I use EP5 now, used to use EP3. My choise is 5, they are more comfortable and easier to insert. I think they block more sound, I have noticed that it's harder to hear what others say on the ground when in. But on the other hand, I can have them in the ear but not inserted and because they are easier to insert I can just push them in just as the plane comes.

Red on the chest strap, green on the back of the rig (not really sure how). We can use battery-powered glow sticks instead of actual chem lights. Color of the strobe is our choice as long as it meets the visibility requirement - I'm sticking with red. So at this point, I think I'd rather find LED glow sticks that I can just turn on under canopy without worrying about covering up chem lights, and a good xenon strobe. I'll have a small flashlight in my pocket for inspecting the canopy. I have zero intentions of doing group jumps at night, so visibility in freefall is less of a concern. For that matter, I plan on doing either a low pass or a high pull, maybe first one then the other, depending on what the winds are doing. My strategy for avoiding other jumpers is to not be anywhere near them Regarding dangling the strobe below me, there seems to have been at least one fatality from doing something similar, though I haven't found any details. http://www.romad.com/romad.com/finaljumper/obit.php?usernumber=34

Try using earplugs and see if that helps. It usually works.

Any news on this yet?

In that case I recommend a media player. I think anyone of them would work. http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR0.TRC0.H0.Xmedia+player.TRS0&_nkw=media+player&_sacat=0

If you 'neeed' to fix it, I suggest just tape over it with black tape.

He has the mini cube thing. Session? Is that the name of it. Not sure it has any HDMI at all.

Some TVs can act as a 'computer' and read the files. Don't know about USB->HDMI, but don't think so. One option is to buy a mediaplayer and connect that to the TV. I bought one a few years ago and it plays all videos from all cameras we have put in to it yet. The only problem is that it does not handle XFAT (I think that is the name), meaning larger memories does not work if you have not forced it to FAT32. If you do plan to buy one, check that first.

Thanks! It's clearer now. So that means french is both hard to read and write.

Anyone know how to read this? Does it mean all A and B lines are the same lenght? And what are the numbers by C and D? There is only three numbers. My french isn't good enough

Thanks everyone. I didn't get a chance to try it this weekend.

I don't think I have read it. Will look at it later. Thanks. The reason I ask is I'm planning on switching slider from normal without collapse to mesh smaler span and larger chord.

What would that do to the opening? I know larger span means faster opening, but chord?

Have never jumped one, but I think you are right. Lightnings is as far as I know equal-ish, and they are hard to land. To fly with other CRW canopies it has to fly very flat, which means it is already in brakes as you flare. I think what you need is some front riser input before you flare. Don't try it without guidence first. If you mess up you will hurt yourself. Ehm, see my previous reply. Also, if a canopy is flying in brakes when flaring it is shortlined. You can do that, some teams do, but my Lightnings never were. In fact I put extra links on the back risers to make my first Lightning 126 dive more! On account of having a lower WL than most jumpers I jumped with and not wanting to jump a Lightning 113 at a couple hundred jumps and not wanting to add more than ~8 kg of lead (did jump with 12kg for a bit, but man...) BTW I never had that much difficulty in landing Lightnings, I never added forward speed either (you have to hold it until REALLY low with canopies with a very short recovery arc like these, no thanks...). Not sure I'd recommend landing on double fronts on a regular/hybrid Tri to a 200 jump jumper I don't know either. The issue is probably something else, like timing, finishing or brake line length/entire lineset. I think you missunderstood me or just wanted to start an argument. I did not say the canopy is in brakes. It flies as if it was. Big difference. A lightning flys flatter because the lines are not as a reserve (which is about the same), they are shorter on the rear lines which makes it fly slower and flater. This is pretty much the same thing as having the rears slightly pulled down when landing on a reserve. That is what I meant about it flies as if it was in brakes. Really good for you that you can add a extra link on the rears to overcome this issue, but not everyone can do that. It's about geting a flight that is close to what the other people you fly with. Also (again) I did not mean you are supposed to pull the fronts all the way down to your knees and do a multi rotation. It's about putting your hands on the fronts and just bend them with only your hand twisting. This probably makes the canopy fly as your with an extra link on the rears.

A 170 what? Some canopies can be trickier to land. My advice, including all above, is to go in to some brakes before flaring. Pull down the toggles to head height at perhaps 12 feet. This will slow down your canopy and it will be easier to time the flare. But this will also remove some of the flare power, not much but you may notice some change in the flare. I believe even with less flare your landing will be better because it's easier to time the flare.

Fair enough. :) Allow me to re-phrase: The lanyard is a plain straight cable, with no nub, ball, hook or snags on the part that feeds up into your riser; it's identical to your cut-away cable, both being the same material and how your cut-away cable feeds up into the hard housing on your riser. We considered half a dozen different activation methods before settling on this one, as we (and our riggers) felt it was the simplest and safest, while making use of as many existing skydiving materials and methods as possible. -Brendan I can agree with your statement that it can't get stuck. I actually built a prototype of a similar switch a few months ago. I used a pen that I gutted and made a hole in it to feed in the switch through. It wasn't pretty but it worked :-) As long as the end of the switch is bent up (away form the cutaway cable) I'd say it's risk free.

Actually, we are using SMS to send out the positional data. Partly for cost, but also because SMS rides on the baseband frequency of the cellular signal. This means it requires VASTLY less signal quality and electrical power to get a message out than if we were trying to use a UDP connection or something. Even in places where a phone shows barely one bar or even "No Service", we've found that our device can often still get out an SMS position update. Two separate issues here: one is the cellular module itself, and the other is the SIM card/rate plan/carrier agreement. I think if you try and scale your device up, you'll find there's a huge gap between "hobby project that works on pre-paid SIMs" and "Fully engineered device ready for mass production and worldwide use". Our first proof-of-concept was identical to what you describe, using an Arduino as a base: http://findmycanopy.com/development/ Regarding the cellular radio: While there's a plethora of tiny and cheap cellular modules that work fine in hobby or small regional products (uBlox has some great ones), if you start trying to scale them up to an international product you find limitations. They're usually region-specific; they work only in Europe or only in North America, not both. They're also usually 2G or 3G only; they won't do both. Regarding SIMS, pre-paid SIMs have a lot of limitations, aside from what will happen if you go to your carrier and ask to buy 5,000 of them (try it and see). They're usually carrier and region specific; they won't roam to other companies networks and they won't work overseas (or if they do they're very expensive). They also expire, many require that they be connected to the network at least once every 90 days, regardless of if any actual data/messages are sent or not. We've designed around these problems by using a Hex-band cellular module; it works on both the EU and North American frequencies, it works on on any 2G or 3G GSM network, and we've got roaming/carrier agreements in 130 countries that will allow this device to work internationally with no extra fees or roaming charges. This capability makes it more expensive; our cellular module alone costs a lot more than the price you quoted, and that's even with us getting large volume discounts. And that's before we factor in the power regulation circuitry, the microprocessors, GPS and cellular antennas. I'm the engineering half of the team who's created the Get It Back, so I'm more than happy to talk shop if you've got any more technical questions. :) -Brendan Why buy the simcards to the user? Why not let the end user decide what carrier he/she wants? I understand you want to solve everything, but is it really needed? I'm quite sure people know how to insert a simcard. If it's a enclosed device I understand the issue the reason but if it's possible to open it... Regarding roaming, network quality and how long they are activated depends a lot on the carrier and country. Again.. here it's not an issue. All carriers here have good enough network for most areas you will ever visit. Roaming is as far as I know possible. And some (or most) carriers have M2M sims. They are generally quite cheap. Regarding the price of your parts, I can't comment on that. But I bought 10 units and costed me $38 each. Buying larger scale probably makes it cheaper. But this is an of the shelf product, so costs are different.

Once we get through manufacturing and get the product out to consumers, it’s actually very easy for us to keep the devices connected to the network. So even if we close the doors, as long as you pay the yearly bill we can pay the carriers to keep the device connected from our end. We invested a huge chunk of time and money into a back-end system that would, in the event that we had to stop manufacturing devices, take care of itself, with minimal input from myself or Brendan. Yes there is a risk to being an early adopter, but we tried to make it as minimal as possible for the consumers. I feel like it’s my personal reputation, of 18 years in the sport, on the line here with my community and family of skydivers if we let you down. Not just money. I'm not sure exactly what trackers you are referring to. Every tracker we have looked at is as much or more per year, and are only good within a certain country or region. Our subscription allows the device to be used in about 130 countries, without the hassle of signing up for roaming services. How are you transmitting the data from your device to your cell phone or receiver then? GPS is receive only and has no transmission capabilities without a cellular or radio transmitter. Sms. Simple and cheap. It's a GPS and GSM device. So you just call the phonenumber and it hangs up. Wait one minute to get a GPS position, then it sends you the google maps link. Over here we don't need a subscription for it, you can buy a prepaid sim for ~$7 and it will continue to work as long as you use it at least once a year. However I must say that it now seems as a better product as you have answered som questions here.

I'm afraid it will meet with resistance because that will put a belt or two within the reach of the door. It will also require retraining all the jumpers. Also, most people feel that they've met the legal requirement, so why bother? Most of them have never been in a forced landing. That can be solved by placing a ring you mate the belt with. Or just simply hand it backwards and someone can clip it together with one of the belts further forward in the plane. Or just use retractable belts just as in cars. Problems are ment to be solved

In all fairness, I believe mathrick has known all the time that he should be leaning forward, but used a "wrong" word in a former edit of his post. Even with the old word still read it as he understood. GoHuskers however believes he can help the flare by leaning backwards And that the canopy dives when he leans forward.

I believe Brian said lean forward not back. And there is a good reason why everyone says lean forward, and not back. You want your CG above your feet when you land or even forward of your feet, that make taking a step easier. If you run, do you lean forward or backwards? Try running with your body behind your feet and you will understand why saying 'lean back at landing' is odd. When you flare the canopy your body rotates and you are forward of the canopy, so leaning back at that point means you are even more leaned back. Leaning forward means you compensate the rotation the canopy does to you. And leaning forward or backwards in the harness does nothing to lineinputs. You are connected to the canopy at the tree rings, that is a one point connection. Whatever you do, the rings will just rotate to compensate your movements.

1. My wife had the same problem and couldn't get the tail to cup enough to cook off horizontal speed. Not really sure if single-wrap stall is the gold standard of testing but if someone films you land, you should see the tail cupping and get plenty of educated opinions from the video. 2. You shouldn't lean into the chest strap throughout the landing. If your weight is forward, your wing will be forward so your pitch will be steeper while you're flaring. At some point you want your weight more on the rear set of lines to aid in the flare process since it gets the wing more overhead and decreases your pitch. For me I lean into my chest strap on final and shift my weight back as I begin to flare. I suggest you read the Parachute and its Pilot. The author explains canopy dynamics and breaks it down with illustrations that really increase your understanding of canopy design and flight. A great read and worth every penny of it. Best of Luck Ok so does Brians book say anything about leaning backwards flares the canopy? If his book does not mention it, why do you think that is?

But did you do the 15+1 min warm up? I have also had jumps where I lost 9 satellites because I didn't warm up.

Maybe the guy instructed the girl to go first because he tought she would drift much more than you. So if she would exit after you she may be above you at pull height. Not saying it is correct or wrong. But I donKt believe it would be a problem to have her go after. But as others said, the type of canopy flying is also something you have to think about. High performance canopy or not.
