Check dihedral and washout

Steps

1. On the Bench screen, choose the aircraft, then tap Dihedral.
2. At the top, choose Dihedral or Washout.
3. For dihedral, lay the iPhone across the left panel, top toward the left wingtip, and tap Capture.
4. Lay it across the right panel, top toward the right wingtip, and tap Capture.
5. For washout, lay the iPhone front to back at the root, top toward the leading edge. Tap Capture, then do the same at the tip.
6. Check the result, then tap the Save button to store it with the wing.

Good to know

• The model doesn't need to sit level. Its bank cancels out of the total.
• Capture the center section too, to see the left and right sides separately.
• Measure or type in the wing first. Dihedral and washout are saved with it.

Words used here

Dihedral

The upward angle of each wing panel. It helps the model level its wings by itself.

Washout

A twist that sets the wingtip's leading edge lower than the root's. It helps the root stall before the tip. The opposite twist is wash-in.

Root

The inner end of a wing or stab, where it meets the fuselage.

Tip

The outer end of a wing or stab.

Leading edge

The front edge of a wing, stab or control surface.
