With a sail made of tear-resistant spinnaker fabric and a frame made of fiberglass and carbon fiber, our Airgliders are significantly more stable than comparable wooden or foam airplanes. Their delicate rigging also makes the Airgliders a visual delight. The Airgliders allow for plenty of experimentation; for example, you can twist the wings to achieve a curved flight, and the center of gravity can be adjusted by adding or removing ballast. Airgliders fly best in calm conditions or with only a light breeze. - Wingspan: 40 cm - Length: 45 cm - Sail: Polyester - Rods: 3 mm Carbon fiber - Age: from 6 years - Launch: Hand launch, rubber catapult (included).
