I'm Excited, for where this wing, could take kite technology , in
the next few years ; got a feeling that they might look a bit different
soon !!!

I dont think the GF battens function is to stiffen the leading edge, there I tjink they ll still use the nylon reinforcement. The battens shoul be used for stiffening the top of the canopy.Schietwedder wrote: ↑Thu Jun 25, 2020 6:02 pmI don't understand how much discussion there is about the battens.
I'm quite sure the Benni and the flysurfer guys are quite happy with the glassfiber battens and there isn't much to be improved for now especially on the material side, its way more important how to use them.
They are economical and for their good mechanical properties light enough.
I used the same or similar gf rods in my diy kites as it was the only thing i could find which would have more spring capability and tension than the grass cutter nylon and which would bend enough for the nose radius. Even now when using the thinnest batten available to me (0.8mm) I can't bend them around the 10 tip cells for a 12m freeride size.
I'm quite sure that the race kites have thinner and shorter profiles (high AR) which ask for even more flexibility than 0.8mm maybe 0.4mm in the tips or use a different material (nylon) in the LE.
If you wanted to use carbon or a combination of composite materials you would need rods of 0.2mm or thinner for the same flex whicj is quite pointless from an economic point not even considering if they are made in that sizes and how easy (UD) they break.
Also I'm not sure wether they use the battens for maintaining the profile shape.
With sufficent internal pressure that should be the job of the ribs which they are quite good at usually.
I would think the battens are more for distributing loads of thebridle points (point loads) onto the ribs and internal structure. Therefore you might want a soft transition so not a super hard batten.
The way they are s- shaped could induce some reflex or other deformation of the canopy when depowered which wouldn't be possible with a 2 point mixer.
My guess, it's a totally new technique in kites at least...so the only ones that know is the designers and maybe some riders who have ridden it and understand what the differences are compared to 3 row and 4 row designs.
There has been a lot more development and research in PG design where I think some of these new ideas come from (Skywalk)

I would be slightly worried if my name was rob whitall to keep up.
A lot of new or never practically used ideas which seem to work out really well. Also the 13m VMG with AR of 13 they released as a proto last year.... Hats of to even make such a thing fly...
They have got a lot of things right and understood which is harder then you think in kite design.
The interesting part is these kites are locked in now for 4 years. If the Flysurfer is the fastest, they'll have a monopoly for 4 years! (at least for IKA events and Olympics)
My guess is if you have so many # you just copy and paste.joriws wrote: ↑Fri Aug 28, 2020 6:07 amHashtag only says VMG but is this VMG2? Nevertheless awesome jump captured on video.
*edit* Coloring and 3 stripes is Sonic3 11m (or 9m). On my first check was checking on small mobile screen and did not pay attention to kite details, why team rider tagged VMG?
