Maybe someone is motivated to find a good light material and valve for such "bladder" and wants to test if it works as I expect? Will keep my eyes open aswell if I find something. I've used "roll sack" plastic tube for vacuum bagging, it is cheap and light weight stuff. Heat sealing is possible. Cl...

They also have an illustration of doubled "three piece" D-ribs (which allow 4 unbridled ribs, or 4 or 5 cells). However there isn't such thing in Koala kite so it is a bit misleading.
But it is fine tech, you can't argue that.

Both strutless (one strut) kites and single skins sit deep in the WW. They also have quite low AR and LEI's have quite a lot C shape and built in AoA (coning). That is because having a lot of C shape compensates lack of structure of kite and coning prevents luffing. Single skin kites don't tolerate ...

OK, they have wrong line plan (not Koala) under that button. Correct one can be found in "Manual en V1", at the end of it. This one looks reasonable and makes sense to the structure of kite. There is still D line row (at the center of kite) which is a bit weird nowadays but ok, not a big deal. More ...

At least bridle of the kite (Koala(?)) is quite primitive, about twenty years ago foil kites used to be like that. Other than that (which pretty bad website allows to find out) kite looks good mid AR kite. I wouldn't give much value for bold claims and fancy names for techniques, programs or simula...

"Chord cut billow" tech is interesting though but how much it really helps, hard to say. Kites with traditional cells (with more cells than 35) are pretty clean too.

These things relate to cell count, airfoil shape and amount of canopy curve, but it is true there is double curvature there.

I want the new version to auto park on the edge of the wind window like an LEI. Born kites have a single skin kite that does: https://www.youtube.com/watch?v=F_0cOIezOto I don't see it is going to happen with a high performance foil kite. SS kite sits much deeper in the WW and is very light weight,...

The back lines being slack is different from the B bridles being slack. You can certainly increase depower by extending B's (the mixer's) range. First is the problem where B remains under tension because of the pulley lines shortening. Second is FS only designs B to become slack at near the window ...

Edge? It is a high performance boosting kite, in small sizes I'd say it is for pros. Some easy low aspect wave kite is much much easier, very stable and it eats gusts, unlike high performance kite. Small Soul I wouldn't suggest at all for nuking winds, it is too fast and aggressive kite, it flies fr...

Ideally you want the line A-Z to be twice the length of A-C so the shrinkage of both lines will have the least effect on the speed system trim settings. There are no other differences between those setups. That wouldn't help. There is adjustment to level mixer (or should be) and if pulley lines are...
