• Chassis-Mounted 2075X Metal Gear Digital Servo — This durable metal-geared servo provides responsive steering with sufficient torque to handle the larger wheels and heavier loads encountered in technical terrain, whilst the digital circuitry offers precise control and programmable settings.
• Extended Aluminium GTS Shocks — The extended shock absorbers complement the lifted suspension geometry and larger wheels, providing the additional travel necessary to properly support the weight distribution and suspension articulation requirements of a lifted crawler. Aluminium construction keeps weight reasonable whilst maintaining rigidity.
• TQi 2.4GHz Four-Channel Transmitter with Cruise Control — The included radio system offers reliable 2.4GHz frequency-hopping technology that eliminates interference issues, whilst the four-channel capability provides control for forward/reverse, steering, high/low range shifting, and cruise control features. Cruise control is particularly useful on technical terrain where maintaining constant throttle whilst negotiating obstacles becomes essential.
• Sealed Ball Bearings Throughout — All rotating components utilise sealed ball bearings rather than plain bushings, reducing friction and extending component lifespan whilst improving overall performance consistency.
• Hex Hardware with Rust-Resistant Black Oxide Coat — All fasteners are coated with black oxide plating that resists rust and corrosion, essential for an RC vehicle that will encounter wet and muddy terrain. This attention to detail in material selection extends the service life of your crawler.

Technical Performance

The Traxxas TRX-4 K5 Blazer High Trail Edition represents a masterclass in trail-specific engineering that prioritises obstacle-conquering capability over outright speed. The combination of the powerful Titan 21T reverse rotation brushed motor, trail-tuned XL-5 HV waterproof ESC, and two-speed transmission creates a powertrain specifically optimised for climbing steep grades and maintaining momentum through technical sections. The Titan motor's internal cooling fan ensures consistent performance throughout extended trail sessions, whilst the high-voltage capable ESC handles demanding driving conditions without thermal throttling. The factory-installed Long Arm Lift Kit working in concert with portal axles and extended aluminium GTS shocks provides over 9.9 centimetres of ground clearance—significantly more than standard models—allowing the K5 Blazer to traverse obstacles that would catch on conventional chassis designs. The steel ladder frame with 312mm wheelbase provides the rigid foundation necessary to support the lifted suspension whilst maintaining articulation through rough terrain. Large 2.2-inch chrome mag wheels wrapped in Canyon Trail tyres offer excellent grip and floatation characteristics across diverse surfaces including rocky terrain, sandy washes, and muddy trails. The XL-5 HV electronic speed controller is fully waterproof, essential for UK RC crawlers who explore wet conditions and creek crossings.
