A walkalong glider is a flying model aircraft made of paper, foam or a similarly light, low density material that is designed to be kept aloft by controllable slope soaring. The pilot generates the rising air by walking along with the glider as it flies with a paddle, often just simple piece of paper.
In the video below, the glider is made from Ultra Foam. Its density is only 4-6kg per cubic metre, while the air’s density is 1.25kg per cubic metre. This makes Ultra Foam glider extremely light in the air and and easy to control with your hands instead of a paddle! Ideal STEM project!
