Traxxas 2056 High-Torque Waterproof Servo
I am going to start with the Traxxas 2055 High-Torque Waterproof Servo. It is the best servo on today’s list. The performance of this one is greater than all the other servos. Let’s see which qualities made this servo superior to others.
The best aspect of the Traxxas 2055 servo is its lightweight. It weighs only 0.352 ounces. The weight of the servo is very significant for the remote-controlled vehicle. Because a too heavy servo can cause hindrance in its journey.
However, the torque generated by the servo could have been better. It can produce 86 oz-in torque. This is quite lower than the other servos in today’s discussion. Anyway, this low torque is compensated by the 0.23 sec/60* transit time and weight.
The servo is made from high-quality materials. The built materials are another important aspect of servo motors. Because without premium quality materials, the servo will not last long. The built materials also affect the servo performance.
Superior quality plastic has been used in the servo. The servo is designed to be waterproof. As a result, the Traxxas 2056 servo can be used in harsh and rough surroundings. It is very useful for bashing and drifting purposes.
The transit time of the servo is also impressive. Traxxas 2056 has a transit time rating of .23 seconds per angle. That means the servo needs .23 seconds to rotate the shaft one degree. This is a very good speed for remote-controlled motors.
The price of the servo is also reasonable. Despite its waterproof design with light and premium materials, the servo comes at a medium price. This makes this servo a value-for-money product. All these qualities have made the Traxxas 2056 the best.
Pros
- The weight of the servo is very low.
- Comes at a reasonable price.
- Very fast transit time.
Cons
- The torque of the servo is low.
Redcat Racing Hexfly HX-15CS Servo
Next I have the Redcat Racing Hexfly HX-15CS Servo. This one comes in second among the other servos. It has a midrange torque production and weight. Let’s check some other useful qualities of the Redcat HX-15CS Servo.
The visual appearance of the Hexfly servo is quite appealing. It comes in a combination of red and black color. The color composition of the servo is more exceptional than the other models. Besides the color, it also has a very premium design.
The servo is splash-proof. That means the servo can go through some small to medium splashes of water. The Redcat servo can be used in boats and cars without many problems. However, it is not completely waterproof. So it can’t be submerged in water.
Redcat servo has a torque production rate of 125 oz-in. It is the third highest torque among the rest of the RC servos. This 125 oz-in torque is enough to dictate the 4×4 Slash shafts. Anyway, the torque of the Redcat servo can be increased.
This servo runs at both 4.8 and 6 volts. The above-mentioned torque is 4.8 volts. If the Redcat HX-15CS Servo is supplied with 6 volts, the production increases. Then it can generate up to 132 oz-in torque. This is a very attractive quality.
It is made from premium materials. Metal gears are used inside the Redcat servo. These gears are more durable and resistant to wear. As a result, the servo lasts long and provides very good service.
Despite these gears, the weight of the servo is quite low. It weighs only 2.11 ounces. It comes in third in terms of weight. The price of the servo is also low. It comes at a cheaper price than the Traxxas 2056 model.
Pros
- Use of metal gears increases the lifetime.
- The price is very low.
- Attractive color combination.
Cons
- The mounting area of the servo is weak.
Traxxas TRA2080X Servo

The servo weighs only .632 ounces. This weight makes it the second lightest servo option. The only servo which is lighter than the Traxxas TRA2080X is the Traxxas 2056 High-Torque Waterproof Servo. However, this one lags in torque production.
The servo can generate only 41.70 oz-in of torque. In this aspect, the Traxxas TRA2080X comes in last in the least. Despite this low torque, the servo does an amazing job of controlling the shaft. It has a very fast response time.
The design of the Traxxas TRA2080X is waterproof. So water can not get inside the servo. This quality makes the servo useful for rough conditions. Also, the servo can be used with the motors of boars without any problem.
Metal gears are used in the servo. Gears transmit the power in the servo. They go through immense force and pressure while doing so. For this reason, high-quality gear is needed for long-lasting performance. And metal gears are the best for that.
The price of the servo is higher than the previous two servo models. The price of the Traxxas TRA2080X servo makes it less popular. However, the price is justified for its specifications and performance. It is a very efficient upgrade to the stock servos.

The torque generation power of the Savox servo is very high. It has the best torque-producing ability in today’s servo list. It can generate 416.6 oz-in torque. All the other servos fall miles behind the Savox servo in this significant aspect.
But while ensuring high torque production, manufacturers didn’t pay much attention to its weight. It is the heaviest servo on our list. The servo weighs about 5.1 ounces. This huge weight will surely cause a hindrance in the RC vehicle’s motion.
A high-quality case has been used in the exterior of the Savox SA1230SG servo The case is made from aluminum. Aluminum is a premium material. It has a strong resistance against corrosion and other wear. However, the servo is not waterproof.
So carefulness is a must while using it around water. Inside the servo, steel gears are used. Steel is another very high-quality material. The steel gears offer long-lasting and efficient performance. The 2BB gears are also of very superior materials.
The speed of the servo is also very fast. It has a very fast response. So the servo can be controlled at a fast pace. This servo is very useful for drifting purposes. Also, the manufacturers guarantee green manufacturing of the servo.
So if you care for the environment, this one’s for you! But the price of the Savox Monster servo is very high. It has a price twice of the Traxxas TRA2080X model. It comes at a price of around $80. This can be a problem for many buyers.

Buying Guide
You can select the best servo for 4×4 Slash from the above discussion. But there are some factors you need to emphasize while selecting the servo. We will go through these factors in this section.
Torque
The first and the most important factor for any servo is its torque-producing ability. Torque means the force applied by the servo for rotating purposes. The higher the torque will be, the smoother will be the control. So check the torque of the servo beforehand.
Weight
Next you must check the weight of the servo motor. Because weight plays a crucial role in the speed and motion of RC cars. Don’t select a too-heavy servo motor for its high torque production. It will surely affect the overall speed of your RC car. The servo should not weigh more than 6 ounces. Also, the lighter the better.
Response Time
The response time of the servo motor is very significant for its performance. A fast response time means the motor will respond to the signal fast. It is important for racing and drifting purposes. If you are going to use your Slash 4×4 for these works, check the response time. Anything around .2 seconds should be ideal.
Compatibility
Last but not least, the compatibility of the servo is an important issue. The servo must sync with the rest of the car parts. Or else it will bring negative results in the overall performance. So check the compatibility factors before getting the servo.
Check these issues to avoid any hassle while selecting the best servo for your 4×4 Slash.
