, linkage, and even tires. If you’ve noticed your steering isn’t as responsive as it used to be, or if there is more play in the system, then worn out parts is likely the culprit.

2. Dirty or Corroded Connections: Another common cause of steering issues is dirty or corroded connections. This can happen if you don’t clean and maintain your truck regularly. Check all of the connections in your steering system and make sure they are free of dirt and corrosion.

3. Incorrectly Adjusted Linkage: The final common cause of steering issues on the TRX4 is incorrect linkage adjustment. This is something that needs to be checked periodically, as it can easily become out of adjustment. Make sure all of the linkages in your system are properly adjusted and tightened down before driving your truck again.

Trx4 Weight Distribution

We all know that weight distribution is important for off-roading. A well-balanced vehicle is less likely to get stuck and can navigate obstacles more easily. The TRX4 by Traxxas takes this one step further with its innovative weight distribution system.

The heart of the TRX4’s weight distribution system is its aluminum chassis. This chassis has been specifically designed to evenly distribute weight across the entire vehicle. This gives the TRX4 a lower center of gravity and makes it more stable on uneven terrain.

In addition to the chassis, the TRX4 also features a number of other weight distribution innovations. For example, the battery tray is mounted low in the vehicle to help keep the center of gravity low. And, all four shocks are mounted inboard to improve stability and balance.

These design features work together to give the TRX4 exceptional off-road performance. Whether you’re crawling over rocks or blasting through whoops, you can be confident that your vehicle will handle whatever you throw at it!

Traxxas Trx4 Upgrades

If you’re looking to upgrade your Traxxas TRX4, there are a few things to consider. First, decide what you want to improve about your truck. Are you looking for more speed?

More power? Better handling? Once you know what you want to improve, research the different parts and upgrades that can help you achieve your goals.

There are a number of ways to increase the speed of your TRX4. One option is to install a brushless motor and ESC. This will give your truck more power and make it faster.

Another option is to install bigger tires. This will provide more traction and allow your truck to reach higher speeds. If you’re looking for better handling, there are a few options as well.

You can install shocks with adjustable spring rates, which will allow you to tune the suspension for different conditions. You can also add stiffer sway bars or lower the ride height of your truck for improved cornering ability. These are just a few of the many upgrades available for the Traxxas TRX4.

With so many options available, it’s easy to find an upgrade that will suit your needs and help you get the most out of your truck!

Trx4 Weights

The Trx4 by Traxxas is a 1/10th scale radio controlled crawler. It comes stock with a two-speed transmission, three-link suspension, metal gears, and locked differentials. The truck also has a low center of gravity which gives it great crawling abilities.

The Trx4 is equipped with LED lights in the front and rear that allow you to crawl in the dark. The truck comes with several different weight options that you can choose from. The lightest weight option is the 2WD version which weighs in at 4lbs 10oz.

The next heaviest option is the 4WD version which weighs 5lbs 8oz. The heaviest option is the 6WD version which weighs 6lbs 14oz. You can also add weights to the truck to increase its crawling ability.

These weights can be added to the front, rear, or both ends of the truck. Adding weights to the front of the truck will make it easier to climb over obstacles. Adding weights to the rear of the truck will help keep the back end down when climbing steep hills.

You can add as much weight as you want but keep in mind that adding too much weight will make the truck harder to control. Adding weight to your Trx4 will definitely increase its crawling ability but it’s important not to add too much weight or else you’ll lose control of your crawler. Choose your weights wisely and have fun crawling!
