Overview
The Axial UTB10 Capra 1.9 4WS 4X4 Unlimited Trail Buggy represents the pinnacle of 1/10 scale rock crawling technology, designed specifically for serious enthusiasts who demand the very best performance on the most challenging terrain. This isn't a casual RC car for Sunday drives or overlanding adventures — it's a purpose-built trail buggy engineered from the ground up to conquer technical obstacles, steep hillsides, and complex crawling courses. The Capra has already set the standard for 1/10 scale trail buggies in the UK RC market, and this updated version raises the bar even further with an all-new transmission featuring significantly lower gearing for dramatically improved climbing ability and power delivery.
Whether you're a seasoned rock crawler competing in formal events, a dedicated weekend basher tackling natural terrain, or an enthusiast looking for the most capable ready to run RC crawler available, the Capra delivers uncompromising performance. Every component has been carefully selected and optimised to work in perfect harmony — from the licensed Currie F9 portal axles that increase ground clearance and durability, to the four-wheel steering system that gives you precision control in tight technical sections. This is a brushed electric RC car that doesn't compromise on capability, featuring waterproof Spektrum electronics, robust all-terrain Pro-Line OE tyres, and a chassis design that mirrors full-scale rock crawling competition vehicles.
The Capra comes as a ready to run RC model, meaning it arrives assembled and includes virtually everything you need to get started — a transmitter, receiver, motor, servos, and speed controller are all installed and ready to go. You'll simply need to supply a compatible 2-3S LiPo battery and charger to begin exploring the limits of technical terrain. For UK RC enthusiasts seeking the most authentic and capable trail buggy experience, this Axial model stands alone as the definitive choice in the 1/10 scale category.
Key Features
- Four-Wheel Steering (4WS) System — The Capra's dual steering setup allows you to control both the front and rear axles independently using the third channel button on your included Spektrum DX3 transmitter, giving you the ability to position all four tyres perfectly when navigating obstacles and technical sections. This four-wheel steering advantage is so significant compared to standard two-wheel steering vehicles that it almost feels like having an unfair advantage, and it's essential for serious rock crawling where every inch of manoeuvrability counts.
- Improved Transmission with Lower Gear Ratio — This updated Capra features an exceptionally low final drive ratio of 45.37:1 (with a 6.31:1 internal ratio), which represents a dramatic 45% improvement over the previous model's 31.4:1 ratio. This lower gearing vastly improves climbing ability and power delivery, allowing the buggy to scale steep inclines and power through obstacles that would challenge vehicles with higher ratios.
- Licensed Currie F9 Portal Axles — These professionally engineered portal axles increase ground clearance significantly whilst maintaining the durability needed for extreme off-road use, and they're specifically designed for optimal rock crawling performance with over 45% steering capability. The improved ramp-style third member design also reduces hang-ups on rocks and obstacles, helping you maintain momentum through technical terrain.
- Pro-Line OE Original Equipment Wheels and Tyres — The Capra rolls on officially licensed Pro-Line OE Holcomb 1.9 wheels wrapped in Pro-Line OE Mickey Thompson Baja Pro X tyres, featuring aggressive tread patterns designed specifically for superior crawling traction. Dual-stage open-cell foam inserts with soft outer foam and firm inner foam provide both responsive grip and essential sidewall support when navigating rocky terrain.
- Smooth, Durable 4-Link Suspension — The carefully tuned suspension geometry features fine-tuned linkage and solid axle design that delivers the smooth, flexible, and durable performance essential for technical crawling. Stainless steel suspension links and pivot balls resist corrosion whilst providing precise, reliable connection points, and aluminium oil-filled shock absorbers with threaded, anodised bodies allow you to fine-tune dampening by adjusting spring preload through simple collar rotation.
- Robust Tube Chassis Design — The injection-moulded tubular chassis captures the authentic scale appearance of a genuine rock crawling buggy whilst being optimised for generous suspension travel and tyre clearance. This design philosophy ensures the Capra can articulate fully over obstacles without binding or limiting suspension movement.
- Complete Spektrum Electronics Package — The Capra includes everything needed for advanced RC control: a Spektrum Firma 40A brushed waterproof ESC, Spektrum SR515 DSMR 5-channel receiver, and two Spektrum S683 25T waterproof metal-gear servos for front and rear steering. All electronics feature waterproof and dustproof construction, essential for durability in wet or muddy conditions.
- Spektrum DX3 2.4GHz Smart Transmitter — This included transmitter features exclusive DSMR technology for superior range, response, and interference resistance, and it's fully compatible with the Smart telemetry capabilities of your rig's ESC and receiver. You can even program the DX3 to enable a 5-position rear steer switch for additional tuning capability.
- Metal Universal Joints on Both Axles — The drivetrain features metal universal joints that deliver smooth, efficient action with 45 degrees of steering capability, providing the durability and reliability needed for constant technical crawling.
- Ready-to-Run Brushed Electric Power — The Capra arrives fully assembled with a 540 size 35T brushed motor already installed, delivering an ideal balance between technical crawling ability and sufficient power for challenging terrain. The motor features enlarged cooling ports for extended crawling sessions, and the brushed design offers hassle-free operation without the complexity of brushless systems.
Technical Performance
The Axial Capra represents the engineering pinnacle of 1/10 scale rock crawler design, with every specification carefully calibrated to deliver uncompromising performance on technical terrain. At 442.5mm in length, 272mm in width, and 229mm in height, the Capra maintains a realistic trail buggy scale whilst providing sufficient space for essential mechanical components. Weighing just 2.04 kilograms without battery, the lightweight construction doesn't sacrifice durability or rigidity. The 1/10 scale chassis uses injection-moulded tubular construction that balances weight reduction with the structural integrity required for serious obstacles and technical rock crawling. Ground clearance of 84.65mm (3.33 inches) and a wheelbase of 323mm (12.7 inches) create the geometry needed for extreme articulation without losing stability on technical terrain. The 540 brushed motor paired with the dramatically improved 45.37:1 final drive ratio (6.31:1 internal) and 14-tooth pinion delivers exceptional crawling power whilst maintaining driveline efficiency. The Spektrum Firma 40A brushed waterproof ESC provides reliable power delivery with protection against the elements, whilst the waterproof servo pair ensures steering remains responsive in wet conditions. Battery compatibility extends to 2S and 3S LiPo packs with EC3 or IC3 connectors, giving you flexibility in power selection depending on your terrain and driving style. The front and rear track widths of 225.3mm (8.87 inches) and metal-geared steering servos working in concert with the four-wheel steering system deliver the precision control that separates competitive rock crawlers from standard off-road buggies. The 1.9-inch Pro-Line tyres mounted on scaled Holcomb wheels provide authentic appearance alongside practical traction, with the dual-stage foam inserts offering the exact balance of grip and sidewall support required for extreme technical terrain.

Frequently Asked Questions
- Is the Axial Capra 1.9 suitable for beginner RC enthusiasts? — The Capra is best suited to intermediate and advanced RC enthusiasts who have experience with rock crawling and technical off-road driving. Whilst the ready-to-run format makes it easy to unbox and assemble, the technical complexity of four-wheel steering, the need for careful battery selection, and the demanding terrain it's designed for make it less ideal for complete beginners to the RC hobby. If you're new to RC, starting with a simpler two-wheel steering buggy might be more appropriate before progressing to this level of capability.
- What battery does the Capra 1.9 need? — The Capra requires a single 2-3S LiPo battery with either an EC3 or IC3 connector. A 2S battery will provide a more gentle power delivery suitable for extreme technical crawling, whilst a 3S LiPo will deliver increased speed and power. Battery capacity should be selected based on your intended use, with larger capacity packs providing longer runtime at the cost of increased weight. You'll also need a compatible balance charger to safely charge your chosen battery.
- What makes the four-wheel steering system so important in rock crawling? — Four-wheel steering (4WS) allows you to articulate both the front and rear axles independently, giving you precise positioning of all four tyres when navigating over rocks, through gaps between obstacles, and around technical course markers. In formal rock crawling competitions, this manoeuvrability is essential to avoid losing points from reversing or accidentally touching markers. You control rear axle steering through the third channel button on your DX3 transmitter, and can programme it for different steering patterns to suit various obstacles.
- How does the improved 45.37:1 gear ratio benefit crawling performance? — The updated final drive ratio of 45.37:1 represents a 45% reduction compared to the previous model's 31.4:1 ratio, dramatically lowering the mechanical advantage required to climb steep terrain. This lower ratio translates to increased torque at the wheels, allowing the Capra to scale steeper inclines, power through deeper obstacles, and maintain momentum on technical terrain where a higher ratio vehicle would lose traction or stall. The trade-off is slightly reduced top speed, but for serious rock crawling this compromise is absolutely worth making.
- Are the electronics on the Capra waterproof? — Yes, the Spektrum Firma 40A ESC, SR515 receiver, and S683 steering servos all feature waterproof and dustproof construction, making the Capra suitable for use in wet conditions, muddy terrain, and stream crossing environments. However, it's always good practice to rinse electrical components with fresh water after extensive water exposure and allow them to dry thoroughly.
- Can I programme different steering configurations on the DX3 transmitter? — Yes, the included Spektrum DX3 transmitter is fully programmable. You can set the rear axle steering to full left, centre, and full right through the third channel button, and you can even programme a 5-position rear steer switch for additional tuning capability. This allows you to optimise the steering response for specific obstacles or your personal driving style.
- What is the difference between this Capra and other 1/10 scale trail buggies? — The Capra sets itself apart through several key advantages: the four-wheel steering system provides manoeuvrability that two-wheel steering competitors simply cannot match, the dramatically lower 45.37:1 gear ratio delivers superior climbing ability and power, the licensed Currie F9 portal axles increase ground clearance and durability beyond standard axles, and the professionally engineered 4-link suspension is specifically tuned for technical rock crawling rather than general off-road use. The complete Spektrum electronics package with Smart transmitter compatibility and the authentic scale appearance of the tube chassis complete the package that makes the Capra the industry standard for 1/10 scale trail buggies.
