Re: Pre aneurism in bladder

Maybe it could be the valve? I have experienced Boston valves which when very used needed to be tightened more (or a new sealing ring), as otherwise it can have a very slow leak. The same could probably be the case for other valve systems, and it shows by sometimes holding air just fine, other times...

Re: Had Low Wind Breakthrough For Big Guys Like Me 100 kg

Snip..... I really rely on having quite a large power zone for the kite and I achieve this primarily by having 32m race lines. Makes a huge difference to me getting started. True, this goes for all weights but the bigger the more important. It is not only the longer powersweep that helps hugely, bu...

Re: What influences going upwind

You could switch rigs part or whole and test rider ability . Best upwind board I have found is or duke or mako , but I only tried a few. Rider weight and ability is big factor , you can tell that when you switch gear. No, you cant. It takes months, maybe half a year for some, till you can use a new...

Re: Pre aneurism in bladder

All bladders without exception do like yours, when pumped up outside the LE. Bladder will still work just fine now, even after this aneurism, so just use it. But next time you seek a very small pinhole, or any bigger puncture, first locate the area like you have done, with kite pumped hard, either w...

Re: Gin Kiteboarding Spirit

If it flies a lot further forward in the window, it can not drift as well. You can't have both. So now I am puzzled as to whether it flies far forward, or drifts? As it is closed cell, I believe it could be the first, but if low AR it could be a compromise. BTW, a Soul does not have good lowend, but...

Re: Wing surface area definitions?

Agree, it is impossible to compare foil wings, as every parameter is important. Even volume is not a measure of lift/drag at all, as camber and LE rounding means a lot more. Apart from, as said, AR and sweep. So the more numbers available, the better, and Gong is quite good at this, compared to many...

Re: Wing surface area definitions?

No chord or AR? Thickness is handy too, with all that you can make an educated guess about how it'll feel... Snip... You get width, chord and AR on rear wings... Yes, span is also labelled, and max thickness and volume, on Gong wings. You dont need (max) chord or AR, as it is implicit when you got ...

Re: Wing surface area definitions?

True, about the home built calculation. But in the example above with the two wings, the first one is the thick one, and the second one the thin one. With less sweep and higher AR though, but a lot thinner profile. So if it was based on thickness/volume, Then one would think the "Felt area" should b...
