From the one I have it has no de-power just the four lines and like an NPW no brake tension results in some flapping and yes less power but I wouldn't say that's a de-power kite, hence the "Z" bridle making a difference and makes it "easier" to fly and does not seem to compromise the window.

I do use my de-power kites on handles, but there is a trade off doing this, as you power-up you get more power transmitted down the brake lines as that is what is controlling the AoA, just something I've got used to. Once on a turbo bar tho all is really sweet.

So fixed bridle kites on handles just became depower kites? what the eff?

In that case I got a ozone haka 5m depower kite for sale. I mean, it was FB on handles with brakes and zero depower yesterday, but then I read this thread, and everything must have magically changed.

:D Only when the lines at the other end of the handles have some pulley magic going on, otherwise it just aint de-power.

So adding a single pulley to a FB kite on handles makes it a depower kite? I honestly don't agree.

I would LOVE IT if we could talk about the FLYSURFER PEAK in this thread, and perhaps you guys could have a PL whatever-it's-called thread as well, so we could kind of be on topic? I know I kind of got roped into the off-topic discussion, but I don't think it's helping people learn about the PEAK.

Agreed ;-) (needs more than just one pulley, but that's another story).
Back on topic,

Still interesting how the two companies have attacked the single skin design from completely different angles, I do like the PL approach of a much more simplistic looking kite, even though no kite is a simplistic thing, the trick is getting it to do the job in the most efficient manor.

How does the Z-bridal set up effect the AoA as compared w/ standard set up on NPW, Skin or other similar kite?


I have a FB w/handle racing style kite with a pulley a z-like set up between brake and power LEAD lines.



How is this set up affect Kite? I was only told it helps turn the kite faster and or make it more responsive...especially w bigger kites.


Seems when using brake it may keep AoA lower...more constant ......but I'm not sure? I defer to others

I agree that we have got off topic badly, got a couple of single skin nuts interested here I think! Sorry to the OP. Back to the Peak.

So the Peak appears to be a true depower single skin while the Skin is not. You can find the bridle plan on this page: http://flysurfer.com/produkte/kites/peak/
It appears that pulling the bar tilts the A/B/C bridles back and forth relative to the brake bridle and changes AoA.

What they haven't done is figured out how to stop the luffing that occurs on the wingtips in a setup like this. I remember someone posted a NPW with a single pulley depower on an old thread of mine: http://www.powerkiteforum.com/viewthread.php?tid=22137#pid21...
Notice the wingtips doing the same thing when AoA is changed.

Perhaps a system with more pulleys would do better - or maybe the luffing is just cosmetic? Personally, I just don't like luffing in a kite from an aesthetic point of view.

Off topic for skimtwashington: Z bridles do not affect the AoA, which is determined in the main bridles. Your setup is not technically a Z-bridle, Z-bridles are on the kite end of the lines and all they do is apply a constant brake bias regardless of line sag or slack on the brakes. Allowing you to fly a kite that requires constant brake pressure without having to apply that pressure, well, constantly. Your setup allows you to apply greater force to the brake lines via the "leverage" of the pulley, making it easier to pull in the brake on bigger kites.

I don't like luffing either! It's for that reason when I change the AoA on mine it only applies to the centre panel, this approach keeps the wings fully inflated with no luffing, I may not get a full de-power range but I get stability right across the wing on low AoA.

So the question is who has flown a Peak? It has a hefty price tag is it worth it?

Neat how he has picked up the Z bridle from the NPW flying community. It really does help with flyability

Why didn't I read the Nov article I'm mentioned in it :D
