Wing Construction

The Pou du Ciel employs biplane wing with much stagger and not much height difference. There is no horizontal stabilising tail-like surface and no elevator.

To make the lower and rearward wing, I used a profiled foam blank.   The blank is a bit shorter than the required span, so I added 1/16" balsa wingtips.

Foam blank with balsa tips, port side is snipped to approximate shape.

Foam blank to the correct chord and planform shape.

Sand to airfoil.

Polyhedral to simulate the curved wing.

 

Remaining to do:

• anchoring system for the flying wires;
• more chord lines? perhaps;
• covering and finishing.
