Yellow Light Helicopter - Display Model and Native Versions

OVERVIEW
This light utility helicopter display project preserves a complete airframe with the main rotor and enclosed tail rotor, original rotor blades, tail surfaces, landing skids, cockpit glazing, cabin, doors and existing exterior details. The finished illustration uses the supplied yellow body and dark glazing and original markings. It shows the model upright on an illustrative plinth in a hobby workshop. The image is a digital presentation rather than evidence of a physically printed, assembled or flight-tested miniature.

DOWNLOAD CONTENTS
Four ZIP entries retain the supplied package versions. They share two byte-distinct native resource families, each including an editable FBX and Blender scene and eighteen associated appearance resources. Each archive retains the OBJ viewing alternatives it previously contained. All four OBJ alternatives are also available individually. These are alternative versions rather than parts intended to be combined. Identical native resources are represented consistently across packages. Each manifest identifies neutral filenames, roles and integrity hashes. An unbound reference photograph remains archived privately.

PRESERVATION CHECKS
Both FBX versions are independently reopened before and after neutralization. Both Blender copies are saved and reopened with Blender 5.2. Each native family retains forty mesh objects. Numerical geometry, UV coordinates, material assignments, node relationships, hierarchy and decoded bound-image pixels are compared. Previously unresolved texture paths are restored only to supplied resources using format-aware path-field changes; the remaining non-path native data are checked separately. All eighteen appearance resources in each native family retain their decoded pixels and effective orientation.

All four OBJ alternatives retain their original numeric vertex, face, normal and smoothing statements. The selected technical view has forty objects and 312,860 triangles; older alternatives contain twenty-one or twenty-three objects. These untextured views differ in detail and are not equivalent to the full native scenes. A lighter browser copy is for navigation; full downloads remain unchanged. Native archives supply the mapped finish shown in the cover. Scene-object counts do not establish printable part counts, mechanical fit or working articulation. Original files and preservation receipts remain archived privately.

PRINTING PREPARATION - UNTESTED
Open a working copy and confirm units, intended dimensions and printer build volume. Inspect thin rotor blades, rotor hubs, tail edges, landing-gear legs, glazing boundaries, small mounted details, open boundaries and intersecting surfaces. A complete-looking model can still need watertight repairs, thickening, separation or hollowing. Perform those changes only on a copy after examining the actual geometry. Rotor movement, balance, strength, articulation, flight capability and powered operation have not been verified. Do not treat a decorative surface mesh as an airworthy structure.

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.

Prepared for display and download. No physical print has been certified.
