Traxxas Slash 2WD Speed: Factors and Upgrades
The Traxxas Slash 2WD has gained a reputation as one of the most popular remote-controlled (RC) trucks on the market today. Known for its speed and agility, the Slash 2WD is an exciting RC truck that can reach impressive speeds. So, just how fast does a Traxxas Slash 2WD go? While the answer to this question is dependent on several variables such as battery, gear ratio and weather conditions, a stock Traxxas Slash 2WD can reach a top speed of 30 mph. This speed is pretty impressive for an out-of-the-box truck that’s designed for off-road and on-road use. With a chassis that’s made from durable materials and waterproof electronics, the Traxxas Slash 2WD has been designed for maximum performance and longevity. From its aerodynamic body profile to its powerful motor, the Slash 2WD exemplifies speed and agility, which is why it has gained so much popularity among RC enthusiasts. While the truck’s top speed may be impressive, it’s important to know how to safely handle this machine and make modifications to improve its performance. In the following paragraphs, we’ll dive into the details of factors that affect a Slash 2WD’s speed and ways to modify the truck for improved performance.
Factors Affecting Speed
A Traxxas Slash 2WD’s speed is influenced by multiple factors. Below are some crucial determinants that regulate the speed of a Slash 2WD:
- Battery Voltage: A higher voltage battery enhances the truck’s speed. You can use a LiPo battery, which comes in different cell counts.
- Gear Ratio: Modifying the gear ratio can influence the Slash 2WD’s acceleration and top speed. A low tooth spur gear will lead to increased acceleration, and a higher tooth pinion gear can potentially increase top speed.
- Terrain: Smooth, even terrain will allow the Slash 2WD to maintain its speed, though off-road terrain may slow it down.
- Weather Conditions: An asphalt surface during hot weather can facilitate increased speed, while cold weather can decrease battery efficiency and lower speeds.
Knowing which adjustments to make can yield significant performance improvements. For more information on how to improve your Slash 2WD’s performance, products such as Traxxas’ manuals and forums are available on their website.
What can affect the speed of a car?
There are several factors that can impact the speed of a car, including:
- Engine power and size
- Transmission type
- Aerodynamic design
- Road conditions
- Tire pressure and quality
- Vehicle weight
- Altitude and air density

Battery Options
The type of battery you use can significantly affect your Traxxas Slash 2WD’s speed. Below is a table comparing different battery options that offer enhanced speed and performance:
| Battery Type | Cell Count | Volts | Top Speed (mph) |
|---|---|---|---|
| NiMH | 7 | 8.4V | 30 |
| LiPo | 2S | 7.4V | 35-40 |
| LiPo | 3S | 11.1V | 40-50 |
As seen in the table above, by upgrading to a 2S or 3S LiPo battery, you can potentially add nearly 20 mph to a Traxxas Slash 2WD’s speed. Additionally, using a higher voltage battery increases the amount of energy that is passed to the motor, increasing the truck’s acceleration and torque.
It’s essential to note that using a higher voltage battery requires certain modifications that ensure safe and efficient performance. For more information on how to make these modifications, check out Traxxas’ official website, which provides manuals and forums that cover all aspects of modding your Slash 2WD.
How long do Traxxas Slash batteries last?
Traxxas Slash batteries can last anywhere between 10 and 20 minutes depending on usage. Here are some factors that influence battery life:
- Speed: The faster you run your Traxxas Slash, the shorter the battery life.
- Terrain: Rough terrain, hills and uneven surfaces can drain battery life quickly.
- Battery Capacity: A higher capacity battery will provide longer run times.
- Temperature: Cold weather and extreme heat can affect battery performance.
It’s important to charge your battery fully before each use and avoid over-discharging it. Using a high-quality charger, such as the Traxxas EZ-Peak Plus, can help prolong battery life.
Gear Ratio Changes
Another way to increase your Traxxas Slash 2WD‘s speed and acceleration is by making gear ratio changes. Below are some gear ratio changes you can make for different performance needs:
Top Speed Changes
By adopting the gear ratio strategies mentioned below, you can optimize your truck for top speeds.
- Decrease spur gear size by 10 teeth and increase pinion gear up 1-2 teeth.
- Use a smaller spur gear and a smaller pinion gear in combination.
Acceleration Changes
To improve your truck’s acceleration, try the following gear ratio strategies:
- Increase the spur gear size by 10 teeth while decreasing the pinion gear by 1-2 teeth.
- Use a larger spur gear with a smaller pinion gear in combination.
Keep in mind that different gear ratio changes can have varying effects on your truck’s overall performance, so be sure to experiment with different combinations to find the setup that meets your specific needs.
For more information and guidance on gear ratio changes or other performance modifications, visit the Traxxas website. They provide numerous articles, guides, and tutorials on all aspects of remote-controlled cars and trucks, including the Slash 2WD.
How Does Gear Ratio Affect Speed and Acceleration?
The gear ratio is the number of turns the output shaft makes compared to the input shaft. In a vehicle, the gear ratio impacts both speed and acceleration in the following ways:
- A lower gear ratio (higher number) can provide more torque and acceleration but lower top speed.
- A higher gear ratio (lower number) can provide faster top speed but less torque and slower acceleration.
- The gear ratio can be adjusted by changing the size of the gears in the transmission or differential.
Understanding gear ratios can help drivers choose the best gear for their desired outcome, whether it’s quick acceleration or high top speed.
Battery Options
One of the largest limitations to the Traxxas Slash 2WD is its battery life and the amount of power it provides. Upgrading your battery can be a game-changer and allow you to reach higher speeds. When upgrading your battery, consider the following:
- The recommended battery size is a 7-cell NiMH battery.
- Lithium Polymer (LiPo) batteries provide more power and run longer than NiMH batteries, but usually require modifications to the electronic speed control (ESC) and motor.
- A 2S 7.4V LiPo battery can increase the speed and power of the truck by 30% compared to the 7-cell NiMH battery.
- A 3S 11.1V LiPo battery can increase the speed and power of the truck by 50% compared to the 7-cell NiMH battery.
- Always make sure to use a battery that is compatible with your ESC and motor setup.
For more information on batteries and other Traxxas Slash 2WD upgrades, visit the Traxxas website or check out other hobbyist forums and communities online. These resources often provide valuable insight into the best products and methods for remote-controlled truck enthusiasts.
Will a LiPo battery make my RC car faster?
Yes, a LiPo battery can make your RC car faster because:
- LiPo batteries offer higher voltage and sustained power delivery compared to traditional NiMH batteries, which results in higher speed and acceleration.
- LiPo batteries are lighter in weight, which reduces the overall weight of the RC car and improves its performance.
- LiPo batteries have a higher energy density, which allows for longer run times without sacrificing speed.
However, it’s important to note that not all RC cars are compatible with LiPo batteries. Before upgrading to a LiPo battery, make sure to check your RC car’s manual or consult with a professional.
You can find a variety of LiPo batteries for RC cars on websites such as amainhobbies.com or hobbyking.com.
