Update 30th June 2026: Build and Fly IronBear Mi17 with FlyWing Small Mechanics.
Yes now, if you do not have a FlyWing FW450 V3 helicopter, but have flywing Small mechanics (Used in flywing Huey Uh1, Bell 206, Bo105, UH60 Helicopters), with the new small mechanics fitting parts (Base plate, top mech joiners) I just released, you can build, assemble and fly this legendary Gunship military transport RC helicopter with small mechanics too. and these parts are free of cost if you have already purchased the Ironbear before the update.
Weeks of intensive design. Sleepless nights. Days of printing, testing, reprinting, re-testing, and occasionally questioning my own life choices at 3am with filament in my hair. All of it — every single hour — poured into one machine.
AliShanMaoRC proudly presents the IronBear X470, a Mi-17 inspired, highly scaled Gunship Military RC Helicopter Fuselage that will make you question everything you thought was possible from a 3D printer. Spoiler: your printer is fine. This is just what passion, experience, and a stubborn refusal to compromise on scale detail actually looks like.
Built on everything I learned from designing the WarKroc Mi-24, the SkyMule CH-53, and the Airfox H125M — IronBear is the sum of all of it. Every mistake I made before, every lesson I carried forward, every detail I wished I had done better on previous designs — I put it all right here, into this one helicopter.
What IronBear Brings to Your Flying Field
Fewer parts, more scale. I redesigned the entire philosophy. Fewer individual parts to print and manage, with more scale detail built directly into the fuselage itself. No hunting for tiny printed goodies to glue on separately. The detail is already there, waiting for your paint.
Prints strong, not just pretty. Every part is oriented and designed so that when you print it correctly, it prints in the strongest possible direction for flight stress loads. This is not a display model. This helicopter is built to fly, and the parts are engineered to take the beating that comes with it.
Assembly that won’t test your patience — much. Slide in your FlyWing FW450L V2 or V3 mechanics, lock with a screw, drop two screws to secure mechanics top, locked and loaded. Pull your tail rotor cable through the tail boom, connect it to the tail motor, install the tail rotor with 3 screws. Done. The only part that will take you extra time is routing that tail cable through the boom — and honestly that is just the price of having a properly scaled tail boom. Everything else goes together like it was meant to be together, because it was.
Sliding side doors and snap-lock rear cargo door. Your toy soldiers finally have a proper home. The rear cargo door gives your favourite USB-C cable easy access to the flight controller for parameter setup anytime. No disassembly required. IronBear thought of everything.
A cockpit worth looking into. Scaled instrument panels and seats inside the cockpit. Your dummy pilots are already grinning. They know they landed in something serious.
Realistic landing gear with free-wheeling wheels. Taxi your IronBear on the ground like the real thing. Want a steerable nose gear so you can taxi like an absolute boss? Drop your request in the comments. If enough of you want it, I will make it happen as an add-on.
Ordnance that demands respect. Twin rocket pods. Twin 6-round Hellfire payloads — that is 12 Hellfires, yes you read that correctly. And those four-barrel 50mm cannons that nobody in the RC world can ignore. Local pigeons have already filed for emergency relocation permits. The full military weapons load attaches and detaches cleanly from the scaled side wings with realistic structural supports, just like the real helicopter. Want different weapons or mission role goodies later? Tell me in the comments. IronBear’s weapons rails are ready for whatever comes next.
Generous airflow throughout. Top vents, windows, and doors keep your beloved electronics cool during flight. Because a helicopter this good deserves electronics that survive the summer.
A Word Before You Start Your Build
If you tell me you built your IronBear X470 in a single day, I will respectfully inform you that you are not a real RC pilot and definitely not a real RC helicopter lover.
This helicopter deserves your time. The mechanics installation is straightforward, the assembly is pleasant — I designed it that way on purpose. But to make IronBear look exactly like the battle-hardened gunship living in your head, you need to spend real time on paint, on weathering, on decals. Build it right. Build it with love and patience.
Because here is what happens when you do: the moment IronBear lifts off at your RC flying field, every other pilot will stop flying. They will walk over. They will stare. And they will ask you — where did you get that?
That is your moment. Smile with pride and point them to https://alishanmaorc.com

A Note on Protecting Original Design Work
IronBear X470 is a protected original design by AliShanMao RC.
Please do not share, copy, or distribute your purchased STL files. I know it feels harmless to send a file to a friend who loves the helicopter — but every shared file is a purchase that never happened, and behind every purchase that never happens is a designer who spent sleepless nights building something beautiful and cannot pay his bills. That designer is me.
If your friend loves IronBear, send them the link. If you want to gift it to someone, purchase a copy for them. That one decision keeps creators like me going — and keeps new designs coming.
By completing your purchase you agree to our Terms and Conditions, NDA for Digital Products, and Returns and Refund Policy available at alishanmaorc.com.
If you ever spot unauthorised use of IronBear or any AliShanMao design, please report it immediately to: ali@alishanmaorc.com | shopcreatec@gmail.com | alishanmao@gmail.com
Why Your Purchase Matters More Than You Think
Behind IronBear is not a factory. It is one person, a 3D printer running at 3am, a workbench covered in test prints, and a genuine obsession with bringing something nobody else has built into the hands of RC pilots who deserve better than what the market offers.
When you choose to purchase an original design instead of downloading a pirated file, you are saying something important:
“I value the work. I respect the craft. I believe in the creator.”
That belief is what makes the next design possible. And the one after that.

Mechanics Compatibility
IronBear X470 is designed and tested specifically for FlyWing FW450L V2 and V3 mechanics, without tail boom.
Important note on tail rotor cables: Because IronBear uses its own scaled tail boom, you will need to extend your tail rotor cable length. If you have already built a SkyMule CH-53 or WarKroc Mi-24 from AliShanMao RC, you have already done this before. Welcome back, you know the drill.
If you are new to this, do not worry — it is a straightforward process and covered in the assembly video series on my YouTube channel.
FlyWing tail rotor: The updated 3-screw silver tail rotor is the one to use. You know the one.
What about smaller FlyWing mechanics? I have had requests from FlyWing Huey UH-1, Bell 206, BO105, and MH-60 helicopter owners who want to build an IronBear with their existing smaller mechanics. If enough of you drop me an email at ali@alishanmaorc.com expressing interest, I will develop a separate small mechanics compatibility kit for IronBear. It will be sold as a separate add-on kit. Let your voice be heard — your emails make designs happen.
At any time, if you need help, just click on floating alishanmao genie on https://alishanmaorc.com and get in touch with me. I would love to guide you to build your helicopter the right way.
Printer Requirements
Minimum bed size: 220 x 220 x 230mm Any FDM printer that meets this bed size will handle IronBear just fine.
Tested and working great on: Bambu X1C, Bambu A1, Bambu P1S, Creality Ender 3 V3 Plus (my personal favourite), and other Creality FDM printers. If your printer fits the minimum bed size, you are good to go.
Filament Recommendations
PLA is highly recommended for easiest printing and best results. White, grey, or black PLA tends to print most consistently — coloured filaments from various brands can sometimes have their quirks.
That said, if you trust your PETG or prefer another filament your printer handles well, go for it. Printing is your choice and your adventure. I just recommend what works best in my experience.
Stick with your trusted filament brand. A good filament you know beats an unknown brand every time.
Approximate filament usage: Based on my Bambu X1C with the included 3MF settings, the full kit uses approximately 833 grams of filament and prints in approximately 35 hours. Your print time may be shorter or longer depending on your printer speed settings. Plan accordingly, brew some coffee, and enjoy watching layers turn into a helicopter.
Finished fuselage weight: Approximately 730 grams fully assembled — light enough to fly beautifully, strong enough to take the beating of real RC helicopter flights. That is what designing parts in the right print orientation does for you.

Assembly & Build Guide
A full 2 to 3 part video series covering kit introduction, fuselage assembly, and FlyWing mechanics installation is available on my YouTube channel at https://www.youtube.com/@alishanmao
Watch it before you start your build — it will make your assembly experience smooth, clear, and genuinely enjoyable.
How long will the build take? Fuselage assembly and mechanics installation can absolutely be completed in a single dedicated day. However — and I say this with love — if you want IronBear to look like the battle-hardened gunship helicopter living in your head right now, that takes longer. Paint, weathering, decals, details — that is where the real time goes, and that is where the real reward comes from. Build it right. Every flight will remind you that you did.
Frequently Asked Questions
Q: Which mechanics does IronBear X470 fit? A: FlyWing FW450L V2 and V3 mechanics only, without tail boom. Tail rotor cable extension is required — covered in the assembly video series on YouTube.
Q: What printer do I need? A: Any FDM printer with a minimum 220 x 220 x 230mm build volume. Bambu X1C, A1, P1S, Creality Ender 3 V3 Plus, and other standard FDM printers all work perfectly.
Q: Can I print this in PLA? A: Yes and it is what I recommend. PLA gives you the easiest printing experience and excellent results. White, grey, or black PLA performs most consistently.
Q: What filament brand should I use? A: Use the brand you already trust and know. A reliable filament you have experience with will always outperform an unknown brand. PLA is recommended, PETG and other filaments work too if your printer handles them well.
Q: How much filament will I need? A: Approximately 833 grams for the full kit based on my Bambu X1C with the included 3MF settings. Budget around 900 grams to be safe and have a little extra on the spool.
Q: How long will printing take? A: Approximately 35 hours on a Bambu X1C with my suggested 3MF settings. Other printers and speed settings will vary. Plan for a full weekend of printing minimum.
Q: How long does assembly take? A: Fuselage assembly and mechanics installation in one focused day is very achievable. Full build with painting and detailing — that depends entirely on how much love you are willing to put into it. The more the better.
Q: What file formats are included? A: All parts are provided in STL format. A complete 3MF project file with best print orientations pre-configured for Bambu X1C is also included in the bundle. If your slicer cannot open 3MF files, use it as a visual orientation reference.
Q: Will this work with mechanics other than FlyWing FW450L V2/V3? A: Not without significant modification. If you want to see smaller FlyWing mechanics compatibility developed, send an email to ali@alishanmaorc.com. Enough requests and I will make it happen as a separate add-on kit.
Q: Do design updates cost extra? A: Any update or improvement I make to existing IronBear parts is free for full kit purchasers. New add-on packs, accessories, and future goodies packs are separate products.
Q: I missed my download window. What do I do? A: Email ali@alishanmaorc.com. If your files show as not downloaded, I will sort it out for you immediately. No drama, no arguments.
