The Monarch is not a foot-launchable rigid wing hang glider, but it is a tailless ultralight sailplane that can be made from plans. It is designed for fun flying rather than all-out performance.
You can find more information on the Monarch here and at the Bailets Composites site. Also, Philippe Aeberli is building a Monarch in Switzerland. You can find information at this page ; look for the Monarch link.
You can find more Marske Monarch information at Continuo.
