Traxxas TRX4 Tactical 1/10 Trail Rock Crawler Tactical Unit
The Traxxas TRX-4 Tactical Unit is a rapid-response vehicle designed to charge into practically any situation, emerging unscathed and ready for the next adventure. Its lightweight body offers high-speed agility and superior technical crawling. Where other trucks fear to go, the Tactical Unit charges ahead full throttle!
The secret to the Tactical Unit’s extreme all-terrain capability lies underneath its tough camouflaged body. Exclusive portal axles deliver maximum ground clearance and virtually eliminate torque twist. Remotely-actuated front and rear differentials unlock for all-out speed and lock for rock-gripping traction on treacherous surfaces. The high/low range transmission transforms the Titan motor’s power into incredible torque in low gear or blazing speed in high gear. Built the Traxxas way, the Tactical Unit is tough, powerful, and ready to tack on your wildest adventures.
Heavy Duty Steel Frame Rails
A thick 1.5 mm steel ladder frame with molded cross members provides exceptional torsional rigidity to resist even the worst chassis twisting articulation. This extremely rigid backbone 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.
The innovative shock towers allow four separate “bolt-on” wheelbase positions: 300, 312, 324, and 336 mm to accommodate custom body fitment. Further fine tuning is possible with the axle links and adjustable shock position.
The finer details matter so we incorporated wire retainers into the frame rails, which provide a clean look and keep the wiring more secure from off-road hazards.
Dual-Fit Battery Tray
Tactical Unit’s dual-fit battery tray offers extreme flexibility when choosing batteries. For extended run times, the large upper tray accommodates a full-length 5000 mAh 3-cell Lipo or 7600 mAh 2-cell Lipo. A hinged battery strap provides quick and secure battery mounting without pins to lose in the field. The innovative strap flips over to adjust for different height batteries. A smaller integrated tray accepts smaller Traxxas batteries (that fit our 1/16 scale models) for increased forward weight bias.
Though floor pans integrate with the wheel wells to enhance the scale appearance and keep debris out of the chassis.
Aluminum Scale Shocks
All new oil-filler coil-over GTS shocks were created exclusively for the TRX-4 chassis to smooth out even the roughest trails. These silver- anodized aluminum shocks deliver silky-smooth damping and feature threaded bodies for easy ride height adjustment. The convincing scale realism looks great and they perform even better with an O-ring cap seal and dual X-ring shaft seals.
Heavy Duty Steel Links
Thick 5mm diameter steel links feature tough, fully-captured heavy-duty rod ends with steel hollow balls for exceptional strength and durability. This is one rig that won’t strand you on the trail with a broken suspension link.
Exclusive to the TRX-4 chassis, portal axles lift the differential pumpkin to provide incredible ground clearance. This radical design also improves axle geometry and reduces strain on the driveshafts. Steel gears ensure trouble-free performance, no matter how technical the climb.
Torque Twist Eliminated
On conventional rigs with the limited gear reduction in the differentials, motor torque is applied to the frame to the point of twisting you right off the rocks. The TRX-4 chassis’ radical portal axle design reduces the gear ratio at the wheels, virtually eliminating torque twist through the chassis. Total axle gear reduction is over twice non-portal designs so Titan motor torque delivers smooth forward motion, not frame twist.
T-Lock Remote Locking Differentials
Conventional crawlers equipped with axle spools sacrifice turning radius for traction. Traxxas gives you the freedom and versatility to lock and unlock both the front and rear differentials to suit your driving needs, all controlled remotely 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 differentials, for superior pull andgrip over extreme terrain. Our patented design has been proven rugged and capable in the Traxxas Summit.
High/ Low Transmission
In high gear, the Tactical Unit charges ahead full-throttle at speeds more commonly associated with bashing trucks. When you reach an obstacle, flip the switch on your transmitter to engage low range and conquer tough terrain with fine throttle control and exceptional torque.
Hardened Steel U-Joints
Hardened steel U-joints on the front and rear driveshafts provide smooth, reliable power delivery for non-stop fun.
Sealed Ball Bearings
Black sealed ball bearings resist mud and dirt to keep your rig tolling smoothly.
Raised Center Driveshafts and Suspension Links
TRX-4’s radical portal axle design raises the driveshafts higher to improve axle geometry and reduce driveshaft angles. Higher driveshafts and suspension links pass over abstacles to avoid high-centering your truck and reduce overall grinding wear.
High Steering and Drag Links
The steering link and drag link attach high on the portal axles, raising them away from possible damage. This allows the Tactical Unit to attack obstacles head on, reducing the risk of hitting the steering linkage on rocks.
45-Degree Steering Angle
With the front differential unlocked, the superior 45-degree steering angle negotiates around even the tightest bends with ease. This helps avoid awkward reversing maneuvers in tight spaces.
Extreme Approach Angles
With a 53.17 degree out-of-box approach angle in the front, Tactical Unit is ready to climb walls. An equally impressive 41.67 degree rear approach angle provides extreme capability, even in the deepest ruts.
High Ground Clearance
Portal axles help raise the center ground clearance to an unparalleled 3.14 inches (80mm), while raised suspension links and driveshafts clear the rocks underneath. Superior capability equals more fun no matter where your adventure takes you.
Front Motor Design
The Tactical Unit’s large 550 size brushed 21-turn Titan motor provides smooth reliable power and loads of torque to climb the toughest obstacles. The front mounted orientation moves the weight bias forward to get you up and over obstacles with improves traction.
New XL-5 HV ESC
HV stands for compatibility with the high-voltage 3S LiPo battery packs for greater efficiency and power. In addition to the three standard profiles (Sport, Race, Training Mode), the XL-5 HV features a Trail profile that serves up a little bit of drag brake for smooth intuitive driving for most of your adventures. A new Crawl profile introduces hilll hold and instant reverse for extremely technical courses. Either will help you navigate the trail with ease.
Titan 21-turn 550 Motor
The Tactical Unit’s massive Titan 21-turn motor pumps out huge torque to get you up and over anything that gets in the way. An integrated cooling fan keeps temperatures down for extended run times.
Waterproof Metal Gear Servo
A new full-metal gear digital servo gives you the durability and steering authority you need to confidently and reliably power through tough challenges.
TQi 4-Channel Radio System
The Traxxas TQi radio system features exclusive 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 match your pace. The grip-mounted rocker switch selects high or low range gears to suit the terrain while a separate toggle switch engages or disengages the locking differentials, all on the fly. Best of all, the TQi is compatible with the Wireless Module so you can set up everything right from your smartphone.
Waterproof Micro Servos with Sleeved Cables
The Traxxas Tactical Unit uses three fully-waterproof micro servos to actuate the front and rear differentials as well as the high/low range selection on the transmission. Sleeved micro cables eliminate complicated linkages that would otherwise limit suspension articulation.
Molded Inner Fenders
Tough inner fenders integrate with the floor pans and shock towers to provide substantial look and feel to the Tactical Unit. The authentic realism adds to the fun while also helpig to keep rocks, mud, and twigs out of the chassis.
Functional rock sliders help prevent damage and provide extra support for the body. The additional bracing adjusts for different widths.
1.9″ Scale Wheels and Tires
The 1.9″ wheels provide a bold scale look for the Tactical Unit and come pre-glued and mounted to aggressive, S1 compound Canyon Trail tires. Deep tread blocks flex for maximum traction on the rocks. The trail-tuned foam inserts provide realistic sidewall flex for authentic climbing action. A standard 12mm steel hex makes the Tactical Unit chassis compatible with popular 1.9″ wheel and tire combinations.
Tough Fender Flares
Though, yet flexible and impact resistant fender flares fasten tightly to the inner fender wills to provide rugged protection and awesome looks.
Secure Body Mounting System
The Tactical Unit body secures to the frame at the rear bumpers, rock sliders, and with the top mounting posts. This multi-point mounting system prevents unrealistic body shake and provides rigid support for the spare tire and accessories in the rear.
