HOBAO HYPER EPX 1/10 CAB TRUCK ROLLER W/UNASSEMBLED CLEARBODY HB-GPX4E-CL

Overview

Hobao's first move into 1/10 scale on-road electric semi trucks has arrived with the Hyper EPX, and it represents a bold statement in the RC car UK market. This is Hobao's entry into a relatively untapped segment, offering something genuinely different for those who want to stand out from the crowd. The Hyper EPX is released as an 80% ARR (Almost Ready to Run) roller version, which means you get a fully assembled rolling chassis with a clear unassembled body shell, allowing you to equip the truck with your own choice of electronics. This approach is perfect for experienced RC enthusiasts who already have spare brushless motors, ESCs, and servos in their collection, or for those who want to tailor the truck's performance to their exact specifications.

Whether you prefer brushed or brushless power, 2S or 3S LiPo batteries, or even traditional NiMH cells, the Hyper EPX adapts to your setup. This flexibility means you can spec the EPX to whatever performance level you wish, from a gentle basher to a high-speed racer capable of handling the most powerful brushless combos available. The truck is engineered with high-end performance materials throughout, featuring CNC-machined aluminium components at every critical point. The rigid aluminium chassis, precision motor mount, floating servo mount, and front/rear gear differentials ensure that the EPX is built to handle serious power delivery and competitive racing demands.

If you are someone who likes to be different and not follow the herd, the new HoBao Hyper EPX semi truck is calling you. This is a ready-to-run RC truck for those with the knowledge and components to complete it, making it an excellent choice for intermediate and advanced RC drivers who value quality construction, versatility, and distinctive styling.

Key Features

• Full Ball Bearings — Every moving joint throughout the chassis uses sealed ball bearings rather than bushings, ensuring smooth operation, reduced friction, and extended component lifespan. This results in better performance, easier maintenance, and more reliable handling characteristics during high-speed runs.
• Ultra-Precise Aluminum Front/Rear Gear Diffs — The differentials are machined from aluminium with exceptional precision, allowing for smooth power distribution between the wheels whilst maintaining the handling balance during cornering. Gear diffs are more adjustable than standard diffs, letting you fine-tune how much slip each differential allows for your driving style and track conditions.
• Ultra-Stiff Front/Rear Suspension Arms — Rigid aluminium suspension arms provide a solid foundation for the wheel geometry and suspension tuning. The stiffness ensures predictable handling and reduces flex under hard acceleration and braking, critical for on-road performance at speed.
• Easy to Adjust Pivot Ball Suspension — Race-inspired pivot ball suspension geometry allows drivers to dial in precise handling characteristics by adjusting suspension angles. This feature is essential for competitive on-road driving, letting you optimise the truck's behaviour for different track surfaces and driving conditions.
• Aluminum Threaded Shocks — Unlike basic coil-over shocks, these aluminium units feature adjustable threaded bodies that allow you to fine-tune ride height and spring preload. This level of adjustability is crucial for dialling in the perfect setup for your specific driving style and track conditions.
• Front Foam Bumper — A protective foam bumper at the front absorbs impacts during high-speed running, protecting the servo and front chassis components from damage without adding significant weight or affecting aerodynamics.
• Front/Rear CVA Joints — Constant velocity angle joints ensure smooth power delivery and handling regardless of suspension movement, allowing the wheels to maintain optimal alignment throughout the suspension stroke for consistent grip and predictable handling.
• Battery Tray with Adjustable Magic Strip — The battery mounting system uses an adjustable magic strip fastener that allows you to quickly change batteries or adjust their position for weight distribution tuning, critical for fine-tuning the truck's handling balance.
• Aluminum Floating Servo Mount — The servo is mounted on an aluminium floating bracket that isolates vibration and shock loads, protecting your expensive servo from damage and ensuring precise, responsive steering throughout hard driving sessions.
• Front/Rear Belt Drive 4WD — The belt-driven 4WD system provides efficient, smooth power transfer to all four wheels whilst maintaining excellent weight distribution. Belt drive is quieter and more efficient than chain drive, and offers easier maintenance and adjustment compared to traditional gear-driven systems.
• CNC Aluminum Chassis — The main chassis is precision-machined from solid aluminium, providing maximum rigidity with minimal weight. CNC machining ensures perfect accuracy for all component fitment and adjustment features, giving you a platform built to the highest standards.
• 12mm Wheel Hex Drives — The wheels mount on robust 12mm hex adapters, a standard that provides excellent strength and durability whilst allowing easy wheel changes. Universal spec wheels mean compatibility across the HoBao Hyper range and many aftermarket options.
• CNC Aluminum Motor Mount — The motor is bolted to a precision-machined aluminium bracket that ensures perfect alignment with the driveline. This eliminates vibration and ensures maximum power transfer whilst protecting the motor from misalignment damage.
• Aluminum Brace Strut Bar — A reinforcing strut bar adds chassis rigidity without adding weight, improving handling precision and reducing chassis flex during hard cornering and acceleration.
• Quick Release Truck Body Shell — The clear polycarbonate body shell uses a quick-release mounting system, allowing you to remove the body in seconds for maintenance, repair, or customisation. The unassembled clear shell means you can paint or decal it to your own specification.
• Universal Spec 1/10 Tires and Wheels — The truck comes equipped with standard 1/10 scale on-road tyres and wheels that conform to universal specifications, meaning you have access to a huge range of aftermarket tyre options from specialist RC retailers.

Technical Performance

The HoBao Hyper EPX represents a significant engineering achievement in the 1/10 scale on-road RC market. Built around a precision CNC-machined aluminium chassis, every critical component is engineered for strength and adjustability. The truck measures 359mm in length without the body shell and 403mm with it installed, giving it authentic semi-truck proportions at 1/10 scale. The width of 200mm and height of 93mm without the body ensure a low centre of gravity ideal for high-speed on-road running, whilst the overall weight of just 1.53kg means you get exceptional power-to-weight ratio regardless of which motor and ESC combination you choose. The wheelbase of 262mm, combined with front and rear tracks of 200mm and 205mm respectively, creates a balanced platform that delivers predictable handling characteristics. The EPX accepts 7.4V LiPo or 7.2V NiMH batteries, meaning you can run affordable brushed motor setups for casual bashing or modern brushless systems for competitive racing. The belt-driven 4WD system with front and rear differentials distributes power intelligently to all four wheels, whilst the pivot ball suspension with adjustable threaded shocks provides the fine-tuning capability needed for serious on-road competition. Full ball bearings throughout the drivetrain and suspension ensure smooth, responsive performance lap after lap. This is a truck built to the highest standards of precision and quality, ready to accept whatever brushless power plant you can throw at it.
