Guide to Making your RC Drag Car Go Straight

An RC (Radio-Controlled) drag car is a miniature version of a drag racing car that can be controlled using a remote control. It is a popular hobby amongst car enthusiasts and children alike. While the thrill of speed and the excitement of racing are the primary attractions for many, taking control of an RC drag car requires immense skill and precision. Making an RC drag car go straight is crucial for achieving maximum speed and winning a race. However, this is easier said than done. There are several factors that can affect the car’s performance and cause it to veer off course. In this guide, we will outline the steps required to make an RC drag car go straight so that you can get the most out of your racing experience.


The type of tires used on an RC drag car is critical for achieving maximum traction and ensuring the car goes straight. Here are some tips to help you get the most out of your tires:

  • Use rubber tires with high grip to provide maximum traction.
  • Ensure that the tires are the correct size for your car.
  • Consider using a tire warming device to heat up the tires before a race, which can increase their grip.

A reliable website for purchasing RC drag car tires is A Main Hobbies, which stocks a wide range of high-quality tires that are suitable for drag racing. Additionally, a tire alignment gauge like the Imex RC Tire Alignment Tool can help ensure that your tires are aligned correctly, which can improve the car’s performance.

What kind of tires do you want for drag racing?

When it comes to drag racing, choosing the right tires is crucial for optimal performance. Here are the three main types of drag racing tires to consider:

  • Slicks: These are the go-to tires for professional drag racers. They are made of a soft compound rubber and a smooth surface to provide the best traction on the track.
  • Radials: Radial tires offer better handling and are durable, making them ideal for street racers or those with daily drivers. They have a functional tread pattern and a softer rubber compound than regular tires.
  • Street tires: These are the most common types of tires found on cars, and while not ideal for drag racing, they can still get the job done. They are made of a harder rubber compound and have a tread pattern to provide better traction on the road.

If you’re looking for drag racing tires, websites like Jegs or Summit Racing offer a variety of options to suit your needs.

Weight Distribution

The weight distribution of an RC drag car can significantly affect its stability and make it go straight. Generally, it is best to have the majority of the car’s weight towards the rear axle, which can help generate more traction and prevent the front wheels from lifting off the ground. Here are some tips for adjusting weight distribution:

Scenario Front Weight Percentage Rear Weight Percentage
Default settings 55% 45%
Wheelies or lifting the front wheels Too much weight transfer Increase rear weight by adding weights to the rear of the car
Difficulty launching or lack of traction Too much weight in the front Remove weight from the front or add weight to the rear

It is worth noting that weight distribution can vary depending on track conditions and the type of car being used. Some RC drag car enthusiasts use specialized tools like chassis scales to precisely measure and adjust weight distribution. These tools can be found at RC hobby websites like Tower Hobbies.

How do you adjust weight distribution?

Adjusting weight distribution is crucial to maintain the balance of your vehicle and improve its performance. Here are some easy steps to do it:

  • Unload unnecessary weight from your vehicle.
  • Shift heavy items towards the center of the vehicle.
  • Move load as low to the ground as possible.
  • Check tire pressure and adjust as per manufacturer’s recommendations.

Remember that proper weight distribution is essential for safety, especially when towing a trailer. More information can be found on websites like AAA, NHTSA, and U-Haul.


The suspension system of an RC drag car can also affect its stability and handling. A suspension that is too stiff can cause the car to bounce or lose traction, while a suspension that is too soft can make the car unstable or unpredictable. Here are some tips for adjusting the suspension:

  • Use an adjustable suspension system that can be set up specifically for drag racing
  • Adjust the shock dampening and spring rates to achieve optimal weight transfer
  • Ensure that the suspension is level and even on both sides of the car
  • Experiment with different suspension settings based on track conditions and the car’s performance

There are various RC suspension systems available on the market, including specialized drag racing systems from brands like Schumacher Racing. These systems typically have adjustable shock dampening, spring rates, and ride height, which can make it easier to fine-tune your RC drag car’s suspension for optimal performance.

How can I make my RC drag car go faster?

  • Upgrade the motor: A more powerful motor will result in a faster car. Look for motors with high KV ratings for maximum speed.
  • Improve the gearing: Adjusting the gearing ratio can make a big difference in speed. A higher pinion gear and lower spur gear will make your car faster.
  • Upgrade the battery: Using a high-capacity LiPo battery with a high C-rating can give your car a boost in speed.
  • Reduce weight: Removing any unnecessary weight and using lightweight parts can increase speed.
  • Tune the suspension: A well-tuned suspension can improve handling and reduce drag, allowing for greater speeds.

Proper steering is essential for an RC drag car to go straight. If the steering is misaligned or too sensitive, the car may veer off course during acceleration. Here are some tips for ensuring proper steering:

  • Check the steering linkages to ensure they are aligned and free of binding
  • Adjust the servo travel so that the steering is not too sensitive
  • Ensure that the wheels are pointing perfectly straight when the car is at rest
  • Experiment with different steering settings to achieve the desired response

There are various online forums and resources available for RC enthusiasts to ask for tips and advice on adjusting their RC drag cars’ steering. Some popular websites for RC enthusiasts include RCGroups ( and RC Universe (, which have dedicated sub-forums for RC drag racing. There are also various steering upgrades and parts available from brands like Traxxas and Tamiya, which can improve the steering performance of your RC drag car.

How do you steer a RC car?

To steer an RC car, you’ll need to use the controller that comes with the vehicle. Here are the basic steps:

  1. Hold the controller with both hands, using your thumbs to control the two joysticks.
  2. To turn right, push the right joystick to the right.
  3. To turn left, push the left joystick to the left.
  4. To go forward, push both joysticks away from you.
  5. To go backward, pull both joysticks towards you.

Keep in mind that the exact controls and maneuvers will vary depending on the type of RC car you have. Check the user manual for specific instructions.
