 Although many walkalong gliders are flying wing designs (as are almost all flying and gliding animals) walkalong glider designs based on traditional fixed-wing aircraft (incorporating an empennage or tail) have been made from balsa wood sticks and tissue paper.The paddle should be made from a sheet of light weight but rigid material such as corrugated cardboard or foamcore.The larger the area of the sheet the stronger the updraft created at the top edge.
