Olive Twin-Engine Helicopter - Native Models and Upright Display

OVERVIEW
A detailed twin-engine attack-helicopter digital display model, with tandem cockpit, main rotor, tail rotor, landing gear, stub wings, external stores and mast-mounted radar geometry. The proposed finish combines olive-green body surfaces, dark rotor blades, subdued glazing and metallic mechanical details. This is an illustrative painted scale-model presentation, not a verified operational livery, manufacturer specification or working aircraft.

ORIGINAL AUTHOR AND RIGHTS
Original source author: Ishan / ishanat3ddesign. The plain author-credit note embedded in the supplied Blender scene is retained verbatim in the native file and as a separate text resource. Tomás Piernas is the publishing account and does not claim original design authorship. Free CC0 redistribution follows the uploader’s express authorization; legitimate credits and required technical identifiers remain.

FORMATS AND VARIANTS
The complete package retains Blender, FBX, OBJ with linked MTL, 3DS, Alembic, COLLADA DAE and X3D. It also preserves four distinct OBJ representations previously offered in the public packages, including the upright display version. Renaming changes public filenames and dependent resource paths while keeping numerical geometry and material values. Native variants are not silently substituted for one another. Public filenames use opaque identifiers; this does not make the design or its geometry anonymous.

PRESERVATION CHECKS
The renamed Blender scene was saved and reopened with all 93 mesh objects, its numerical mesh attributes, hierarchy and material graphs preserved. FBX, OBJ and Alembic each reopen with 93 meshes and 220,791 triangulated faces; 3DS reopens with 93 meshes and 220,789 triangles, matching its own original. These format differences are preserved. Alembic and 3DS copies retain their entire original binary contents. DAE and X3D retain their geometry, material data and internal references. No source scripts were executed.

MODEL PRESENTATION
Two large source reference or scenery planes remain in the native files but are excluded from the helicopter illustration. The presentation uses the actual remaining 91 source meshes, with a single uniform display transform. The helicopter is assembled and upright, with rotors and radar above the cockpit and landing gear below the fuselage. No missing surfaces are invented. The display plinth and workshop surroundings are illustrative, not included helicopter parts. Local PC AI supplies the surroundings; the actual model and its contacting base are protected in the composite.

SCALE AND UNITS

Untested source geometry. Confirm slicer units, manifoldness, intersecting surfaces and fine-feature thickness. The upright display OBJ is normalized for visualization; use full-resolution source geometry in the corrected package for fabrication checks. No verified physical scale, print settings, assembly fit or flight capability is claimed.
