Paper Airplane Project

Which paper airplane will fly the farthest? I am doing a science project that involves making paper airplanes and measuring their flying distance. For my research, I have looked in a book called "150 Science Experiments" by Barbara Taylor. Online, I have visited: http://www.paperairplanes.co.uk/planes.php,
