Common questions
RC car buying questions, answered
The questions people ask before they know enough about this category to ask a specific one. Every answer links to the page that covers it properly.

Before you buy
What age is an RC car suitable for?
From three with a two-button controller, from five with a simple trigger, and from about eight for a genuine hobby-grade car. The deciding factor is the controller rather than the car — proportional triggers need fine motor control most children reach around five. Full breakdown in what age is an RC car right for.
What does hobby grade mean, and does it matter?
It means the car is built from individually replaceable parts that the manufacturer sells as spares. A toy-grade car is a sealed unit, so the first serious breakage ends it. It matters enormously from about age eight, when children crash hard enough to break something. See hobby grade vs toy grade.
How much should I spend on an RC car?
Under $50 for a preschooler, $60-$100 for ages six to ten, and $150-$250 for anyone older who will use it hard. Past that you are buying performance most recipients cannot yet use. Our budget pages break down what each tier genuinely buys.
Do RC cars come with a battery and charger?
It varies, and it changes the real price by a lot. Most Traxxas and Arrma 1/10 models do not — Traxxas lists both as required extras. The Traxxas LaTrax Rally, the MJX HYPER GO models, the Axial SCX24 and most budget-brand cars do include what they need.
Why do you not show prices anywhere on this site?
Because we have no live price feed on this site, and a price figure we cannot stand behind is worse than none. Every buy button goes straight to the retailer's live listing so you see today's real price.
How fast do RC cars go?
Toy-grade cars run 5-15 mph, budget hobby cars 20-30 mph, and brushless hobby cars 35-45 mph. Traxxas states 65+ mph for the Rustler 4X4 VXL on a 3-cell battery with optional gearing. See how fast do RC cars go.
How long do RC car batteries last?
Usually 15 to 30 minutes of driving per charge against a one-to-four-hour recharge, and two to four years for the pack itself. Buying a second battery is the single most effective thing you can add to an RC car gift.
LiPo or NiMH — which battery should I get?
LiPo is lighter, faster and runs longer. NiMH is slower and heavier but tolerates being left half-charged, run flat, and charged on a simple charger, which suits a household new to the hobby. Full comparison.
Are LiPo batteries dangerous?
In normal use, no. They fail rarely, but when they do they can swell or catch fire, so the standard practice is to charge inside a fire-resistant bag and never leave one charging unattended. Follow those two rules and the risk is negligible.
What breaks first on an RC car?
Front suspension arms, almost always, then steering parts, then driveshafts. They are designed to break as a fuse so that a crash costs you a few-dollar plastic part instead of the chassis. See what breaks first.
Which RC car brand should I buy?
Traxxas for the best parts availability, Arrma for surviving abuse, Axial for crawling, Losi for mini trucks, Redcat for specification per dollar, and MJX HYPER GO for speed per dollar. Our brand guide covers each in detail.
Is Traxxas worth the extra money?
When the car will be kept, driven hard and repaired, yes — you are paying for the best parts network in the hobby. For a one-season gift or a tight budget, other brands give you more car. We answer this properly at is Traxxas worth it.
Are brushless RC cars better?
On performance, clearly: faster, more efficient and maintenance-free. For a beginner or a younger child, a brushed motor's gentler power delivery often makes it the better buy. Brushed vs brushless.
What scale RC car should I buy?
1/10 if you have a field or park, 1/16 or 1/18 for a yard or a child, and 1/24 for indoor crawling. Choose by the space you actually have rather than by what looks most impressive. Scale sizes explained.
What does RTR mean?
Ready To Run — the car arrives assembled with its electronics and transmitter fitted and set up. It does not always include a battery and charger, which is the most common surprise for a first-time buyer. More on RTR.
Can an RC car be used on grass?
A monster truck or another tall vehicle, yes. Low-bodied rally cars, drift cars and most toy-grade cars bog down on anything longer than a close-cut lawn. If the yard is the main venue, buy tall tires.
Are RC cars waterproof?
Many hobby-grade models are, meaning the electronics tolerate wet grass, puddles and rain — not submersion. It matters more than it sounds, because nobody checks whether the grass is wet first. Our waterproof picks.
Do two RC cars interfere with each other?
Modern 2.4GHz radios pick a clear channel automatically, so two cars can run side by side without any problem. Only older 27MHz and 49MHz toy radios clash, and they are increasingly rare.
Do you test the products you recommend?
No, and we will never claim to. There is no test track behind this site. Our picks are based on manufacturers' published specifications, parts catalogs, retailer listings and owner reports — set out in full on our methodology page.
