Hey everyone,
I’ve finally crossed the finish line on a massive, highly involved custom build: my 1/72 scale "SeaCheyenne" (AH-56A) tailored for the United States Marine Corps!
This project took a full week of intense desk sessions, a huge contrast to my previous standard Army Cheyenne build which took only three days. Because this Marine variant required quite a bit of heavy scratch-building, part-grafting, and seam-fighting, it was definitely a testing process, but I’m incredibly proud of how this hypothetical prototype turned out.
BTW - I’ve only just started modelling and painting as a hobby. This is my 3rd build and I have more kits which I’ve purchased that I will be building up to Christmas.
FWI - I don’t own an airbrush (yet!) this was all hand painted
The Inspiration & Lore
The conceptual idea behind this fleet is heavily inspired by the real-world F-35 Joint Strike Fighter program. I wanted to treat the Cheyenne airframe as a universal multi-service air superiority attack platform.
Next up on my radar is an Air Force variant, completing the tri-service joint program idea!
The Scratch-Build & Custom Assembly
To transform a vintage Army design into an advanced, modern maritime attack platform, I raided my spares box and cross-kit components:
The Advanced Tail Fan: I completely cut away the standard tail rotor setup and grafted a heavy, multi-blade ducted pusher fan taken from my son's old Matchbox Skybusters drone toy. It gives the tail an advanced anti-torque profile.
Twin-Engine Housings & Details: I scavenged auxiliary engine exhausts, nacelle pieces, and weapon pylons from a Revell Snap-Tite F/A-18 Hornet and a Harrier GR9 kit to give the fuselage spine a heavily modified, beefier silhouette. I also managed to mount the Harrier's massive centerline gun pod right onto the underbelly for maximum firepower.
The Crew & Canopy Hack: The pilot and gunner figures, along with the custom-masked canopy frame, are secured down inside the cockpit tub using Magic-Tac repositionable glue. This allows me the flexibility to pop them out safely down the line if I want to re-use them for future projects!
Painting & Low-Vis Markings
Laying down a clean finish on light military greys is always a challenging hand-brushing process, but I stuck with a strict dry-palette setup using Revell 2-in-1 Thinner & Retarder alongside my Humbrol Gen 3 Acrylics to keep the brush strokes self-leveling and as thin as possible.
The Camouflage: The spine is finished in a bold Humbrol 164 Dark Sea Grey, contrasting cleanly against the lighter ghost-grey underbelly panels.
The Decals: Because I didn't want to use up my main waterslide sheets, I used the basic black-and-white stencils from the box (like the Jet Intake Danger arrows), and combined them with the pressure-sensitive peel-and-stick tactical markings from an Airfix Quickbuild F-35B kit. The "MARINES" and squadron labels are a perfect match since the real F-35B is a frontline Marine asset.
The Finishing Touch: The entire airframe was treated to an ultra-safe, water-based Humbrol Black and Smoke weathering powder wash mixed with a drop of water and a pin-prick of dish soap. It broke the surface tension on the intermediate gloss shield flawlessly, highlighting the engine grilles, rivet lines, and underbelly boxes. The whole model was sealed dead-flat using Humbrol Acrylic Clear Matt Varnish, leaving the canopy crystal clear while locking down the tactical look.
What’s Next on the Bench?
With the Marine variant in the books, I'm already planning my next two custom Cheyenne developments:
The sleek US Air Force Joint Fighter-inspired variant
A completely redesigned New-Generation US Army Variant. This one will be heavily inspired by modern compound programs like the Sikorsky Raider X and SB-1 Defiant—featuring a massive coaxial main rotor stack, a heavy rear pusher fan, and completely deleted stub wings for pure high-speed agility.
Let me know what you guys think of the custom mods, the payload, or the "What-If" concept! C&C is always welcome.
