Essential RC Car Accessories Every New Owner Should Have

Getting your first RC car out of the box is exciting, but most ready-to-run vehicles come with just enough to get moving and not much else. The right accessories make a real difference from day one, whether that means longer run times, fewer breakdowns, or simply being prepared when something needs fixing out on the track or trail. This guide covers what to pick up right away and what to add as you get more comfortable with the hobby.

Batteries and a Quality Charger

This is the single most important purchase to make alongside your first RC car. Most ready-to-run vehicles include one battery, which gives you somewhere between 15 and 30 minutes of run time depending on the vehicle and terrain. Having at least one spare battery means you can swap and keep running instead of waiting for a charge cycle to finish.

The charger that comes bundled with entry-level kits is usually a basic trickle charger with no display, no balance function, and no way to set charge rates. Replacing it with a dedicated hobby charger is worthwhile early on, especially if you move to LiPo batteries.

NiMH vs LiPo: Which to Choose

Most beginner vehicles ship with a NiMH (nickel-metal hydride) battery. They are durable, forgiving of occasional overcharging, and do not require the same level of care as LiPo packs. They are a reasonable starting point.

LiPo (lithium polymer) batteries offer noticeably more power and longer run time in the same physical size, which is why they are the standard choice for most hobbyists after the first few months. They do require more careful handling, a compatible balance charger, and proper storage voltage management, but the performance difference is significant enough that most new owners make the switch fairly quickly.

What to Look for in a Hobby Charger

A good beginner charger handles both NiMH and LiPo chemistry, displays charge status clearly, and includes a balance charging function for LiPo packs. Balance charging monitors each individual cell in the pack and keeps them at equal voltage, which extends battery life and reduces safety risk. Look for chargers with adjustable charge rates (measured in amps) so you can charge at a rate appropriate for your battery capacity.

Essential Hand Tools

RC vehicles use metric hex fasteners almost universally, and the tools that come in most kits (if any are included at all) are usually too short or too soft to be reliable long-term. Picking up a proper set early saves frustration and prevents stripped screws.

Hex Drivers

A set covering 1.5mm, 2mm, 2.5mm, and 3mm handles nearly every screw and set bolt on most 1/8 and 1/10-scale vehicles. Ball-end hex drivers are worth the small premium, as the angled tip lets you drive screws at an offset angle in tight spots. Look for drivers with long handles or T-bar designs, which provide better torque without needing to apply excessive force.

Nut Drivers

Wheel nuts and motor mount hardware typically require 5mm, 5.5mm, or 7mm nut drivers depending on the vehicle. A basic three-piece set covers most platforms. Some hobbyists prefer a 1/4-inch drive socket set for this purpose, which gives access to a wider range of sizes and more torque when needed.

Needle-Nose Pliers and Scissors

Needle-nose pliers are useful for removing E-clips from hinge pins, seating ball ends on suspension links, and holding small parts during assembly. A pair of sharp scissors or hobby knife comes in handy for trimming zip ties, cutting foam tape for electronics protection, and general bodywork tasks.

Thread Lock

Blue thread lock (medium strength) is not a tool in the traditional sense, but it belongs in every RC kit. Vibration from hard terrain loosens screws over time, particularly on shock towers, motor mounts, and suspension arms. A small drop on each fastener during assembly keeps them in place through repeated runs without making them impossible to remove later.

Spare Parts to Keep on Hand

Certain parts break more often than others, and having them already at home means you can fix the vehicle on the same day instead of waiting days for shipping. The specific parts worth stocking depend on what you run and how hard you run it, but a few categories apply to almost every new owner.

Suspension Arms

Front lower suspension arms take the most impact in crashes and are usually the first plastic part to crack or snap. They are inexpensive and vehicle-specific, so pick up one or two sets for your model as soon as you buy the car. Most manufacturers sell them in pairs or as full sets of four.

Hinge Pins

Hinge pins are designed to bend under hard impact rather than transferring that force to the bulkheads or chassis. This means they sacrifice themselves in crashes, which is exactly the intent. A set of replacement hinge pins is cheap and easy to carry in a small parts box when running away from home.

Pinion and Spur Gears

Gear teeth wear gradually and can strip suddenly under high load. Having a spare spur gear on hand is useful for any vehicle. Pinion gears are also worth keeping, particularly if you experiment with different gear ratios for different terrain types.

Shock O-Ring Kits

Shock absorbers develop small leaks over time as O-rings wear. An O-ring rebuild kit for your specific shock size costs very little and allows you to service the shocks yourself rather than replacing entire shock assemblies. Most RC manufacturers sell these as part of their spare parts catalog.

Bearings

Bearings are a wear item, especially when running in dirt, sand, or wet conditions. A full replacement set for your vehicle (usually eight to twelve bearings, depending on the model) is worth having at home. Standard metric RC bearings are inexpensive when bought as a set, and you will need them eventually.

Lubricants and Chemicals

The right lubricant in the right place makes a meaningful difference to how components wear over time. Using the wrong product, or nothing at all, shortens the life of gears, bearings, and drivetrain parts considerably.

• Bearing oil: A thin-viscosity oil specifically formulated for RC bearings. Apply a single drop to each bearing during cleaning and after wet runs. General-purpose oils like WD-40 evaporate too quickly and leave residue that attracts dirt.
• Gear grease: A heavier grease for the spur gear, pinion, and differential gears. A thin coat reduces heat and wear on tooth faces. Available in small tubes from most hobby suppliers.
• CV grease: Used specifically in the cups of CVD driveshafts. Standard gear grease works as a substitute in a pinch, but dedicated CV grease is thicker and stays in the cup better during articulation.
• Silicone shock oil: Available in a range of viscosities measured in weight (e.g., 30wt, 50wt). The correct weight is specified in your vehicle's manual. Heavier oil provides more damping; lighter oil allows faster shock movement over rough terrain.
• Silicone differential fluid: Used inside gear differentials to control how freely the diff spins. Thicker fluid (higher weight) tightens the diff and improves traction on loose surfaces; thinner fluid gives more diff action for on-road use.

Cleaning Supplies

Cleaning the vehicle after every run is one of the most effective ways to extend component life. Having the right supplies on hand makes it a quick process rather than a chore.

• Stiff bristle brush: A cheap paintbrush or dedicated RC cleaning brush works well for dislodging caked dirt from chassis rails, suspension arms, and wheel wells.
• Soft detailing brush: A softer brush for clearing debris from motor vents, the ESC heat sink, and around the receiver without risking damage to electronics.
• Compressed air: A can of compressed air or a small compressor with a blower nozzle clears fine dust from tight spaces that brushes cannot reach.
• Microfiber cloths: For wiping down the chassis, body shell, and components after brushing. Reusable and effective at picking up fine particles.
• Isopropyl alcohol (90%+): For cleaning motor contacts, ESC connectors, and any electrical connection points. Evaporates cleanly without leaving residue.
• Parts washing tray: A shallow plastic tray for soaking and cleaning removed components like gears and diff parts. A cheap kitchen tray works fine for this purpose.

Body Shells and Protection

The polycarbonate body shell on most RC vehicles is durable but not indestructible. Repeated hard landings and rollovers eventually crack the mounting points or split the shell. Having a spare body on hand means a cosmetic crash does not end a session.

Spare Body Shell

Most manufacturers sell unpainted, clear replacement shells for their vehicles. These require cutting and painting yourself, which is a straightforward process with RC-specific polycarbonate paint applied from the inside. Pre-painted bodies are also available from third-party suppliers if you prefer to skip the painting step.

Body Protectors and Nerf Bars

Many vehicles, particularly buggies and short-course trucks, can be fitted with body protectors or side guards that absorb impact before it reaches the shell. These are usually made from flexible plastic or foam and attach to the chassis or existing body posts. They are particularly useful for bashing use where rollovers and side impacts are common.

Wing and Spoiler Replacements

Rear wings are often the first part to crack in an end-over crash. They are inexpensive and vehicle-specific. Keeping a spare wing alongside a spare body shell means you can restore the vehicle to a complete state quickly without waiting on parts.

Storage and Transport

How you store and carry the vehicle matters more than most new owners expect. Throwing the car loose in a trunk or storing batteries improperly creates problems that are easy to avoid with a small amount of planning.

Carrying Bag or Case

A dedicated RC car bag or wheeled case protects the vehicle during transport and gives you a consistent place to keep it at home. Most bags are sized by vehicle scale (1/8, 1/10, 1/5) and include compartments for batteries, tools, and spare parts. A hard case provides better impact protection for transport in vehicles without much cargo room.

LiPo Safe Storage Bag

If you run LiPo batteries, a fireproof storage bag is not optional. These bags are designed to contain the heat and flame produced by a LiPo cell failure, limiting damage to the surrounding area. Store all LiPo packs in the bag when charging and when not in use. They are widely available and cost very little relative to the protection they provide.

Parts and Tools Box

A small plastic organizer box for spare parts, O-rings, screws, and tools keeps everything together and makes running away from home much easier. Hardware store organizer boxes with adjustable dividers work well for this. Dedicate one section to spare fasteners, one to O-rings and small parts, and one to lubricants and chemicals.

First Upgrades Worth Considering

Most ready-to-run RC vehicles are well-built enough to run stock for a long time before upgrades become necessary. That said, a few areas stand out as high-value improvements that new owners often reach for after the first few months.

Bearings Upgrade

Entry-level vehicles sometimes ship with bushings (plain metal sleeves) rather than ball bearings in the wheel hubs and drivetrain. Replacing these with a full set of sealed ball bearings noticeably reduces drivetrain resistance and improves efficiency. It is one of the least expensive upgrades available and one of the most immediately noticeable.

Brushless Motor and ESC Combo

If your vehicle came with a brushed motor, upgrading to a brushless motor and compatible ESC is the single largest performance improvement available. Brushless motors run cooler, last longer, and deliver more power across the RPM range. Many manufacturers sell matched brushless combos designed to drop directly into their vehicles without modification.

Aluminum Shock Towers

Shock towers made from aluminum replace the stock plastic versions and reduce the chance of a snap under hard impact. They are a particularly useful upgrade for bashing use, where shock towers take repeated stress from big jumps and hard landings. Most aluminum shock towers are direct replacements with no additional modification needed.

Upgraded Tires

The stock tires on many beginner vehicles are a compromise suited to general use. Switching to terrain-specific tires, such as pin tires for loose dirt or ribbed tires for hard-pack surfaces, improves traction and handling noticeably on the surfaces you run most. Tires are one of the most effective tuning tools available and require no tools to swap.

Frequently Asked Questions

Do I need to buy a new charger right away?

If your vehicle came with a basic wall charger and NiMH battery, you can run with it while you get started. However, if you plan to switch to LiPo batteries or buy additional packs, a proper hobby charger with balance charging is necessary. It is generally worth buying one early rather than making two separate purchases.

How many spare batteries should I buy?

Two total (including the one that came with the vehicle) is a practical starting point. That gives you one on the vehicle and one charging, so there is always a pack ready when one runs out. Three packs become useful once you are running for longer sessions or at organized events.

Are brand-name spare parts necessary, or do aftermarket parts work?

For structural parts like suspension arms and shock towers, original manufacturer parts are the safest choice since they are built to the same tolerances as the vehicle. For wear items like O-rings, bearings, and hardware, reputable aftermarket suppliers often carry compatible parts at lower prices. Avoid very cheap generic parts from unknown sources, as fit and material quality can vary significantly.

What is the most common mistake new RC owners make with accessories?

Buying upgrades before understanding the stock vehicle is probably the most common one. It is easy to spend money on performance parts before knowing whether the stock setup actually needs improvement for your use case. Starting with tools, spare consumable parts, and a good charger gives you a much better foundation than spending the same budget on performance upgrades straight away.

Is a carrying case necessary for short trips?

Not strictly necessary, but worth having. Even short trips in a car can expose the vehicle to impacts from other cargo, and loose batteries rattling around create both safety and damage risks. A basic soft bag is inexpensive and significantly reduces the chance of arriving at the track with a broken antenna mount or damaged body.

What tools should I bring when running away from home?

A compact field kit with a hex driver set, a nut driver, spare hinge pins, a few spare screws in the common sizes for your vehicle, blue thread lock, and bearing oil covers most roadside repairs. Many hobbyists keep a small tool roll or pouch specifically for field use so it is always packed and ready to go.

Getting the Most Out of Your First RC Car

You do not need to buy everything on this list at once. Starting with a spare battery, a quality charger, a basic tool set, and a few common spare parts puts you in a much better position than most new owners. From there, adding cleaning supplies and lubricants as part of building a maintenance routine will keep the vehicle running well for a long time. Upgrades and performance parts can come later once you have a clear sense of what your specific vehicle and driving style actually call for.
