test of Hysper v2 from Sky Country, relaunchable single skin

[Smeagle]

In your opinion, which is the one you can keep in the air with le lightest wind at zenith ? And by looping it ?

Was out again yesterday and did compare this aspect to Peak5 of a friend.

"Keep in the air" in active flight style: the Hypser wins. But not by much. It's advantage is, it can hold shape a little longer in very low wind and will turn faster

But "keep in the air at zenith" (passive): The Peak5 (and Peak4) wins... If you let the Hysper rise to Zenith it will rise and rise until it is "Over the edge" and then it will slowly sink down until it looses line tension. It will NOT collapse, which is very good. Problem: It does not flap when depowered. The Peak5 (and from memory Peak4 too) will start to flap a little, which keeps it from reaching the edge and it can "autopark" at (or near) zenith.

But this "not flapping" is an advantage for riding... The Hysper has a longer range of usable depower because of that! I can use the full range of depower on my bar for riding! Peak4 started to flap and collaps (in high wind) at ~1/2 way of depower! I have not tested the Hypser in high range, yet, but I THINK it should give big advantage in those conditions.

I really prefer the Hysper to the Peak. I was riding with my friend in very mixed conditions (but not in high end), and none of the kites will really "ride" earlier or faster... BUT Handling of Hysper is more fun. It's more direct, turns faster/harder and develops more power from movement. And my friend is ~30kg less weight and bigger wheels, so 1qm more is no "unfair advantage" I guess I feel Hysper will also go upwind better, but I will have to test on water with TT to be sure...

I did a lot of videos yesterday in 0...8 knots... Will take some time to sort that, but I intent to make a "Hysper 14 vs. Peak5 13" video in both "riding" and low end (keeping in the air) conditions. We were riding in parallel, I often followed her to compare performance - I hope I can do some snippets were both are visible at the same time...

Excellent review, thanks.

During riding i suspect hysper has a better perforlance by looking at slightly higher aspect ratio.

About stability when line tension is lost, this is another advantage of closed leading edge (on top of water relaunch): years ago with my peaks in very light wind in mountains, it was a real problem that required to go to the kite once collapsed to prepare it propeely on the snow for relauch. In punctual 0 wind lull, hysper (or flysurfer peak hybrid now , certainly) is more easy to manage.

On my ex hysper2 14m , it could stay at zenith almost to its ultimate wind and keep line tension like you seem to say on the peak. But it is "old" souvenir, and perhaps improved by my ultralight cloth (27gr).

Wear rate will also be interesting, and laybe in favor of Flysurfer in view of the winder experience ?

Nice review again thanks.

"Nominal" the AR is the same as Peak4, 4.

But your are right, is has a little higher AR: I put the Peak4 13m on top of the Hysper 14m and I see, Hysper has a little more span, but main difference is the tips are more rectangular, not swept back. Not sure what this changes? But AR is span in relation to medium "length", so could work out to the same AR? I think, this shape turns better while still giving good performance.

I did not compare to shape of Peak5.

Yeah, I too think it's the weight. It goes to zenith but it starts to sink, it cannot keep up in low wind. It's only in very low wind, if there is a little more, it will be pushed back by wind a little deeper in window an than it can keep up.

Wear rate will also be interesting, and laybe in favor of Flysurfer in view of the winder experience ?

The Peak4's material feels a lot thinner. It's strange, as it is not really lighter. But really, the Hysper in normal cloth feels more solid bust still is a little less weight than Peak4 13m while being 1m more. Only difference in construction that could explain this: The Peak4 has "rigid nylon lines" in all cells, the Hysper only has them on the cells were bridles are connected. I think this is a good decision, it does not need more, as the filled front give enough stability.

I really don't think the Hysper will have more wear than Peak4. And a lot better than Peak5: On Peak5 the fron parts, diagonals/band are thinned out very much, too much for my liking. I know, most damage on Peak4 was in those parts. I did not see any wear on the very thin back part of Peak4s. The the back part is stronger on Peak5 - which was unneeded IMO - but the front part is not as strong, which is baaad. When buying my Peak4 I looked at a lot of used Peak4, and several of them had bad visible wear on the white front parts, diagonals and line connectors...

Hi everyone

Two questions
a) does sky country produce again? (Please only answer if you know, I know the war is going on, but other ukrainian producers (eg karat) resumed production.
b)I'm looking for a low wind option, to be used with a big foil from 5-6 knots on water. Might the hysper 2 in 14m be an option? or better 11m? Does it hold in the air static on ground in 4knots (that's about what I needs to be +/- stable in 6 knots on water.

[Smeagle]

a) Yes, sure, I just bought one a few days ago. I just sent an E-Mail and asked politely, if they want to sell or have other priorities right now. They wanted to sell.

b) The 11m might be enough in 5..6 knots, the power of the 14m is insane. In "gusts" of 6..7 knots it already pulls a lot. But I have not tested the 11m. At real 3..4 knots, meassured at ~2,5m hight (holding wind meter over my head) it flights stable. Still it needs more input than a Peak, it will not "autopark" like the Peak will do, you have to control the position by powering up a little, or it will fly out of the window and fall down. But it won't collapse, so at ~4knots it should stay up anyway? In my tests I was always in the range 1..3 knots OR >6 knots, so hard to tell, yet As soon as you are up and going you will keep going in 2 knots of real wind, so it is only a problem of starting and keeping in the air when static.

Yes, Sky Country have production now

I just ordered my 2nd Hysper Up to 2..3 months it will take I hope, it will be faster...

I fly the Hysper 14m with 20m line, seems to be perfect. I want to prepare a bar for the Hysper 8m I orderd, what do you think is good length for the 8m?

I want to use it with Hydrofoil mainly. Low end, but not "extreme" low end I guess range 7...12 knots. Not sure, if I will be using it in higher wind too, what do you think, would it work?

I use a 65cm bar for Hysper 14m - I had this from the Peak 13m I used before, but it is not really needed for Hysper 14m. I tried it on a 52cm Bar and it was still fine.

So I guess, 50cm bar should be enough for Hysper 8m, or what do you think? Is 55cm better? I Want to make a ultra-light bar (carbon) and want to order it now so I can build the bar in time... Bar is custom build, so it takes some time, too...

Thanks,

50 should work fine. I built a carbon 55cm for my 8m. Seems maybe a bit longer than I need. It is a very agile kite indeed.

[Smeagle]

Thanks!

It is a very agile kite indeed.

Yeah, I am really surprised how agile the 14m is! A lot faster than the Peak 13m, did not expect that but am very happy about that

So I guess, the 8m will also be more agile than the Peak4 in 8m, which I know well? Will be a lot of fun!

From the experience with Hysper 14m I expect, the 8m Hysper should cover the wind range of Peak4 6m and Peak4 8m... At least I can go in much higher wind with Hysper 14m than I could with Peak4 13m... Peak4 starts to behave badly in higher wind, Hysper does not do that so far. So I skipped the 11m, I think it would be too close. After I get the 8m I will decide if I need an 6m or 4m as next size. But I plan to get a full range, really love that kite.

What line length did you use for the 8m?
