Can you imagine just how much fun it would be to get the best RC car model?
The thing is, that excitement will soon fade—only to be replaced with a new desire for something better.
That’s just how we humans are.
If you’ve recently gotten a new model and you’re wondering how to make RC car faster, there are several modifications you can do yourself.
For that, we’ve got your back.
How To Make RC Car Faster?
After the initial adrenaline rush, most RC car enthusiasts long for something better and want to up the game.
It could be that your remote-controlled car is holding you back when you know you have more to offer.
Just like driving a real car, it would help to know the mechanical aspects of your RC car than just learning how to control it.
You don’t have to be an expert to modify your RC car and make it run faster.
All you need are few alterations to boost its speed and improve its overall performance, whether it’s on the road or the race track.
Ways To Boost the Speed of RC Cars
Remote-controlled cars can move at a surprising speed straight from the box, depending on the installed mechanism.
Even so, others want more agility on their RC cars. Here are some tips for modifying these toys:
1. Replace the Motor
Most budget-friendly RC cars for beginners come with brushed motors. These are affordable, easy to maintain, and reliable.
If you want a faster remote-controlled car, you must upgrade to a brushless motor, which runs faster and more efficiently.
However, it would help if you are an experienced RC pilot before changing into a brushless motor.
The reason? It is more complicated in several aspects. Also, it is more expensive and more complex to maintain than a regular brushed motor.
Most expensive RC car models come with an open underside, making it easier to locate and change the motor.
Take a closer look at the mechanical parts to ensure you can upgrade the motor.
After all, it is not possible to upgrade the motor of some RC car models, especially the cheap ones.
2. Adjust Motor Timing
If you could upgrade to a brushless motor, look for a dial-like marking that will allow you to adjust the timing.
This simple trick provides you with extra speed, but it may need plenty of adjusting and fine-tuning.
Ensure that the motor is disconnected from any power source before tinkering with it and making any adjustments.
Also, you need to check on the motor’s temperature, as the increase in RPM will cause it to overheat.
3. Install Powerful Batteries
Most RC cars come with a standard rechargeable battery. Upgrading to a lithium polymer type helps enhance your vehicle’s speed.
This high-output battery offers more power but comes in a lighter pack than the original ones with the RC car.
However, these li-po batteries need an appropriate charger and are more expensive and harder to use.
Before upgrading to this type of battery, check that your RC car’s motor can handle the additional power.
Too much battery power can cause permanent damage to your RC car’s motor, so the safest way to go is through a gradual increase.
Once you have made the upgrade, ensure that you charge the batteries regularly.
It is best to be systematic with how you replenish the cells.
4. Adjust Gear Ratio
If you are not ready to spend a lot of money just yet, you can start by modifying the gear ratio for a speed boost.
All remote-controlled cars come with adjustable pinion and spur gears for better acceleration.
The pinion gear is directly attached to the motor and is made of either aluminum, steel, or titanium.
The pinion is available in different pitches and sizes and is easily removable with a hex.
That said, a higher teeth count will help your RC car reach its fastest top speed.
Similar to the principle of upgrading the batteries, too much increase in teeth count may cause overheating and damage to your RC car’s motor.
For faster acceleration on the road, you can choose a small pinion with fewer teeth without fear of overheating the motor.
On the other hand, the spur is the larger gear made of plastic, providing quicker acceleration or faster top speed.
Smaller spur gear offers less acceleration with a higher top speed, but a more prominent one provides a lower top motion with faster acceleration.
Changing both pinion and spur gears will provide better performance results for your RC cars.
5. Replace Bushings with Ball Bearings
Most affordable RC cars have cheap brass bushings that allow the wheel to turn on the axle.
These low-quality bushings are not for high-output performance and will only slow down your RC car’s performance.
Replace these bushings with high-quality ball bearings instead, which can spin more freely, eliminate drag, and reduce engine strain.
6. Change Tires
It’s very important that you use the appropriate tires for the surface you intend to drive on.
Wrong tires can slow down your RC car’s motion.
Choose slicks if you are driving on the tarmac or the road. Full spikes are better for slippery mud or grass, while mini pins are for carpets.
The mini spikes are your best option if you are looking for all-around tires with a good grip.
Remember to always use high-quality tires for better traction and durability.
Also, tires with bigger diameters let you cover more surfaces with each turn, increasing the speed.
However, this will also mean additional weight to your RC car, slowing down its movement.
7. Reduce the Weight
Speaking of weight, changing the heavy parts of your RC car into lighter ones will significantly help make it go faster.
You can choose parts made from lightweight materials like aluminum, carbon, and graphite.
Changing one or two parts may seem nonsense, but it can still make an impact on your RC car’s overall performance.
As mentioned, li-po batteries are more lightweight than the original pack installed in your vehicle upon purchase.
Therefore, changing your battery pack will lessen the overall weight of your RC car, improving its speed.
8. Check the Suspension
Always remember to check the RC car’s shock absorbers and suspension arms, ensuring that these parts are clean and well-maintained.
Also, the shafts for the shocks should match, and the oil from the shock absorbers is changed regularly.
Lastly, only use the correct height clearance for your RC car based on your chosen terrain.
Off-road models need a higher height allowance, while a lower margin is perfect for on-road ones.
Constant Practice Is Key
Apart from all the tips discussed earlier on how to make RC car faster, constant practice is still the simplest way to do it.
Find the time to practice manipulating your car after making alterations so that you can get used to it.
The more you practice, the better you will understand how a remote-controlled car works.
