If you're searching for a premium 800-class RC helicopter, you've probably noticed one thing: most large-scale models on the market are sold as kits that require extensive assembly, tuning, and setup before they're ready to fly.
For many RC helicopter enthusiasts, that's part of the hobby. But for pilots who want professional performance without spending weeks building an aircraft from scratch, the options have been surprisingly limited.
That's exactly why the RAZORDON EC135 800-Class 2.4G 6CH Scale RC Helicopter with H1 PRO Flight Controller & GPS Positioning (RTF) was created.
As one of RAZORDON's largest and most advanced scale helicopters to date—and one of the few 800-class Ready-to-Fly (RTF) scale RC helicopters available—it combines premium components, intelligent GPS flight assistance, and exceptional scale realism in one complete package.
Whether you're upgrading from a 500 or 700-class helicopter or adding a flagship model to your collection, here's everything you should know before making your decision.
Why Choose an 800-Class RC Helicopter?
Moving to an 800-class RC helicopter isn't simply about flying a larger aircraft—it's about experiencing a completely different level of realism and performance.
Compared with smaller helicopters, an 800-class platform offers several important advantages:
- Greater in-flight stability thanks to the larger rotor disc
- Better visibility at longer distances
- Increased resistance to wind during outdoor flights
- Smoother and more scale-like flight characteristics
- A stronger visual presence both on the ground and in the air
For pilots who enjoy scale flying rather than aggressive 3D aerobatics, an 800-class helicopter provides a flight experience that closely resembles the behavior of a full-size helicopter.
The EC135 platform takes those advantages even further with a carefully engineered fiberglass fuselage and professional-grade flight electronics.
One of the First Ready-to-Fly 800-Class Scale Helicopters
One of the biggest challenges in the large-scale RC helicopter market is accessibility.
Many helicopters in this size category are sold as:
- Airframes only
- ARF (Almost Ready to Fly)
- Kit versions requiring electronics installation
- Models that require extensive tuning before the first flight
The RAZORDON EC135 changes that experience.
It arrives as a Ready-to-Fly package, featuring factory-installed electronics, a professionally integrated flight control system, and carefully selected components that work together right out of the box.
Instead of spending countless hours sourcing servos, ESCs, motors, and flight controllers, pilots can focus on what matters most—flying.
This approach makes the EC135 an excellent choice for experienced hobbyists looking for a premium scale helicopter without the complexity of a traditional kit build.
Premium Components from Trusted Brands
Performance begins with quality hardware, and the EC135 is equipped with components trusted by RC helicopter enthusiasts worldwide.
The helicopter features:
- Align 800MX 490KV Brushless Motor
- Hobbywing 180A Brushless ESC with Cooling Fan
- Carbon Fiber 750mm Main Rotor Blades
- KST 915 Digital Servos
- CNC-Machined DFC Rotor Head
- Metal Servo Arms
- Torque Tube Tail Drive
Rather than relying on generic electronics, every major component has been selected to deliver smooth power, precise control, reduced vibration, and long-term reliability.
This combination creates a helicopter that feels refined from the moment it lifts off.
Advanced H1 PRO Flight Controller with GPS Positioning
One of the most important upgrades on the EC135 is the FLYWING H1 PRO Flight Controller.
Unlike traditional flybarless systems that rely entirely on pilot input, the H1 PRO introduces intelligent flight assistance without sacrificing precision.
Features include:
- GPS Position Hold
- BeiDou + GPS Dual Satellite Positioning
- Altitude Hold
- Automatic Hover
- Self-Level Stabilization
- CAN Bus Communication
- Fast Satellite Acquisition
- Enhanced Anti-Interference Performance
When the control sticks are released, the helicopter automatically maintains its position and attitude, significantly reducing pilot workload.
For larger helicopters, this added stability increases confidence during takeoff, landing, and scale flying.
Scale Realism That Stands Out
The EC135 isn't just designed to fly well—it's designed to look authentic from every angle.
The fiberglass fuselage accurately recreates the clean lines of the full-size EC135, while numerous scale details enhance its realism, including:
- Opening cockpit doors
- Illuminated cockpit
- Navigation lights
- Detailed instrument panel
- Realistic windows and windshield
- Accurate exhaust detailing
Whether displayed in your workshop or flying at your local RC field, the EC135 immediately captures attention.
Built for Smooth, Stable Flight
Large helicopters demand a power system capable of delivering consistent performance.
The EC135 uses:
- Dual 5000mAh 6S LiPo batteries
- Align brushless motor
- Hobbywing 180A ESC
- Carbon fiber rotor blades
The dual-battery configuration improves efficiency while providing stable voltage throughout the flight.
Combined with the precision CNC DFC rotor head, vibration is minimized, resulting in smoother handling and improved mechanical durability.
Ready to Fly Means More Time in the Air
Unlike many large-scale helicopters that require weeks of assembly and tuning, the EC135 is supplied as a complete Ready-to-Fly system.
Included with the helicopter are:
- FlySky FS-i6S Transmitter
- FlySky iA6B Receiver
- Dual-channel 6S Charger
- Installed H1 PRO Flight Controller
- Factory-installed Power System
The helicopter and batteries are shipped separately to comply with international transportation regulations, ensuring safe delivery worldwide.
Who Is the EC135 Designed For?
The RAZORDON EC135 is best suited for:
- Experienced RC helicopter pilots
- Scale helicopter enthusiasts
- Collectors looking for a flagship model
- Pilots upgrading from 500 or 700-class helicopters
- Hobbyists who want professional performance without building a kit
While the H1 PRO flight controller provides intelligent stabilization, this is still an 800-class high-performance RC helicopter and is recommended for pilots aged 16 and above with appropriate flying experience.
Why the RAZORDON EC135 Stands Out
The RAZORDON EC135 represents more than just another scale helicopter—it reflects a shift toward making large-scale RC helicopters more accessible.
By combining premium components, intelligent flight technology, authentic scale detailing, and Ready-to-Fly convenience, it removes many of the traditional barriers associated with owning an 800-class helicopter.
Instead of spending weeks assembling a complex kit, pilots can enjoy a professionally integrated aircraft that's ready to deliver an exceptional flying experience.
For enthusiasts looking to step into the world of premium scale helicopters, the EC135 offers a compelling balance of realism, technology, and performance.
Final Thoughts
The RAZORDON EC135 800-Class 2.4G 6CH Scale RC Helicopter with H1 PRO Flight Controller & GPS Positioning is built for pilots who expect more from their RC aircraft.
With its fiberglass scale fuselage, advanced GPS-assisted flight control, premium brushless electronics, carbon fiber rotor blades, and Ready-to-Fly design, it delivers the look, feel, and performance of a true flagship model.
If you've been waiting for an opportunity to own a large-scale RC helicopter without the complexity of a traditional kit, the EC135 deserves a place at the top of your shortlist.
