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 fun adventure. In town, it powers over curbs, storms into puddles, and crawls through the deepest potholes. When the road ends, mud, rocks, and streams are easily conquered by this all-terrain machine. The Tactical Unit shares the same highly innovative features and capability of the TRX-4 Scale and Trail Crawler, but includes a rugged, lightweight tactical body for increased agility. 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 take on your wildest adventures.
Ultimate Ground Clearance
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
travelled and simply leaves all the others behind.
Torque Twist Eliminated
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.
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
Rigid Steel Frame
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.
Remote Locking Differentials
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. Our patented design has
been proven rugged and capable in the Traxxas Summit. New sleeved micro
cables control the differential action for scale appearance, without
limiting the huge suspension articulation.
45° Steering Angle
crawlers sacrifice turning radius for traction. The TRX-4’s remote
locking differentials disengage to take full advantage of its superior
45 degree steering angle. Once you clear the obstacle, re-engage the
differentials for ultimate traction.
Hi/Low Range Transmission
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.
Metal Gear Digital Servo
new full-metal gear digital servo gives you the durability and steering
authority you need to confidently and reliably power through tough
was the first to bring you fully waterproof RC vehicles years ago with
our 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
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
new XL-5 HV electronic speed control brings 3S LiPo capability for
stronger, more efficient running. New speed control profiles have been
added for smooth and precise control. A new Trail profile facilitates
smooth driving for most of your adventures, while a new 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
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.
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.
Aluminum GTS Shocks
new 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.
approach angles front and rear allow the TRX-4 Scale and Trail Crawler
to tackle big obstacles head on. The front motor design biases weight
forward for superior climbing ability compared to other designs.
