Overview
The Blade Main Blades: 180 CFX, 150 S (Z-BLH3402) are genuine OEM replacement main rotor blades designed specifically for collective-pitch RC helicopters. Whether you're an experienced RC helicopter pilot in the UK or a newcomer exploring the world of RC flight, these main blades are an essential spare part to keep your model performing at its best. As the rotor blades are among the most frequently replaced components on any RC helicopter due to normal wear and damage from crashes or hard landings, having a quality replacement pair on hand ensures you can keep your aircraft in the air without unnecessary downtime.
These authorised Blade replacement blades represent a straightforward, practical choice for routine maintenance and repairs on small collective-pitch models. The Blade 180 CFX is a popular platform in the RC helicopter community, renowned for its responsive handling characteristics and reliable performance. By choosing genuine Blade OEM spares rather than aftermarket alternatives, you're investing in components engineered to exacting standards by the helicopter's manufacturer, ensuring consistent aerodynamic performance, balanced flight dynamics, and long-term reliability. RC Model Shop stocks these genuine blades in the UK, making it easy for hobby pilots to source authentic replacements without overseas shipping delays.
When your current blades become worn, develop cracks, or suffer damage from impact, replacing them with this genuine Blade set restores your helicopter to factory performance specifications. The clearly marked identifiers make matching the correct part for your specific model straightforward, helping you avoid compatibility issues and ensuring you have the right item in your spares box when you need it most.
Key Features
- Genuine OEM Blade Spare Parts — As an authorised Blade replacement component, these blades are manufactured by the original equipment maker to exact specifications, guaranteeing aerodynamic balance, structural integrity, and reliable performance that matches your helicopter's original blades perfectly.
- One Pair of Main Rotor Blades — The package includes a complete set of main blades, providing everything you need to restore full rotor functionality after wear or damage, with no additional blade purchases required for a complete replacement.
- Designed for Blade 180 CFX Models — These blades are specifically engineered for the Blade 180 CFX collective-pitch helicopter platform, ensuring perfect fit, balance, and aerodynamic compatibility with your aircraft's rotor head and control system.
- Easy Part Identification — The clearly listed part number (BLH3402) and manufacturer identifier (605482556375) make it simple to confirm you have the correct replacement, reducing the risk of ordering wrong parts and ensuring compatibility with your helicopter model.
- Routine Maintenance Essential — Main rotor blades naturally wear over time with regular flight operations, develop micro-cracks from landing impacts, or suffer damage in crashes, making these replacements a practical necessity for any serious RC helicopter pilot who wants to maintain consistent flight performance.
- Reliable Performance Restoration — Replacing damaged or worn blades with these genuine Blade components restores your helicopter's original handling characteristics, response rate, and stability, allowing you to fly with confidence knowing your aircraft is performing at its intended specification.
Technical Performance
The Blade Main Blades: 180 CFX, 150 S are engineered to deliver consistent aerodynamic performance across the operating envelope of small collective-pitch RC helicopters. These replacement blades are manufactured to match the original factory specifications of the Blade 180 CFX platform, ensuring that rotor balance, pitch response, and aerodynamic efficiency remain unchanged when you install them. The blades maintain precise weight distribution and dimensional tolerances required for smooth, vibration-free rotation, which is critical for stable hovering and responsive pitch control during flight. Built to withstand the stresses of normal RC helicopter operations including pitch changes during collective manoeuvres, autorotational descents, and dynamic 3D flying, these blades provide the structural integrity necessary for reliable long-term service. The genuine Blade engineering ensures that your helicopter's control response remains predictable and reliable, whether you're flying casually in the park or pushing the envelope with advanced aerobatic manoeuvres. Replacing worn or damaged blades with these OEM components is far more effective than attempting to repair cracked blades or continue flying with unbalanced rotors, which can cause excessive vibration, unpredictable flight behaviour, and potential rotor head damage.

Frequently Asked Questions
- Are these genuine Blade replacement blades or aftermarket copies? — These are genuine OEM Blade spare parts manufactured by the original equipment maker to exact specifications. The part number BLH3402 and manufacturer identifier 605482556375 confirm authenticity, ensuring you receive components engineered and quality-controlled by Blade themselves rather than third-party alternatives that may compromise performance or durability.
- Which Blade helicopter models do these blades fit? — These main blades are specifically designed for the Blade 180 CFX collective-pitch RC helicopter. It's important to verify your model matches the 180 CFX designation before ordering, as using blades designed for different rotor head sizes or control systems will result in poor fit, imbalanced rotation, and unreliable flight performance.
- How often should I replace my RC helicopter blades? — Main rotor blades should be inspected regularly for visible cracks, splintering, or delamination. Any damage requires immediate replacement to prevent rotor imbalance and unpredictable flight behaviour. Even without visible damage, blades develop micro-cracks over time with normal use, and most experienced pilots replace their blades annually or every 50–100 flight hours, whichever comes first.
- What's the difference between genuine Blade blades and cheaper aftermarket alternatives? — Genuine Blade blades are manufactured to precise tolerances, ensuring consistent weight distribution, aerodynamic balance, and structural integrity. Aftermarket alternatives may have dimensional inconsistencies, uneven weight distribution, or inferior materials that lead to vibration during flight, poor handling response, and premature failure. Genuine components cost slightly more but deliver superior performance and reliability.
- Do these blades come pre-balanced? — Yes, genuine Blade OEM blades are manufactured to factory specifications and come balanced from the maker. However, before installation, it's good practice to inspect them visually for any shipping damage and ensure your rotor head itself is clean and in good condition, as rotor head wear can affect overall balance even with perfectly manufactured blades.
- Can I use these blades on other Blade helicopter models? — No, rotor blades are specifically designed for their intended helicopter model. Using these 180 CFX blades on different rotor head sizes will result in poor fit, dangerous vibration, and unreliable flight performance. Always verify your helicopter model matches the blade designation before purchasing.
- Is this suitable for beginners? — These are replacement spare parts designed for anyone operating a Blade 180 CFX helicopter. Beginners should keep a spare pair on hand because crashes and blade damage are common during the learning phase, and having replacements available means less downtime and more practice flying.
