Is Weight Pulling Possible For An RC Car?

Before determining the weight capacity that an RC car pulls, we need to answer whether an RC is capable of pulling weight or not. The good news is that all RC cars are able to pull a certain amount of mass. 

Although many people don’t believe that RC cars can do so, even a small beginner RC is able to pull some considerable weight.

For most elementary-designed RC cars, they can run on flat terrain at a moderate speed. As for their speed and weights, they cannot pull weights that are bigger than their weight themselves. 

However, if an RC car uses a trailer that minimizes inclines and maintains balance, such an RC car pulls out a significant weight.

How Much Weight Can An RC Car Pull?

To determine how much weight an RC car pulls, we need to do two things: determine its mass, and calculate the weight using a math function. 

By real calculation and observation, it is evident that a typical RC car is able to pull an object with a 6-times-greater mass than the car itself. For example, a 5-pound RC car can pull up to 30 pounds. A 20-pound can pull a 120-pound object. 

However, keep in mind that you will need to upgrade the RC car’s motor to make the pulling work. Hence, it’s up to the gained traction to determine how much weight can an RC car pull.

Although every RC car is likely to pull weight, the correct amount of weight they can pull may be varied for various reasons, so the correct answer to that question cannot be found unless you study that car carefully. 

This wanted pull-weight amount relies on many factors, including the vehicle using a trailer or a sled, your RC’s power capacity, and any recent update you have recently put into the machine. 

It can be quite frustrating to understand, so let’s dig deeper into the factors affecting how much an RC car pulls!

What Are The Factors Affecting The Weight Amount An RC Can Pull?

There are many factors affecting how much weight an RC pull, but the most critical factors listed down are: 

The Wheels’ Downward Force

Spinning, bouncing, and not getting far enough will be the problem if your vehicle doesn’t have any more weight on them. However, adding a lot of weight at a time will also dry out the motor, tires, and suspension system. 

That is why it’s a good idea to add weight to the RC, as it will raise the tires’ downward force, which will increase tires and terrain’s traction. 

When the RC begins lifting, adding extra weight on the car’s front end will bring them down eventually to rely only on the terrain. This situation makes the behind tires pull weight more efficiently. 

When you test for how much weight it will be, observe the effect and result once you add weight. Remember to check the inner temperature of the motor using a temporary gun while traveling.

The Tire Traction’s Amount

One of the most effortless methods for your RC to bring more weight is to elevate the traction level of your existing tires. 

If you place too much weight on an RC, more than it can take, its wheels will lose control by spinning and jumping unconditionally, which can be dangerous if you drive that vehicle for a long time without fixing it. 

So, to increase the tires’ traction but not add more to the existing weight, soak all tires in WD-40 for more than 24 hours and clean them the morning after. This solution allows cleaning and softening the robber easily.

You can use this trick on all tires to raise their quality, whether on the road trip or urban travel. 

Tires’ Type

The traction will be there as long as there is a contract between the tire and the terrain. The bigger the slick tires are, the better they are. 

Pulling weight through a diet requires more than just an ordinary tread. It would help if you had a specialized tread that could dig through the ground. It may resemble the V-tread in tractors or like the knobbly wheels. 

The Terrain

Terrain choice can also affect the pulling capability. There are outer environmental factors that can slow down the pulling work when tires don’t have enough grip on the surface. 

For example, it’s easier to draw on Asphalt when you detect many grips on your tires. 

The RC Gearing

Gearing down the vehicle allows it to pull heavier objects. It will also be stronger to drive at low speed rather than reach high speed. If spur and pinion gear’s tooth count remains close, you will travel faster. 

However, in case of more powerful pulling power but not at high speed, try to decrease it to raise the inexpensive torque. 


We all know that bigger motors will pull much better than small ones. Although there may be exceptions, the common thing to bear in mind is that big motor applied to the car will advance in more pulling capacity.

Trailer Or Sled?

If you get a wheel-trailer, it will be much easier for RC to pull rather than pulling directly across harsh weather conditions. Wheels can maximize the pulling for both speed and power. 

Powerful Batteries Equipped

If you install a greater-capacity pin into the motor, it will perform better. It would be best if you asked the seller which batteries suit your motor and can deliver it to the best performance. 

How To Create An RC Car That Is Made For Pulling?

So, how to build an RC car that can pull weight like what you aim to get? Follow these steps below to find out the trick:

  1. Add more weight to your vehicle to raise the tires’ traction level.
  2. Overpowering the traction level by soaking them with WD-40 for more than 24 hours and washing them thoroughly the next day. 
  3. Please select the appropriate tires made specifically for each driving purpose, such as pulling tires, dry Asphalt for sticky conditions, off-road wheels on dirt roads, etc. And for updated pulling power, choose Asphalt. 
  4. Bring an RC to the lower level for more powerful low-end than top-end speeds. Get a stronger-capacity motor and install it. 
  5. Use wheels trailer rather than sled for more optimal pulling performance, and get more robust batteries. 

What To Notice To Upgrade Your RC Car For Pulling?

Wheels And Tires

Wheels and tires play an important role in deciding whether your car is ready for much-pulling power or not, so if you want to upgrade your car for pulling, getting chances on wheels and tires should be your first step. 

In terms of wheels, reach for the one with a wide base as they are built for endurance on hardship roads and traction. And as for tires, get the ones with deep treads to improve the gripping action. 

Upgraded Mounts

Putting RC in difficult runs can drain its power, especially in several components in the machine. Adding more power to the pulling machinery requires an update for the motor mount, one of the parts that are easily affected in the long run. 

Running fuel like nitro continuously will result in tons of heat, which is bad for your vehicle. Instead, replace it with aluminum heads for pulled-away heat and less weight recorded.

Motor Heat Sink

Another option for getting rid of the excess heat is to get a motor heat sink. Once you drop the temperature in the motor, there is likely an increase in velocity and the machine’s run time. 

So, keeping the inner temp controlled is essential for your motor to maintain a good condition for a long time, which results in less time visiting the garage for repairs.
