While most outsiders considered the Ewoks a primitive species, the short stocky humanoids had learned to use their natural resources to manufacture a wide range of incredible tools.
Among their many inventions were catapults, numerous handheld weapons, expansive tree villages, and a variety of traps. Their most stunning creation, however, was undoubtedly the versatile hang glider.

Characteristics

An Ewok would begin constructing a hang glider by stalking and killing a number of large animals. These creatures were skinned and their pelts stretched and dried until they formed a durable leather. The skins were then sewn together and connected to a simple skeletal framework which was made of a special strong, light wood.

History

Originally, the hang gliders may have been used simply to transport Ewoks across the forests. Eventually, they began carrying rocks, spears, and slings for use in hunting small creatures from above. The Ewoks soon realized that these same weapons could also be used in defense against towering monsters such as the Gorax. Furthermore, with the Wisties guiding the Ewoks around dangerous convection currents, the Ewoks were also able to use the gliders as a forest fire suppression method by airdropping Master Logray's magic foam.
Thus, when the Ewoks agreed to aid the Rebels, they used their extensive experience with their remarkable hang gliders to gain an advantage over the land-bound stormtroopers.
During the battle, the Ewoks also attempted, unsuccessfully, to use their gliders against All Terrain Scout Transports.
