In addition to what was already said. Cuben needs to be taped at this low weights. Sewing is optional on top of that. but for low wind sails generally not needed.
It also does has stretch off-axis to the fibers in the laminate, so having a loadbrearing seem layout and fiber orientation is also important. the higher the load on the sail the greater its importance.

Great looking Kite Andre! I think you have won the lightest kite ever made contest Smiley. Looks like a lot of hard work and experimentation.

@Geoffrey: Thanks, yeah it toke some time to get it this low. especially in the materialorganisation. Lowest weight, I'm honor, but i would not go that far.
But, the next ones I'm working on will be even lighter Smiley I'm trying to break the 3oz barrier for my personal one. For others, that will not be obtainable since the rods needed for that are no longer produced or even available. But the breeze version should stay below 100grams with even better performance then the current prototype.

Have you considered trying shorter bridle legs to shave off a few more milligrammes ?  Wink

If it's possible to capture this sort of thing I'd be fascinated to see video of this in motion.

Got a change to fly it yesterday, wind was very crappy sadly, between 0 and 5mph, with changing directions, short gusts, short zero winds and all that nightmares.
but it flew, rather well. But i think the first version sail was a bit better, but louder.

Some pictures in flight:





Enjoy,

Andre

Curious as to your thoughts on why the first sail was better, you were shooting for improvements.

Its mainly gut feeling, since the wind i got to test it in was rather bad.
But it felt less precise then the old one, that could be a by product from it been basically silent except at the upper end of its wind range.
It has a lot more pull then the first sail however. It also seems to be a bit less nimble.
I guess i have to fly both in the same wind after another and see which one behaves better.

Watch this space .....

I got my new set of spars ...
They clock in at avarage of 4.8grams for 32.5 inches and are stiffer then the Zero golds, about the same as the Avia Breeze II

A quick calc shows that the full kite should come out at around 65 grams ...


PS not sure if i shouldopen a new topic for this kite or just keep on using this one.

The Spectre in flight:
Bottom right in the middle video,
nothing spectacular, just some slow motion flying in near non existing wind.
