+# Fixed Wings for Fab Labs
+
+
+Fixed wings requires reflex airfoils at least in the root to be stable on flight. Taper angle is highly recommended as they provide:
+  - Largest area to play with the components and control the center of mass.
+  - Nice stability (yaw)
+  - Larger moment in the tip of the flap
+
+We can manufacture the wing as unrolling its (almost) single curvature surface. This makes it a great candidate to be manufactured in a 2.5 axis machine (likely with a knife as we will need to crease our flat preform. The optimal crease is a V cut operation as the Zund provides).
+
+## Design
+
+Free tools are available to let us estimate range and endurance, design it while analyze it(XFLR5) and design it (MACHUP).
+
+As an example, I am starting to design a fixed wing for Bhutan. I used XFLR5 and Rhino.
