FairRC Scale Accessories and Parts — What to Buy to Upgrade Your Crawler
Buying an RC crawler is the start of the process, not the end. Whether you are running an FMS FCX24, an FCX18, or a FairRC Mod RTR, the parts and accessories ecosystem around these platforms is where the hobby gets genuinely interesting — and where the visual and performance character of your build becomes your own. FairRC has built one of the most complete accessories catalogues for the FCX24 and FCX18 platforms, covering everything from performance tyres and beadlock wheels through to 3D-printed resin body parts, scale accessories and brushless system upgrades.
This guide covers the accessories worth knowing about, organised by category and purpose. Every product is available directly from FairRC's parts catalogue.
BATRAZZI Tyres — The Single Most Impactful Upgrade
BATRAZZI is FairRC's in-house performance tyre and wheel brand, and it is the first upgrade most FCX18 and FCX24 owners make. The stock tyres on both platforms are capable, but BATRAZZI compounds and tread patterns are specifically developed for the weight and torque characteristics of micro crawlers – the difference in grip on loose terrain, wet surfaces and textured indoor surfaces is immediate and measurable.
The current BATRAZZI range covers multiple tread patterns and sizes for both platforms. The Precipice 1.9" M/T tyres are the most popular all-round choice — a mud terrain tread in a soft compound that works well on both indoor and light outdoor surfaces. The All-Terrain Track Set for FCX24/FCX18 is the most dramatic option — a full rubber track conversion that transforms the visual character of the crawler entirely and delivers outstanding traction on soft surfaces.
Beadlock Wheels — Visual Impact and Tyre Security
Beadlock wheels serve two purposes on a micro crawler: they clamp the tyre bead mechanically, preventing the tyre from de-beading under torque or side-loading, and they dramatically improve the scale appearance of the wheel assembly. The difference between stock plastic wheels and a set of CNC-machined aluminium beadlocks is one of the most visible single upgrades available.
BATRAZZI's beadlock range for the FCX18 and FCX24 covers multiple finishes — gunmetal, silver, and black — in 1.0" (FCX24) and 1.2" (FCX18) sizes. The 1.9" Aluminium D-Hole Beadlock Wheels for the FCX18/FCX24 are the current reference option, CNC-machined and available in a gunmetal finish. Pairing beadlocks with BATRAZZI Precipice tyres is the standard starting upgrade for either platform.

3D-Printed Resin Parts — Scale Detail That Changes the Look
FairRC's in-house 3D-printed resin parts range is one of the most distinctive aspects of their accessories catalogue. These are not rough-printed hobbyist parts — they are production-quality resin components designed specifically for the FCX18 and FCX24 platforms, with the same fit precision as the factory bodywork.
The range currently includes:
- Front bumper for FCX18 Land Cruiser — a scale-accurate replacement bumper with improved ground clearance geometry and a more aggressive visual profile than the stock item.
- Rock sliders for FCX18 LC80 — side protection that adds scale realism and genuine chassis protection on technical terrain.
- Taskmaster Flatbed for FMS K10 and EazyRC Glacier — a full flatbed replacement that converts the standard pickup into a flatbed configuration. One of the most visually transformative single parts available for the K10 platform.
- Truck Camper Shell for Tacoma — a scale camper shell for the FCX24M Tacoma that adds a completely different character to the vehicle.
- Front bumpers, roof racks and body accessories across multiple FCX18 and FCX24 subjects.

BATRAZZI Brushless System — Performance Upgrade for FCX18 and FCX24
For FCX18 and FCX24 owners wanting a meaningful performance upgrade, the BATRAZZI Brushless System replaces the stock motor and ESC with a higher-efficiency brushless drivetrain. The verified product is the BATRAZZI Ctrl Frk 3200KV Brushless Outrunner Motor, Receiver and FOC ESC Set, available for both FCX18 and FCX24. The benefits are consistent: smoother throttle response at low speeds (critical for technical crawling), lower heat generation on extended runs, and more usable torque. Our BATRAZZI brushless systems guide covers the options and installation considerations in detail.

Scale Accessories — Details That Earn a Second Look
Beyond performance upgrades, FairRC stocks a range of scale accessories that add visual detail without affecting performance: spare tyre mounts, interior detail parts, scale fuel cans, hi-lift jack replicas, recovery boards and soft goods. These are the parts that separate a stock RTR from a build that rewards close inspection. Combined with a set of beadlocks and a BATRAZZI tyre, a few carefully chosen scale accessories can transform a factory vehicle into something that looks genuinely personalised.

Platform Parts and Spares
For builders who break things — which is everyone, eventually — FairRC's parts catalogue covers CVD axle sets, servo mounts, servo horn sets, shock absorbers, anti-roll bars, steering arms and axle hardware for both the FCX18 and FCX24 platforms. Worth noting: many FCX24 and FCX18 parts are cross-compatible between the two platforms, which simplifies spares sourcing if you run both scales. FMS Hobby also carries a direct spare parts catalogue for both platforms.

The Upgrade Order That Makes Sense
If you are starting from a stock FCX18 or FCX24 and want to upgrade progressively, the sequence that delivers the most noticeable improvement per step is: beadlock wheels and BATRAZZI tyres first, then 3D-printed body parts for visual character, then the BATRAZZI Brushless System if you want more performance, then scale accessories to finish. Each step is independently reversible, and none requires permanent modification to the base platform. The FairRC Mod RTR vehicles — covered in our FairRC Mod RTR Explained article – are essentially this upgrade sequence applied at the factory, which is worth considering if you are building a new crawler rather than upgrading an existing one.
