Overview
The HoBao HYPER EXTREME VTE2 1/7 Centre Spool Set with 34T Spur (Model H85138) is an essential upgrade component for serious RC car enthusiasts in the UK who demand precision engineering and competitive performance. This centre spool set is specifically designed for the HoBao VTE2 platform, one of the most respected 1/7 scale on-road electric RC cars available today. Whether you're looking to fine-tune your existing setup, replace worn components, or optimise your drivetrain for maximum efficiency, this genuine HoBao spare part delivers the quality and reliability that competitive racers expect from a trusted manufacturer.
HoBao has built its reputation on manufacturing high-quality RC components that meet the exacting standards of serious hobbyists and competitive drivers alike. The VTE2 platform represents years of engineering refinement, and this centre spool set is a critical component in the transmission system that directly influences your RC car's acceleration, handling characteristics, and overall performance on the track. By choosing genuine HoBao spares, you're investing in components that have been tested and validated by the manufacturer to work seamlessly with your vehicle, ensuring consistent performance and reliability whether you're practising at your local club track or competing in regional championships across the UK.
This centre spool set features a 34-tooth spur gear, which is a critical drivetrain component that affects your vehicle's gearing ratio and top speed capability. The spur gear meshes with the pinion gear on your motor to transfer power from the motor to the wheels, making it one of the most frequently upgraded components for racers who want to fine-tune their setup for specific track conditions or racing disciplines within the RC car UK hobby community.
Key Features
- 34-Tooth Spur Gear — The spur gear is the heart of your transmission system, determining your gearing ratio and directly impacting acceleration and top speed; a 34T spur is a popular choice for balanced performance on on-road tracks, offering a good compromise between punch off the line and top-end speed capability.
- Centre Spool Design — The centre spool mounting system ensures precise gear engagement and minimal backlash, which is essential for consistent power delivery and responsive handling during high-speed cornering and aggressive manoeuvres on on-road circuits.
- Genuine HoBao Component — As an official HoBao spare part, this centre spool set is manufactured to the exact specifications required by the VTE2 platform, guaranteeing perfect fitment and compatibility without any modifications or adjustments needed.
- Optimised for On-Road Performance — This component is specifically engineered for the demands of on-road electric RC racing, where precise gear meshing and reliable power transmission are critical to competitive lap times and race-day reliability.
- Direct Replacement Part — Whether you're replacing a worn or damaged spur gear or experimenting with different gearing options to optimise your setup, this centre spool set provides everything needed for a straightforward installation without additional tools or modifications.
- Competition-Grade Engineering — HoBao's manufacturing standards ensure tight tolerances and superior materials, translating to smoother power delivery, reduced drivetrain noise, and improved longevity compared to inferior aftermarket alternatives.
Technical Performance
The centre spool set with 34-tooth spur represents precision engineering at its finest. The spur gear works in conjunction with your motor's pinion gear to establish the gearing ratio that determines your vehicle's acceleration characteristics and maximum velocity. A 34-tooth spur is a versatile choice that provides balanced performance across most on-road track layouts, offering sufficient low-end torque for responsive acceleration while maintaining a respectable top speed for competitive racing. The centre spool design minimises radial run-out and ensures consistent gear mesh with the pinion, which is crucial for smooth power delivery and reduced vibration during high-speed runs. HoBao's engineering excellence means this component is manufactured from high-quality materials with tight tolerances, ensuring durability and reliability even under the demanding conditions of regular competitive racing. The precise engineering of the spur gear teeth and the centre spool mounting system work together to eliminate backlash, which is the slight movement between gears that can result in sluggish throttle response and unpredictable handling. For drivers who understand the importance of drivetrain performance in their overall setup tuning, the quality and precision of this HoBao component will be immediately apparent in improved throttle response, smoother acceleration, and more predictable handling characteristics during high-speed cornering on on-road racing circuits throughout the UK.

Frequently Asked Questions
- What is a centre spool set and why do I need it? — The centre spool set is the mounting assembly for your spur gear, which is a critical drivetrain component that meshes with the pinion gear to transfer power from your motor to your wheels. A centre spool set determines your vehicle's gearing ratio, which directly affects acceleration and top speed. Many racers upgrade or replace their spur gears to fine-tune their setup for specific track conditions or racing preferences, making this a commonly purchased spare part for active RC racers across the UK.
- How does the 34-tooth spur gear compare to other gear ratios? — The tooth count on a spur gear directly influences your gearing ratio; a 34-tooth spur is considered a mid-range option that provides balanced performance for general on-road racing. Lower tooth counts (like 32T or 33T) provide quicker acceleration but lower top speed, whilst higher tooth counts (like 35T or 36T) offer higher top speed but less aggressive acceleration. The 34T is a popular starting point for many drivers, offering versatility across different track layouts and racing styles.
- Is this centre spool set compatible with my HoBao VTE2? — Yes, this H85138 centre spool set is specifically designed for HoBao VTE2 models, including the VTE2-8 (1/8 scale) and VTE2-V2 (1/7 scale) versions. Check your model designation to confirm compatibility, but if you own a VTE2 platform vehicle, this genuine HoBao component will fit perfectly without any modifications required.
- How often should I replace my spur gear? — The lifespan of a spur gear depends on how frequently you race, your driving style, and the quality of maintenance you perform. High-competition racers may replace spur gears regularly as part of their maintenance routine to ensure optimal performance, whilst casual drivers may only need replacement when visible wear or damage occurs. Regular inspection of your spur gear for chipped teeth or signs of wear is recommended, especially if you notice changes in throttle response or acceleration characteristics.
- Can I use different tooth counts with this centre spool? — Yes, the centre spool assembly is designed to accept different spur gear tooth counts, allowing you to experiment with various gearing options to optimise your setup. However, you must purchase the appropriate spur gear separately; this product includes the 34-tooth spur. Always ensure any replacement spur gears are compatible with the VTE2 platform and properly meshed with your pinion gear.
- What tools do I need to install this centre spool set? — Installation of this centre spool set typically requires basic RC tools including an adjustable wrench or spanner set and possibly a screwdriver, depending on your vehicle's specific mounting system. Most HoBao components are designed for straightforward installation by anyone with basic RC maintenance experience, though consulting your VTE2 manual is always recommended for specific instructions and torque specifications.
