a little depower on the main trim compensates for rear pigtail length being too short.

with tight back lines kite is really sluggish very slow to turn and extreme bar pressure.

there just isn't enough effect with setting parameters to cause it to clam. changing it just makes the kite stall prone

with line length issue you know it immediately, its not something that just pops up.

i think the( top)skin at the tips are pulled flat and as wind builds with load and angle it just pushes it close. internally shortening (maybe 20-30mm)#1 and #2 webbing at the tips maybe 3 cells in each side is gonna help keep profile shape on top skin from flattening out. it would be an easy reversible mod to test .

i have a slo motion video of tip fade, its why i made the video back in summer. it didnt really catch much attention.

another thought on this is the tips collapse because of a sudden loss of interia pressure. one answer to this could be he left the deflate zip open.

Surely no one has ever done that!

Carl you might be onto something with that.

what does a launch look like with open zip on a charger ? you don't get that far, you know immediately when it goes up , if it goes up and with it clamming instantly.

it doesnt show how much time there is between collapses, but the beginning of the vid looks like it was just after launch, and the end ov the vid shows it clam, regain pressure, then clam again

I can see what you mean Carl. But the rider stated that he has the rear lines super tight to offset the collapse likelyhood.

So it had to start, be landed, tinkered with, and launched again. If a Zip were open I would think it would go flat in the meantime.

I wish I could get my hands on it a and fly it. I'd like to see it in person.

I wonder what vpc settings he has lines connected too

Zip open - yeah I've done that ... the Insta-Clam is how I notice it too :embarrased:

I launched my 15m Charger yesterday with internal pressure too low. As soon as I initiated a turn is did exactly the same thing as in the video.

EVEN THE SAME COLOR!

Maybe its the color.

I'm not saying I think it's low pressure, but it sure looks a lot like it.

Looked like his had construction issues - the leading edge seemed to be pinching under the strap. So I won't be buying blue then
Yikes if it's inflation issues!

Agreed. Every time it has happened to me it seemed like internal pressure wasn't up there yet ? My sticky valves play into that one ? I wonder how long he had been flying on water when it happened?

The same thing happend to my 15 when I first got it and pulled all of the straps tight. It bows into an arc too much not allowing the vents to inflate all of the way I think. I think that top strap is too close to the vents which can cause that issue

my initial thoughts as well , it just lost pressure. a valve or zip popped. but after all checks out on my ch15. it continued and at the oddest times and once it started the recovery was slow which would look just a weak low pressure launch.

i have had a range of 2hour sessions with 5-6 non launch clamming events to a 20 min back breaker session with a 10 non launch clamming events.


LE profile deformation (at the tips) causing it to clam in flight is my last guess. i have about 100 hours working with this issue.

i am anxious to get its replacement . the loop speed really has me spoiled.

Sounds like a mistake in manufacturing ... HERE are some shots of the troubled kite in the vid.

no wonder! def problem there. would really affect profile!

i'll look for twist/pucker in some videos of my ch15,

thanks KK

wow those pics are intense.....problem solved?

looks like one of my cousins screwed that up well.

good thing is that at PLP we aim to please so the customer will be happy in the end.

Yeah looks like PL Oz is on the ball the guy posted on arcusers.net that he was being sorted out
