Overview
The Blade Main Rotor Head Block (Model Z-BLH3404) is an essential replacement component for RC helicopter enthusiasts in the UK who operate Blade 180 CFX, 130 S, or 150 S models. This precision-engineered rotor head block is a critical part of your helicopter's main rotor system, responsible for controlling blade pitch and maintaining stable flight dynamics. Whether you are recovering from a crash, performing scheduled maintenance, or upgrading your RC heli setup, this genuine Blade component ensures your aircraft performs at its best.

Key Features
- Genuine Blade Manufactured Component — This is an authentic OEM (Original Equipment Manufacturer) part produced by Blade, ensuring it meets all design specifications and tolerances required for your helicopter's rotor system to function correctly and safely.
- Compatible with Multiple Blade Models — The Z-BLH3404 is engineered to work seamlessly with the Blade 180 CFX, 130 S, and 150 S helicopter models, making it a versatile spare part for enthusiasts operating multiple Blade platforms.
- Includes Dampers for Vibration Control — The package comes with two dampers that work in conjunction with the rotor head block to absorb vibration and reduce stress on the main rotor system, contributing to smoother flight characteristics and extended component lifespan.
- Complete Installation Hardware — A 2mm machine bolt is included in the package, providing everything you need for straightforward installation without searching for compatible fasteners.
- Essential Maintenance Part — Keeping this component in your crash kit alongside main blades, shafts, and linkage sets allows you to get your RC helicopter back in the air quickly following an accident or when performing routine maintenance.
Technical Performance
The Main Rotor Head Block is the mechanical interface between your helicopter's main shaft and the rotor blades, translating servo inputs into blade pitch changes that control flight attitude and altitude. Manufactured from durable materials selected for strength-to-weight ratio and resistance to the cyclic stresses of helicopter flight, this component maintains tight tolerances that are critical for smooth operation. The inclusion of two dampers helps isolate vibration from the rotor system, protecting other components and improving overall flight stability. The 2mm machine bolt is precision-engineered to withstand the forces generated during normal and aggressive flying manoeuvres. For UK-based RC helicopter pilots operating Blade models, maintaining the rotor head block in optimal condition is fundamental to safe, predictable flight performance and longevity of the entire helicopter platform.

Frequently Asked Questions
- When should I replace my Main Rotor Head Block? — You should consider replacing your Main Rotor Head Block if you notice excessive play or looseness in the rotor system, if the block shows visible cracks or damage following a crash, or as part of routine maintenance if you fly regularly. Many experienced RC helicopter pilots keep a spare in their crash kit for rapid field repairs.
- Is this suitable for beginners? — Whilst the Main Rotor Head Block is a genuine spare part rather than a complete helicopter kit, it is suitable for beginner and intermediate RC helicopter pilots who are familiar with basic helicopter maintenance and assembly. If you are new to RC helicopters, we recommend consulting your helicopter's instruction manual or contacting our expert team for guidance on installation.
- Will this work with my Blade helicopter? — The Z-BLH3404 is specifically designed for the Blade 180 CFX, 130 S, and 150 S models. Before purchasing, confirm your helicopter model matches one of these three specifications. We recommend matching part numbers to your helicopter's manual to ensure a perfect fit.
- What tools do I need to install this part? — Installation typically requires basic tools such as hex keys or Allen wrenches appropriate for your helicopter's fasteners, and possibly a small screwdriver. Refer to your helicopter's instruction manual for specific installation procedures and torque specifications. We recommend using medium threadlock on metal-to-metal screws during installation to prevent vibration-induced loosening.
