R1 has double advantage for cell shape compared to Kestrel: more cells and thicker profile.

Long time ago I made 7m AR6 kite which had 16% airfoil at the center and even thinner at wingtips. Unfortunately airfoil I used had too much camber and this all resulted very bad stability. I had to limit AoA a lot and even then it collapsed in gusts.

However it did fly fast and gave big power spikes but in general it was a failure. It had 33 or 35 cells and full cell D-ribs from A to C, so quite ambitious design anyway. At hindsight too ambitious or silly.

For certain AR and cell count cell spacing becomes pretty much what it is. However cell shape improves if profile is thicker. Long time ago FS used to have spacing very much in proportion to chord, later less. Thin wingtip cells are quite difficult to sew.

Having thin airfoil has some advantages and some disadvantages. Thick airfoil has many structural advantages but there is so many other aspects you can't say some profile thickness is the best. For PG's there is hardly any reason to use thin airfoil.

@evan
You do great job on your r1, I follow all of your videos ! 😊

@kitexpert
I totally agree with you on thin profile, even if the kestrel airfoil is very stable on A line on this soaring exercice despite deformations.

I wanted to bring on paraglider what kestrel has bring for kiteboarding, great depower and handling... But after this test, I 've learnt depower and handling are not the main interesting feature.

So I will try a more classical paraglider bridle... I' ll get probably better results.

Enjoy your life, and be safe for this new year 2024 !!

For thin stable depowerable foil AOA why not use S profile, basically TE section of airfoil pointing up when completely depowered? To act as airbrake keep it stable.
When kite is powered it is folded down to normal airfoil ?

Kestrel has already a "S" airfoil, but the S comes closer to center... it's a modern tendancy for stability for thin profiles... and it works very well (you can pull A firmly without frontstall) without loosing as much performance as a standard backward "S" could loose. That's the reason why an old "s" profile is not so much used nowadays.

Also, old S profile have very bad depower for kitesurfing.

Will try this new bridle soon, feels better..
But again, it's not a paraglider first, not sure it will be enough to compensate the thin profile.
