Crusader Swing Wing blunt cockpit nose — Revision B — ESTIMATED
Source identity: HIST_KIT1961_CRUSADER

This free pack preserves the original STL and STEP geometry from the expanded
Estes Nose Cone Library B. All geometry is in millimeters.

Base diameter: 41.58 mm
Exposed height including features: 89.00 mm (excludes shoulder)
Shoulder: 40.51 mm diameter x 18.71 mm long
Overall X x Y x Z: 41.58 x 45.32 x 107.71 mm
Evidence confidence: low. This is not a numerical tolerance.

These models use educated estimates, including inferred dimensions and shapes.
They are solid exterior references for CAD editing, not verified replicas or
finished hollow flight parts. No printer clearance, original hollow interiors,
electronics or recovery hardware are included. Solid CAD does not prescribe
100% slicer infill. Digital geometry checks do not validate physical fit, mass,
strength or flight suitability. Check actual tubes and print fit yourself.

Why this shape was chosen:
Crusader photo shows a relatively short rounded cockpit nose, unlike long needle types. Estimate elliptical external form plus cockpit bulge. Kit facecard/instruction images were visually inspected; proportions are estimated, not measured from a calibrated drawing.

Estimated fields:
- profile.stations_mm
- shoulder_diameter_mm
- shoulder_length_mm
- features
