"A slightly altered version of the Relax, a kite
described in Shimmelpfennigs book
"Phantatishes Drachenwelt", and one of the
first kites with skincurving. The name
says it all, it is a very relaxing kite to fly.
Very good tracking, and an even pull
all over the wind window. I even use it
for powerkiting in stormy weather."
