10 Biggest RC Cars: Largest Trucks by Scale

Scale is the number that separates these trucks, not top speed. A 1:6 Mega Grave Digger is over two feet long, while a 1:14 truggy is small enough to run in a hallway. Buyers tend to over-weight top speed and under-weight scale, and that’s backwards for a biggest rc car search. The biggest RC car here is the Monster Jam Mega Grave Digger, with the Traxxas X-Maxx Ultimate and ARRMA Kraton 8S BLX leading on capability.

Head to Head on What Matters

What to Look For in the Biggest RC Car’s Scale and Size

Scale is the first thing to settle, because it decides where you can actually run the truck. The Monster Jam Mega Grave Digger is listed at 1:6 scale and over 2 feet long, and the Eoyeskido 6-Wheel RC Monster Truck is also 1:6 scale at 68cm, which the listing says is more than 2 feet. The KIDMARKT Giant Semi-Trailer comes in at 39.6 inches long with the tailgate extended.

The ARRMA Kraton 8S BLX is 1/5 scale, which is a step up again, and the Traxxas X-Maxx Ultimate is listed with 8 inch belted Sledgehammer tires. The Uregoio Transform RC Car is 1:10 scale at 18.5 inches, the DEERC 9206E is 1:10, and the JONEALA Amphibious RC Truck is 1:12. The WIAORCHI Brushless RC Truck is listed at 1/14 scale.

What Comes In The Box

This is where the listings separate sharply, and it changes what you can do on day one. The Hosim VEXARO 1:8 ships with two 3S 11.1v 2600mAh batteries and the listing claims up to 60 minutes of running. The DEERC 9206E includes two 7.4V/1500mAh batteries for a claimed 40+ minutes, plus a spare transparent shell you paint yourself.

The JONEALA Amphibious RC Truck carries two 7.4V/900mAh batteries for a claimed 60 minutes, and the KIDMARKT Giant Semi-Trailer includes two 3.7V/1000mAh batteries with USB-C charging. The Uregoio Transform RC Car adds two 7.4V batteries, two charging cables and even two AA batteries for the remote. Against that, the Traxxas X-Maxx Ultimate and the ARRMA Kraton 8S BLX both state plainly that batteries and a charger aren’t included.

Speed And Power Claims

Speed figures only mean something when the listing states them, and several here do. The Traxxas X-Maxx Ultimate claims 50+ mph from its 1200XL Big Block brushless motor and VXL-8s ESC on 30+ volts of LiPo. The Hosim VEXARO 1:8 claims 50+ MPH on 3S, and the WIAORCHI Brushless RC Truck claims 50+ mph from its 2852 4200KV motor.

The DEERC 9206E is listed at 48+ KM/H, which is a different unit from the mph trucks, so don’t read the numbers side by side. The JONEALA Amphibious RC Truck tops out at a claimed 25 km/h. The Monster Jam Mega Grave Digger, Eoyeskido 6-Wheel, KIDMARKT Giant Semi-Trailer and Uregoio Transform RC Car listings state no top speed at all, so treat those as unknown rather than slow.

What the Numbers Mean for You

Scale changes your yard more than your ego. A 1:6 truck at this scale needs open ground, and it won’t turn inside a small living room. A 1/14 truggy fits a driveway, a park path or a basement, and it’s the size most people actually use weekly. If your space is tight, the smaller truck gets run and the giant one sits.

Battery counts matter more than peak speed for a beginner. Two packs in the box, as the Hosim, DEERC, JONEALA, KIDMARKT and Uregoio listings each state, means one charges while the other runs. A truck that needs batteries bought separately, like the Traxxas X-Maxx Ultimate and ARRMA Kraton 8S BLX, is a project before it’s a toy.

On speed, 50+ mph is a claimed figure on three listings here, and it stops helping the moment you’re on grass or gravel with obstacles. A claimed 25 km/h crawler clears rocks and water. Match the number to your terrain, not to the spec sheet.

1. Monster Jam Mega Grave Digger

Check Latest Price on Amazon

Best for: Buyers who want the biggest body

This is the biggest RC car on the list by the number the listing gives it: the largest stated size at 1:6 scale. That size is the whole point. It changes where you drive it, because a body that large needs a yard, a driveway or a park rather than a hallway, and it changes how it reads in photos next to a 1:10 truck.

No top speed is stated, so if a number on a box matters to you, this one doesn’t give you one. It’s aimed at ages 4 and up.

This isn’t the truck for someone who wants a hobby-grade chassis they can rebuild and upgrade part by part. It’s for the buyer who wants the biggest recognizable monster truck body in the yard, and who is fine with the listing’s own claims being the only performance information available.

Pros

• Over 2 feet long at 1:6 scale
• Official Monster Jam Grave Digger body
• Listed for ages 4 and up
• Seller states it’s faster than the previous version

Cons

• No top speed figure given in the listing
• Size limits it to large open spaces

2. Traxxas X-Maxx Ultimate 8s 4X4 Extreme Monster Truck (Green)

Check Latest Price on Amazon

Best for: Maximum performance and aluminum upgrades

The X-Maxx Ultimate carries a long parts list in its listing. It names 6061-T6 aluminum caster blocks, steering blocks, rear hub carriers, steering bellcranks, differential housings, gear cover, motor mounts and pin retainers, plus 7075-T6 toe links.

The power side is just as specific: a 1200XL Big Block brushless motor and VXL-8s ESC turning 30+ volts of LiPo into a claimed 50+ mph, with 8 inch belted Sledgehammer tires that the listing says resist ballooning at speed. It also includes a TQi 2.4 GHz transmitter with a Bluetooth module installed, Traxxas Stability Management and self-righting.

The trade-off is stated right in the listing: batteries and charger are sold separately. So the truck arrives ready to build a power system around, not ready to run.

Pros

• Extensive 6061-T6 and 7075-T6 aluminum upgrade list
• 1200XL brushless motor and VXL-8s ESC on 30+ volts
• Claimed 50+ mph with 8 inch belted Sledgehammer tires
• TQi transmitter with Bluetooth module, TSM and self-righting

Cons

• Batteries and charger not included
• Geared toward experienced hobbyists
• Large scale needs serious open space

3. ARRMA RC Truck KRATON 4X4 8S BLX 1/5 Speed Monster

Check Latest Price on Amazon

Best for: A 1/5 basher that runs out of the box

The Kraton 8S BLX is the 1/5 scale option here, and the listing calls it the ultimate ARRMA 1/5 scale ready-to-run Speed Monster Truck. Ready-to-run matters, because it includes the Spektrum DX3 3-channel 2.4GHz DSMR radio system, so the control side is handled.

It’s built around laser-etched EXtreme Bash 7075-T6 aluminum parts, and the listing says it’s engineered for improved strength, handling, durability and control. The power system is an 8S LiPo capable Spektrum brushless setup. That 8S capability is the headline, and it’s also the catch, because the listing states batteries and charger aren’t included.

So the buyer gets a truck engineered to bash hard, with the radio included, and then has to supply 8S power themselves. This isn’t the pick for someone who wants the simplest possible start. It’s for the hobbyist who already owns 8S packs and a charger, and who wants a 1/5 basher with the electronics and radio sorted.

Pros

• 1/5 scale ready-to-run Speed Monster Truck
• Laser-etched EXtreme Bash 7075-T6 aluminum parts
• 8S LiPo capable Spektrum brushless power system
• Spektrum DX3 3-channel 2.4GHz radio included

Cons

• Batteries and charger not included
• No speed figure stated in the listing

4. Hosim VEXARO 1:8

Check Latest Price on Amazon

Best for: Speed with batteries in the box

The VEXARO is the truck here that pairs a serious speed claim with everything needed to run it. The listing states a 3660 3100KV brushless motor, an 80A ESC with aluminum heatsink, and 50+ MPH (80+ KM/H) on 3S. It also includes two 3S 11.1v 2600mAh batteries for a claimed 60 minutes of running, so you don’t buy power separately.

The drivetrain is described in detail: a 3-differential 4WD system with central transmission, chrome steel spiral differentials, and a full metal drivetrain with medium-carbon steel driveshafts and steering links. The chassis is listed as full metal with metal suspension arms, hydraulic shocks and independent suspension springs.

The listing also makes a claim worth reading carefully: it says the reinforced metal chassis and drivetrain withstand 50% more impact than the regular RC car. That’s the seller’s own comparison, not a tested figure. This isn’t the truck for a buyer who wants a lightweight, simple first car, because the listing describes a full metal chassis and drivetrain with 3S power.

Pros

• Claimed 50+ MPH on 3S from a 3660 3100KV brushless system
• Two 3S 11.1v 2600mAh batteries included, claimed 60 minutes
• 3-differential 4WD with central transmission
• Full metal chassis, drivetrain and hydraulic shocks

Cons

• Seller’s 50% impact claim isn’t independently verified
• Metal-heavy build suits tinkerers more than beginners

5. DEERC 9206E DIY Extra Shell 1

Check Latest Price on Amazon

Best for: A first hobby-grade 1:10 truck

The DEERC 9206E is an entry point to hobby-grade running here, and the listing shows why. It’s 1:10 scale with 4WD, a 2.4GHz full-scale synchronous radio with proportional throttle and steering, and it includes two 7.4V/1500mAh batteries for a claimed 40+ minutes, roughly 20 minutes each.

Two details stand out. First, it ships with a transparent spare shell so you can paint your own, which is a genuine hobby hook. Second, the listing includes an unusually direct usage warning: avoid continuous high-speed running over 20 minutes because it may cause motor or ESC overheating, and let the car cool at least 10 minutes between uses. That’s the seller stating a usage limit, and it’s worth taking seriously.

The shocks are metal oil-filled, and the listing notes you fill the oil yourself. This isn’t the truck for someone chasing a 50 mph figure, since it’s listed at 48+ KM/H. It’s for the beginner who wants proportional control, two packs and a shell to paint.

Pros

• 1:10 scale 4WD with proportional throttle and steering
• Two 7.4V/1500mAh batteries, claimed 40+ minutes
• Extra transparent shell included for DIY painting
• Metal oil-filled shocks, oil added by the user

Cons

• Listing warns against runs over 20 minutes at high speed
• Needs a 10 minute cooldown between uses
• 48+ KM/H is stated in a different unit from the mph trucks

6. 6-Wheel RC Monster Truck

Check Latest Price on Amazon

Best for: A giant six-wheel toy for kids

The Eoyeskido six-wheeler is listed at 1:6 scale with a 68cm body. Six wheels on a body that size is the visual hook, and the listing leans into it as a kids’ off-road toy for ages 5 and up.

The running gear is described as all-terrain rugged tires with independent suspension shocks, listed for sand, grass, rocky paths, pavement and indoor floors. There are bright LED roof headlights for night driving and a durable roll cage frame that the listing says withstands bumps and crashes. The 2.4GHz radio is described as anti-interference with a long control range and support for multi-car racing at the same time.

This isn’t the truck for an adult hobbyist who wants brushless power and replaceable parts. It’s for a family that wants the biggest possible toy truck for a young driver.

Pros

• 1:6 scale with a 68cm body over 2 feet long
• Six wheels with independent suspension shocks
• LED roof headlights and roll cage frame
• 2.4GHz radio supports multi-car racing

Cons

• No speed figure stated in the listing
• No battery specification stated in the listing
• Aimed at ages 5 and up

7. KIDMARKT 39.6″ Giant RC Semi-Trailer Truck

Check Latest Price on Amazon

Best for: Hauling cargo, not racing

The KIDMARKT is the odd one out here and that’s its strength. It’s a semi-trailer, 39.6 inches long with the tailgate extended, and the listing gives full dimensions of 39.6 by 5.0 by 6.8 inches. It’s a hauler, not a speed truck.

The payload claim is the interesting one: the listing says the 4WD chassis and extra-long flatbed can carry up to 17 lbs of smaller cars, blocks or construction toys, and it names 1:20 scale RC construction trucks as a match. It includes two 3.7V/1000mAh batteries with USB-C charging for a claimed 60 minutes, and the radio is a 16-channel 2.4GHz unit that runs the cab solo, fast and slow modes, engine sounds, horn, LED headlights and dual water-vapor exhaust smoke.

It also has manual mechanics: an opening hood, adjustable tailgate and extendable lifting outriggers, with the listing noting a clicking sound during outrigger adjustment is normal. This isn’t for anyone who wants speed or jumps. It’s for a kid aged 6 to 12 who wants to move things around a yard or a carpet.

Pros

• 39.6 inches long with the tailgate extended
• Claimed 17 lb payload on the flatbed
• Two 3.7V/1000mAh batteries with USB-C charging, claimed 60 minutes
• 16-channel radio with lights, sounds and water-vapor smoke

Cons

• Built for hauling, not speed
• Manual hood, tailgate and outriggers need hands-on play
• Ages 6 and up, so not a toddler toy

8. Transform RC Car 1:10

Check Latest Price on Amazon

Best for: Transformation and stunt play

The Uregoio is a transforming car, and the listing puts it at 1:10 scale with an 18.5-inch body it calls one of the largest on the market. It switches between car and robot, which is a different kind of play from anything else on this list.

Control is dual: a 2.4GHz remote for precision, plus gesture sensing that responds to a wave of your hand. The listing describes professional-grade stunt wheels for 360 degree rotations and lateral drifts, five LED light modes and three music tracks. There’s a programming function so kids can design their own stunt sequence, and adding water triggers a rear exhaust spray that mimics a rocket booster.

It comes as a full set: two 7.4V rechargeable batteries, two charging cables, two AA batteries for the remote, a screwdriver, a water injector and a manual. This isn’t the pick for someone who wants a scale off-road truck to bash on dirt. It’s for a kid aged 6 to 12 who wants a toy that does something new every few minutes.

Pros

• 1:10 scale, 18.5-inch transforming body
• Dual control with 2.4GHz remote and gesture sensing
• Stunt wheels for 360 degree rotations and drifts
• Two 7.4V batteries plus AA batteries, tools and injector included

Cons

• Transformation and stunts rather than off-road capability
• No speed figure stated in the listing
• Water spray needs refilling to keep working

9. RC Trucks 4×4 Offroad Waterproof

Check Latest Price on Amazon

Best for: Driving through water and mud

The JONEALA is the one truck here whose listing is built around water. It’s 1:12 scale with 4×4 wheel drive and a double waterproof structure that the listing says lets you drive across a water surface. If your idea of fun involves a creek or a puddle, that’s the feature that decides it.

The rest is sensible crawler gear: tough rubber tires, an independent shock absorber at each wheel, and a wear-resistant tire design. Power comes from dual motors with a claimed maximum of 25 km/h, which is a crawler figure rather than a speed figure. It includes two 7.4V/900mAh rechargeable batteries for a claimed 60 minutes, and the listing notes a no-screw battery design so swaps take seconds.

It’s listed for ages 8 to 12 and up, plus adults. This isn’t the truck for someone who wants 50 mph on a dirt lot, because 25 km/h is the stated ceiling. It’s for a buyer whose terrain includes water and who wants longer run time from two packs.

Pros

• 1:12 scale 4×4 with a double waterproof structure
• Independent shock absorber at each wheel
• Two 7.4V/900mAh batteries, claimed 60 minutes
• No-screw battery design for fast swaps

Cons

• Claimed top speed is 25 km/h
• Crawler gearing rather than high-speed running
• No warranty term stated in the listing

10. Brushless RC Truck 1/14

Check Latest Price on Amazon

Best for: Big speed in a small package

The WIAORCHI is a 1/14 scale truck, and the listing still claims 50+ mph (80 km/h) from its 2852 4200KV four-pole brushless motor. That combination is the whole pitch: a truck that fits smaller spaces but still runs brushless power.

The chassis is 6061 aluminum, laser-etched, with a metal center body support and a composite brace. The listing says the reinforced design offers up to 50% longer durability than typical models, which is the seller’s own comparison rather than a tested figure. The drivetrain uses steel differential outdrives, metal gearbox internals and a steel universal drive shaft. The 45A ESC is compatible with 2S or 3S batteries, and the receiver is waterproof.

Two things stand out for a new owner. The transmitter has a throttle limit you can set at 70% until you’re ready for full speed, which is a real help on a truck this quick. The listing also mentions paddle tires for sand, snow and mud alongside the standard multi-terrain tires. This isn’t for someone who wants a big body, because 1/14 is small. It’s for a driver who wants speed in a compact footprint.

Pros

• Claimed 50+ mph (80 km/h) from a 2852 4200KV brushless motor
• 6061 aluminum laser-etched chassis with steel drivetrain parts
• 45A ESC compatible with 2S or 3S, waterproof receiver
• Transmitter throttle limit at 70% for new drivers

Cons

• 1/14 scale
• Seller’s 50% durability claim isn’t independently verified
• No battery count stated in the listing

Also Worth Considering

The Losi LOS05021T1 RTR is a 1/6 scale four-wheel-drive brushless desert truck, and like the Traxxas and ARRMA trucks here, it arrives without a battery or charger. The Traxxas Racer 4X4 Pro Scale is a Pro Scale race truck, which puts it in a different class from the toy-grade giants. The KB KAIBO 1:12 Large Amphibious is an eight-wheel-drive waterproof monster truck for kids aged 6 to 12, and eight wheels is more than anything else on this page.

Frequently Asked Questions

Is a bigger scale number always better?

No, and the number works backwards from what most people expect. A 1:6 truck is bigger than a 1:10 truck, so a smaller second number means a bigger car. A 1/14 truck like the WIAORCHI Brushless RC Truck fits places a 1:6 Mega Grave Digger never will.

What does it mean when a listing doesn’t state a top speed?

It means the seller didn’t publish one, and that’s all it means. It doesn’t mean the truck is slow and it doesn’t mean it’s fast. Several listings here, including the Monster Jam Mega Grave Digger and the Eoyeskido 6-Wheel RC Monster Truck, give no speed figure at all. If speed is your deciding factor, choose from the listings that do state it.

How do I compare a speed in km/h with one in mph?

Convert to one unit before you compare, because the raw numbers mislead. The DEERC 9206E is listed at 48+ KM/H and the JONEALA Amphibious RC Truck at 25 km/h, while the Traxxas X-Maxx Ultimate, Hosim VEXARO 1:8 and WIAORCHI are all listed at 50+ mph. Never read 48 against 50 as if they’re the same scale.

Does a higher battery voltage mean more speed?

Not on its own. Voltage is one part of the power system, alongside the motor and the ESC. The Hosim VEXARO 1:8 pairs 3S 11.1v batteries with a 3660 3100KV motor and an 80A ESC to claim 50+ MPH, while the WIAORCHI pairs a 45A ESC with a 2852 4200KV motor and 3S capability for a similar claim. Voltage without a matching motor and ESC gets you heat, not speed.

Closing

If scale is the axis you care about, the Monster Jam Mega Grave Digger wins with its 1:6 body. If you’re not sure which axis matters to you, the ARRMA Kraton 8S BLX is the safer choice, because it’s ready-to-run with the radio included and 8S-capable electronics you can grow into. Either way, check what’s in the box before you commit, then head to Amazon through the links above to see the full listing.
