Silver Four-Engine Aircraft - Complete Native Collection and Display

OVERVIEW
This complete four-engine aircraft is supplied as a static modelling and display subject. The inspected native FBX scene contains the assembled airframe, four propellers and nacelles, framed nose and cockpit glazing, wings, tail surfaces, undercarriage and exterior detail. The presentation shows a proposed silver metal finish with the supplied markings, dark propellers and glazed windows. It is a digital finish study, not a photograph of a printed model or a certification of a historical aircraft's colours. No working propellers, retracting gear or flying mechanism is claimed.

COMPLETE DOWNLOAD CONTENTS
The ZIP preserves all eleven unique supplied resources: FBX, OBJ, MTL, 3DS and STL alternatives, five texture images and one supplied reference image, plus a Blender inspection scene, complete 3MF and STL display derivatives, two locally prepared finished-display images, this project's English guide and an inventory. Relative resource links use opaque filenames and have been reopened in Blender. Necessary technical identifiers and supplied notices remain. The native variants have different units, tessellation and bounds; they are retained individually rather than presented as interchangeable copies.

DIMENSIONS AND SCALE
The derived 3MF and matching display STL have a selected maximum bounding extent of 250 mm across the wings. Their measured bounds are 250.00 mm wide, 176.38 mm long and 54.36 mm high in the illustrated static pose. This is a chosen miniature size, not a verified historical scale. The 3MF declares millimetres; STL has no unit declaration, so use millimetres for the derived display STL. Check each alternative native file's own dimensions before conversion. For another display wingspan use target wingspan divided by 250 times 100: a 200 mm target uses 80%. Small blades, aerials, frames and struts also shrink and may require a larger display or documented changes in a working copy.

GEOMETRY AND FILE LIMITATIONS
All 376,805 triangles from the inspected FBX scene are retained in the full display derivatives, including one zero-area source facet. The original STL alternative retains all 378,464 source facets, including duplicates and a degenerate facet; it differs from the FBX assembly. The original 3DS alternative uses another tessellation and coordinate layout. The complete native files are preserved alongside the prepared display copies. A viewing derivative may simplify geometry for loading; it does not replace the full downloads. The 3MF facet palette approximates the original colour maps, while the illustrations add a proposed silver surface response and glazing. Use the native UV maps and supplied reference resources for detailed finishing.

Static display derivatives verified at a selected 250 mm wingspan. Printing, fit, strength, working mechanisms and flight untested.
