Things to Consider Before Purchasing Servo for Xmaxx 8s

Well, we already know how important a servo is for any RC truck or car. And when it’s about Xmaxx 8s, the importance of a servo is more.

Because we might not want to compromise with the speed of your monster RC truck. But, finding the best servo, of course, is not easy work. So, to make your task easier, here we are talking about some characteristics. You should check those characteristics before buying one.


The brand is always an important factor when you are buying anything for your RC. There are few prominent brands that dominate the market of RC products. So, choosing the perfect brand is always a plus point.

There are some well-renowned brands for servo motors. While you are choosing a servo for your Xmaxx 8s, you can pick any of those. Some good brands for Xmaxx 8s are Power hobbies, Traxxas, BETU power HD, etc. 


The main purpose of your servo is to generate high speed with good control. To get a great servo that can produce a great speed, you must look forward to torque.

You have to check the torque to assume what speed that servo can generate. So, before buying one, you must check the speed and timing. More precisely the torque speed.


As Xmaxx 8s is a monster RC truck, we can run it over any surface. The path won’t always be the same. It can be wet and muddy. As the servo remains in an open part of your RC, it’s necessary to save construction. 

The best safe construction starts with a waterproof feature. As you are planning to run your Xmaxx 8s in different locations, so must go for the waterproof one. With a waterproof servo, you can also run it over wet grasses or muddy surfaces.

Strong Construction

Another important factor for a Servo is its durability. The servo’s construction must have to be strong and robust enough. For strong construction, you might look for that servo that has a strong casing. 

This casing can be made of aluminum or stainless steel. Whatever the material is, you must have to ensure that your servo is strong enough. 

Size and Compatibility

You must consider the size of your Servo. If the servo is too large or smaller than your need, then it won’t help you. You must check the compatibility of the servo according to your RC. For X-Maxx 8s, all our listed servos are compatible.


Budget is always an important factor for any product. If you want to buy a powerful servo, you must pay more. To fix your budget according to your need and affordability.

Don’t buy shitty products with more money. All our listed servos are budget-friendly. You can choose any of them. You won’t regret it.

How Do Servos Work In RC Trucks?

Servo is a powerful electric motor. It is used in Rc trucks. It generates voltage and power to run an RC truck.

Servo helps to rotate the RC. Some servo has powerful casing where some don’t have. Whatever servo helps to rotate the wheel and give directions to the Rc truck.


With my standard trx4 ESC, how many volts/amps can such a servo handle?

The servo’s maximum voltage is 8.4 volts.  you can only reach it by wiring straight to the battery. If my memory serves me correctly, the stock ESC only outputs roughly 5 volts. So you’re nowhere near the maximum.

Will the power hobby 729 Mbl be compatible with an e Revo 2.0?

Yes, the E-Revo 2.0 will support it. Since the Revo operates on Two steering servo motors you could need 2. Because Traxxas servo will not have the same torque. you want to maintain the servo motors the same.

Does Power HD ⅕ scale work on Xmaxx 8s?

Yes, Power HD ⅕ scale will work on the xmaxx. But fabrication and a lot of prototyping are required. This was recently put on top of our receiver box this past weekend. 

Final Verdict

Well, after a long ride, we come to an end. You might already have picked the best Servo for your Xmaxx 8s.

All our listed products are best for your X-Maxx 8s. So, if you haven’t bought one yet, pick the best one that suits your requirements. Have a nice day!
