The Arrma Fireteam is the most distinctive truck in the Arrma lineup — a military-themed 1/7-scale speed assault vehicle that looks like it rolled off a battlefield and drives like it’s trying to escape one. Built on the proven XLWB Mojave platform with Kraton-width suspension arms, it delivers genuine 6S brushless performance wrapped in a multi-panel polycarbonate body complete with a full roll cage, turret detail, and four-figure crew that no other major RC brand comes close to replicating.
This full Arrma Fireteam review covers GPS-verified speed, real-world handling, durability, known issues, the best upgrades, and how it compares to the Infraction 6S and Felony 6S — so you know exactly what you’re getting before you buy.

What Makes the Fireteam Different?
The Fireteam’s selling point is immediately obvious: it’s the only military-themed speed truck from a major RC brand, and nothing else on the shelf looks like it. The multi-panel polycarbonate body is bolted to an integrated structural roll cage, with a turret detail, military camo paint scheme (black or white camo), and a four-figure crew inside the cab. At a local park, kids and adults alike stop mid-step to stare at it. It doesn’t look like a toy because it’s not.
Under that body lives Arrma’s XLWB (Extra Long Wheelbase) platform — the same 3mm aluminum chassis plate used in the Mojave V2, fitted with Kraton 6S suspension arms for maximum track width. This is a critical distinction worth spelling out clearly: the Fireteam is not an Infraction with a different body, despite what you might read elsewhere. The Infraction and Felony share a different, shorter 406mm wheelbase chassis optimized for on-road speed runs. The Fireteam’s 422mm wheelbase and Kraton-width geometry make it a fundamentally different animal — more stable, more ground-clearance-capable, and designed for mixed-surface bashing rather than pure tarmac runs.
That wider, longer platform isn’t a compromise. It’s what gives the Fireteam its reputation for high-speed stability and crash resilience that few 6S trucks can match. If you’re new to the brand and want to understand where the Fireteam sits in the range, our complete guide to Arrma covers every model side by side.
Driving Experience
Speed & Acceleration
GPS-verified top speed on stock 12T/50T gearing with a fresh 6S pack sits at around 54 mph — quick by any measure, even if it falls short of the marketed 60+ figure. Arrma includes a 15T speed pinion in the box, and swapping to it bumps real-world speed to a legitimate 61 mph. That’s the number behind the “60+ mph” claim, and it checks out — just note that the speed pinion packaging explicitly warns against off-road use due to heat buildup.
On 4S, the truck runs approximately 38–42 mph depending on battery quality and surface. That’s a great starting point if you’re learning the platform before committing to the full 6S experience. First time I ran it on 6S after spending a pack on 4S, the difference was jarring — not just in speed but in how the truck demanded respect and smooth inputs. The Fireteam on 6S is a different machine entirely.
Acceleration is aggressive and immediate. The Spektrum Firma 4074 motor has zero hesitation, and the 6.26 kg weight keeps all four tires planted hard under full throttle — no power wheelies, no front-end lift. The truck just goes.
Handling
The Fireteam’s 422mm wheelbase and 450mm track width create a level of high-speed stability that routinely surprises people expecting something squirrely. On smooth pavement, it stays planted through long straight-line runs in a way that genuinely inspires confidence at 50+ mph. The low-slung chassis combined with the Kraton-width suspension keeps the center of gravity manageable even though the military body sits taller than a pure on-road shell.
On mixed surfaces — packed gravel, parking lot tarmac, mild grass — the 70mm of ground clearance does real work. The Fireteam handles bumps that would flip a lower-slung truck without drama. I ran it side by side with a friend’s Infraction 6S across a rough parking lot transition and the difference was stark — the Fireteam simply absorbed it where the Infraction pitched. Cornering requires smooth, progressive inputs at speed; sharp steering input above 40 mph will roll it, but that’s true of any 1/7-scale truck at those velocities. Respect the physics and the handling is predictable, teachable, and genuinely fun.
What the Fireteam is not is a big air basher. This is a speed/terrain truck, not a jump machine. The body is tall and the mass is significant — hang time ends painfully if you launch it off anything more than a small ramp.
Durability
The Fireteam has earned a reputation as one of the toughest chassis in the Arrma 6S family. The wide stance and long wheelbase distribute crash energy better than compact trucks, and the aluminum chassis plate handles impact well. The Spektrum Firma drivetrain — motor, ESC, three oil-filled diffs, steel driveshafts throughout — is rated for 6S and holds up to it under normal bashing conditions.
That said, at 54+ mph, any crash is a significant event. The multi-panel body system is the Fireteam’s most vulnerable component: the decorative details (turret, crew figures, guards) break on hard impacts, and the screws that hold the body panels tend to pull through thin polycarbonate without washers. The factory bearings are a known weak point — many owners replace them within the first few packs. The Firma 150A ESC runs warm under sustained 6S load, especially with the speed pinion; lowering motor timing from stock 22.5° to 15° is a widely recommended precaution.
The good news: most of what breaks is cheap and fast to fix, and the underlying platform is genuinely robust.
Known Issues & Honest Criticisms
Body panel screw pull-through is the single most universal complaint from Fireteam owners. The small screws that hold the multi-panel body together lack washers from the factory, and the screw heads pull directly through thin polycarbonate under any real impact. The fix costs almost nothing — add flat washers under every body screw and reinforce attachment points with E6000 adhesive — but it’s frustrating that it’s necessary out of the box.
Factory bearings fail fast. Replacing the stock bearings with quality aftermarket units is considered a day-one upgrade by most experienced Fireteam owners. A full bearing kit runs $15–$25 and it’s an hour well spent before your first run. Check Price on Amazon
ESC heat with the speed pinion. The Firma 150A runs adequately on the standard pinion, but push it hard off-road or with the 15T speed gear and heat becomes a legitimate concern. Reduce motor timing and monitor temps in your first few sessions.
Not versatile terrain-wise. The 70mm ground clearance is better than the Infraction but the Fireteam still wants smooth or semi-smooth ground. Deep grass, loose gravel, and rough off-road kill the experience. If you want genuine off-road capability, look at the Kraton 6S or Notorious. For a full comparison of all-terrain options, our best RC trucks & bashers guide covers the landscape.
It’s discontinued. Arrma has ended production of the Fireteam. Replacement body kits and mechanical parts remain available through Horizon Hobby’s parts system, and the heavy component sharing with the Kraton/Mojave platform means maintenance won’t be a problem long-term — but you won’t be buying a brand new one in two years. Stock is clearing out now at excellent prices, which is the flip side of that reality.
These are real limitations, not dealbreakers. The Fireteam is excellent at what it’s designed to do.
Arrma Fireteam vs Infraction 6S
A common misconception worth clearing up: the Fireteam and Arrma Infraction 6S do not share a platform. The Infraction runs a 406mm wheelbase chassis specifically optimized for on-road speed. The Fireteam’s XLWB aluminum chassis has a 422mm wheelbase with Kraton-width suspension geometry — wider, longer, and designed for more terrain variety.
What they do share is the broader Arrma 6S ecosystem: similar motor and ESC, the same 17mm hex pattern, and much of the internal drivetrain. But their suspension arms, shock towers, chassis plates, and body mounting systems are all different and non-interchangeable.
In practice, the Infraction’s lower, more aerodynamic body gives it a real top-speed advantage — owners routinely see 70+ mph with the right pinion, versus the Fireteam’s 61 mph ceiling. The Fireteam counters with better ground clearance, superior crash stability thanks to its wider stance, and a unique look that the Infraction simply cannot replicate. The Infraction is available in 3S and 6S variants; the Fireteam is 6S only.

Choose the Fireteam if: you want military styling, mixed-surface capability, and maximum high-speed stability. Choose the Infraction 6S if: pure top speed on smooth pavement is the priority and you don’t need the military aesthetic.
Arrma Fireteam vs Felony 6S
Both the Fireteam and the Arrma Felony 6S are Arrma’s street-speed machines, but they appeal to very different aesthetics. The Felony’s low-slung muscle car body is purpose-built for speed run culture — it’s the truck you picture when someone says “RC street racer.” The Fireteam is the truck you picture when someone says “this shouldn’t be going this fast.”
Performance-wise, the Felony has the aerodynamic edge and can push higher top speeds with the right gearing. The Fireteam has the stability edge thanks to its wider track and longer wheelbase. Both are genuinely fast, genuinely capable, and both demand experienced hands at 6S.
The Felony also benefits from a more established aftermarket body scene — Bittydesign, Pro-Line, and others make alternate bodies for it. The Fireteam’s unique multi-panel system has no aftermarket body equivalents.

Choose the Fireteam if: the military look is what drew you in — that’s the whole point of this truck. Choose the Felony if: you want the classic street-bash aesthetic with slightly better aftermarket body support.
Best Arrma Fireteam Upgrades
Better Servo ($30–$100)
The stock Spektrum S652 is a decent metal-geared unit, but it uses a 23T spline — most quality aftermarket servos use 25T, so factor in a new servo horn. A 25kg+ metal gear digital servo dramatically improves steering response and is considered essential for serious 6S running. Adding a glitch-buster capacitor is recommended when upgrading to high-draw servos.

Aluminum Steering Bellcrank ($25–$35)
The stock plastic bellcrank system develops play over time, and the factory servo saver spring absorbs steering input before it reaches the wheels. An aluminum bellcrank with integrated bearings directly replaces the stock unit — the steering precision improvement is immediately noticeable on a truck that does 54+ mph. Compatible with all Arrma 6S models sharing the Kraton steering geometry.

Quality Bearings ($15–$25 full set)
Factory bearings are a known weak point — replace them proactively rather than reactively. A full set of quality aftermarket bearings is the single highest-priority day-one upgrade on this truck.
Check Price — Arrma 6S Bearing Kit on Amazon
RPM A-Arms ($12–$18 per arm)
Because the Fireteam uses Kraton-width suspension arms, it’s fully compatible with RPM’s Arrma 6S A-arm lineup. These offer approximately 30% thicker lower supports and 22% thicker uppers versus stock, and they’re the same proven parts used across Kraton/Outcast V5 and EXB models. Cheap insurance against the most common crash breakage.

Steel Spur Gear ($15–$30)
The stock plastic 50T spur wears under sustained 6S power. A hardened steel Mod 1 50T spur gear is a direct drop-in replacement that’s essentially permanent — one of the cheapest, highest-value upgrades available. Multi-gear combo sets that include the steel spur plus multiple pinion options are available for those who want to experiment with gearing.

Better Tires ($30–$50 set)
Stock tires are functional but not the grippiest available. Road-specific compound tires improve straight-line traction and cornering confidence at speed — worth considering once you’ve put a few packs through the truck on stock rubber.

Replacement Body Panels ($55–$100)
The Fireteam body will eventually need replacing — the decorative details take abuse and the panel screws pull through without washers. Arrma sells the exterior body panel set separately for both colorways. A full replacement including guards and cage components runs $80–$140 depending on how much you need. The flat washer trick extends the life of any replacement set significantly.

FAQ
Q: Is the Arrma Fireteam good for beginners?
No — this is a 1/7-scale 6S truck that reaches 54 mph on stock gearing, and it demands genuine driving experience and spatial awareness at those speeds. Beginners should build their skills first on a manageable 3S truck. Our best RC cars for beginners guide and Arrma Vorteks review are the right starting points; if you want to understand the full Arrma entry-level progression, the Grom series guide is worth a read too. The Fireteam is for experienced drivers who understand exactly what they’re signing up for.
Q: How fast does the Arrma Fireteam go?
GPS-verified at approximately 54 mph on stock 12T/50T gearing with a quality 6S pack, and 61 mph with the included 15T speed pinion on smooth pavement. The “60+ mph” advertised figure requires the speed pinion swap. Actual speed varies with battery quality, surface conditions, and temperature — and the speed pinion is explicitly not recommended for off-road use due to heat buildup in the motor and ESC.
Q: What battery does the Arrma Fireteam use?
Two 3S LiPo packs wired in series for 6S operation, or two 2S packs for a 4S setup. The Fireteam uses IC5 connectors — standard EC5 batteries plug directly in without any adapter needed. The critical dimension when selecting packs is height: stacked 3S packs should each be 32mm tall or less to clear the body and internal roll cage. Budget $80–$120 for a quality pair of 5000–6500mAh 50C packs — Check Price on Amazon — and see our charger guide for 6S-capable charger recommendations.
Q: Is the Fireteam the same as the Infraction?
No — this is one of the most common misconceptions about this truck. The Fireteam runs on the XLWB Mojave platform with a 422mm wheelbase and Kraton-width suspension arms. The Infraction and Felony use a different 406mm on-road chassis. They share the broader Arrma 6S electronics ecosystem and some internal drivetrain components, but the suspension geometry, chassis plate, body mounting, and wheelbase are all different. Bodies and suspension arms are not interchangeable between the Fireteam and Infraction/Felony.
Q: What are common Fireteam problems?
The most universal issue is body panel screw pull-through — add flat washers under every body screw as an immediate fix before the first run. Factory bearings fail early and should be replaced proactively. The ESC runs warm under heavy 6S use with the speed pinion — lowering motor timing from stock 22.5° to 15° is a standard precaution. The stock steering bellcrank develops play over time and benefits from an aluminum replacement. All of these are inexpensive, well-documented fixes that experienced owners address during initial setup rather than waiting for failures.
Conclusion
The Arrma Fireteam is a genuinely unique truck in 2026 — military styling that no other major RC brand has attempted, built on a wide, stable, aluminum platform that earns its durability reputation run after run. It’s fast without being reckless, distinctive without being fragile at the chassis level, and unlike anything else in your lineup or anyone else’s.
It’s not trying to be the fastest truck on pavement, and it’s not a deep off-road machine. It’s a head-turning, 54 mph, mixed-surface speed basher with a look that stops people in their tracks — and at current clearance prices around $350–$430, it’s never been better value. Stock is finite and will not be restocked once it’s gone.
