When it comes to maintenance and care, check the chassis for bends, dents, or breakages that may impact performance.
Suspension System
A key part of your car's handling capability, the suspension system absorbs shocks and keeps the tires in contact with the ground. This system typically includes components like springs, dampers, and links. Inspecting the suspension system for damage or wear is important for maintaining your car's responsiveness.
Wheels and Tires
The wheels and tires provide the grip and traction needed during acceleration, steering, and braking. Maintaining their condition through regular checks for wear and tear is crucial for ensuring the best road performance.
Motor
RC car motors can be divided into two categories: brushed and brushless. Brushed motors have been used in RC cars for decades, while brushless motors provide a longer lifespan and better efficiency. Motor maintenance will vary depending on the type of motor you have.
Electronic Speed Controller (ESC)
The ESC connects the motor and battery and controls the car's speed. It is vital for providing the precise control required in racing situations. Be sure to monitor the ESC's temperature, as overheating can lead to damage or power loss.
Battery
The battery is the power source for your electric RC car and, as such, should receive special attention regarding maintenance, charging, and storage. There are two main types of batteries used in RC cars: Nickel-Metal Hydride (NiMH) and Lithium Polymer (LiPo), both of which have specific care guidelines.
Transmitter and Receiver
The transmitter is the remote control you, as a driver, hold, while the receiver is the component inside the car that receives the radio signals from the transmitter. Proper care of these devices ensures a strong and consistent connection between you and your car.
Now you have a basic understanding of your RC car's components, you can move on to the next section, where we will discuss basic maintenance tips to keep your car in prime condition and ensure high-quality performance.
An Introduction to Basic Maintenance

Regular Cleaning
Regular cleaning is fundamental to your RC car maintenance routine. Dirt and debris can cause wear and tear, reduce performance, and even cause certain parts of the car to malfunction.
Cleaning the External Parts
Opt for a simple, soft brush to sweep off any loose dirt on the body of the RC car. For more stubborn dirt, a gentle spray with a hobby-grade RC cleaner should do the trick. Dry off the car with a soft cloth before storing it.
Cleaning Intricate Mechanical Sections
The car's internal parts, such as the gears and suspension, should also be cleaned regularly, making sure to remove all dust and any foreign particles. Fine brushes or compressed air cans can be used for these delicate parts. Be careful not to damage them while cleaning.
Battery Care
The battery ultimately dictates the performance and lifespan of your RC car. Avoid completely draining the battery before recharging it, as this can significantly shorten the battery life. For NiMH batteries, a slow, steady charge is best to prolong battery life.
For LiPo batteries, never let the voltage per cell drop below 3.0V. Always store batteries in a cool, dry place and check them regularly for swellings or leakages.
Tire Check & Replacement
Regularly inspect the tires for signs of wear and tear. Tires that are worn out can greatly reduce the RC car's grip and traction, negatively affecting performance. Also, ensure the tires are clean and free of debris. Replace tires as needed, depending on their condition and usage level.
Check Alignment & Tighten Screws
Before each run, ensure the wheels are properly aligned and all screws and parts are tightly secured. This will prevent loosening due to the vibrations from the moving RC car. However, avoid over-tightening, as this can strip the screws and render them unusable.
Incorporating these basic maintenance practices into your routine will go a long way in ensuring that your RC car stays in top shape, providing the best performance and durability over time.
Next, we'll delve into more advanced maintenance procedures for those looking to gain an extra edge in the performance of their RC cars.
Your Guide to Advanced RC Maintenance
Once you're comfortable with basic maintenance, you can move on to more advanced maintenance techniques. These are designed to further enhance your RC car's performance and longevity.
Servicing the Motor
The motor directly influences the speed of your RC car. Depending on the type of motor your RC car has, the maintenance process varies.
Brushless Motor Maintenance
Brushless motors require less maintenance compared to their brushed counterparts. However, occasional cleaning and bearing lubrication are required. This involves carefully disassembling the motor, cleaning the rotor and interior with proper cleaners, and applying a bearing oil on the bearings.
Brushed Motor Maintenance
Brushed motors need a bit more focus. They involve cleaning the commutator (the part of the motor where the brushes make contact), replacing the brushes when worn out, and lubricating the bearings.
Gear System Maintenance
Your RC car's gears need occasional cleaning and inspection for wear or damage. Any broken or worn-out gears must be replaced immediately.
After every few runs, remove any dirt or grit lodged in the gear teeth with a brush or compressed air, and apply a thin layer of a suitable lubricant to ensure smooth operation.
Tuning the Suspension
Tuning the suspension affects how your RC car responds to various terrains, jumps, and driving conditions. Making small adjustments to your car's suspension can dramatically improve its performance.
This can involve changing the shock oil, adjusting the preload on the springs, or changing the angle of the shock absorbers.
Experiment with different setups to find the best configuration for your specific driving style and conditions.
Camber Adjustment and Wheel Alignment
Camber refers to the angle at which the wheels are tilted in relation to the vertical axis when viewed from the front. Adjusting the camber can change how your RC car handles during cornering, improving performance.
Proper wheel alignment is also important for optimal handling. This includes adjusting the toe angle, which is the angle between the steering axis and the vertical axis when viewed from above. Regularly check the alignment of your RC car and make adjustments as needed to ensure it handles at its best.
Advanced maintenance practices offer the opportunity to further enhance the performance of your RC car.
By combining basic maintenance routines with advanced techniques, you can keep your RC car in excellent condition, extending its life and maximizing its potential on track or off-road adventures.
The Break-In Procedure for Nitro Engines
Unlike electric models, Nitro engines need a proper break-in procedure to ensure that they run efficiently and last longer. This procedure largely involves the first few tanks of fuel you run through your vehicle.
Let's take a look at a simple yet effective break-in process for nitro engines.
Preparation
Ensure the RC car and the engine are in pristine condition. Follow the manufacturer's assembly instructions and be sure that everything, including the glow plug and air filter, is correctly in place.
