FlyWing EC135 Secrets — 10 Things You Can’t Ignore!

Hey everyone! I just got my hands on the FlyWing EC135, and I want to share what it’s really like after opening the box and flying it around a bit. This bright yellow heli looks stunning at first glance, but the real magic lies in the details and how it flies. Here’s my full breakdown based on actual experience:

1.Full Fiberglass Body — No Cheap Plastic Here

Right when I picked it up, I could feel the difference. Unlike the usual plastic shells, this whole fuselage is made of fiberglass, giving it a solid, hefty feel. It’s smooth but firm, and it honestly feels like a serious piece of equipment—not a toy. Compared to plastic, it’s way more durable and has that premium vibe.

2.Real Engraved Rivets — Not Just Stickers or Paint

If you’re into authenticity like me, you’ll appreciate this: the rivets aren’t just painted on or decals slapped over. They’re actually engraved into the fiberglass surface, so you can feel the tiny bumps when you run your fingers over them. This adds a whole new layer of realism that most models just can’t match.

3.Unique Ducted Multi-Blade Tail Rotor

The tail rotor is something special. Instead of a traditional two-blade setup, the EC135 uses a multi-blade ducted fan design. When it spins up, the sound is more like a turbine than a typical tail rotor buzz. It’s a cool, futuristic sound that really adds to the whole experience and makes you feel like you’re flying a real turbine heli.

4.Full-Metal 4-Blade Rotor Head with Quick-Release Blades

The rotor head is fully metal, which not only looks sleek but makes it super durable. Installing or removing the blades couldn’t be easier — just push them in and twist slightly to lock, no tools needed. This quick-release design saved me so much time when swapping blades for repairs or upgrades.

5.Advanced H1 Flight Controller + GPS for Rock-Solid Stability

This is where the EC135 shines for pilots of all levels. The H1 flight controller combined with GPS allows the helicopter to hover hands-free. I tested it by taking my hands off the sticks, and it just stayed put perfectly steady. It also supports automatic figure-8s and circle flights, which is great for relaxing and enjoying smooth flying without constant input.

6.Spacious Cabin Fits Large Batteries up to 5200mAh

Opening the bottom hatch, I was surprised by how roomy the battery compartment is. The included 5000mAh battery gave me about 15 minutes of solid flight, but I could easily fit a 5200mAh battery I had on hand to get even longer airtime. The space is generous compared to similar models, so no worries about battery size.

7.Transmitter Supports English + Beginner Tutorials

The remote control is thoughtfully designed in English easily. Plus, it comes loaded with beginner tutorials covering everything from powering on, calibrating, to flying basics. Perfect if you’re new to RC helicopters and want to learn step-by-step.

8. Treat With Care – Handle the Blades Safely

The rotor blades are designed with a NACA airfoil and reinforced with a metal core, making them extremely sharp. Before powering on the EC135 helicopter, always ensure there is a minimum 3-meter (10-foot) safety zone around it. Never reach into the rotor area when the blades are spinning.

⚠️ This is not a toy.
Always wear protective gloves when handling the blades. Children must be closely supervised by an adult at all times.

9. Don’t Crash! How to Avoid Rookie Mistakes with Your FLYWING RC Helicopter EC135

Before your first flight, take a moment to understand the radio controller and flight mode setup to avoid unnecessary crashes. By default, the controller is set to Mode 2 (throttle on the left). If you wish to switch to Mode 1 (throttle on the right), you’ll need to press a specific combination of buttons — a setup often preferred by club-level pilots. However, beginners are strongly advised to stick with the default Mode 2 until they are fully familiar with the controls. Additionally, be careful with the flight mode switch: the middle position is for normal GPS mode, the down position initiates a spiral pattern, and the up position triggers an H-shaped flight route. These functions are powerful but can be accidentally triggered, leading to mid-air shutdowns or crashes. For safety, many users tape the switch in place or use a protective cover — one crash report even linked an accident to an accidental downward toggle.

When it comes to flight modes, always start in GPS mode (solid green light). Do not jump directly into 3D mode (blue light) unless you’re experienced. If using 3D mode, make sure to set a 3D safety threshold — for example, 8 meters — so the system can automatically switch back to a stable mode if the aircraft drops too low. Also, note that when you activate Return-to-Home, the helicopter returns to the original takeoff point, not the remote controller’s location. Ensure the takeoff area is wide and free of obstacles to prevent collisions during return.

Good news for beginners: the GPS module requires no manual calibration. The M10 GPS system automatically learns its position after power-on. During testing, users were able to take off directly after installing the battery, with accurate GPS lock. Just make sure to wait until the status light turns green (usually within a minute) before taking off.

10. Never Let Your Battery Run Out! Here’s Why One 5000mAh 4S Battery Isn’t Enough

A single 5000mAh 4S battery only lasts about 20 minutes in the air. If you’re a beginner and only have one battery, you’ll be dealing with constant interruptions. We highly recommend getting at least two batteries and using a B6 Néo charger for your FLYWING EC-135 RC heli— it charges way faster than the original one.

Heads up on charging: The original charger has a Chinese plug, but if you buy from SK, they throw in a free EU adapter, so no worries there. Also, if your battery voltage drops below 3.6V per cell, the heli will automatically return home. So, don’t wait till the battery’s dead — land early when power’s running low.

Where Does the FlyWing EC135 Fit in Your Flying Journey?

The FlyWing EC135 is a 470-class helicopter — which means it’s larger and more powerful than your average beginner heli, but it’s not as intimidating as the massive professional models you see at big shows. It hits a sweet spot for intermediate pilots who want more realism and functionality without diving headfirst into the complex world of large-scale helis. It’s not just about the size — it’s about how it flies. This heli is for people who care about build quality, flight performance, and visual realism. And that really shows the moment you take it outside and power it up.

For my first flight, I started by opening the bottom latch to install the battery — it’s snug but roomy enough to fit a 5000 or even 5200mAh pack. Then I powered on the transmitter and made sure to switch to GPS flight mode. That step is key — without GPS mode, the heli won’t arm or take off.

Once connected, I waited for the H1 flight controller’s LED to turn from flashing yellow to solid green, which indicates that GPS satellites are locked in and the system is ready to go.

From there, I did the outward-stick arming gesture and watched the blades slowly start spinning. Then I tapped the start button — and the EC135 smoothly lifted off the ground.

The hover was incredibly stable. I literally let go of the sticks for a moment just to test it, and the heli held its position perfectly. It felt like flying a DJI drone in terms of GPS stability, but with the look and feel of a real-scale helicopter.

Next, I flicked the switch for figure-8 mode. The EC135 performed the maneuver gracefully, tracing the flight path with no input from me — smooth and confident. And when I triggered the return-to-home function, the helicopter gently flew back to the launch point, rotated to face the original direction, descended, and shut off the rotors automatically. Super satisfying and stress-free.

Final Thoughts

FlyWing EC135 feels like a pro-level machine wrapped in a user-friendly package. It’s built tough, packed with smart flight tech, and offers a flying experience that’s both immersive and stable. While beginners might find it a little challenging at first, the GPS and flight controller make learning less stressful. If you’re looking for a serious mid-sized heli that’s more than a toy but not overwhelmingly complex, the EC135 is a top pick. It strikes the perfect sweet spot for hobbyists who want realism, reliability, and fun.

Happy flying!
