[01] THE VALLEY CREASE (THE SPINE)
Fold paper strictly in half lengthwise. Run your thumbnail along the crease 3 times to create a razor-sharp keel. Crisp folds are the single biggest factor in long distance!
[02] 45° CORNER INSETS (THE NOSE)
Fold both top corners inward until the edges align cleanly with your center spine. Check symmetry: if one corner is even 1mm off, the plane will pull sideways.
[03] THE APEX LOCK (THE COUNTERWEIGHT)
Fold the pointed top nose backward into a diamond. This concentrates mass directly forward, balancing center of gravity so the aircraft glides flat instead of stalling.
[04] WING DIHEDRAL & ELEVATOR FINS
Fold wings parallel to the base keel. Always angle wings upward in a gentle 'V' shape (positive dihedral) for self-leveling aerodynamic stability in flight!
