Hi Eric, I've received a statement from Pal Bergan saying :" All ground tests by pulling the reserve ripcord were successful." So which one is it? I find it strange that almost 2 months later they haven't identify the problem and came up with a solution.

So I just checked that FORS you are talking about and it looks like they took the design of Eric Fradet and made it more complicated. (maybe to avoid paying royalties).

PD won't do that. One, because of liability and second because every company has their own standards for acceptable permeability and measuring procedures. I doubt PS has shared their standards with PD.

That's correct. However those loops don't fail that easily ! https://www.youtube.com/watch?v=9ruUZaTn_4M

That will make sense if PIA was about sport skydiving.

Properly manufactured risers don't fail at the grommet. They fail between the middle and the small ring. Most manufacturers have the RSL ring integrated in the confluence wrap

You think the site is impressive...? You should visit their factory in Germany if you have the chance..... That's impressive!!

There we go.....another brand war. For me there's one AAD brand. CYPRES!!! It's very simple. Get the number of units made, divide it by the number of Service Bulletins. That number should give you an idea of how likely is that the "maintenance free" will turn into "I can't jump in the middle of the season" maintenance. By the way, my CYPRES just came back from voluntarily maintenance. Just as a side note: Can anyone show me a 20 years old Vigil or 15 years old M2? The expected lifetime, doesn't always match the real lifetime.

Reserve Parachute Deployment - Line Twist
Deyan replied to Gavrilo Andrić's topic in Safety and Training
To me it looks like self induced line twist. You should stop pulling on your risers at line stretch. You might get away with doing that on a Sabre 2/3, Safire like canopies, but on higher performance canopies, you will "get bitten". How many jumps you have in total, and how many on this canopy ?- 9 replies

This! https://www.youtube.com/watch?v=2sAr8PiJiVI The tab from the soft link on the front riser wrapped around some lines from the rear. How likely is to happen again?! Not very likely. Reserves have wider risers and will be more difficult from the tab to cause problems, but why take the chance? If you tack the links loosely to only one side, is still easy to check the routing. Like always in rigging, you will get 14 different answers from 10 different riggers and they all will tell you theirs is the correct one. For the record, I tack reserve soft links and never had any problem with doing so... I also have no problem with riggers who choose not to...

Shock absorbing risers - with crumple zones - to soften hard openings
Deyan replied to CoolBeans's topic in Gear and Rigging
Here's why this is not going to work. 7G on someone 110 pounds will require completely different strength than 7G on someone 220 pounds. Just a my thought -
No way Speed 2000 170 will fit into I-23SN. Speed 2000 150 is a tight fit with no space left. If your information comes from watching sizing charts, mine is from packing the same configuration many times. Once again, Speed 2000 170 does NOT pack as small as an Optimum 143

If you are on the market for a new reserve, what's your reason for not getting a PDR? Is 30 years on the market and close to 60 000 reserves out not good enough to convince you? If it's about the price, the 100-200 bucks you gonna "save" by choosing it over a PDR for example, you gonna loose the moment you try to resale it. About the RUSH, I have packed many of them over the years. Nothing special. The ones I have packed had orange stitching (which is very nice for inspecting) and some custom made Spectra lines. Will I recommend it? Not likely. Having seen an average guy stalled a 130 sq.ft on landing, I would assume it's not build to handle heavy wing load. ( not that there's an excuse for jumping a small reserve with high wing load, but other reserves handle higher WLs just fine)

Stitching a lineset below the actual cascade point - is it a problem ?
Deyan replied to al05r's topic in Gear and Rigging
If the rest is fine ( stitch quality,thread size....etc) 1 cm lower than the start of the cascade is not a problem. That's how at least one major manufacturer lets them out of the factory floor. -
If that statement was correct, we would be having people falling out of harnesses every other weekend... I have no problem working on "closet queens" from the 90's, as long as people understand the limitation on the rigs build back then.

Parachutes Australia Airforce reserve TSO or not
Deyan replied to Youradhere's topic in Gear and Rigging
I have never seen one, so I don't know what's written on the label, but unless I'm wrong, PA has a 20 years lifetime on all its products . So that reserve will be unairworthy to start with! -
Incidents from Jumping a CYPRESS that is overdue for Maintenance
Deyan replied to jakebaustin's topic in Gear and Rigging
The biggest problem in this forum is that when you ask a very specific question like you did, and even though you said you don't care about the legal issues, people can't simply answer your question. Didn't take long before the first person said, you can't pack it according to the rules. Then somebody else steps in with his opinion on the rules.....and then the fight starts. And the thing is, they might talk about the rules of different countries. Further down the road, somebody will start a brand war. 5 months later and 375 posts about all of the above, someone might actually answer your question. Good luck! -
3-4 weeks seems about right at the moment!

You are talking about the 3 ring release patent. The thread is about Collin's lanyard. Completely different thing. "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

I personally find UPT's sizing chart to be spot on only in regards to PD reserves. Everything else there is way off. If we look at the V348, we see a Techno 155 and a PDR 160 listed as standard. In reality Techno 155 packs smaller than PDR143. And then is Speed 170 listed as "full", but it actually pack smaller than a Techno 155. The best way is to try it!

Look further! Stay away from magnetic riser covers for speed skydiving! "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

VSE is using similar setup on Infinity, although they use the kill line to connect to the canopy. Very smart design. Aerodyne also did something similar like UPT for a short period of time. Like Betzila pointed out, those should be used on D-bags with grommet #4 only. Unfortunately so many jumpers think they know better when they swap parts from rig to rig.
