Traxxas TRX-4 Tactical Unit

This is the Traxxas TRX-4 Tactical Unit Camo Scale and Trail Crawler. 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! Just add a battery and charger to start traversing nearly any terrain!

TRX-4 Tactical Unit
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
      The TRX-4 Tactical Unit 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 leaves all the others behind. portal-axle-increased-ground-clearance

      Lightweight Night-Camo Body
      The Tactical Unit’s lightweight night-camo body lowers the overall center of gravity (CG) of the truck for greater speeds, tighter handling, and improved technical crawling. The steep approach angles and high center ground clearance provide an unstoppable combination to conquer any terrain. No matter where the adventure leads, the TRX-4 Tactical Unit is up to the challenge.

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

      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. 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 Tactical Unit adaptable to just about any situation or driving style. trx-4-high-low-two-speed-transmission

      Traxxas was the first to bring you fully waterproof RC vehicles years ago with our innovative designs. The TRX-4 Tactical Unit 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.

      3S Power System
      The 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!

      Aluminum GTS Shocks
      All 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.
