You can only increase pressure by sealing the kite more or positioning inlets better. The simplest mods to improve Pyscho4 are FLS, remove zip, remove over pressure valves, remove WAC( if not used). The bridles could probably be altered a bit, for example maybe flattening Z.
No the Psycho4 has a fifth line/FDS, change that to FLS and remove the fifth line and bridles.Skywalker7 wrote:Do you mean to remove the FLS line as well?
Yep, I think the pulse2 started with this. The pyscho 4 has a valve in the middle that if you open the velcro inside increases the pressure.Skywalker7 wrote: Per my knowledge the earlier kites Psycho 4 and Speed 3's had a design that when you started to depower the kite the angle of the intake valves changed a bit and the internal pressure of the kite started to decrease in order the leading edge starts deforming and this made a the kite to stop overflying through the wind window.
If it holds pressure well it will be more stable, other wise they would have just used a thicker airfoil or more reflex.Skywalker7 wrote: . Now what I feel with the Soul that the internal pressure is always on the maximum and the designers found a different way of making the kite stable(doesn't overfly) so the kite is able to fly with the max possible internal pressure.
Basically all foils drift back near perfectly at 12. If the soul can drift in the side of the window with full slack lines like some inflatables then that is impressive.Skywalker7 wrote: The 10M Soul in 20-25 knots is so "pumped" that actually when it should collapse with totaly loose lines it drifts back and up in one piece just as LEI kite untill the bar lines gets straight.
Not the only. The air pressure is a function air forced in minus air lost out plus a factor of distribution loses. I can certainly see them improving them all. It is possible the air intake positions have moved only slightly or their sizes have changed, or the airfoil has changed.kitexpert wrote: Only possibility for Soul to have higher pressure than earlier kites is if it is able to store max pressure which is reached during fastest part of the flight. Air intakes, valves and locations have not changed.
Apparently Soul is more airtight. Some fine adjustments have been made but nothing that essential. Doubling inside air pressure is pure fantasy.foilholio wrote: I can certainly see them improving them all.

Perhaps so. In fact there was known deformations in LE because when depowered stagnation point moved above air intakes and inflation was compromised. FS explained this flaw "helping stability at low AoA" or smth BS and many believed it (For sure it helped stability, like adding 1kg sand to TE of the kite - no overflying any more ) Now foil kites have LE stiffeners and doubled air intakes or variably located air intakes to keep LE as clean as possible all the time - no one wants or needs such flaws "for stability" any more.foilholio wrote:Yep, I think the pulse2 started with this.
