The line run through little dyneema loop, some are glued on the tent pol, some stay on the kite itself.

for the moment, the release system is just a larkhead knot... but it doesn't stay undertension very well... I must improve it with another idea to release ... for exemple, attaching the release system to the board... I don't know, any idea is welcome.
always nice to see new ideas!

Foil kites have been around for decades and they've only gotten easier to handle.
I guess you don't know the Kestrel ;) It's great to handle when filled, but launch is a little different and more difficult sadly. Don't get me wrong, I love it. I just say it has some handling issues with launching, especially in higher wind.

But even if we get to other foil kites: Launching a foil kite in winds above 30 knots, not matter which size, is risky and not easy at all.

Correct, I don't fly Kestrels. And I agree at 30kts+ things are different. But you play to the kite's strengths. The top end on the Kestrel 6m is 30kts but I fly the 7m R1 in 30+ inland winds and it behaves well if flown with respect, its a hell of a lot of fun and well-mannered on the ground or in my case, ice/snow. This said, the fly surfer Peak 5 4m in 30+ is less dangerous and less stressful. And the 2.5m is a ton of fun to fly in 40+. It's a matter of the right kite for the conditions, needs, and skillset.

I do not doubt that the Kestrel is a beast to deal with in 30kts. But for the money, I don't think we can expect it to handle and behave like a kite that costs 3x as much.

This said there are kites that cost a lot more that I hate when on the ground. The original Ozone Hyperlink, ALWAYS became a mess on the ground in high shifty winds. Loved it in the air, hated landing it for any length of time.

But my original point was that foil kites in general, are not difficult to manage even in high winds. At least not in my experience. From what I've witnessed, most issues with high-wind foil launches are due to pilot error and lack of experience. People out trying to learn without someone who knows what to do in certain circumstances to tell them what are usually simple actions, if you know about them. Again, IME

Maybe I was not clear enough, high end is great on Kestrel, ONLY the LAUNCH is a little different and more difficult. You need to practice a while to get it right, even when you have lots of foil kites experience.

BUT after launch, when it is filled, it handles BETTER than most "expensive brands" I tried!

Hi Alex, have you further elaborated on this? Would be great if you could launch a Kestrel in the wind window just like a tube kite. I just had two very sketchy launches on narrow lake launching sites, on shore wind but not enough space downwind and water was deep close to shore (Kestrel 12, gusts up to 25 knots, half in the trees and I got lifted 2 m in a gust, my friends declared me crazy, but everything worked out well and I didn't care). Tubes don't have these issues.

Otherwise with enough space launching a foilkite is absolutely ok if not totally overpowered, even above 35 knots, because until it is fully inflated there is maybe only half the surface efficient and by the time the kite is fully inflated it is safely high in the wind window 11 or 2 o'clock. Tom

Hi.. Yes, it's a very good way to launch safely ! But not suitable above 8m because it's impossible to hold the tent pole properly with a bigger kite.

There is another trick to launch more safely a foilkite, by overtensionning the B bridles, and release it once inflated, but I didn't have time to finish the system. Becaause I don't really have the best release system in mind

my idea is simple... a line between these 2 points (on B bridle), shortened about 50%... for launching safely, and once inflated, beeing released. I've tested it, it's really safer, but I don't know how to release the tension... :/

Idea:
  • 2 small sliding rings, 1 on each b bridle.
  • loop a very thin line through the 2 rings and back into first ring, then down towards bar
  • at the top end of the depower line, attach a piece that can block a line (small clam cleat, or plastic piece that can hold a knot in the line - knot would work as the distance of rope is predefined)
Then you can start the kite with line tensioned and distance between B bridle shortened, and then relax the line for normal configuration.
if the line is very thin (it can be as no load), there is not much drag either.

One of my entry for that idea... No fifth line.

One of my idea, is to slide one B into the other B, and once the kite is turned a lot, releasing the system... But I didn't have time to continue this idea...

No fifth line.
2 small magnets on the B bridles? With breakaway force such as when you power on explosively after launch, they separate?
