The Axial UTB18 Capra 4WD RTR brings the ultimate scale trail experience to a versatile 1/18 scale size. Updated with the latest Spektrum electronics, it’s an affordable rig that’s highly capable for adventuring on trails or entering in competition.
The UTB18 Capra 4WD Unlimited Trail Buggy brings the go-anywhere grit of Axial rock crawling rigs to a groundbreaking 1/18 scale size. Easily affordable and fully ready-to-run, the UTB18 enables anyone, with or without RC experience, to enjoy the unlimited scale trail experience even in locations with limited area for crawling. Its proven design is also plenty capable of giving mini competition enthusiasts an immediate edge.
The UTB18 is similar in design to the popular 1/10 scale Axial Capra 1.9 4WD Unlimited Trail Buggy and has a scaled-down Capra tube chassis. Like the larger trail buggy, the UTB18 also has portal axles to provide extra ground clearance for maneuvering. Add in its axle-mounted, low profile 1/10 scale servo for quick, strong steering and the durable 4-link suspension system, and the UTB18 is ready to prove that size has nothing to do with crawling performance.
Plus, this mightiest of mini trail buggies is now updated with the latest Spektrum electronics. In addition to a Spektrum SLT2 2.4GHz radio, the UTB18 comes with a Spektrum 2-in-1 ESC/receiver unit, Spektrum 2S Smart G2 LiPo battery, and Spektrum Smart USB LiPo battery charger. It’s even easier to use than before, and the value of the RTR package is better than ever.
Perfect for indoor and outdoor crawling, the UTB18 delivers impressive performance on the rocks, climbing rock ledges, flexing over obstacles, and squeezing through tight notches. Officially licensed Nitto Trail Grappler M/T tires mounted to officially licensed Raceline Monster wheels give it the grip to conquer rocky trails, rough dirt tracks, and most other off-road surfaces. Body panels with licensed livery, helmeted driver and passenger figures, LED lights and more combine for realistic scale looks to match its crawling capabilities.
With its distinctive Capra trail buggy looks, high-end performance, and exceptional value, the fully assembled and equipped Axial UTB18 is an ideal RC crawler for all ages and skill levels. Get yours and add some adventure to your life!
In addition to a Spektrum SLT2 2.4GHz radio, the fully assembled and equipped UTB18 now also comes with a Spektrum 2-1 ESC/receiver unit, Spektrum 2S Smart G2 LiPo battery, and Spektrum Smart USB LiPo battery charger. Everything you need to start crawling is included in the box.
Similar to the popular Capra 1.9 Unlimited Trail Buggy but in 1/18 scale, the UTB18 enables anyone to afford an easily portable, highly capable crawler that delivers the ultimate scale trail experience even in locations with limited area for crawling.
By reproducing the proven 1/10 scale Capra tube chassis design in 1/18 scale, Axial gives the UTB18 the same realistic trail buggy looks as well as optimum clearance over rugged terrain.
The UTB18 includes portal axles that increase ground clearance at the differential and deliver the best crawling performance.
Like the setups used by most competition crawlers, the UTB18 has an axle-mounted servo that contributes to a lower center of gravity and allows better steering control in full articulation.
Axial universals provide smooth action and 45 degrees of steering angle for an efficient, higher performing drivetrain. The universal is made of machined steel for durability.
Axial has fine-tuned the UTB18 suspension geometry to provide the best crawling capabilities. The lower links are stainless steel for increased performance and durability.
Nitto Trail Grappler M/T tires on Raceline Monster black composite wheels find a secure grip on dirt, rocks, and all other off-road trails, providing realistic scale looks and serious trail performance.
The interior inside the licensed livery body panels features helmeted driver and passenger figures plus other realistic details that add to the UTB18 rig’s authentic 1/18 scale crawler looks.
