Hobbyists looking to enhance performance, durability and extend the life of the trucks, they tend to upgrades the RC truck which is more than just to add few new parts. Whether you’re racing on rough terrain or cruising for fun, your right upgrades strike a balance between speed and durability. Stock models also perform well, but they show limitations at a certain level.
The key to effective upgrades is finding the right balance between speed and durability. This balance ensures that your truck can meet high-performance demands while also enduring the wear and tear from intense runs.
1. Upgrade the Motor for More Speed
If you want a noticeable boost in your RC truck’s speed, upgrading your RC truck’s motor is one of the best investments you can make. Its performance and efficiency depend on the type and size of motor you choose.
RC trucks usually come with a brushed motor, but if you need more power, torque, and efficiency, switch to a brushless motor. Here are the benefits of both motors:
Benefits of Brushed and Brushless Motor
| Feature | Brushed Motor | Brushless Motor |
|---|---|---|
| Cost | Affordable | More expensive upfront |
| Ease of Use | Simple, beginner-friendly | Requires compatible ESC & setup |
| Maintenance | Higher | Low |
| Durability | Shorter lifespan | Longer lifespan |
| Efficiency | Less efficient, more heat | Highly efficient, runs cooler |
| Battery Life | Drains battery faster | Better power use, longer runtime |
| Best For | Beginners, casual use | Hobbyists, racing, off-road power |
Best Motor Sizes for RC Trucks
Choosing the right motor size is just as important as deciding between brushed and brushless. Motor sizes are usually labeled with numbers (e.g., 540, 550, 775) that indicate their physical dimensions and, indirectly, their power output. Here we are discussing the common motor sizes and their features:
| Motor Size | Best For | Features & Benefits |
|---|---|---|
| 540 Motors | Standard 1/10 scale trucks & buggies | Balanced power. Lightweight and efficient. |
| 550 Motors | Heavier 1/10 scale trucks, short course trucks | More torque and better cooling make it ideal for off-road driving |
| 775 Motors | Big, heavy RC trucks & crawlers | High torque for climbing and pulling. |
| 1/8 Scale Motors | Monster trucks, truggies, and high-performance racing | Extra-large motors deliver massive torque and speed which handles big jumps |
2. Improve the Battery & Power System
Upgrades for your RC truck’s power system are essential. Just as you would upgrade the motor, it’s important to enhance the power system as well. The high-quality battery and the ESC (Electrical Speed Control) deliver the power output for speed and performance.
Switch to LiPo Batteries
LiPo (Lithium Polymer) batteries deliver faster acceleration & longer runtime compared to NiMH batteries. 3S or 4S LiPo when paired with the right motor and ESC can boost top speed. LiPos are lighter and more efficient than NiMH packs.
Install a Better ESC (Electronic Speed Controller)
A quality ESC supports higher power motors and LiPo batteries, which prevents overheating during high-performance runs. Many ESCs offer adjustable settings to improve efficiency and smooth power delivery.
Upgrading both the battery and ESC ensures your RC truck runs faster, longer, and more reliably.
3. Reinforce the Suspension System
The suspension system absorbs shocks from jumps and rough terrain, allowing the driver to maintain control. A powerful suspension system is critical to keeping your RC truck stable, whether you’re racing on a flat track or bashing through the roughest terrains.
Upgrade Shocks
Upgrading shocks will provide better suspension control, which boosts handling at high speeds and also enhances durability by absorbing impacts and reducing chassis stress. Clean shocks after runs to remove dirt and debris.
Key Upgrade Options:
- Oil-filled shocks provide better stability on rough terrain.
- Adjustable shocks let you fine-tune for racing or bashing.
- Aluminum shock bodies are more durable and resistant to cracking than plastic.
Stronger Suspension Arms
- Replace plastic arms with aluminum for added durability.
- Carbon fiber arms offer lightweight strength for racing.
- Reinforced arms reduce flex during high-speed turns.
4. Tires & Wheels Upgrades
Tires and wheels directly affect traction, speed, and durability on different surfaces. Choose terrain-specific tires: use off-road tires for better grip on dirt, gravel, and grass, and use slick tires for on-road driving. Beadlock wheels prevent tire slippage at high speeds, whereas aluminum wheels add extra durability on rough terrain.
5. Strengthen the Drivetrain
Power from the motor is transferred to the wheels via the drivetrain. A stronger drivetrain ensures your RC truck can withstand increased speed and power without needing frequent maintenance. Regularly inspect and lubricate drivetrain components to maintain performance and longevity.
For a longer lifespan under strong loads, choose metal gears rather than plastic ones. Shafts made of steel or aluminum are less likely to twist or break. Hard-Working Differentials Manage the additional power coming from LiPo batteries and brushless motors. Universal joints, often known as U-joints, lessen wear and transfer power more smoothly.
6. Protect the Chassis
Maintaining the durability of your RC truck requires protecting the chassis, particularly when you’re off-roading or racing at high speeds, where collisions and debris can seriously harm your vehicle. Key upgrades for chassis protection are
- Heavy-duty bumpers absorb crash impacts.
- Skid plates protect the underside from scratches and cracks.
- Chassis braces reduce flex and add strength.
7. Cooling & Heat Management
Significant heat generates in the motor and ESC due to high-speed runs, which can reduce performance and lifespan.
Recommendation:
Add a motor heat sink with a fan or a dual-fan ESC cooling system for better airflow. Use thermal paste with heat sinks for maximum efficiency. Avoid overheating and keep airflow clear by cleaning dirt and debris from vents.
8. Upgrade the Steering System
For high-speed control, a stronger servo enhances steering responsiveness and precision. manages the high torque requirements of racing and off-roading. For smoother movement, replace the steering assembly’s ball bearings. To safeguard the servo from collision impacts, install a servo saver.
9. Aerodynamic Body Upgrades
Your RC truck’s speed and stability are greatly influenced by its aerodynamics; at higher speeds, in particular, an aerodynamic body makes it easier for your truck to cut through the air and maintain its position on the track. RC truck bodies that are lightweight reduce total weight while improving handling. Wings & spoilers increase stability at faster speeds. Stronger body mounts keep the shell secure during crashes.
10. Essential Maintenance Tips After Upgrades
Upgrading your RC truck’s durability and speed can turn it into a high-performance vehicle that can tackle any obstacle, but maintaining it regularly is what keeps it performing at its best. After every run, make sure the screws, bolts, and nuts are tightened. While driving off-road, they are more vulnerable to dirt, dust, and debris, so clean up every time.
Examine moving parts like driveshafts, bearings, and gears for wear or damage, and where needed, relubricate them. Monitor the batteries and electronics closely, and replace any worn-out parts before they lead to more significant issues.
