No. If you remove the person from the video you will see a black human with a rig on. The camera can't video what's behind the person so removing him from the video will make it black.

Depends. If the jump was meant to be just a skydive with a BASE canopy, then yes it's incorrect. But if his goal was to fly the canopy with steeringlines outside the slider he was correct. The canopy responds very different with or without the guide rings. I guess he couldn't really decide what he wanted, so he went for the left brake outside the grommets and the right brake inside. Really? I can't see for sure but something keeps the slider from coming down and I think it's the steeringline.

What I thought of was just as you said, to push the toggles through the slider grommets to free them. Because a BASE canopy is very slow the fiddling with the toggles is not a big problem. If you do drop one toggle you just have to do "test 2", land on one riser and one toggle, or two risers. What he ended up with was probably the only bad thing that could happen, slow deployment, slider stuck, loosing a toggle that ends up in the lines. It's a long chain of "bad luck". But somehow I believe one contributing factor could be that we was so quick on the risers. Quick on "steering" is normally good but sometimes you probably should just chill and wait. And using LRM with a slider is probably one of those times But I agree with all that you wrote, it's "incorrect rigged". But he probably planned it this way.

Sidewinder? Or something like it? Could be wrong.

I was considering this until I looked up the density of lead (verses water). Mercury is heavier than lead and a liquid

If a canoy flies at about 40 km/h, thats 36 feet/s. And in a head on collision you then move towards eachoter at 72 feet/s. This beep will warn you about 0.28 s before impact if both GPSes are perfectly accurate. But normally yo have 2 m inaccuracy on the "best" GPSes so that could mean the "beep" will warn you about 0.19 seconds before impact.

Did you even read what he wrote or did you just find a few words you could missquote to start an argument? Here, let me quote what you should have quoted. So what he is saying is do more than one H&P.

Most of those posts are 'spare time' posts, talking about safety, acrobatics, teaching and flying. Though its also a job, the last 12 years of flying wingsuits is 99% love of the sport type stuff in terms of published materials, organized events etc. Never realized that was a negative thing... Its a shame the public bitching and gloating of the 1% of orders where there things didn't go as planned/hoped (be it spam, communication issues or an honest screwup) seems to be peoples main focus. Now even to the point of what I do in my spare time being an issue? If anyone has actual questions related to product or order issues, [email protected] is the address to use. It's not a negative thing. I have not read every post you made on this forum, but my general feeling is that what you write is something worth reading. As you say, you write about wingsuits, flying and safety. And that is in my opinion a positive thing, because it shows that you care about both the sport and your customers. If you write those posts on your spare time or on work time is in my opinion none of our buisness because your spare time and work time interact to some part. Just to let you know there are other opinions. And 6800 posts is not much for the time registerd here, some people get thousands of posts of 'nothing' in the bonfire in just months.

For now it's one of the worst used in skydiving. But just wait and you will soon see them poles on not only wingsuitjumps. And one day maybe the attachment....

I think they should be called low or high aspect ratio canopies. Low generally beeing 7 cells and high as beeing 9 cells. The reason is that a 7 cell crossbrace has more similaraties with a 9 cell because it has a high aspect ratio. To answer your question you really need to know what 7 cell, but if we are talking general advantages of 7 cell it would be better heading on opening. But with the newer 7 cells the gap between 7 cell and 9 cell is less regarding flare, but I don't know about the heading.

I think the risers are velcro risers, because I can't see any pockets for the toggles. The velcro can make it look fuzzy and in contact with other parts make them look fuzzy.

Cn anyone post a link to 'the old' thread with those pictures? And, since I guess it's a long thread, what page are those pics at?

Try it and you will see why everyone does as in the video. When the brakes are free you need to pass the brakes through the slider grommets while the canopy flies at a higher speed forward and down. Also keep in mind that when you try to pass the brakes through the grommets (depending on canopysize) this can make the canopy turn and you might end up on heading for other jumpers. But there are people who release the brakes first. Both ways has it own set of drawbacks.

What he could have done is, pull the right brake to keep the parachute flying straight and then fiddle with the left brake. This would have saved him loads of altitude. But it's easy to say looking on a youtubevideo

I don't like the bad range of those devices, and you need a "specfic" phone. A range of 100 feet in line of sight might be much less if it lands in a field. Batterytime might be an issue for GPSdevices, but charging it once a week isn't that bad. I charge the camera every day

I have built a prototype of a switch like that, but it would cost to much to build it. And then there is the risk of the switch somehow jams the risers or three rings. Have you looked into this? http://www.plexustandem.com/products/fido.html Sparky Depends on what you mean. Yes I have seen that webpage before, but no, never seen the device or how it works. I understand how the magnetic switch works, I have thought of something like it. But for this GPS or most GPS trackers there is a size issue. If you build a harness and rig from scratch you can make room for a device, but as a aftermarket product it will be hard to make something fit the risers, even if it's type 8. The option would be to place the device on/in the bag and have a cable next to or inside the lines down to the riser and have a switch to detect a cutaway. In my opinion it will be a much to big job to do for most jumpers and I believe riggers will refuse to do the job. But the magnetic on/off is something I have put a lot of thought to. It would mean you could start the GPS inside a closed rig with a magnet. Anyways, back to the original question What was it you thought of about the fido? Do you have any pictures of the device or where itis positioned?

According to the manufactor, 80 hours in standby mode. And if you use the sleepmode about 170 hours.

So is the cost per unit when you order 100 make it worthwhile you think? But if there is a monthly cost for the service would be annoying to me. Unless they charge you a flat rate of $X per sms when you need it. Dont know how things are in Sweden, but here in the states it isnt uncommon to charge you a lot before you need something because you MIGHT need it someday. I really like the idea though, hope the rest of your testing goes well! Looking forward to seeing how it all goes. Don't know the price when I buy larger quantities, havn't talked about that yet. But I belive it will be worth it. A lost canopy with dbag and risers costs a few pennies.

Not sure about this, it does feel weak. My initial thought was to place it on the (think of the bag packed inside the rig) top side, meaning you place the flaps ontop of the gps. But as it feels rather weak, I think moving it to the bottom is better, so that it's between the bag and the jumpers back. That way when you are packing the canopy will protect the gps. The GPS comes with some casing that could perhaps protect it, but it also makes it bigger. Will start building a pocket when I have time and I will upload some pictures. About 'when the canopy hits the ground', I never thought about that as beeing a "hit". When you land the canopy lands and deflates, and since bag is in the middle of the canopy that should be a gentle landing for the bag?

The unit cost is hard to say. I could order one as a sample but to a high price, if I want to order more I need to place a order of minimum 100 units. I need to be sure it's a good tracker before that happens

Can you explain? I don't see how it can happen. http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=4406247#4406247 http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=3680704#3680704 Search tag: pierce bridle EDIT: Ooops. Just noticed you didn't quote me... Never mind this post

Ok, finally got one GPS to test with and it looks very promising. This was just the first test, I have not yet started building a pocket on a bag yet to see how it looks in it's real environment. The device is 91mm x 46mm x 5.6mm. I attached 2 images. One of the device (sorry for the bad quality, will get a better picture later) and one map with the GPS coordinates. I placed my FlySight next to it for reference. And it's about 5.5 meters between the FlySight point and the Tracker point. And the actual point is about in the middle. Perhaps a bit closer to FlySight. The FlySight coordinates are an average of 200 rows of coordinates and it was in contact with 8 satellites at the time. Below is the reply sms I got from the tracker when I call it.

You could end up with a pierced bridle by closing the "old" way.
