Traxxas Stability Management

Micro Receiver, TQi 2.4GHz with Traxxas Link and TSM (5-channel) (#6533) (three-quarter view)Traxxas Stability Management (TSM) makes it possible to experience all the extreme power, speed, and acceleration that was engineered into Traxxas models by making it much easier to control the vehicle on common slippery surfaces such as loose dirt, smooth concrete, and even ice and snow. Punch it off the line and TSM goes to work sensing the vehicle’s direction and making steering corrections to provide straight-ahead full throttle acceleration without fishtailing, spinouts, and loss of control. TSM also works during cornering, first making intuitive corrections to maintain the vehicle’s line, then hammer the throttle earlier in the turn for much faster exit speeds. Braking is dramatically improved as TSM works to keep Traxxas trucks arrow straight until they come to a complete stop. Traxxas TSM gives all the benefits modern electronic stabilization has to offer without intruding on driving fun or introducing unexpected side effects that can be found on other systems such as drastically reduced turning radius, braking assistance that times out (quits), throttle restrictions, and an overall disconnected driving feel. Traxxas engineers developed superior tuning algorithms that run on high-speed, precision electronic components to create a system that works invisibly, in the background, without ever limiting throttle. TSM can be fine tuned (or turned off) for different surfaces by simply adjusting the multi-function knob on the TQi transmitter, or by adjusting the slider in the Traxxas Link app. The result is driving faster, with more ease, and having more fun. In fact, the driver may not even realize how much TSM is helping until it is turned off and their driving skills are tested without it!

5-channel Micro Receiver with Fail-Safe Security

The TQi 2.4GHz micro receiver uses an integrated LINK button for fast and easy binding to the receiver, and the two-color LED indicates power-on and bind status for fool-proof control and convenience. Traxxas Link Model Memory allows the receiver to recognize up to thirty TQi 2.4GHz Traxxas Link enabled transmitters—just switch on and drive. In the event of signal loss due to an accidental switch-off or depleted batteries, the receiver will automatically return the throttle to neutral and hold the last commanded steering position. The Fail Safe programming is built-in and does not need to be set or activated. Three telemetry ports are incorporated in the 5-channel receiver to allow real-time data to be transmitted from your Traxxas model to the TQi transmitter.

Modular Simplicity

Slash 4X4 Ultimate (#68077-4) Chassis Modular Design

Old designs made servicing of 4-wheel drive vehicles cumbersome and time-consuming. Traxxas has a better way. The Slash 4X4 Ultimate's modular design allows the entire front section to be removed with just five screws, and the rear assembly with just four screws. In less than a minute using a power screwdriver, you have full access for easy service and adjustment.

The Slash 4X4 Ultimate needs a fast and powerful servo to match its lightning-quick reflexes. New to the Slash Ultimate is the fully waterproof #2075R digital metal gear servo. This servo combines commanding steering authority with the superior durability of all-metal gears for the ultimate driving experience.

Ultra Efficient Shaft-Driven 4WD

The Slash 4X4 Ultimate uses just three gear meshes to drive all four wheels, eliminating the need for a multi-gear transmission. The highly efficient drivetrain spins effortlessly on rubber-sealed ball bearings, and is integrated seamlessly into the Slash 4X4 Ultimate's unique low-CG chassis for optimum performance and easy maintenance. The center driveshaft is formed from extruded aluminum and extremely lightweight, contributing to the Slash 4X4 Ultimate's right-now acceleration. There are no dogbones to wear, no drive cups to wobble and the shaft runs perfectly straight and true with superior rigidity and durability.

Low-CG Chassis

Slash 4X4 Ultimate's performance refinements begin with a dark charcoal gray low-CG (low center of gravity) chassis. The battery and electronics are held as deep in the chassis as possible to position weight low in the chassis. Arrow-straight, hard-charging acceleration with Slash 4X4 Ultimate (#68077-4) Chassis Top ViewExtreme Brushless Power and 4WD requires a chassis that won't flex under load. To offer the necessary rigidity, the chassis is reinforced by integrated ribs that form a triangulated structure optimized for the loads imparted by the suspension and powertrain. Underneath, the chassis is ultra-smooth to reduce drag and prevent snags whether you're blasting through whoops on the track or blazing trails in your backyard. The low-CG design dramatically increases corner speed and stability no matter where you drive. On the race course, Slash 4X4 Ultimate's low center of gravity allows high-output Velineon brushless power to be channeled into the track with superior traction, resulting in harder launches and faster lap times.

High-Capacity GTR Shocks Slash 4X4 Ultimate (#68077-4) Blue-Anodized GTR Shocks

Traxxas GTR shocks represent the peak of suspension technology. The blue PTFE-coated aluminum shock bodies have 13mm bores to hold over 70% more oil than the standard Slash Ultra Shocks and their slick titanium-nitride coated shafts resist scuffing, increase durability, and eliminate "stiction." The shocks are sealed by X-rings to keep oil in and dirt out for smooth, consistent damping, and plush suspension action, lap after lap. Between runs, spring preload and ride height changes are as simple as turning the threaded spring collars--no clips or spacers required.
