is no one going to talk about the presentation of the kite.

Mine arrived yesterday

Contents, repair kit, kite strap (for packing) it's a nice padded strap with a buckle and clip and a new ballast bag which is a durable dry bag which you can store stuff in to keep dry or fill with wet sand and be sure that it won't leak in the car on the way home.

Also, 2 bags! the main outer bag which is a really nice rucksack and an inner bag which you see in the vid above that Armin has next to his lounger.

Overall this is the nicest presentation of a Flysurfer kite I've ever seen. Really great job! it does feel like a premium product.

Great video Armin!

Line lengths are always a conundrum!

Toby needs a Sonic!

Ok, now I can see the construction of kite. 55 cells, AR 6.6 to 7.2, 7 air intakes with four cells in between, bridle spaced 2-3, full cell D-ribs, miniribs, lot of straps...

To have that kind of bridle spacing means there is "excessive" D-ribs, but more the better I guess :) Inner parts seem to be optimized for lightest possible weight though.

In general basic parameters: AR, cell count, bridle spacing/bridle levels, air intakes/spacing/relation to inner parts looks well designed but who would except anything else from the leading foil kite brand. Line row locations by the chord and mixer (pulley ratios) are usual - and why shouldn't they because it is logical and works very well. So third part (or second, IDK the order) of late "Triple Depower" is not strong (if it is there at all) and I doubt if there is second (third) of the three either. Looks like "just" a depowerable kite.

Different kite sizes have different AR's but same cell count. Apparently here thought has been 55 cells is enough for biggest sizes/AR's and more than enough for smaller sizes. For sure it is, but it leaves a tiny cutting corners design feel. Question is: do the smallest sizes really need that high cell count or would slightly lower cell count with simpler/lighter weight construction be even better?

Kite shape has clear relationship to Soul, it looks like Sonic3 is like a high AR version of Soul. But of course there is not so much room for different shapes if kite has that high AR. Canopy curve looks nice. Airfoil is apparently quite thick for good lift and better usability for intended use, thicker wing is also structurally better.

This shows A line row construction and how D-Ribs apparently are designed. I'm not so excited either of them but of course it is one way to do it. I guess motivation here has been to have those 7 air intakes located like they are now. No doubt it is good work in that respect, they are many and well located.

Per my view the 55 cells are definitely needed and it is good optimazitaion between weight and performance. If you consider that paragliders of AR 5.4-5.6 has generaly 59 cells, and paragliders with AR. 6.6-7-0 has 70-80 cells you can really see that 55 cell for 9.0 and 11M Sonic with AR 6.6 and 6.8 is really just the basic minimum. In paragliding design they try to maximize performance for the given aspect ratio. Just to get the understanding that how much perfomance gain can be gotten by raising the cell number just consider that Nova has a high perforamance intermediate paraglider with AR 5.19 and 99 cells called the Nova Phantom. Most successfull competition paraglider(Ozone Enzo 3) has 101 cells for AR 7.55. So this makes the 55 cells a very well balanced compromise.

Today I used my 18er Sonic3 in Workum the first time.
10-12 knots and 17/18er gusts. My weight 75kg. 133x42 Zero-G Board.
I jumped a lot to get used to the timing, did some highspeed tests and tried to collapse the tips (like in the videos above) by driving towards the Kite and in parallel depower the bar... but it didn’t work!!
No idea what they did in the videos above...
The only thing I could Imagine is that this was prototypes!

Yes, they all used the last generaton of prototypes named X9 and the feedback flow into the serial Sonic 3.
