Flew this at the xtremebigair.com kite expo on Sat, and it was great, very stable and good low end torque/pull. Notice the swept leading edge, cam battens on the leading edge also. Uses a bridal/pulley system same as the waroo, depower is almost as good. I was flying the thing in light wind and it felt great. Look forward to its release. They said there was still some tweaking to do before it comes out. I attached some photos.
