The Biggest RC Trucks: Definitive List

When you roll up with a 30-inch, 20-pound, 8-cell monster that can flip itself upright and launch over a trash can - it feels freaking good, doesn't it?

If you’re stepping up from a starter rig or diving straight into high-power bashing, the biggest RC trucks bring a kind of presence smaller scales can’t replicate. And no, it’s not only about scale numbers. It's about stance, ground clearance, weight, and how hard you can push it without snapping a driveshaft in half.

We’ve picked the rigs that dominate the trail, survive sketchy landings, and leave a crater where your buddy’s 1/10 used to sit. We pulled real-world dimensions, pored over the specs, and narrowed it down to five machines that define large-scale RC in 2025.

Here’s what’s coming up:

• A breakdown of what makes an RC truck “big” (spoiler: scale is only part of it)

• A detailed list of the largest, baddest trucks available right now

• Side-by-side specs and comparison notes

• Buying tips for choosing the right combo of footprint, weight, terrain type, and raw power

Let’s find the truck that makes your driveway look too small.

What Makes an RC Truck “Big”?

It’s easy to assume the biggest RC trucks are the ones with the highest scale numbers. But that’s not the full picture.

Scale size (like 1/5 or 1/10) tells you how the truck compares to a real-life vehicle in proportion - but not every 1/5 truck is built the same. In fact, some 1/7 trucks have more ground clearance, wider wheelbases, and significantly more weight than a supposedly “larger” scale.

To really understand what makes an RC truck big, you need to consider four key dimensions:

1. Length and Width (Footprint)

The physical footprint is often the most obvious indicator. Trucks like the Traxxas X-Maxx Ultimate span over 30 inches long and 21 inches wide - that’s a commanding presence on any terrain. Wider trucks are more stable at speed and in corners. Longer ones soak up bumps better and stay composed on jumps.

2. Ground Clearance

Large-scale RC trucks aren’t just wider - they sit taller, too. A higher chassis lets you clear rocks, roots, curbs, or whatever else your bashing spot throws at you. Many trucks on this list clear 2-4 inches off the ground, thanks to oversized tires and tuned suspension.

3. Weight

Big trucks bring big mass. And that changes everything: how they land, how they handle, how they break (or don’t). A 20+ pound truck like the ARRMA Kraton 8S punches through rough ground without deflecting, soaks up hard landings, and carries momentum like a sledgehammer. That weight demands stronger parts and better shock absorption - but it also means more impact.

4. Power System

Brushless motors paired with 6S or 8S LiPo batteries generate 50-80+ mph speeds and torque that’ll rip gravel out of a sidewalk. The biggest RC trucks aren’t just heavier - they’re built to move that weight with brutal efficiency.

What Is the Largest RC Scale Size?

When you see “1/10” or “1/5” printed on a truck’s box, the number tells the whole story. But scale size is only part of the equation.

Depending on the model, body style, tire diameter, and stance, two trucks labeled the same scale can have completely different footprints.

The biggest common RC scales:

• 1/7 Scale: A midpoint between 1/8 and 1/5. Often found in high-speed bashers and on-road rigs, like the Arrma Mojave. Big footprint, lower profile.

• 1/6 Scale: Large and heavy-duty. Found in specialty machines like crawlers or ultra-durable monsters.

• 1/5 Scale: The true giants. Oversized bodies, massive tires, and serious weight (20+ lbs). These are the top-tier bashers that need room to run and can soak up real punishment.

So which scale is the biggest?

Technically, 1/5 scale is the largest commonly available size in the hobby market. But keep in mind: the true size of the truck depends on more than that number. Some 1/7 trucks are longer than certain 1/5 crawlers. Some 1/8 bashers run tires as big as 1/5 models. That’s why experienced hobbyists also look at things we’ve mentioned:

• Wheelbase (distance between front and rear wheels)

• Track width (side-to-side footprint)

• Ground clearance

• Weight and power system
  
  

In short: scale gives you a starting point but if you're chasing the biggest RC trucks, you need to go beyond the label and look at the full build.

The Biggest RC Trucks You Can Buy in 2025

You want size? These trucks bring it - in mass, muscle, and mayhem. We picked five models that don’t just say “large-scale” on the box but prove it in the dirt. These are the rigs that push 20 pounds, stretch past 30 inches, and throw roost like a full-size quad.

1. Traxxas X‑Maxx 8S 4WD Monster Truck (Brushless RTR)

Comparison Table: The Biggest RC Trucks

How to Choose the Right Large-Scale RC Truck

Not all big trucks are built for the same kind of driving. Some are backyard bruisers. Others are high-speed pavement rippers. And a few are basically stunt trucks with 20+ pounds of flying mass behind them.

Here’s how to narrow down which beast fits your style:

1. If You Want All-Out Bashing Power

You’re not here to drive carefully. You’re here to full-send over a park bench and watch 20 pounds of RC mass stick the landing. That’s what the Traxxas X-Maxx 8S and Arrma Kraton 8S are for. These are the most aggressive bashers in the bunch, built to survive abuse that would break most 1/10-scale trucks in half.

• The X-Maxx 8S gives you that signature self-righting feature and interchangeable belt or shaft drivetrain - ideal if you want high speed but hate walking to flip it back over.

• The Kraton 8S is heavier and has a wider track, which gives it a tank-like feel and better high-speed stability for launches, jumps, and awkward landings.

Best for: open fields, BMX-style dirt jumps, rough terrain, and full-throttle driving with lots of crash forgiveness.

2. If You’re All About Stunt Control

The Arrma Outcast 8S wasn’t designed to just go fast in a straight line. It’s a wheelie machine with wide axles, a low center of gravity, and chassis flex that works with you mid-air. It’s shorter than the Kraton or X-Maxx, but taller and wider, making it incredibly agile during flips, stoppies, and donuts.

• The included wheelie bar isn’t cosmetic - it’s necessary.

• Rear weight bias helps with backflips, and the EXB components make sure it keeps running even after some ugly landings.

Best for: stunts, freestyle bashing, skatepark-style play, and drivers who love trick driving as much as speed.

3. If You Care About Speed and Stability

Not everyone wants to bash. Some want control - the kind you feel at 50 mph when your truck holds a tight corner. The Arrma Mojave 6S is the most racer-style rig in this lineup. It’s still huge, but lower and sleeker, with a long body and stable stance perfect for speed runs and scale-realistic performance.

• At ~28.15" long and ~11.88 lbs, it’s the lightest and fastest-feeling option here.

• It handles smoother trails, fire roads, and packed dirt with confidence (and it looks like a real off-road racer doing it).

Best for: speed lovers, trail driving, scale appearance fans, and those who want better control over raw bashing force.

4. If You Want Premium Upgrades Out of the Box

The Traxxas X-Maxx Ultimate is for drivers who don’t want to wait to upgrade. It’s the same massive 8S monster as the standard X-Maxx, but with over $1,000 in aluminum hop-ups and factory-installed parts - like GTX shocks, heavy-duty steering components, chassis bracing, and more.

• It saves you hours of upgrade installs.

• It’s also a flex piece - because anyone who knows RC knows what this truck is.

Best for: experienced RC drivers who want top-tier performance immediately, with no aftermarket hunting or tuning required.

How to Choose the Right RC Truck

When you're spending $700–$1,000+ on a big RC rig, it's not just about picking the one with the longest spec sheet. It’s about how, where, and why you want to drive it - and making sure what’s under the body shell fits your terrain, battery setup, and skill level.

Here’s what to consider:

1. Terrain Type: Where Are You Driving?

Not every large-scale truck handles the same surfaces well. A 1/5 stunt truck like the Outcast 8S is made for skate parks and dirt ramps. The Mojave 6S, on the other hand, is a long-wheelbase desert truck built to glide over rough trails and loose gravel at 60 mph.
If your backyard is small or uneven, a shorter truck like the Outcast may actually be easier to control.

2. Weight vs. Durability Tradeoff

Heavier trucks (like the Kraton 8S) feel more planted and absorb harder hits but they also put more stress on components when you land or crash. Lighter trucks (like the Mojave 6S) tend to accelerate faster and fly further, but might not survive the same abuse without upgrades.
Decide if you want raw toughness or more agile handling.

3. Electronics and Drivetrain

If you want to stay in control at 50+ mph, look for trucks with:

• Smart ESCs

• Self-righting features 

• Heavy-duty drivetrains with metal gears and sealed diffs
  

These features mean fewer failures and more fun out of the box, especially if you’re running full 8S power.

4. Parts Support and Upgrades

Big trucks break big. Make sure the model you pick has strong aftermarket support. Traxxas and Arrma are leaders here: you’ll find arms, diffs, wheels, servos, and aluminum upgrades everywhere (and a massive community behind them).

5. Battery Compatibility and Charging Setup

Running a truck that needs dual 4S packs? You’ll need a charger that can balance and power them safely. If you don’t already have an 8S-compatible charging setup, that adds to the cost - so check what’s included in the RTR box and what needs to be bought separately.

The Bigger the Truck, the Bigger the Thrill

You buy a 30-inch, 20-pound RC truck because you’re ready to hit the throttle hard, land stupid-big jumps, and throw a roost that makes your neighbor stare.

If you want the all-around king? Go for the Traxxas X‑Maxx - belt-driven, self-righting, and tough enough to eat concrete for lunch.Need something heavier and more planted? The Arrma Kraton 8S brings that tank-like weight and track width that lets you stay pinned longer.

Want to fly off ramps and stick a landing? The Outcast 8S is made for stunt runs and flex.

Chasing long-range desert blasts? The Mojave 6S keeps things sleek, stable, and scary-fast.

Or, if you want the best of everything with premium parts pre-installed, the X‑Maxx Ultimate is sitting at the top.

No matter what you choose, these trucks are the kind that make people stop and watch. The ones that survive the hits, keep driving, and make you want to bring tools to the park.

Big rigs, big impact, big fun.

FAQ

1. What is the largest RC scale size?
   

1/5 scale is generally considered the largest common RC size. These trucks can measure over 30 inches long and weigh more than 20 pounds. Some even classify certain 1/4 or custom 1/3 builds as larger, but for ready-to-run (RTR) models, 1/5 scale is the top end.

2. What’s the difference between 1/5 and 1/7 scale?

A 1/5 scale truck is significantly larger and heavier than a 1/7 - often with a wider track, taller tires, and higher power requirements. A 1/7 scale rig like the Mojave 6S offers speed and length, but 1/5 trucks like the Kraton 8S bring pure mass and durability.

3. Are bigger RC trucks better for beginners?

Not usually. Large-scale trucks are heavier, faster, and more expensive to repair if something breaks. Beginners are often better off with 1/10 or 1/18 scale RTR kits. But if you’ve got space, budget, and decent control skills, some 1/5 trucks like the X-Maxx can still be beginner-friendly - just with a bigger learning curve.

4. What batteries do I need for a 1/5 scale RC truck?

Most 1/5 scale trucks run on 6S or 8S LiPo batteries (usually as two 3S or 4S packs). These provide the voltage needed to push large brushless motors to 50+ mph speeds. You’ll also want a high-output charger and hard-case LiPos with good C-ratings for durability.

5. What’s the fastest large-scale RC truck?

The Arrma Mojave 6S is one of the fastest in this lineup, topping out around 60+ mph. The Kraton 8S and X-Maxx can reach 50-55+ mph, depending on gearing and tires. With upgrades, these speeds can increase - but so does the risk.

6. Can large RC trucks self-right when flipped?

Some can. The Traxxas X‑Maxx and X‑Maxx Ultimate come with a self-righting system that uses the drivetrain to roll the truck back over. Most other models, like the Kraton or Outcast, require manual flips (or a friend with long arms).

7. What’s the best large RC truck overall?

If you want a mix of durability, performance, and upgradeability, the Traxxas X‑Maxx is hard to beat. For heavier stunt or bash work, the Arrma Kraton 8S or Outcast 8S are monsters. Your best truck depends on how you drive, where you drive, and what kind of RC experience you’re chasing.
