How to prevent brake release via slider, yet still allow slider pulldown?
Deyan replied to The111's topic in Gear and Rigging
First of all, have those risers modified for other toggles or get a different risers. I have nothing against Aerodyne, but their velcroless risers are by far the worst when it comes down to securing the toggles. They copied the UPT toggles, but changed everything else on the riser itself, so now those toggles fall off the risers almost without ant problem. Try this on your risers: Set the brakes, grab the lines from the rear riser and give the riser a good shake. If the risers are older than say 50 jumps, there's a good chance that the toggle will fall off. Many of the people with a toggle fire problem on an Aerodyne risers I know, have PD Slink hats over the risers, so the toggle being pushed out by the grommet was not likely. The best toggle setup IMO is the one from Parachutes de France . Basically what Terry (councilman24) is talking about. I just don't know when the Russians came with this solution ,but I believe that they copied the French. About this. The local DZ organizes a canopy course once every month or so. The target group is beginner jumpers working toward their "A" license. This is the first time that they are told to put the slider behind their neck. Many of those folks don't have their own gear yet and they hire from us. 100 % of our mini risers have those PD bumpers, and I don't know they do it, but when the gear comes back to us after the weekend, almost all of the sliders are under the bumpers. I hope that any of this info helps. "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen -
The picture shows a skyhook made from blue aluminum which indicates that this is actually a Skyhook 2. Skyhook 2 doesn't require tacking trough the bridle. Please check Vector 3 manual MAN-004, Rev 1 page 26 for reference. Cheers "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

Exactly my point. You can even hear Bill's comment:" Even with the slider UP, these guys would've made it" I don't think so! "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

Actually nothing. It's not the skyhook itself that I'm against. It's a safety system like any other. It might work and it might fail. It might save your life or kill you. What I'm against is all the misinformation that's behind it. For example that it fails only once every 500 times. Or the promo video where they show 100 ft cutaway with a slider down. I know what slider down is, and I'm sure you know as well, but the average 20 jumps wonder has no idea what that means. All they see is:" Oh cool, It makes chopping low much safer" [ a real quote]. Or that it happens so fast, you can't get twists on your reserve. Have you ever talked to a jumper who was told by the manufacturer that his 250 $ safety system didn't work because might have been misrigged instead of :" Oh well, sometimes it just happens and we still don't know why or how to fix it"? Or to a jumper who will never jump an RSL, but he will never jump without a skyhook either believing that it will never fail? I'm all for whatever choice you make, as long as it's based on knowledge and not on wrong or not enough information. Does that answer your question? Just look at the OP. He thought that his skyhook worked fine. He even was so happy that he decided to share his experience with us on his post on this forum. And of course there's a slight chance that I'm wrong and his skyhook did work fine and what I see is not what happened. It's all about educating people and helping them see beyond the marketing. That's all. P.S. I don't work for any manufacturer and I don't have any financial benefit of people buying or not buying a skyhook.

My second pictures shows exactly the same. An inflated RPC with the bridle stretched under, much closer to the reserve than to the main. Care to explain how that would happen if the skyhook completed the deployment? It's not what I believe, it's what I see. "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen
-
I saw all that. Just because the skyhook started the deployment, it doesn't mean that it didn't disconnect half way. Normal RSL deployment- as fast as the skyhook, but 250 $ cheaper "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

So where is the freebag ?! That's what I want to know. Also the distance between the main risers and the top of your reserve is a lot more than 9 ft. Are you sure that you've had a MARD deployment ? Cheers ETA: Never mind, I saw the freebag the frame before. You've had a nice RSL deployment ETA 2: the second picture. So tell us again how well the skyhook worked for you "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

Pricing question for 2001 container/reserve
Deyan replied to theplummeter's topic in Gear and Rigging
The Cypres is done at the end of July. If it's from 2002 then is Cypres 1 so + 3 months from the DOM. "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen -
I don't have a dog in this fight, but the life of Cypres 2 is 12 years and 6 months. And YES, taking a reserve out of service just because it's 15 years old is simply stupid thing regardless whoever told you that.

Weird. I am a younger rigger, not old grey-bearded one. I have ratings and I haven't been jumping anywhere close to 40 years. I got plenty of round manuals, I have packed (and continue to pack) plenty of rounds, and I have jumped and landed plenty of various rounds (both reserves and mains). sorry, just wanted to brag :) ............................................................................... You sir, are an anomaly! I challenge you to show me your manuals for the following parachutes: Advanced Air PEP Asquito PEP Ballistic Recovery Systems' PEP Butler Headrest pack Eclipse PEP Flying High's Slimline PEP Free Flight Enterprises' Preserve 5 canopy Handbury PEP Irvin lap-pack Jump Shack PEP National seat-type PEP Parachutes Australia long PEP Parachutes de France Flex-Pack Para-Phernalia "Softie" containing a square canopy Pioneer Thin-Pack PISA back-type PEP Reltny lap-pack Rigging Innovations' Aviator Security 150, 250, 350 and 550 Spekon RE-5L Stewart Systems PEP Westway pilot emergency parachute This challenge is awesome! :D Hey Mads, do you thing I should join the challenge, or it won't be fair? I totally fit the profile "young, black bearded, jumped all kind of round parachutes, packing a lot of old rounds per year, only 16 years in the sport" ETA: Packed some reserves that most old FAA grey-bearded master riggers will never see in their career! Such as PN-58, S4-U, Z-5, Z1-P, PZ 81, B-8...... and the list goes on "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

They do make smaller canopies, but you really have to be from "the chosen" ones in order to buy them "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

I don't know who told you that, but actually there are crosspots on the Crossfire 2. One of the reasons for the higher WL requirement is the partially closed nose. At 1.3 you should look at Safire 2 or a Sabre 2. "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

I don't know about the pin MARD video, but you can see how "good" SKYHOOK is working in the same spinning mal scenario. https://www.youtube.com/watch?v=mEau0dc67e4 There are a few more. You just have to search "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

Consistent Hard Openings on Brand New PD Pulse
Deyan replied to BobxMarley's topic in Gear and Rigging
Of course it's a very possible factor, but apparently unlike you I prefer to make sure it's not a "hardware" problem, before I start search for a "software" problem Not to mention that by the time I hear about checking a canopy because of a hard opening, the weekend is over, the owner is at home and I get to see only the parachute. But since you like games with questions, I have one for you. How many times when the guys/gals/ at PD check a canopy because " it opens hard", they can watch the owner pack it?

Consistent Hard Openings on Brand New PD Pulse
Deyan replied to BobxMarley's topic in Gear and Rigging
If it's a new setup, I'll go PC/size and material/, rubber bands/ or whatever is used/, fit in the bag, line trim check, slider size check, how the harness fits the person. If it's the same setup only a different canopy, I'll start with the line trim check and the slider size.

Same question as ''Pnuwin'' ! Does the UPT or other similar semi-stowless bag (Jerry's ) add more bulk ? However, I have a slightly loose fitting main, will it add volume to the container ? In my case, it would be beneficial. Thanks ! Just think about it. 350 cu.in. canopy is a 350 cu.in. canopy regardless where you gonna stow the lines. If the bag is properly sized for the container, you will not notice any change in the bulk. I've jumped several stowless and semi-stowless "mass production" bags and some custom made prototypes and never had to change the length of the loop. The experience from others may vary "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

Chest rings on containers - pros and cons.
Deyan replied to degeneration's topic in Gear and Rigging
Pros- chest rings will make harness resize easier, faster and cheaper. Cons- Because it's more flexible, you might end up with your reserve handle under your RIGHT armpit during a severe spinning mal.

If somebody managed to do that, it wasn't me. Copy/paste is by far the most advanced task I can do with a computer "My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen

Do I read this correctly?! The margins are so small, that you need the money from the new orders to fix the problems with the previous ones?! What happens when you need more money, but there are no new orders? There was a guy in Australia who started his business "just to help my fellow skydivers" by selling gear on his dealer price. Long story-short....he disappeared from the face of the Earth,stealing thousands of dollars from his "fellow skydivers".
