TRX4 Scale & Trail Crawler

Originally introduced in 1966 as a 4x4 compact SUV, the Ford Bronco matured as a full-size truck in the late 1970s, cementing its status as a rugged off-roader. Traxxas honors the classic 1979 Ford Bronco with this beautifully detailed and faithful reproduction mounted on the incredibly capable TRX-4 chassis. From the chrome wheels and bumpers to the gorgeous Sunset or red graphics, the TRX-4 recaptures the Bronco’s iconic era with the toughness and technology that could only come from Traxxas.

Officially Licensed Ford Bronco Body: 

• Scale details: grill, chrome bumpers, side mirrors, chrome side trim, and wipers
• Clear front and side windows
• Authentic decal sheet
• Full Nylon composite wheel wells and floor pans
• Additional scale accessories sold separately

Remote Locking Differentials 
Traxxas gives you the versatility to lock and unlock the front and rear differentials to suit your driving needs directly from your transmitter. Leave the differentials unlocked for relaxed driving on the trail with smooth, tight turning and better handling at high speeds. When the trail gets technical, lock the front and rear differentials, or just the front, for superior grip over extreme terrain. This patented design has been proven rugged and capable in the Traxxas Summit. Sleeved micro cables control the differential action for scale appearance, without limiting the huge suspension articulation. 

Hi/Low Range Transmission 
When the going gets tough, use your transmitter to shift into low range for incredible 4-wheel drive pulling torque. Shift into high range for blasting down the trail. The plush suspension design absorbs rough terrain with ease and delivers outstanding scale appearance. Unmatched versatility makes the TRX-4 Scale and Trail Crawler adaptable to just about any situation or driving style.

Waterproof 
Traxxas was the first to bring you fully waterproof RC vehicles years ago with their innovative designs. The TRX-4 Scale and Trail Crawler is fully waterproof for how you like to really play, not “splash resistant.” There is a big difference. Traxxas’ patented innovation gives you the freedom to tackle creeks, snow, and mud without worrying about water in your electronics.

Torque Twist Eliminated 
The portal axles use gear reduction right at the wheels that dramatically reduces undesirable torque twist. Total axle gear reduction is over twice non-portal designs. The Titan 550 motor torque is translated into straight, powerful, forward motion, rather than wasted energy twisting your rig right off the rocks.

The Power of Portals 
The TRX-4 Scale and Trail Crawler is equipped right out of the box with Traxxas' game-changing portal axle set. Portal axles lift the truck at the wheels for huge center pumpkin ground clearance. In order to achieve the same clearance with straight axles (and not get stuck), your tires would have to be over an inch taller than the TRX-4's tires. Straddling boulders with ease, the TRX-4 chassis definitely takes the path less traveled and simply leaves all the others behind.

Improved Geometry 
Portal axle geometry raises the axle link mounts and center driveshaft, greatly reducing critical driveshaft and suspension link angles. This means less strain on the driveshafts, and the higher suspension links provide greater clearance with less scraping and dragging across the rocks. The steering drag link and tie rod are also raised up and out of harm's way.

Rigid Steel Frame 
A heavy-duty formed-steel ladder frame with molded cross members creates an extremely rigid backbone that lets the suspension do the work it was designed to do. You’ll feel the difference on trails where the elimination of chassis flex allows for precise wheel placement when navigating technical terrain.

Scale Detail 
The TRX-4 Trail and Scale is being shown with the legendary Land Rover Defender body, complete with exciting scale details for an authentic 4-wheelin’ experience. Traxxas included a functional spare wheel and tire, an off-road jack, and spare fuel canisters. Secure your trail gear in the included roof basket. There’s even a snorkel for taking the waterproof TRX-4 through creek crossings. The rugged bumpers provide clearance and protection and are equipped with recovery D-rings. The front bumper is designed to be compatible with many popular off-road accessories.

Aluminum GTS Shocks 
Oil-filled coil-over GTS shocks were created exclusively for the TRX-4 chassis. These silver-anodized aluminum units deliver silky-smooth damping performance and feature threaded shock bodies for easy ride height adjustments. The convincing scale realism looks great and they perform even better with an O-ring cap seal and dual X-ring shaft seals.

Metal Gear Digital Servo 
A full-metal gear digital servo gives you the durability and steering authority you need to confidently and reliably power through tough situations.

Cruise Control 
The Traxxas TQi radio system is equipped with cruise control for long-distance treks. Set your speed using the transmitter and then use the multi-function knob to fine-tune it faster or slower to precisely match the pace of your caravan of trail explorers. Cruise control makes it easy and comfortable for the TRX-4 Scale and Trail Crawler to be your companion for hours of driving fun and exploration.

3S Power System 
The XL-5 HV electronic speed control brings 3S LiPo capability for stronger, more efficient running. Updated speed control profiles have been added for smooth and precise control. A Trail profile facilitates smooth driving for most of your adventures, while a Crawl profile introduces hill hold and instant reverse for extremely technical courses. Either will help you navigate obstacles with ease, right from the start. Long run times, up to 2 hours, are possible with a Traxxas 3S 5000mAh iD LiPo battery pack!

Canyon Trail 1.9 Tires 
The 1.9 Canyon Trail tires and tuned foam inserts are super-soft and grippy to deliver superior bite on rocky surfaces with convincing scale realism. The 12mm steel hex drive makes the TRX-4 chassis compatible with popular 1.9 wheel and tire combinations.

Traxxas Tough 
Leave the tools in the bag! The Traxxas TRX-4 chassis is built to handle the rigors of remote locations and all-day driving fun. The foundation begins with a pair of 1.5mm thick steel frame rails. Large diameter steel links and heavy-duty, extra-wide rod ends keep the suspension firmly mounted. Hardened steel CV-style half-shaft joints are ultra reliable, while the brushless-ready steel portal axle and transfer case gears are smooth and quiet. Traxxas’ composite materials have been refined over three decades for the ultimate in strength and durability.

Axial SCX10 III - Portals, Dig, 2-Speed & Jeep Wrangler JL Body  

The Axial SCX10 III Jeep JL Wrangler incorporates the key components that have made the Axial SCX10 series successful - but takes realism and detail to a higher level. The SCX10 III includes a replica V8 engine to house the front-mounted 540 motor. It's mated to a realistic transmission housing and transfer case, just like a 1:1 vehicle.

The unique and versatile transmission can be built in several ways. If using a 3-channel radio, you can set it up with a third-channel DIG function that lets you lock the rear axle from the transmitter for front wheel drive and a tighter turning radius. Another 3-channel option is to set up the vehicle with a two-speed transmission to select between high and low speeds. To have access to the two-speed transmission and DIG function simultaneously, just add another servo and use a radio with at least four channels!

The SCX10 III Jeep JL Wrangler kit features portal axles to improve performance by increasing the ground clearance at the pumpkin, while reducing torque twist. Its standard battery tray accepts full-size standard LiPo or NiMH packs. There's also space on the side rails for drivers who prefer "shorty" packs. Inner fenders and floor sides hide the internal components that hinder the scale look.

To top off the chassis, the kit comes with a clear Jeep Wrangler Unlimited four-door body that's ready for finishing however you like. Scale details include a roll cage, front hood vents and cowl, windshield wipers, mirrors, door handles and more, plus a detailed interior. New taller and wider, officially licensed Nitto Trail Grappler tires on 3-piece licensed KMC Machete beadlock wheels add more scale realism and more grip on dirt, rocks, and all other off-road trails.

NOTE: Finished kit shown in photos is for illustrative purposes only. See needed to complete list below for a full list of items required to complete the model. 

Features:

The Axial SCX10 II UMG10 1/10 Scale Rock Crawler Kit was developed for builders that prefer to add their own details. The UMG10 starts with the proven SCX10 II kit as its foundation. The high performance SCX10 II kit platform is combined with the unique UMG10 cab forward body, bed cage and interior to give a realistic, yet aggressive, military inspired look. Plus, a host of included scale parts allow the freedom to add personal touches, and build the rig the way you want.

Axial also includes military-style MW19 1.9 beadlock wheels with MT45 1.9 tires in R35 compound, and a functional spare tire to finish off the look of this high performance, adventure ready kit. The off-road performance that has made the SCX10 II a class leader, carries on in this short wheelbase package. Add the radio and electronics you want, and build a custom, one of a kind machine that stands out on the trail.

CAB FORWARD BODY DESIGN 
The kit comes with a realistic, military based, cab forward body. The aggressive approach angle created by its front end design enables the UMG10™ to take on steep inclines. It's 11.4" (288mm) wheelbase helps with agility in challenging terrain.

REAR CAGE DESIGN 
The body and cage are bolted together. The hinge at the rear of the chassis allows you to tilt the body and cage up and out of the way. The spare tire carrier and hinged design that allows easy access to the battery and on-board components.

INTERIOR DETAILS 
Detail your UMG10 kit's interior with the parts provided. Choose from three hat styles for the driver's plastic molded head. Shift levers, a steering wheel, and a variety of decals are also included.

LED READY 
A total of eight mounting locations for LEDs are found throughout the vehicle. Four lights can be mounted in the front grille, two in the front bumper, and two in the rear frame plate. (LED lights are not included)

SCX10™ TRANSMISSION 
The SCX10™ transmission mimics a real transmission with a bell housing, oil pan and 4X4 transfer case. By placing the transfer case lower in the chassis and centering the driveshafts with the axle input housings, Axial created a more efficient driveline with improved driveshaft angles to reduce stress on moving parts. The transmission also includes a full set of ball bearings and all-metal internal gears. 

• Transfer case design helps keep the driveshafts centered and as low as possible in the chassis
• Final drive ratio range 33.69 – 54.15 with available spur and pinion gear combinations
• Comes with 56T spur gear and 15T pinion / 32-pitch for durability
• All-metal internal gears provide strength and durability
• Final drive ratio (FDR) 40.44 with a range from 33.69 - 54.15
• Scale looks mimic a full-size transmission and transfer case 
• 2-Speed Gear Set is available (not included - AXI31440)

AR44™ SINGLE PIECE HI-PINION AXLES 
The AR44™ axle features a high pinion gear set for a much lower gear ratio than most cars, plus a smaller pumpkin and added strength. The gear set helps to reduce the torque twist often associated with smaller gear sets. The axle itself retains the durability associated with the SCX10, despite being delivered in a smaller axle housing.

MW19™ 1.9 BEADLOCK WHEELS 
The UMG10 kit features MW19 1.9 beadlock wheels, with a spare that you can mount in the bed cage – five in total. It's a three piece wheel design, utilizing six screws which help the wheel firmly grip the MT45 tires. The wheel nut cap resembles a receptacle for a simulated central tire inflation system. The wheels are molded in black plastic and feature a standard 12mm wheel hex hub.

MT45™ 1.9 TIRES 
Keeping the truck on course and climbing difficult terrain are a set of MT45 tires molded in our sticky R35 compound rubber. The big block symmetrical tread pattern provides plenty of grip for climbing steep obstacles. 

• 4.6" x 1.4" / 1.9 (117mm x 35.6mm)
• R35 compound
