Pitts Biplane digital aircraft assembly. Biplane aircraft CAD design with two wing levels, interplane struts, rounded fuselage, tail surfaces, propeller, main gear fairings and a tail wheel.

PACKAGE CONTENTS
The ZIP contains the original native STEP assembly, a derived STL for display and an English source-file guide. All added filenames are in English. Original CAD bytes are unchanged. The derived STL is supplied separately as the web viewer.

GEOMETRY VERIFICATION
The native STEP was imported into local FreeCAD and its 99 nonempty shapes tessellated into 236638 triangles with 0.15 source-unit deflection. The resulting assembly was imported into Blender and visually inspected. The STL does not preserve native CAD hierarchy or editing semantics. Source units and real physical dimensions have not been independently confirmed.

PREPARATION AND USE
Suitable for digital display, CAD inspection and further model preparation. Check topology, wall thickness, watertightness, disconnected surfaces, supports, orientation, dimensions and component fit before fabrication. No verified printing profile, physical build, aerodynamic performance or working RC system is claimed. Hardware and electronics are not supplied.

ORIGINAL MESHOPIA PRESENTATION
The cover is an original local Blender render of the recovered assembly geometry, with new teal materials, studio camera, lighting and background. It shows a proposed finish rather than a photograph of a manufactured aircraft. Absent aircraft components were not invented.
