This steering servo has dimensions of 1.58 x 0.79 x 1.50 inches. The motor comes with a brushed, coreless design. Because of being a coreless design, it has its upper hand. 

The motor is powered by a variable voltage range of 5-7.4V. In contrast, the motor is pretty powerful.

The servo motor only weighs about 2.12 ounces. So, the motor itself is pretty lightweight but also powerful. That said, this is the lightest servo in our tier list

In a servo motor, the speed rating is really important. Let’s talk about how the speed rating is measured. Basically, it’s measured per 60-degree rotation. 

So, at its highest voltage of 7.4, the speed rating is 0.11 sec. Which is absolutely incredible.

Now, another thing is really important for a steering servo. 

That is the torque rating. Although most of companies fake it by not mentioning the correct torque rating, this one claims a torque rating of 35 kg. This is the strongest in this category.

Buying Guide

Alright, we have seen five superior steering servo products for the rock crawlers on the market. But, how will you know which one is the most suitable product for your crawler car?

Okay, the way is pretty simple. Let’s go through the basics of steering servos-

You’ll see, this segment will help you make the perfect decision.

Brushed or Brushless?

When it comes to buying a Dc motor for RC cars, the most commonly asked question is whether someone should choose a brushed or brushless motor.

The brushed or brushless motors are both the opposite. Each of them has its own pros and cons. 

A brushed motor has a low overall construction cost. It can often be rebuilt. Also, it is ideal to operate in extreme environments. 

On the other hand, the brushless motors have less overall maintenance due to a lack of brushes. Due to its reduced size, it offers far superior heat management characteristics.

Brushless motors are way more common these days because they have that great ability to alter the torque to speed ratio. 

They do it exclusively better than the brushed motors. Although the brushed motors offer better reliability and longevity.


Before choosing a Steering servo motor, always check if the motor is waterproof or not. Waterproof housings in the sensor and wires will let you drive your RC in any environment. 

It won’t matter much whether it’s raining or the track is flooded.


Question: Can I use any servo for my crawler car?

Answer: No. Not all servos are compatible with crawlers. Before buying you need to check the dimensions of the product so it fits perfectly.

Question: How much torque do I need?

Answer: 25kg is enough for a rock crawler servo. Basically steering servos come with a torque figure of 25-35kgs. We can use any of this within the range. But below 25 is not recommended.
