Analog Vs Digital Servo

Analog Vs Digital Servo: Which Is Better for RC?


To get the best from your car you need to identify the subtle variations within the components. Such as variation between analog and digital servos. Choosing one can be irritating at times.

The question remains. Which one’s favorable between analog vs. digital servo?

Well, the difference between the analog and digital servo is the momentum of each of these motors. Each of these servo motors sends and receives constant pulse signals. The analog servo sends fifty beats each second. And the digital servo sends up to a couple of hundred beats each second.

This won’t be ample for you to work out which one to go for. There’s another side to it. For that, assess the nitty-gritty variants.

Analog Vs. Digital Servo: Key Differences 

Naturally, it’s simple to assume that one has favorable performance. Though analog servo isn’t an ordinary motor in any respect. Let’s take a peek at the basic differences between analog and digital servo-

Features  Analog Servo Digital Servo
Speed Designed to transmit a continuous 50 pulse vol/s Capable of causing up to 300 pulses per second
Response Stonewall in accepting small orders  Gives a speedier reaction and quicker speed increase to the RC part
Torque   Produces a slow torque, therefore, deadband More constant torque and less amount of deadband
Power Doesn’t require high power  Requires high power

Still can’t agree on what you want? It’s okay! Lighten up and avail yourself of a head-to-head comparison.

Analog Vs Digital Servo: Head To Head Fight

Let’s have a tinge of the intricate contest between the servos.


The essential dissimilarity between the servos is the tempo of each of those motors. 

Each of these servo motors delivers and receives constant pulse signals. The analog servo sends fifty beats each second. What’s more, the digital servo sends up to a couple of hundred beats each second. 

RC servo engines’ work upheld the floods of beats sent by an order. Say from a transmitter, to create an automatic movement.

We use a servo for various purposes. For example, we tend to use a servo to manage steering by fixing the controls.


A digital servo is more costly than an analog. It’s apparent from the names which one is costlier.

The explanation why digital servos are more high-priced is that they show high-quality performance. Alongside higher speed expending. 

There are combinations in digital servos too. You can similarly get affordable digital servos that are less exorbitant. 

There are high-grade analog servos too which are better versions.

Here is a read for you on digital servo costs. Well, the HS-50 model’s costs start from $7. And this is exceptionally decent for the ones who love RC cars.

If you choose to shop for a servo for your steering, you know your options. You can pick any one of those models depending on your spending plan and conditions.


Analog servo produces additional deadband. That’s why its performance becomes sluggish. For higher performance, it needs higher pulses.

The brakes suffer as a result of the power of torque being much poorer. The acceleration and deceleration also get slower. 

This hesitance in torque isn’t suitable for developed applications. In this way, these simple servos might work in present-day RC vehicles. Yet, not in helicopters and planes. 

It’s likewise not suitable for air-borne RC vehicles or racing cars. As it generates an insufficient amount of torque

Conversely, digital servos produce more constant torque and less amount of deadband. That’s why these servos show higher performance.


The following constraint of an analog servo is, it’s non-programmable. So, you can’t optimize its efficiency. 

That’s why it gets hard to improve these servos. Even a servo saver can’t protect them for too long.

If you’re intending to buy a servo saver then we got you. Here are some pacesetter servo savers for you-

Product 1
Product 2

On the other, a digital servo is programmable. However, as it’s automated, you need to work it cautiously. Also, you need to deal with the power cautiously.

Because the moment the servo torque gets higher it will reset to staying dead. This can cause a crash. In this case, use a quality servo tester before installing the servo in your car.

Power Expending 

In advanced servos, higher measures of voltage beats are sent in each second. That is the reason the battery drops rapidly. In various words, it devours a more noteworthy measure of power.

Analog servos don’t require high power as they generate moderate amounts of voltage.

Analog Vs Digital Servo: Final Verdict 

Digital servos are considerably more productive in performing their task. In any case, this doesn’t infer that you should pick them over analog ones. 

Attempt to ponder the speed, power, and force that you prefer. And be certain if it’s necessary or not.

Choose wisely. You’ll relish better driving and acceleration on your car!


Question: Is it possible to combine digital and analog servos?

Answer: It’s possible to combine them. However, it’s not a decent plan. Providing the receiver is aware that they’re digital and is prepared for them. The circuitry inside the servo determines the frame rate, not the receiver.

Question: Why are DC motors preferred as servo motors?

Answer: DC engines are definitely less convoluted than servo engines. DC engines are likewise simple to manage. But the gap in complexity changes the resolution control for both.

Question: Are digital servos more accurate than analog servos?

Answer: Digital servos square measures much more correctly than analog servos. This can be, because of a digital servo having a swift and sleek output. Additionally, it has a pre-modified aptitude.

Last Words

Hope you’ve learned enough concerning analog vs. digital servo. Now, you shouldn’t have any difficulties selecting between these two.

Allow us to apprehend if you have got any confusion within the comment section. 

Have a pleasant day and take care!
