FMS FCX18 II Ford Bronco 2021 — 160mm Chassis, Scale Detail & BATRAZZI Upgrade Guide
The FMS FCX18 II Ford Bronco 2021 brings the sixth-generation Bronco into the compact 1:18 crawler world with a shorter 160mm wheelbase, a low-centre-of-gravity FCX18 II chassis and a strong emphasis on licensed scale detail. It is not simply another body placed on the existing FCX18 formula: the Bronco combines the newer FCX18 II architecture with a hard-shell body, functional lighting, licensed BFGoodrich KO3 tyres and NOMAD wheels, creating a crawler designed to work as both a trail vehicle and a highly detailed scale model.
The Bronco arrives as an RTR brushed model and sits alongside the longer-wheelbase FCX18 II Ford F-100 rather than replacing it. The key difference is proportion. The Bronco's 160mm wheelbase creates a much more compact platform than the 199mm F-100, giving the new model its own character on tight trails while preserving the two-speed drivetrain, portal-style crawler philosophy and upgrade potential that make the FCX18 family interesting.

Why the 160mm Wheelbase Changes the FCX18 II Formula
The most important number in the specification sheet is arguably not the motor, battery or tyre diameter.
It is the 160mm wheelbase.
The FCX18 II Ford F-100 uses a much longer 199mm wheelbase, giving it the proportions and stability expected from a scale pickup truck. The Bronco compresses the same basic FCX18 II philosophy into a shorter SUV platform.
That changes how the vehicle fits into the range.
A shorter wheelbase can make a compact crawler easier to place through tight turns and technical obstacles, while the LCG chassis keeps the major drivetrain components mounted low in the vehicle.
The result is not simply an F-100 with a different shell. The physical relationship between the axles, body and chassis is different enough to make the Bronco its own platform choice.
For a detailed look at the longer truck, see the FMS FCX18 II Ford F-100 RTR Brushed Guide.
Official Ford Bronco Licensing Goes Beyond the Badge
Scale licensing matters most when it changes the whole model rather than simply adding a logo.
The FCX18 II Bronco reproduces the sixth-generation 2021 Bronco with a hard-shell body carrying the recognisable wide grille, BRONCO badging, round headlights, front and rear bumpers, side mirrors, handles, wipers, running boards, roof rack, tow hooks and a full-size spare wheel on the rear.
A moulded interior continues the scale treatment inside the body.
That level of detail makes the model relevant to two different kinds of buyer: the crawler driver interested in the FCX18 II platform and the scale enthusiast who wants the finished vehicle to look convincing when it is not moving.
The Spare Tyre Is Functional, Not Just Decoration
One of the smaller but more interesting details is the rear-mounted spare tyre.
FMS specifically describes it as functional rather than a purely decorative moulding.
That fits the overall design philosophy of the Bronco particularly well. A scale crawler becomes more convincing when apparently functional exterior components are not simply representations built into the body shell.
Licensed BFGoodrich KO3 Tyres and NOMAD Wheels
FMS has continued the licensing approach at wheel level.
The Bronco uses officially licensed BFGoodrich KO3 tyres together with licensed NOMAD wheels, reinforcing the modern off-road identity of the sixth-generation vehicle.
The stock tyre size is approximately 58 × 19 mm, which is important when considering aftermarket combinations. Changing wheel offset, tyre diameter or added brass weight affects more than appearance; it can alter steering clearance, gearing load, stability and the overall stance of the crawler.
Magnetic Quick-Release Body — More Than Convenience
The Bronco uses eleven magnets to secure the body to the chassis.
That eliminates the traditional visible body clips and allows tool-free body removal.
More interestingly, integrated magnetic contacts connect the lighting system automatically when the body is installed.
That means access to the battery and chassis does not require manually disconnecting and reconnecting a separate body-light wiring plug every time the shell is removed.
For a vehicle that is likely to be upgraded repeatedly, that is an important quality-of-life improvement.
Full Lighting System
The magnetic body connection also supports a more complete lighting setup than a simple pair of always-on headlights.
FMS lists headlights, tail lights, turn signals, brake lights and reverse-light functionality within the integrated system.
On a highly detailed modern Bronco body, lighting contributes significantly to the scale effect, particularly during slower trail driving where the body and exterior detail remain clearly visible.
Two-Speed Transmission — Crawl or Trail
The mechanical two-speed transmission remains one of the strongest practical features of the FCX platform.
Low gear gives the driver a much deeper reduction for precise crawling and controlled climbs. High gear provides more wheel speed for ordinary trail driving and moving between obstacles.
The official ratios are 94.2 in low gear and 17.2 in high.
That spread is useful because a scale crawler does not always need to behave like a dedicated competition crawler. A Bronco is just as likely to spend time driving along a trail as it is negotiating one difficult obstacle.
180 Brushed Power System — Why FMS Kept It Simple
The Bronco launches with a 180 brushed motor and an integrated FMS-R3D-BS receiver/ESC system.
For this particular model, brushed power is not necessarily a weakness.
The vehicle is positioned as an RTR trail and crawler platform, where smooth low-speed behaviour, straightforward electronics and predictable control matter more than outright speed.
It also creates a clean upgrade decision later. A buyer can first learn the stock chassis and decide whether the existing power system actually limits the way the vehicle is being used before changing motor and electronics.
Upgrade principle: drive the Bronco in stock form first. The FCX18 II already includes metal drivetrain and suspension components, a two-speed transmission and licensed tyres. Upgrade only when you know whether your priority is scale appearance, steering precision, lower centre of gravity or outright crawling performance.
Metal Construction Where It Matters
“Metal construction” in this case does not mean the entire vehicle is metal.
FMS uses metal components through important areas of the chassis, including the frame rails, suspension links, steering rods, geartrain, servo gears and oil-filled shocks.
That gives the Bronco a stronger mechanical base before the aftermarket catalogue even enters the picture.
It also means BATRAZZI upgrades should be treated as tuning choices rather than mandatory fixes for an unfinished platform.
Stock Bronco vs Upgrade Build — What Should You Change First?
FairRC Tube Light Bumper — The Most Bronco-Specific Upgrade
FairRC has already released a 3D-printed tube light bumper set for the new FCX18 II Bronco, covering both front and rear.
This is different from a generic chassis upgrade because it changes the visual identity of the Bronco itself.
A tube-style bumper pushes the build towards a modified modern trail-rig look while remaining consistent with the full-size Bronco's aftermarket culture.

BATRAZZI Brass 7mm Wheel Hex Hub Adapters
BATRAZZI's brass 7mm wheel hex adapters are designed specifically for FCX18 II stock axles and are available in standard and extended versions.
The important effect is not simply replacing one material with another.
Brass adds mass at a very low point on the vehicle, while the two thickness options allow the track width to be adjusted slightly.
That makes them useful when a wheel and tyre change creates a clearance issue or when the goal is to add modest low-mounted weight without radically altering the chassis.

BATRAZZI Brass Brake Disc Upgrade
The CNC brass brake-disc set combines two kinds of modification that work particularly well on a scale crawler.
Visually, the discs add mechanical detail behind the wheels.
Functionally, the brass introduces approximately 5g per piece of unsprung mass at a low point in the chassis.
That makes the upgrade more interesting than purely decorative brake hardware, particularly for a build that is intended to crawl rather than simply sit on display.

Precipice 1.0-Inch M/T Tyres
The BATRAZZI 60 × 23.5mm Precipice tyres are larger than the stock Bronco's 58 × 19mm tyres.
That immediately makes them a meaningful tuning choice rather than a cosmetic replacement.
The additional diameter and width can change ground clearance, tyre contact, stance and body clearance. Before fitting them, check how the extra dimensions interact with the Bronco's arches and chosen wheel offset.

Revolver Beadlock Wheels
The BATRAZZI 1.0-inch Revolver beadlocks provide a more obviously modified look than the stock licensed NOMAD wheels.
This is therefore a choice between two different build philosophies rather than a simple “better” wheel.
Keep the stock NOMAD setup if the priority is maintaining the licensed Bronco appearance. Move towards BATRAZZI beadlocks if the aim is to create a more personalised crawler with additional tuning options around wheel weight, tyre choice and stance.

Arachna Beadlocks — Modern Styling for a Modern Bronco
The Arachna wheel has a much more contemporary multi-spoke appearance than a traditional steel-style crawler wheel.
That makes it particularly appropriate for the sixth-generation Bronco if the build direction is modern modified off-roader rather than retro trail truck.
The wheels use CNC-machined aluminium and incorporate a brass clamping ring, adding low-mounted mass while retaining an aluminium outer structure.

Steering Upgrades — Do Them for a Reason
FairRC's FCX18 II catalogue now includes aluminium and brass steering links, servo horns, servo mounts and complete steering upgrade combinations.
The temptation with a new crawler is to replace every visible plastic component immediately.
That is rarely the most useful approach.
Aluminium steering parts make sense when increased rigidity and durability are the priority. Brass alternatives add those qualities together with additional front-end mass.
The decision should therefore depend on what you want the Bronco to do, not simply on which parts exist.

Recommended Upgrade Paths
| Build Direction | Recommended Starting Point |
|---|---|
| Factory Scale Bronco | Keep the licensed KO3 tyres and NOMAD wheels. Add only subtle details or the Bronco-specific tube bumper. |
| Scale Trail Build | Tube bumpers, modest brass weight and carefully chosen tyre upgrades while preserving realistic proportions. |
| Technical Crawler | Low-mounted brass, steering improvements, wheel/tyre tuning and careful attention to centre of gravity. |
| Modern Custom Bronco | Arachna or Revolver beadlocks, aftermarket tyres and a more aggressive bumper treatment. |
| Incremental Build | Drive stock, identify one limitation, change one system and test again before adding the next upgrade. |
FCX18 II Bronco vs FCX18 II F-100
| FCX18 II Bronco | FCX18 II F-100 |
|---|---|
| 160mm wheelbase | 199mm wheelbase |
| Compact modern SUV proportions | Long-wheelbase pickup proportions |
| Sixth-generation Ford Bronco body | Classic Ford F-100 body |
| Licensed KO3 tyres and NOMAD wheels | Different stock wheel/tyre identity depending on version |
| Strong fit for tight scale trails | Longer stance and pickup-truck presence |
| Brushed launch configuration | Brushed and brushless configurations available |
The two trucks therefore make more sense as complementary FCX18 II platforms than as direct replacements for one another.
If you prefer the longer pickup chassis, see our FCX18 II Ford F-100 Brushless Guide and FCX18 II F-100 Brushed Guide.
Where the New Bronco Fits in the Wider FMS Range
The FCX18 family already covers classic SUVs, pickups and multiple wheelbase concepts. The new Bronco gives the FCX18 II chassis a compact modern SUV application rather than simply extending the existing F-100 line.
That matters because choosing between FCX18, FCX18 II and FCX24 increasingly comes down to desired scale proportions, wheelbase, body style and upgrade path rather than a simple hierarchy of “better” platforms.
Our FMS FCX18 vs FCX24 vs FCX24M Guide explains those platform differences in more detail.
FairRC + FMS + BATRAZZI — Why This Launch Makes Sense
The Bronco is also a good example of the relationship that now exists between FMS, FairRC and BATRAZZI.
FMS provides the licensed RTR platform.
FairRC provides the retail route, platform-specific accessories and customisation ecosystem.
BATRAZZI adds wheels, tyres, steering components, brass parts and other hardware that can move the same base vehicle towards a different use case.
That is more useful than treating every upgrade as something the stock model is missing.
The real value is choice.
For a deeper look at that ecosystem, see FairRC's New Direction — Stock FMS, Custom Mods & the BATRAZZI Build Ecosystem.
Final Verdict
The FMS FCX18 II Ford Bronco 2021 is one of the more logical additions to the second-generation FCX18 platform because it does not simply repeat the long-wheelbase F-100 formula.
The 160mm wheelbase gives the chassis a genuinely different physical character, while the modern sixth-generation Bronco body brings a strong combination of hard-shell scale detail, functional lighting and officially licensed Ford, BFGoodrich and NOMAD elements.
Underneath, the two-speed transmission, solid axles, 180 brushed power system and extensive use of metal chassis and drivetrain components give the Bronco enough mechanical substance to be enjoyed in stock form.
That point matters.
There is already a substantial BATRAZZI ecosystem waiting for the FCX18 II, but the best upgrade path is not to install everything at once. The Bronco is more interesting when it becomes a deliberate build: keep it factory scale, create a realistic trail rig, add low brass for crawling, or use wheels and tyres to turn it into a modern custom off-roader.
The combination of compact proportions and a broad upgrade path makes the new Bronco particularly appealing for anyone who likes the FCX18 II engineering but wants something shorter and more SUV-like than the F-100.
