Its transmitter-controlled gearbox and Multi-Function Unit compatibility (sold separately) allow users to simulate gear shifts, lights, sounds, and even vibration—bringing the experience of long-haul trucking to life in 1/14 scale.

Key features of the Tamiya TAM56314 Knight Hauler

• 3-speed transmission – selectable gear ratios for realistic acceleration and torque control
• Dual rear axle drive – supports trailer towing and scale hauling performance
• Aluminum/polycarbonate ladder frame – combines strength and weight efficiency for structural integrity
• Leaf spring suspension – rigid setup for terrain stability and authentic movement
• Molded plastic cab – detailed shell with metal-plated trim for visual realism
• Chrome wheels and 88mm tires – enhance scale proportions and grip
• ESC-ready drivetrain – supports Multi-Function Unit integration for sound, light, and vibration effects

How does the 3-speed transmission enhance realism?

The Knight Hauler kit with 3-bevel differential gears, aluminum dummy dampers, and Type 540 motor features a transmitter-controlled gearbox that allows users to shift gears on the fly. With selectable ratios of 32.49:1 (low), 17.76:1 (medium), and 10.66:1 (high), the transmission replicates the torque and speed dynamics of full-size trucks. Whether accelerating from a standstill or cruising at scale highway speeds, the gear system adds depth and control to the driving experience. Reverse gear shifting is also supported, enabling realistic maneuvering and trailer alignment.

What makes the chassis suitable for heavy-duty hauling?

The Tamiya TAM56314 scale tractor truck with aluminum/polycarbonate ladder frame and leaf spring suspension is built for strength and stability. The hybrid frame construction offers rigidity without excessive weight, supporting the drivetrain and suspension components with precision. Leaf spring suspension ensures consistent wheel contact and terrain absorption, while aluminum dummy dampers add visual authenticity. With a 476mm wheelbase and 3.1kg assembled weight, the chassis is optimized for towing Tamiya’s range of 1/14 scale trailers with confidence and control.

How does the cab design reflect real-world trucking?

The 1/14 scale R/C truck with molded plastic cab, metal-plated trim, and transmitter-controlled gear shifting features a stylized cab inspired by American long-haul rigs. The molded plastic shell includes aerodynamic contours and chrome detailing, while the metal-plated trim adds a polished finish. With a height of 295mm and a length of 630mm, the Knight Hauler commands attention on the road or display shelf. The cab is designed to accommodate Multi-Function Units, allowing users to simulate engine sounds, horn, turn signals, and hazard lights—all controllable via a 4-channel transmitter.

What suspension and drivetrain features support terrain realism?

The Tamiya Knight Hauler with 0° caster/camber/toe angles, solid axle suspension, and ESC-ready drivetrain is engineered for scale accuracy and operational stability. The solid axle suspension maintains consistent wheel alignment, while the 0° caster, camber, and toe angles ensure neutral handling characteristics. Metal friction dampers simulate suspension movement, and the bevel gear differential supports smooth cornering. The ESC-ready drivetrain allows users to integrate advanced control systems, including multifunction units for enhanced realism.

How do the wheels and tires contribute to scale performance?

The Tamiya TAM56314 with 3.1kg weight, 476mm wheelbase, and 88mm diameter tires for scale realism includes chrome wheels fitted with 22mm wide treaded tires. These components provide grip and cushioning across varied terrain, while maintaining the proportions of full-size rigs. The wheel and tire setup complements the truck’s dual rear axle drive, ensuring traction and stability during towing operations. Combined with the rigid suspension and balanced chassis, the wheels and tires complete the Knight Hauler’s functional and visual package.

Is the Knight Hauler compatible with trailers and multifunction units?

The Tamiya TAM56314 big rig hauler with 630mm length, 186mm width, and 295mm height for trailer compatibility is designed to pair seamlessly with Tamiya’s 1/14 scale semi-trailers. When connected, the full rig can exceed one metre in length, creating a commanding presence for display or operation. The truck supports Multi-Function Units (sold separately), enabling users to control sound, light, vibration, and accessory functions such as auto support legs. This integration transforms the Knight Hauler into a fully interactive RC trucking experience.
