Flysurfer Psycho 4 adaptive Canopy Shape

Postby FredBGG » Tue Jul 08, 2008 6:25 am

Well I have heard that the Psycho 4 is being presented to dealers this week and will be shipping in a couple of weeks.

This kite brings a whole new thing to kiting...

Adaptive Canopy Shape.
Basiclly the kite will go from a C-shape to a super flat shape on the fly while sheeting in and out as well as trimming with the depower strap.

Fully powered up, a PSYCHO4 10m has 8.5 sqm projected area, fully depowered it has 6.7 sqm
The camber of the kite also changes. The camber is the curve from leading edge to trailing edge.

Basicly variable projected aspect ratio.

Here are a couple of photos showing the kite more powered up and less powered up:

What is more intresting is that to turn the kite will basicly spread one wing tip while pulling in the other wing tip

Here is an image of the kite just before a turn:

Aparently it is the fastest turning foil made. This is most likely becasue it relies on variable projected aspect ratio and variable camber rather than angle of attach for power.

I have heard that only the bigger sizes will be coming out first, because they are still working on slowing down the smaller sizes because they are too fast :o

Here is a pic of two kites flying side by side one more powered up than the other.

First videos should be showing up next week some time.

This is all from info found on the web..... I have not flown one yet, but can't wait.
Official launch should be soon too.... along with more accurate information.

Anyway a projected aspect ratio of 85% sounds like a load of power to me 8)

One other thing... the central vent can be closed or left open.
This changes the internal pressure of the kite and it's power and behavior.
Open for a more agressive kite... closed for a more gentle kite...well as gentle a a Psycho can be :wink:

Cheers

Fred

I am looking forward to some video footage of this kite and how it performs. I have been reading snippets of info for months...it certainly sounds promising...

Glad to see someone is pushing the envelope with innovative thinking in foils

I am really curious to see how this kite preforms in the waves.
More C-shape when depowered riding down the line.
We all know that the Arcs and C-kite are great down the line.
Flat and higher projected aspect ratio for getting back upwind in the light stuff.

I am hoping that the Psycho 4 15m combined with a Spleene Zone 08 could be the magic
low wind wave riding combination.

Hello Guy
i allready fly the Kites (2 weeks ago) with armin and we test some different trimms
yes the system works and the ps4 is fast very exteremly fast !
I have heard that only the bigger sizes will be coming out first, because they are still working on slowing down the smaller sizes because they are too fast
yes thats true 12 and 15 are ready (i have send the firt kite to my costumers)

and the 10 8 and 6 will take some days longer because the are "to" fast...

i (106KG) have a new love the ps4 15 very fast (normaly i fly silver arrow and sp215) wonderful depower ...

The magic is for real. P4 15 review.

Now I'm just waiting for PMU's reviews to confirm all the above,
like finally Foil kite designs succededing and becoming superior to inflatos. :lol:
It might take many years R&D how to apply the copy of Adaptive Canopy Shape for the rigid inflatos,
like now the well excepted Bridals from the past on Bows and Hybrids.

Out of interest sake, how does the depower on these kites compare to a bow kite?

They have a very wide range. The depower is at least as good as a bow kite.
I have not done direct comparisons, but I fly with friends who fly bows and we have the same range. While having the same top end at times I will have a bottom end advantage.
Generally I will be flying the same size as other riders despite weighing 30 to 40 lbs more.

One area where the Pulse 2s have an advantage is self launch in high winds.
Before launching the kite lies flat on it's back and there is less risk of something going wrong.
Assisted launching is totally un neccessary with a full bridled foil.

Cheers

Fred

Yep, it can be a fundamental design advantage not being bound to a rigid canopy, and it looks like they've done a nice job of leveraging that. The PL Scorpion also very noticeably flattens-out when you quickly pull-in the bar (part of the reason for it's nearly absurd ability to shoot you to the moon jumping), but the mechanism behind this behavior is obviously completely different (somehow lift at the tips is dramatically increased vs. the center of the kite) since their is no bridle or other direct LE support on an Arc. Two ways to take advantage of the twinskin foundation to have an adaptive canopy shape.

For high winds I don't think any of this is necessary (hey, if you have to deliberately "slow down" the kite, then what's the point? Depower is already huge.), but when my budget allows I'll probably get one of these for the light stuff while keeping to the PL Synergy Arcs for med-strong wind. Bummer that one of these probably costs at least 2x what an Arc does, or I'd have one sooner!

On the other hand, I've heard some wild rumors that PL is also considering a bridled design for a light-wind kite. If they keep the pricing down, we'd finally have the competition needed to help-out those faced with buying a less-capable light wind kite for price reasons only. Ozone doing anything???

Cheers,

Gideon

PS - When will FS ever have some demo days in the SF Bay/Central Coast area?
