May 2, 2004. Today we built the upper wing. Tess carefully inspects each piece as it goes in -- she doesn't want any surprises during flight testing!
* Dihedral: an upward tilt of the wings, giving them a shallow "V" shape. This shape makes the aircraft more stable in flight. The original Nieuport II, being a fighter, had very little dihedral to make it less stable and more maneuverable. Tess is hoping her plane will be so stable that it almost flies itself.
