As a seasoned RC vehicle reviewer, I’ve had my fair share of test drives. But when it comes to big rig replicas, nothing beats the spectacle of Tamiya’s RC King Hauler and RC Grand Hauler. Both these models are a marvel in miniature engineering and provide an unmatched RC experience. Let’s get into gear and delve into the detailed features of these two remarkable machines.
Tamiya Grand Hauler: A True Road Beast
Upon unboxing the Tamiya Grand Hauler, the first thing that struck me was its sheer size. This behemoth is a faithful reproduction of a North American custom truck, featuring a sturdy ladder frame chassis, aluminum side channels, and resin cross members.
The suspension system uses metal leaf springs and friction dampers, which combine to deliver remarkably smooth performance. With a front-mounted motor powering the rear axles, the Grand Hauler mimics the powertrain of its real-life counterpart.
But the true realism of the Grand Hauler is unlocked when paired with Tamiya’s Multi-Function Control Unit (MFC). From digitally recorded engine sounds to a litany of other operational noises, this MFC offers an unmatched audio-visual experience that will have you feeling like you’re behind the wheel of a true big rig.
Tamiya King Hauler: Luxury on a Miniature Scale
Moving on to the RC King Hauler, it immediately stands out with its pre-painted metallic black finish and chrome-plated accents, such as the front grille and air cleaners. The precision-molded tractor-truck body is nothing short of a visual treat.
Just like the Grand Hauler, the King Hauler’s chassis is paired with front and rear metal leaf spring dampers, providing excellent durability. The power is delivered from a front-mounted motor to the rear wheels, replicating the drive system of real-world trucks. This rig also offers a 3-speed transmission with manually controllable gear changes, adding to the overall realism.
The MFC unit elevates the King Hauler experience to another level. It amplifies the truck’s operational sounds, including air horns, gear shifting, and more. Coupled with the interactive lighting, the King Hauler offers an immersive RC experience.
Both the Tamiya Grand Hauler and RC King Hauler have the ability to couple with one of six available semi-trailers. This feature allows for an astounding one-meter-long combination, providing a truly spectacular sight as it powers down the track.
Closing Thoughts from the Cab
After a thorough road test, I must say that both the Tamiya Grand Hauler and RC King Hauler are remarkable machines. Both offer unique features, outstanding performance, and an impressive level of detail. Whichever model you choose, ensure you pair it with the MFC unit for the full range of lights and sounds – it’s an investment you won’t regret.
Until the next road test, keep those motors running!
