Customizing a Wing’s Pieces (for Incidence, Size and Position)
In the Element Specs box—the same box used for applying control surfaces to wing pieces—is
the piece incidence setting, highlighted in blue in Figure 3.21. This sets the upward angling (or
incidence) of each piece, in degrees. This allows you to warp a wing section to point up or down.
Using the checkbox labeled ”customize chords,” you can change the width of the wing section
from its leading edge to its trailing edge (that is, its chord length) for each piece. Pieces are modified
just like when adding a control surface to a piece; the boxes on the far left correspond to the portion
of the wing section that is closest to the fuselage, while the boxes on the far right correspond to
the portions farthest from the fuselage.
Figure 3.25: Customizing an aircraft’s chord size and position
Normally, Plane Maker calculates the chord length of each piece (again, the distance from its
leading to its trailing edge) by interpolating between the root chord and the tip chord, which you
set in this tab’s Foil Specs box. Using the “chord ratio” setting, though, you can modify the width
