A polyhedral wing has two or more distinct dihedral angles along its span, meaning the wing bends upward in multiple segments rather than a single V-shape from the root. This geometry provides high roll stability and self-leveling characteristics. It is most commonly seen on free-flight models, high-altitude gliders, and certain unmanned aerial vehicles.

The new drone uses a polyhedral wing to keep it stable in crosswinds without needing constant active control inputs.
