Some remarks/suggestions:

Bridle adjusting ring is nice idea, though smallest shortenings are perhaps too small. Real "fine-adjusting" tool :wink:

Kite looks balanced, nice elliptical shape.To my eye wingtips could be a bit wider, but thinner or wider it will do for sure. According to my experiences wider wingtips are a bit easier in practice.

I advice to do wingtips like FS does them, last cell without bridles. Then there is two cells "for free" and also last cell is smooth because it has no bridles.

I like big air intakes, and having only two makes it more simple. You could consider having them doubled and raised even more to the upper skin for low AoA's. Not much work and pressurization improves. I have an air intake in the center always because it is good choice when cell count is odd number like it should be.

There is a lot of strapping which is good. Bridle spacing is apparently 2 in the wingtip area and every cell in the center, which is a bit unconventional design. It could be opposite way, but there is some reasoning for both.

In general your new kite looks good and I don't see why it isn't an improvement from earlier kites :thumb:

It will be in the air soon!

Kitexpert, good points as always and this time we are on the same wavelength. I tested my kites without tip bridles towards the end of last season. And I raised my vents a few centimeters as I was losing a bit of pressure when sheeting out going upwind. -stef

Hi Downunder, I use XFLR5, Solidworks (for my 3d built and flat panel export, alignment holes, bridles ecc), and Adobe Illustrator for modifying and editing all my patterns for laser cutting and pen marking. (and all other graphics like the line plan you see in the previous pic.

My process is laborious and not automated, but I feel I know every mm of my designs inside and out, as nothing is calculated for me. However, I would like to explore other software solutions, including trying to develop something of my own even if for now that is a way off.

I like how you are doing your kites and trying to make them better :thumb: New wingtip is much simpler than previous one.
