Upgrading a Cheap RC Car

How these radio-controlled cars work is fascinating. But your RC car can slow down anytime. That’s when you have to upgrade them. 

So, we’ve mentioned 3 ways to upgrade your RC car. You have the option of selecting all of them or any of the upgrade processes. They will increase the efficiency of the car. 

Way 1: Upgrade the Tires & Wheels

If you are an RC racer, you understand the significance of tires and wheels. The only items that come into contact with the surface are these. So, how to upgrade them?

Step 1: Choose the Tires and Wheels

When drifting, friction and traction occur at the same time. Moreover, one must understand turning speed, and slip ratio to do drift. Therefore, you will need good quality drifting tires and wheels.

Choosing the right tires for your wheel is crucial. Spiked tires can generate good traction on dirt and grass. But they will increase the weight. 

On the contrary, mini-pin tires are great for flat surfaces. They don’t perform well in dirt or sand. Instead, they are for street slicks like concrete and asphalt or any hand abrasive surface. 

Step 2: Placing Tires on the Wheels.

Now, you have to mount the tires. You can accomplish this by placing tires on the wheels. Then place them onto the axles of the RC car. It would be better if you use glue on your RC tires.

Next, you have to check if any of the wheels are imbalanced. If not, you are good to go. You can even purchase tires and wheels separately. Then glue them together to customize them as you prefer. 

Way 2: Change the Batteries and Charger 

You are not getting enough power while driving the RC car? The car is taking more time to charge than before? Then you should change your battery. 

Step 1: Select the battery

There are many batteries and chargers that come in a combo. You can buy any one of them to get a satisfactory result.

Professional RC racers always keep their batteries upgraded. Batteries are not just energy providers. They will keep the RC car long on the track. Most importantly you will definitely see the improvement in the efficacy of RC cars. 

Step 2: Replace the Battery 

Begin with finding the notch to open the cover. Then, with a screwdriver, remove the battery cover.

Next, determine the battery type. Now, swap out the old battery for a new one. Lastly, shut the cover tightly. 

Way 3: Replace the Gears

If you’re not getting enough speed, this upgrade could help. Replacing the gears will improve the performance. This upgrade is important for Traxxas Stampede 4×4 too. 

Step 1: Adjust the Gear Ratio

Adjusting or changing the gear ratio is a low-cost and easy task. Every RC car has two gears. One of them is spurs gear and another is pinion gear. 

The pinion gear with more teeth makes the car fast at the top end. And with fewer teeth, the pinion gear improves the acceleration instead of top speed. 

Step 2: Upgrade the Spurs 

Upgrading the spurs can also improve speed and acceleration.

Now, for this upgrade, remove the fuel tank and engine screws. Then take out the gear you want to swap or change. 

Next, install friction pegs. After that, Install new gear. Reconnect the fuel tank and then adjust the gear mesh. 

Lastly, use a top-notch RC hauler bag to keep it safe and carry it easily. 


How can you determine the speed of RC cars?

Answer: A radar gun is the first method for determining the true speed of an RC car. A radar gun is employed by law enforcement to detect the speed of actual autos. All you have to do when you pull the trigger is point it at your RC car. You can also point it in the direction of where the car will be passing.

Question: What is a decent RC car speed?
