Check out this new video of Windtunnel kite research with a Flysurfer Pulse2 at Delft University of Technology, The Netherlands.

Measuring shape and deformation of a Flysurfer Pulse2 surfkite in two different windtunnels using photogrammetry and laser scanning.
A collaboration of Delft University of Technology, Stuttgart University, German Dutch Windtunnels, Nikon Europe, Flysurfer Kiteboarding and Max Derata Photography.

Conclusion after $1M in testing - it still looks like a pillow!

Flysurfer added another $300 to their price to cover the cost of "Gadget Geeks"

Suggestion:
Why don't you test it with waves (swells) to see if it will come out of the water after that?

Yeh I want to see how you relaunch a Flysurfer kite after a 4 foot wave has gone over the top of it.

Well Marty maybe you should try it ... I think you'd be very surprised.

I've never had any problems with relaunching a Flysurfer in waves ... last two times I flew LEI in waves not only could I not relaunch but both times the kites were ripped in half!

No worries Ian, would love to test it, where can I get my hands on one on the Goldy? maybe you can send one to the boys at Surf Fx and we can film it and post the findings on here!
As to "last two times I flew LEI in waves not only could I not relaunch but both times the kites were ripped in half!" I dont know what your doing wrong or what kites your were using but if that was the case for all of us kitesurfing would have to be one of the most expensive sports ever!!! lol

Marty give Jeff Roberts a call on 0418 880 509 and he should be able to arrange a test flight for you - else email ianyoung@iinet.net.au and I can put you in touch with other guys who fly Flysurfer on Goldie/ North NSW Coast who are happy to let you fly their kites if you know what you're doing (... which I'm sure you do ;-) and prepared to listen to some basic instruction on how to get the best out of a Flysurfer kite

There seems to be a lot of misconceptions about foils; your point above was the first question I asked Ian when I met him to try a Flysurfer. He said they can stay on the water for considerable periods of time, including having waves over them and still be relaunched. Conditions were light on the day to the point where I ended up having the kite in the water for at least 15 minutes while it was too light to relaunch (lack of skill/very light wind) and at no time was I worried it would sink as it maintained an excellent volume of air. Similarly self rescue is just as easy as on a LEI - perhaps easier.

FWIW, I currently own a Psycho IV and Cult 09 so have experience on both, and I feel no less safe on the foil. Like many things in life, you can follow the crowd and go on what other people tell you, or you can test things for yourself and make an educated decision. If you have questions then ask someone who flys one or make a time with Ian to try one.

Cheers,

Ben.
