What Is an RC Car Gyro? A Complete Beginner’s Guide
Share
If you have been looking at modern hobby-grade RC cars, especially the MJX Hyper Go range, you may have noticed that many models come fitted with a gyro as standard.
For beginners, a gyro can be one of the best features on an RC car. It can make driving easier, improve control at high speed, and even help you pull off smoother drifts.
But what exactly does a gyro do, and how should you set it up?
Let's take a closer look.
What Is a Gyro?
An RC car gyro is a small electronic device that helps keep your car travelling in the direction you intend.
It works by detecting unwanted rotation of the vehicle and automatically making tiny steering corrections faster than any human could.
Think of it like stability control in a real car.
If the rear of the car starts stepping out unexpectedly, the gyro reacts instantly and applies a small steering correction to help maintain control.
The important thing to understand is that:
A gyro does not drive the car for you.
It simply helps reduce sudden loss of control.
Which MJX Models Have Gyros?
Several popular models sold by The Truck Monster come fitted with gyros from the factory, including:
These fast 1:14-scale rally and street cars benefit enormously from gyro assistance, especially on loose surfaces.
Some other MJX models may also feature gyros depending on the exact version supplied.
What Does a Gyro Actually Do?
Imagine driving across loose gravel.
Without a gyro:
- The rear tyres break traction.
- The back of the car swings out.
- You react slightly too late.
- The car spins.
With a gyro:
- The rear starts to slide.
- The gyro instantly detects rotation.
- Tiny steering corrections are applied.
- The car remains stable and easier to control.
This is particularly useful when:
- Driving on gravel
- Driving on loose dirt
- Running on dusty tarmac
- Accelerating hard out of corners
- Learning to drift
Does a Gyro Make You Faster?
For most drivers, yes.
Especially beginners.
A perfectly skilled driver may not need much gyro assistance, but most people can drive faster and more confidently with a properly adjusted gyro.
Benefits include:
- More confidence
- Fewer crashes
- Better straight-line stability
- Faster corner exits
- Improved high-speed control
Gyros and Drifting
One of the reasons gyros are so popular in RC drifting is that they help maintain controlled slides.
Without a gyro:
- The car can snap into a spin very quickly.
With a gyro:
- The car becomes more predictable.
- Slides are easier to catch.
- Drift angles become smoother.
This doesn't mean drifting becomes automatic.
You still need throttle control and steering input.
The gyro simply makes everything more manageable.
How To Set Up Your Gyro
Many people make the mistake of turning the gyro all the way up.
This usually creates more problems than it solves.
A good starting point is:
- 20-30% gyro gain for experienced drivers
- 30-50% gyro gain for beginners
The goal is to find the lowest setting that improves stability.
Signs Your Gyro Is Set Too Low
If the gyro gain is too low, you may notice:
- Frequent spins
- Unstable high-speed driving
- Sudden oversteer
- Difficulty holding drifts
Simply increase the gain a little and test again.
Signs Your Gyro Is Set Too High
Too much gyro can feel strange.
Common symptoms include:
- Wobbling on straights
- Overcorrection
- Delayed steering feel
- Reduced responsiveness
If the car starts "hunting" left and right at speed, reduce the gain.
The Simple Test
The easiest setup method is:
- Start with a low gyro setting.
- Drive at moderate speed on a loose surface.
- Increase gain gradually.
- Stop increasing when the car feels noticeably more stable.
- Reduce slightly if steering starts feeling unnatural.
That is usually the sweet spot.
Can You Turn a Gyro Off?
Absolutely.
Most gyro-equipped systems allow you to reduce the gain to zero.
This lets experienced drivers enjoy the raw handling characteristics of the car without electronic assistance.
Many drivers switch between settings depending on conditions.
Gyro Myths
"Gyros Are Only For Beginners"
Not true.
Many experienced racers and drift drivers use gyros because they improve consistency and control.
"Gyros Make Driving Easy"
Not really.
You still need proper throttle control, braking and steering.
A gyro simply helps you make fewer mistakes.
"More Gain Is Always Better"
Definitely not.
Too much gain can make a car feel unnatural and harder to drive.
Why We Like Gyros at The Truck Monster
At The Truck Monster, we think gyros are one of the best modern additions to hobby-grade RC cars.
For beginners they:
- Reduce crashes
- Build confidence
- Help drivers learn faster
For experienced drivers they:
- Improve consistency
- Make drifting easier
- Increase control on loose surfaces
Used correctly, a gyro doesn't take away from the driving experience. It simply helps you get more from your RC car.
Final Thoughts
A gyro is one of those features that many people dismiss until they try one.
Once properly adjusted, it can transform how an RC car feels, especially on loose surfaces.
Whether you are learning to drive, pushing for higher speeds, or trying to master drifting, a gyro can make your RC car more enjoyable and easier to control.
If you're looking for an RC car with excellent factory gyro systems, then the following MJX models are excellent places to start:
