Published description
OVERVIEW
This experimental coaxial-rotor aircraft miniature preserves the supplied fuselage, stacked rotor assembly, side propulsion housings, forward probe and twin-fin tail. Its cream/light-grey surfaces, red accents, dark rotor blades and existing markings follow the source appearance maps. The illustration presents the supplied aircraft upright as a finished display miniature. It does not establish flight capability, a working rotor mechanism or a tested physical build.
DOWNLOAD CONTENTS
The complete ZIP contains the native 3DS and FBX variants, the full OBJ assembly with its linked MTL, all six supplied JPEG/TGA appearance resources, an English preparation guide, a checksum inventory, CC0 information and the current presentation image. Extract the complete archive into one directory to preserve relative links. The OBJ is also available individually for technical viewing and download. A plain technical web view can differ from the textured illustration; mapped appearance remains available in the complete archive.
NATIVE VARIANTS AND PRESERVATION
The FBX and OBJ versions contain two mesh objects and 15,936 polygons. The 3DS variant retains its five source mesh objects and 17,595 triangles. These are distinct native representations, so their counts must not be treated as interchangeable or as printable part quantities. Every supplied variant is retained. The renamed 3DS was reopened with the official Blender 3DS reader; its geometry, UVs, material graphs, image pixels and sampled keyframe poses were compared. All non-string chunk payloads, including keyframe data, remain unchanged. FBX and OBJ geometry, UVs and material assignments were also checked by independent reopening.
All six appearance images retain their decoded pixels and orientation. JPEG annotations and TGA image-ID metadata are removed without repainting the supplied textures. OBJ material numbers, map options and linked dependencies remain intact. The source FBX refers to a separate take sidecar that was not supplied; no replacement animation file has been invented. Existing internal scene data remains retained.
DISPLAY AND ASSEMBLY
The supplied surface assembly does not include separate landing gear. The presentation therefore uses two small illustrative display supports beneath existing lower fuselage surfaces. Their contact positions were checked digitally by ray intersection. These supports and the plinth are scenery, are not supplied aircraft geometry and are not a physically tested stand design. No wheels, landing gear or mechanical attachments have been invented. The downloadable aircraft coordinates remain unchanged; the display applies one shared uniform scale and translation to the whole assembly.
