One candidate is the Zagi THL, that is Thermal Hand Launch, which naturally will thermal, as the name implies, even if it takes its time to get there (that is, it aint a speed demon)! Equip it with a hook and you'll have lots of fun chasing thermals! For a night-time hand launch of my THL see <URL:http://www.ozemail.com.au/~majali/Zagi-THL.jpg> For hook design see <URL:http://home.beseen.com/hobbies/jebbushell/tord/tord.htm> There are lots of other model flying wings that are designed for thermal use, especially in Germany! Full-size thermalling flying wings can be found in the US and France, for instance :-)!
