Re: Screws loosening themselves ?

I used a product like TefGel on the plate-to-mast bolts and they worked just enough loose every session to allow a slack feeling. Cleaned everything out with degreaser and it was better, but every few sessions they needed a tweak. So they can work loose, and material "packing down" creates looseness...

Re: Cabrinha kite with ozone bar

All the usual things to check: so long as the depower throw is long enough, the trim line is long enough, the flag-out/safety line is long enough, and the pig tails are the right way around (or you don't mind making pigtails) and the lines are equal lengths...you can use any bar.

Re: Core Kite safety question

Y'know, I never even added obnoxious twits like snobdr or flying weasel to my Foe list, but I think I might actually have a candidate who has absolutely nothing to offer except mind-numbing ignorance and unparalleled stupidity. And every single conversation would be better for completely ignoring th...

Is there any application when evaluating foils? What say you?
Carry it down to the end of the beach and back :D

You'll notice the weight while riding; it'll be a small but niggling effect like riding a heavier TT. Carrying it is where it gets annoying...

Re: Riding without sunglasses

Friend of mine got hit in the eye by the foil during a crash. Badly. Doc said 5mm in and he would have lost vision for sure. He is now waring shades...as am I. Oh that's great, so now instead of just having a foil in your eye, you can also have little broken pieces of sunglasses in it too. Great id...

Re: Riding without sunglasses

Ansi means that it can withstand a metal ball traveling at 100mph. Does this sound like a bullet to you? It sounds more like a bb gun to me. And if you think for one second I am not going to defend myself then you are dead wrong. When someone calls me out I am going to respond, I don't sit there an...

Re: Stall question for high aspect wing in light wind

... Bernoulli is the cause. The action/reaction generating lift is the effect. It works the same for wing in any fluid, whether it's in water or air . Only real difference is compressibility, (air is 784 times less dense than water) ; so ... it's like an entire other field of study , comparing the ...

Re: Stall question for high aspect wing in light wind

That's a pretty poor explanation. This one's better . . . in fact, the whole section is informative.

Air, water or a bathtub of vodka, it's all fluid dynamics.

Re: Stall question for high aspect wing in light wind

I don't think you can compare the two. Hydrofoils do not get lift in the same way as a airfoil(wing) Beroulli's principle https://www.youtube.com/watch?v=17JRkEC1Egk http://amzn.to/2kdfGlL You had better watch the video and read the book again. I think you missed something. I found a .pdf of that b...

Yes. Move it forward if you want more front foot pressure.

What foil was it?

Alpine Access with short mast on a Dwarfcraft 54", on the 3cm from back setting. Only got five minutes on it, but it felt like a nice foil. Will offer my taxi service again, as I want to ride it again :lol:
