Plans for this glider are at: https://www.apogeerockets.com/Advanced_Construction_Videos/Rocketry_Video_59 Part 6 of 7. This video shows the construction sequence for making a Rogallo wing glider that is boosted into the sky by a model rocket. They are often called flexie gliders because the wing is flexible and can be rolled up and stored in a small space. In model rocketry, they are used in the National Association of Rocketry's flexie contest.
