Selected older articles:

NPWC foilnose One part NPWC, one part foil. Only the nose of this NPWC is a foil, the rest is single skin.
NPWC v8 A NPWC version where the wing outline is described by a Cubic Bézier curve.
Sewing Machine Repair Solving a thread buildup problem.

Plans and updates for the NPWC can be found here or by clicking on the picture of the NPWC to the right. The NPWC is a sparless bridleless single skin soft kite similar to Francis Rogallo's NASA Parawing (NPW).
