HOP-0151

Overview

The HoBao Motor Mount Slider for 50mm Motor (HOP-0151) is a precision-engineered hop-up component designed for RC enthusiasts looking to optimise their 1/7 and 1/8 scale electric on-road racing machines. This adjustable motor mount slider represents the kind of detailed upgrade that separates competitive RC car UK builders from casual bashers. Whether you're fine-tuning a HoBao Extreme VTE2 or seeking to extract maximum performance from your electric RC car, this component offers the adjustability needed to dial in perfect motor mesh and power delivery characteristics.

HoBao has established itself as a manufacturer of high-performance RC vehicles and upgrade components, particularly within the 1/7 and 1/8 on-road electric racing categories. The Motor Mount Slider is a testament to HoBao's commitment to providing competitive racers with the tools they need to achieve consistent, repeatable results. This is not a beginner's part, but rather a serious upgrade for those who understand that motor positioning directly affects acceleration, top speed stability, and overall drivetrain efficiency in electric RC racing applications.

If you're running a brushless motor setup on your RC car and seeking to achieve professional-grade performance tuning, the Motor Mount Slider allows for micro-adjustments to motor mounting position without requiring a complete redesign of your drivetrain. This flexibility is invaluable for anyone competing in UK RC racing series or simply pursuing the best possible setup from their ready to run RC investment.

Key Features

• 50mm Motor Compatibility — This slider is specifically designed to accommodate 50mm diameter brushless motors, which are standard equipment in competitive 1/7 and 1/8 scale electric on-road RC cars. The 50mm size represents the sweet spot for power delivery and weight distribution in this vehicle class.
• Adjustable Mounting Position — The slider mechanism allows you to move the motor mount forward or backward along a set travel path, enabling precise adjustment of motor mesh with the transmission gears. Correct motor positioning is critical for reducing drivetrain noise, minimising wear, and maximising power transfer efficiency.
• Precision Engineering — Manufactured by HoBao using quality materials and tight tolerances, this component integrates seamlessly with HoBao's modular chassis design philosophy, ensuring consistent performance and repeatability between adjustments.
• Direct OEM Compatibility — Specifically designed for HoBao 1/7 Extreme VTE2-V2 On-Road Electric ARR and HoBao Extreme VTE2 1/8 On Road EP models, ensuring perfect fitment and functionality without modification or adaptation.
• Competition-Grade Component — This is the exact specification upgrade that serious racers and tuners use when preparing their RC cars for competitive events, track days, and performance testing throughout the UK and beyond.

Technical Performance

The Motor Mount Slider represents the kind of detail-focused engineering that defines HoBao's approach to on-road electric RC design. In competitive 1/7 and 1/8 scale racing, motor mesh adjustment is fundamental to achieving optimal drivetrain engagement. Too loose, and you lose efficiency and experience noise and slippage under acceleration. Too tight, and you risk damaging precision components and creating unnecessary drag that reduces top speed. This slider mechanism allows drivers and mechanics to find that perfect middle ground through simple, repeatable adjustment procedures. The 50mm motor size sits at the intersection of power output and weight efficiency, allowing vehicles to achieve the high speeds and rapid acceleration expected from brushless electric RC cars whilst maintaining the structural integrity required for sustained competitive use. The slider's design integrates with HoBao's mid-motor transmission architecture, which has proven itself in countless races and competitive environments. Material selection and manufacturing precision ensure that the adjustment mechanism remains stable during operation, with no creep or slippage that might cause unintended changes to motor position during a race run. For users of HoBao's flagship 1/7 and 1/8 on-road models, this upgrade component is essential for anyone serious about extracting maximum performance and consistency from their RC investment.

Frequently Asked Questions

• Which HoBao RC cars is this motor mount slider compatible with? — The HOP-0151 is specifically designed for the HoBao 1/7 Extreme VTE2-V2 On-Road Electric ARR and the HoBao Extreme VTE2 1/8 On Road EP models. These are high-performance on-road racing platforms that demand precision component matching. If you own a different HoBao model, you should verify compatibility before purchasing, as motor mount specifications vary significantly between platforms.
• What size motor does this slider accommodate? — This component is engineered specifically for 50mm diameter brushless motors, which are standard in 1/7 and 1/8 scale competitive on-road RC racing. The 50mm specification is critical — attempting to fit smaller or larger motors may result in improper mesh, mechanical interference, or unsafe operation.
• How much adjustment range does the slider provide? — The slider mechanism allows forward and backward motor positioning to fine-tune mesh with your transmission gears. The exact adjustment range depends on your chassis design, but the principle is to move the motor until gear contact is optimal without excessive force or noise.
• Is this suitable for beginners? — This is not a beginner component. Motor mount adjustment requires understanding of drivetrain mechanics, gear mesh principles, and how small positioning changes affect performance. This upgrade is best suited for experienced RC enthusiasts, competitive racers, and those with mechanical tuning experience. Beginners should focus on running their RC cars with factory-set components before attempting advanced tuning modifications.
• Will this improve my RC car's performance? — In the hands of someone who understands motor mesh and drivetrain tuning, yes. Optimising motor position can reduce noise, improve efficiency, and provide more consistent acceleration. However, improvements are subtle and incremental rather than dramatic. This is a precision tuning tool, not a horsepower upgrade.
• What tools do I need to install this? — You'll require a basic metric hex key set and potentially a metric wrench for fasteners, depending on your specific installation procedure. Consult your HoBao manual for detailed installation instructions and torque specifications.
• Can I fit this to a different brand RC car? — No. The HOP-0151 is engineered with specific mounting points and dimensions that match HoBao's modular design. Installing this on non-HoBao vehicles is not recommended and may not work correctly.
