Re: Peak4 vs Shaman2

"Future of kiteboarding, a single skin kite that can float"

:) Think we already have that kind of kites, they are often called LEI's.

Re: North Prototype

That's not what I was trying to say. Of course he knows how a kite is designed just from his memory and for sure he can design a kite that flies just from his memory.....but designing a kite that has been fine tuned for 12-13 years just from his memory.... I doubt that. Ok, but I'm afraid this "fin...

Re: North Prototype

It's very unlikely that he could bring his files from the design software with him as that would be stealing the intellectual property of Cabrinha. This mean that he should have to start more or less from scratch or designing from his memory which should be pretty hard as I'm guessing that kite des...

Re: Flysurfer Peak 4

Use of flaping as aerodynamic brake is part of peaks charm. It wont be peak without flapping. This flapping is not property of Peaks only but all single skin kites which are depowerable. They all flap when depowered because there is no such support in their structure to prevent it. Only higher AoA'...

Re: First foilkite

If it is 40 sessions in snowkite, it is already a lot :?: If it is 400 sessions it is lot. I have 40 sessions in few months, easily within normal snow kite season. But Hyperlink goes better upwind in spite of lower aspect because you can push the depowered kite further into the wind. That is very h...

Re: First foilkite

He says he’s flown it about 40 times. If that is true that sounds good. bad problems with ageist. Under 10 knots, deluxe is a must, but the thinner fabric becomes porous sooner. It really depends on how used the kite is. This. If fabric is porous it is serious problem. Not only fabric is problem bu...

Re: Foil Kite tuning tips

There's a bit too much calculation in haare's video. His english is pretty good though. Best fix is to restore everything back to original lengths. Working order is: 1)flying lines 2)pulley lines/mixer 3)longest bridle lines 4)rest of the bridle lines. Because practically everything which changes in...

Re: Concept'air 12m Pulsion kite

Low weight does not make kite any bigger or make it pull more. For design point of view making kite from lighter material is trivial, 10 knots is force 3. 6 knots is force 2. I start to consider flying tube kites at 12 knots. I can go lower but is less fun. Yes a kite that pulls harder can lift in ...

Re: Concept'air 12m Pulsion kite

No doubt a kite that weighs less helps quite a lot. Low weight does not make kite any bigger or make it pull more. For design point of view making kite from lighter material is trivial, no amount of CAD can help that. If 12m kite weights 132g more or less isn't very interesting. But when FS makes v...

Re: Kitech FRS

Is that Minima Beta? What explains the resistance to collapse? No, like Stef already wrote. Main explanation for collapse resistance is stable airfoil. If airfoil is high lift high camber airfoil it is not stable. AR of the wing is also very critical, it is much more difficult if not impossible to ...
