Re: Foil Kite tuning tips

You can adjust profile and flying characteristics by opening and closing an internal zipper that affects internal inflation pressure. That is true. To have it as strongly evident as it was in Psycho4 there are many things involved. At very low AoA (when fully depowered) stagnation point moves (part...

No, I'm starting to having enough of these BS corrections. I don't know why it should be me.

Re: Foil Kite folding in half when going upwind!?

As to kitexpert, he is a bit of a strange one. All evidence points to him being a Tube kite designer, you just need to talk to some, read their posts or see that new BS article. He doesn't seem to actually use foil kites much. Which is more strange because he gives lots of advice on them, and incor...

Re: Flysurfer hard/soft steering line question

It changes the ratio of the mixer at the point it engages. Ratio increases from 421 to 620 (or 310) to pull Z more. Results in camber increase with more lift and worse L/D. More bar pressure because of mainly A is supported by mixer at 1/4 to bar but also more tension on Z. You also get better rela...

Re: bridle line types: Ozone -Flysurfer

Unsheated: thinner, loops can be spliced, less drag, less durable against abrasion Sheated: thicker, loops must be sewed, more drag, more durable Race kites have thin unsheated lines for as low drag as possible. Freeride kites like HL compromise lowest possible drag to better handling and durability.

Re: Foil Kite tuning tips

can you explain how camber of profile is changed when aoa is changed lineally? Yes, I've already done it several times. When kite is designed line row locations and mixer pulley ratios are chosen for desired effect. Camber can be unaffected, it can be increased or in some weird tweakings even decre...

Re: Foil Kite tuning tips

Points 2 and 3 are the same, you struggle with english don't you. :lol: No. This confirms my doubts you foilholio still don't understand this kind of things. we all now know you think you know more than Mr Armin Harich. I don't care who it is, if it is not correctly explained I correct it. You foil...

Re: Foil Kite tuning tips

Actually Armin's video is a bit misleading. He claims kite increases camber when its AoA is increased, even though his drawing suggests that is not happening. And when decreasing AoA camber is claimed to decrease for bigger positive momentum, again picture does not prove it (Armin draws a low camber...

Re: Foil Kite folding in half when going upwind!?

Just extend Z more like foilholio says :D It is The Fix and it has "same effect" than adjusting A-B :lol: Brakes are still perhaps a bit too tight, aren't them, foilholio? :lol: "Same effect" :lol: Serious advice to Nash556: Don't follow foolish advice you can get here. Then you can save your time a...

Re: Foil Kite folding in half when going upwind!?

You could level them and lengthen Z 6cm to get the same effect,... No. Lenghtening Z can't affect A - BC relation. If you want to adjust A-B relation you must do it between A and B. If you take Z completely away A-B-C are still pulled like before and also presets they had (mixer adjustment position...
