Overview
The HOBAO EPX Transmission Gear with CNC Aluminium Gear Mount (H22310) is a premium upgrade component designed for serious RC enthusiasts and competitive drag racing pilots in the UK. This precision-engineered transmission assembly represents the pinnacle of HoBao's manufacturing expertise, combining cutting-edge CNC machining with hardened steel components to deliver exceptional durability and performance. Whether you're building a high-performance 1/10 scale drag car or upgrading an existing RC car UK setup, this transmission gear system provides the mechanical foundation needed to handle extreme acceleration and sustained high-speed operation.
HoBao has established itself as a leading manufacturer of competition-grade RC vehicles and components, and this transmission assembly exemplifies their commitment to quality and performance. The EPX transmission gear with its CNC aluminium mount is engineered to satisfy the demands of both amateur enthusiasts and professional RC racers who refuse to compromise on reliability. This component is particularly valued in the drag racing community, where consistent power delivery and mechanical durability are absolutely critical to success on the strip.
This transmission system is not a ready to run RC car, but rather a specialised drivetrain component for builders and upgraders. It represents an investment in performance that will reward you with smoother gear engagement, improved power transmission efficiency, and the peace of mind that comes from using factory-approved HoBao engineering in your build.
Key Features
- All Metal Gear Transmission Design — The complete transmission assembly features hardened steel gears throughout, eliminating plastic components that can strip or fail under load. This all-metal construction ensures maximum strength and longevity, particularly important for drag racing applications where instantaneous power delivery is essential.
- CNC Aluminium Gear Mount — Precision computer numerical control machining produces a gear mount of exceptional accuracy and durability. The aluminium construction keeps weight to a minimum whilst the CNC tolerances ensure perfect gear alignment and meshing, reducing friction and maximising power transfer efficiency.
- High-Strength Steel Transmission Shafts — Heavy-duty hardened steel shafts resist bending and twisting under extreme torque loads, providing the rigid support needed for consistent performance during high-acceleration drag runs and sustained high-speed operation.
- Three-Gear Transmission Design — The sophisticated three-gear system includes a 27T idler gear, 51T differential housing gear, and 21T layshaft gear, providing optimised gear ratios for smooth power delivery and efficient energy transfer through the drivetrain.
- Hardened Steel Differential Gears — The heavy-duty metal sealed gear differential features 500K silicon oil lubrication, providing superior protection and performance. The sealed design keeps contamination out whilst the high-viscosity oil maintains optimal differential function under extreme driving conditions.
- Precision Engineering for Competition Use — Every component is designed and manufactured to exacting specifications that meet the demands of competitive drag racing. The tolerances and materials ensure consistent performance run after run, essential when competition margins are measured in thousandths of a second.
Technical Performance
The HOBAO EPX transmission gear assembly represents a significant investment in drivetrain quality and performance. The all-metal construction with hardened steel gears and shafts provides the mechanical strength necessary for drag racing applications where acceleration forces can exceed 2G. The three-gear design with specific ratios of 27T, 51T, and 21T creates an optimised power delivery curve that balances acceleration response with efficiency. The CNC aluminium mount ensures that gear alignment remains perfect throughout the drivetrain's operational life, preventing the gradual wear and misalignment that can occur with lower-quality components. The sealed differential with 500K silicon oil provides superior lubrication and protection, maintaining performance consistency even under the extreme thermal conditions generated during high-speed runs. This transmission system is engineered to work as part of a complete mid-motor 1/10 scale drag car setup, where it integrates with HoBao's carbon fibre chassis and suspension systems. The build quality and material selection throughout this component reflect professional-grade engineering standards, making it a favourite choice for serious competitors and dedicated enthusiasts building or upgrading their RC cars UK.

Frequently Asked Questions
- What scale RC car is this transmission gear suitable for? — This transmission gear assembly is specifically designed for 1/10 scale RC vehicles, particularly HoBao's EPX drag racing platform and other compatible mid-motor drag cars. The dimensions and gear ratios are optimised for this scale class.
- Is this suitable for beginners? — This is a specialist component best suited to experienced RC builders and drag racing enthusiasts rather than beginners. Installation requires knowledge of transmission assembly, proper lubrication, and understanding of gear ratios. We recommend purchasing as part of a complete kit or with professional installation support.
- What makes the CNC aluminium mount better than standard plastic or cast mounts? — CNC machined aluminium provides superior precision, weight savings, and durability compared to plastic or standard cast components. The tight tolerances from CNC machining ensure perfect gear alignment, which reduces friction losses and improves efficiency. Aluminium also provides better heat dissipation and won't strip or crack under extreme loads.
- Can this transmission be used as an upgrade for other RC cars? — This transmission assembly is specifically engineered for HoBao EPX and compatible mid-motor 1/10 scale drag cars. Compatibility with other brands or scales is not recommended without expert verification of mounting dimensions and ratios.
- How often will I need to maintain this transmission? — The sealed differential with 500K silicon oil requires regular inspection and periodic oil changes depending on usage intensity. After competitive drag racing events, check for debris and ensure proper lubrication levels. With proper maintenance, this all-metal transmission system will provide reliable service for many seasons.
- What is the difference between this and lower-cost transmission systems? — The HOBAO EPX transmission distinguishes itself through all-metal gear construction rather than plastic components, CNC precision machining for perfect alignment, hardened steel shafts that resist deformation, and a sealed differential with high-viscosity oil. These features combine to deliver superior durability, efficiency, and consistent performance across many competitive runs.
