Self launch ultra-light sailplane

Also have a look at this new high tech bird: http://www.ruppert-composite.ch/english/index.html
It.s categorized as a Class 2 hanglider but at 28:1 and a min sink of
87 fpm and a Vne of 81mph it'll outperform a Ka-6 on weak to regular
days and fly when nothing else stays up. They are thinking about
fitting an engine as well but you got other self launch options like
running off a hill, bungee self launch etc. thanks to an ingenious
design and a weight of only 100 lbs. Very interesting concept.
