Whether you're a seasoned RC enthusiast looking to add a capable mini crawler to your collection, or a newcomer discovering the thrilling world of RC trail buggies for the first time, this fully assembled ready to run RC car delivers exceptional performance without requiring any additional purchases or assembly. At just 1/18 scale, the UTB18 Capra 4WS dominates challenging indoor and outdoor trails with professional-grade features typically found on much larger and more expensive models.
This ready-to-run RC crawler climbs to the summit of the mini RC crawler category by combining four-wheel steering technology, portal axles with high ground clearance, officially licensed Mickey Thompson Baja Pro X tyres, and a comprehensive Spektrum electronics package that sets a new benchmark for value and capability. The UTB18 Capra 4WS makes it easy to add adventure to your life almost anywhere, whether you're navigating rocky trails in your garden, conquering indoor obstacle courses, or exploring challenging terrain in locations with limited space.

The scaled-down Capra tube chassis delivers realistic trail buggy styling with helmeted driver and passenger figures, working LED headlights, a light bar, and forward-facing rock lights for crawling after sunset. Available in two striking paint schemes—a grey cage with blue body panels featuring licensed King Shocks livery, or a black cage with yellow body panels featuring licensed Mickey Thompson Tire livery—this is a ready-to-run RC vehicle that looks as impressive as it performs.
Key Features
- Four-Wheel Steering System — The UTB18 Capra 4WS features independent four-wheel steering with three selectable modes (no rear input, mirrored rear input, and crab crawl mode) controlled from the included Spektrum SLT3 transmitter, delivering unmatched maneuverability on rock ledges, over obstacles, and through tight spots that would challenge larger crawlers.
- 4WD Drivetrain — The four-wheel drive system combined with the 4WS steering capability creates exceptional terrain-conquering ability, allowing the rig to navigate and climb challenges that would be impossible for two-wheel drive alternatives.
- Portal Axles with Currie F9 Housing — High-clearance portal axles provide both scale authenticity and maximum ground clearance (1.7 inches/43mm) for navigating rougher, tougher trails whilst maintaining the realistic proportions that make this crawler so visually appealing.
- Officially Licensed Mickey Thompson Baja Pro X Tyres — Mounted on Pro-Line Holcomb Internal Bead-Loc wheels, these aggressive-stance licensed tyres deliver the grip needed to conquer rocky trails, rough dirt tracks, and most other indoor and outdoor crawling surfaces.
- Advanced 4-Link Suspension Geometry — The 4-link suspension design provides smooth, consistent articulation without the bump steer found in inferior 3-link designs, with stainless steel lower links for increased performance and durability.
- Stand-Alone Spektrum Electronics — The individual Spektrum Firma 25A brushed ESC and 5-channel SR515 dual protocol receiver accommodate future transmitter upgrades and additional lighting options, giving you flexibility to expand and customise your setup.

- LED Lighting Package — Working LED headlights, light bar, and forward-facing rock lights highlight the 1/18 scale realism and enable crawling during low-light conditions, adding to both aesthetics and functionality.
- Realistic Interior Details — The licensed livery body panels feature helmeted driver and passenger figures with realistic detailing that enhances the authentic 1/18 scale crawler appearance.
- All-Metal Universals — Durable all-metal universal joints throughout the drivetrain ensure longevity and reliability under the stresses of trail crawling.
Technical Performance
The Axial UTB18 Capra 4WS delivers impressive performance through its carefully engineered technical specification. Powered by a Dynamite Tazer 37T 380-size brushed motor, the rig achieves capable off-road performance whilst maintaining efficiency through a 44.88 gear ratio with a 13-tooth pinion and 40-tooth spur gear in 48-pitch specification. The Spektrum Firma 25A brushed ESC provides reliable speed control with forward and reverse capability, whilst remaining lightweight at just 1.8kg (4.0 lbs) overall. The drivetrain utilises a spool differential for consistent power delivery across all four wheels. The 9-inch (229mm) wheelbase combined with the compact 1/18 scale dimensions (434mm length, 236mm height, 206mm width) creates a vehicle perfectly proportioned for navigating tight spaces that larger crawlers cannot access. The Spektrum Smart 650mAh 2S 30C 7.4V LiPo battery with IC2 connector provides over 30 minutes of uninterrupted adventure on a single charge, whilst the included Spektrum S10 G2 Smart USB-C charger allows rapid, intelligent recharging. Two Spektrum S664 25T steering servos deliver quick, powerful steering response with the axle-mounted design ensuring precise control. The plastic multi-piece tube frame chassis provides lightweight construction whilst maintaining the scale authenticity of the iconic Capra design. Coil-over oil-filled shocks with solid axles ensure smooth articulation across uneven terrain. The 12mm wheel hex size accommodates a wide range of optional wheel and tyre combinations for future upgrades. The complete package arrives fully assembled and waterproofed, requiring only battery charging before hitting the trails—no assembly, no technical knowledge required.

Frequently Asked Questions
- Is the Axial UTB18 Capra 4WS suitable for RC crawling beginners? — Yes, absolutely. This is an ideal entry point into RC crawling. The ready-to-run design means there's no complicated assembly or electronics setup—simply charge the battery and drive. The four-wheel steering makes the rig extremely forgiving and easy to manoeuvre, whilst the proven Capra design ensures consistent, predictable performance that builds driver confidence.
- What makes four-wheel steering better than traditional two-wheel steering on a trail crawler? — Four-wheel steering dramatically improves maneuverability by allowing the rear wheels to steer in addition to the front wheels. The three selectable steering modes let you choose optimal handling characteristics: standard mode for conventional driving, mirrored mode where rear wheels mirror front input for tighter cornering, and crab crawl mode where all four wheels point the same direction for lateral movement through narrow obstacles. This capability alone lets the UTB18 Capra 4WS navigate spaces and terrain that would stymie larger crawlers.
- What battery does the Axial UTB18 Capra 4WS need and how long does it run? — The UTB18 Capra 4WS comes with a Spektrum Smart 650mAh 2S (7.4V) LiPo battery with IC2 connector, which provides over 30 minutes of continuous crawling on a single charge. The Spektrum S10 G2 Smart USB-C charger is included and offers intelligent automatic charging—simply connect the battery and it handles the rest. The 2S LiPo format is the ideal balance between runtime, power delivery, and safety for this 1/18 scale vehicle.
- How does the UTB18 Capra 4WS compare to other 1/18 scale ready-to-run crawlers? — No previous 1/18 scale RTR mini crawler has offered this combination of features and value. The four-wheel steering system is unique in this category, the portal axles deliver exceptional ground clearance (1.7 inches), the 4-link suspension provides superior articulation compared to 3-link designs, the stainless steel lower links ensure durability, the licensed Mickey Thompson tyres and Pro-Line wheels deliver authentic appeal and genuine crawling grip, and the Spektrum electronics package is professional-grade. This is a crawler that genuinely outperforms some larger 1/10 scale models.
- Can I upgrade the electronics or add more lighting to the UTB18 Capra 4WS? — Yes, the stand-alone Spektrum Firma 25A ESC and 5-channel SR515 dual protocol receiver are specifically designed to accommodate future upgrades. The five channels provide capacity for additional lighting circuits, rock lights, light bars, and LED underglow, whilst the dual protocol receiver can work with higher-level Spektrum transmitters like the DX series for enhanced control options. Many Axial UTB18 option parts are already available from authorised dealers.
- Is the Axial UTB18 Capra 4WS waterproof for outdoor crawling? — Yes, the vehicle features waterproof electronics enabling confident operation in wet outdoor conditions, from muddy trails to shallow water crossings. The sealed ESC, receiver, and sealed motor design mean you can tackle challenging natural terrain without weather-related concerns.
- What is the wheelbase and overall size of the UTB18 Capra 4WS? — The 9-inch wheelbase (229mm) combined with overall dimensions of 434mm length, 236mm height, and 206mm width make this an extremely compact crawler perfect for indoor crawling spaces, garden exploration, and locations where larger 1/10 scale rigs won't fit. Despite the compact dimensions, the portal axle design ensures 1.7 inches (43mm) of ground clearance for impressive obstacle navigation.
- What transmitter comes with the UTB18 Capra 4WS and can I use a different one? — The included Spektrum 3-Channel SLT3 2.4GHz transmitter has dedicated buttons for selecting the three steering modes, making it perfectly matched to this vehicle. The dual protocol receiver can accept signals from other Spektrum 2.4GHz transmitters including the DX series, allowing future transmitter upgrades if desired.
