Hello.

I currently jump a Sabre 2 150 loaded at about 1.2. It has served me well and I like it, but now I've decided to focus more on WS flight and thus my priorities have changed a bit what I want in a canopy: I want quicker openings and something that handles line twists well.

I haven't jumped that many skydiving canopies, and I've never had a line twist with my Sabre 2, so I can't speak about line twist behavior. However, I think my Sabre 2 openings are a bit slow. In BASE jumping I love the openings I get with my Troll 245, they are quick, to the point. When I BASE my track suit, I feel extremely comfortable with my Troll and I don't hesitate to pull in full flight. I'd not want to do that with my Sabre 2.

How does the Sabre 2 compare with, for example, Storm or Sabre 1 or Spectre? Is it a noticeable difference?

So anyone tried these helmets yet?

Just out of curiosity. Seen people do both.

So just to avoid confusion, I will clarify what I mean: On bags that have a grommet in the center of the bag for the first line stow, how do you stow it? Do you put the rubber band through the lines or to the side?

If you put the rubber band between the lines, it will look pretty neat and symmetrical. However, if you mess around to much, you may screw up your packjob by pulling apart the lines near the slider. And it takes a bit longer to pack.

If you just create a line stow like on other types of bags, you will pack faster, but you will get an asymmetry that may theoretically upset the deployment.

Thanks. So I'm talking about the kill-line. I guess it has shrunk from the friction.

And what you say makes sense. Shrunk kill-line can lead to hesitation can lead to line twists.

My kill-line is too short. I was wondering how large/small effect this will have on my deployment and possibility for line twists?

Cheers

Hi,

So I was thinking why some parachutes have a thicker airfoil than others, and what the thickness means in terms of aerodynamics.

So accuracy and seven-cell canopies are usually thicker than high performance nine cells.

Can anyone explain the science here?

I was thinking (or, guessing) that the increased thickness will increase drag ("bad") however it may (?) also increase lift because the air has to travel further above the wing than below it ("good")? The canopies with a low aspect ratio need this thickness out of necessity to create lift.

Enlightenment appreciated :-)

Cheers,

Hi,

So as a christmas gift for myself I'm going to buy a new audible. I can get the Optima II and the Pro-Track for the same price, so that's not an issue.

Which would you recommend? I do free-flying, no swooping.

I was planning on mounting it inside the pocket in my Cookie Ozone helmet.

Cheers

Hi. So I'm sick and bored and the last hour I've been searching for stories about skydivers/skydiving written by people who are not skydivers themselves but are not complete whuffos, for example the pilots. So anyone know anything like that? I was thinking that there must be some aviation message board somewhere (like dropzone but for pilots) where our pilots hang out with interesting stories :)

Anyone?

Anyone know of any goggles that have pop out lenses? Clear lenses for night and dark for the day...maybe even transitions? I'm getting really tired of using the tandem goggles.

I've used Adidas Elevation Climacool for a couple of years:

You can change the lenses and there are quite a few different lenses for it. I mostly use clear lenses for jumping and tinted lenses when using them as sunglasses.

I lost the foam part once when hurrying from one balloon jump to the next and had the goggles hanging around the neck, so I bought a new one. The foam part has now started to come loose at the nose though.

Quite nice, but you have to pay extra for having to advertise the brand....

Looks interesting. Do you have a problem with fogging?
