Key Features
- Precision Servo Mount — The floating servo mount design, as featured on the complete HoBao Hyper EPX 1/10 semi truck, isolates vibration and ensures your steering servo operates with maximum precision and responsiveness, which is essential for maintaining tight handling characteristics during high-speed on-road driving.
- Integrated Belt Adjustment System — This component includes the belt adjustment mechanism that allows you to maintain optimal tension on your front and rear belt drive 4WD system, ensuring smooth power delivery and preventing belt slip or premature wear that could compromise acceleration and handling.
- OEM HoBao Quality — As a genuine manufacturer part, this servo mount and adjustment mount meets HoBao's strict engineering standards and tolerances, guaranteeing perfect fitment and reliability with your EPX platform chassis.
- Universal EPX Compatibility — This part works across the entire EPX 1/10 semi truck range, whether your vehicle features a clear acrylic body, pearl white paintwork, or vibrant yellow finish, making it an essential backup spare for any EPX owner.
- Durability Under Load — The component is engineered to withstand the demands of competitive on-road racing and recreational bashing, maintaining its integrity through thousands of steering inputs and belt drive cycles.
- Critical Maintenance Component — Keeping a replacement servo mount and belt adjustment assembly in your spares box ensures you can quickly restore your vehicle to full performance if damage occurs, minimising downtime between driving sessions.
Technical Performance
The HoBao Hyper EPX 1/10 semi truck platform represents a significant achievement in precision on-road RC engineering, and this servo mount and belt adjustment component plays a vital role in that performance equation. The complete EPX vehicle features a CNC aluminium chassis with a 262mm wheelbase (10.31 inches), 200mm front track (7.87 inches), and 205mm rear track (8.07 inches), creating a stable platform that benefits from precise servo control and optimised belt tension. The vehicle measures 359mm in length without its body (403mm with the realistic semi truck shell fitted) and weighs 1.53kg (3.37 lbs), a balanced specification that demands accurate steering input from a properly functioning servo mount. The EPX features a sophisticated front and rear belt drive 4WD system with CNC aluminium motor mount and quick-release truck body shell, all of which depend on the servo mount and belt adjustment assembly to function correctly. Your servo needs responsive, vibration-isolated mounting for the vehicle's precise steering to translate perfectly, whilst the belt adjustment mechanism must maintain consistent tension across thousands of driving cycles. This genuine HoBao component, as used in factory EPX builds, ensures both of these critical functions operate flawlessly, whether you're running a 7.4V LiPo or 7.2V Ni-MH battery system.

Frequently Asked Questions
- Which HoBao EPX models is this servo mount compatible with? — This H22304 servo mount and belt adjustment assembly is compatible with all HoBao Hyper EPX 1/10 semi truck variants, specifically the HB-GPX4E-W (pearl white body), HB-GPX4E-CL (clear body), and HB-GPX4E-Y (yellow body) models. If you own any of these ready-to-run RC cars UK, this is the correct replacement part.
- Why would I need a replacement servo mount for my HoBao EPX? — The servo mount is critical for steering control and can become damaged through impacts, accidents, or normal wear over extended use. If your steering feels sloppy, unresponsive, or your vehicle pulls to one side unexpectedly, the servo mount may need replacement. Similarly, if you're having difficulty adjusting belt tension, a worn mount assembly could be the culprit.
- How often should I check my servo mount and belt tension? — For regular weekend bashers, inspect your servo mount before each driving session and check belt tension monthly. Competitive drivers should check these components even more frequently, as they directly affect handling precision and drivetrain efficiency. A well-maintained servo mount and properly tensioned belt can significantly extend the lifespan of your servo and belt drive components.
- Is this part essential for beginners? — This is a replacement spare part rather than a component for initial assembly, so beginners won't need it immediately. However, keeping one in your spares box is sensible insurance against accident damage, particularly if you're learning on your new brushless RC ready to run vehicle.
- What tools do I need to install this servo mount? — Installation typically requires basic RC tools including hex keys and potentially small screwdrivers, depending on how comprehensively you're replacing the mount assembly. Consult your HoBao EPX manual for detailed installation instructions specific to your vehicle variant.
- Can I use this part on other HoBao vehicles? — This servo mount and belt adjustment assembly is specifically engineered for the EPX 1/10 semi truck platform and is not compatible with other HoBao model ranges such as the GPX4, H4, EX10, or other Hyper series vehicles.
