Extra 300 digital aircraft model. Simplified Extra 300 airframe mesh with fuselage, low wing, defined control surfaces and tail. The front cowl is open. No motor, propeller, canopy glazing or landing gear is supplied in this mesh.

PACKAGE CONTENTS
The ZIP contains the original STL mesh and an English source-file guide. The same STL is supplied separately for the web viewer. All added filenames are in English and mapped to the original labels in the guide. Original source bytes and numerical coordinates are preserved. This is a digital design asset; no verified multipart printable aircraft kit is claimed.

SOURCE VERIFICATION
The binary STL triangle count was validated and the supplied geometry imported into local Blender for visual inspection. Source units and physical dimensions have not been independently confirmed. The source label identifies the design represented.

PREPARATION AND USE
Suitable for digital display, rendering and further model preparation. Inspect topology, thin walls, watertightness, disconnected surfaces, supports, orientation and dimensions before fabrication. Physical printing, component fit and functional RC operation have not been tested. Hardware, electronics and any components absent from the source mesh are not included.

ORIGINAL MESHOPIA PRESENTATION
It illustrates a proposed finish and does not document a manufactured or flight-tested aircraft.

ADDITIONAL NATIVE CAD SOURCE
A separate English-named ZIP now adds the original SolidWorks SLDPRT source and a filename mapping guide. Native bytes are preserved. A verified browser conversion of that SolidWorks part is not available; the existing source STL remains available on demand. Open the native CAD file in compatible software to inspect and edit it.
