Have you finalised in you head exactly what was the cause of your accident? Too low is just to vague to be able to have confidence that it won't happen again. Part of what you should do is re-evaluate what you thought you knew about yourself, that will suck but you need to do it and figure out what you will change to make sure it doesn't happen again. if all you can come up with is that you were a little low, then perhaps a lack of experience is what caused it and may well cause it again in the future. Think about what was different, we're you out of position trying to get back onto a safe line, keen to impress people on the ground trying to save a bad swoop so delayed bailing earlier? Being honest with yourself will be hard, you will have to question the belief that you were progressing well, truth hurts the ego hard. I've been there.

That's the gayest Jeb video I've ever seen, that's quite an achievement, well done!
-
Was that measured from the ground with a radar? I don't put any faith in the actual mph reading from a viso or Neptune, just that it measures and calculates speed based on barometric pressure, the same way as the AAD does so its more relevant in the context of aad fires than max performance.
-
The peak speeds can't be maintained for more than a second or so, they occur when you tighten up a large rotation into a tight throw, gives a very vertical pitch that can't be held for long. Also, I don't know how much faith I would put in the actual numbers, they are more of a guide or power meter I would think. My viso is leg strap mounted although when wrist mounted the numbers come out the same. It would be interesting to see what the numbers look like when the viso packed into the rig some how.
-
If you are starting your rotation around the 750-800' mark, it is very unlikely that you will reach a sufficient speed within the firing window regardless of canopy or wing loading. I have witness 2 aad fires during landings and both times the rotations were started over 1200' one was a 450, the other a 630. It would seem to me that you need to be reaching the trigger speed much higher to get the aad to fire, so for me, I turn off my AAD when doing turns greater than 450 degress as the initiation height will always be greater than 1200' and I wil be reaching high vertical speeds close to the activation height, I don't trust the speed setting of an aad in this situation, I want the device off or not in the rig at all. For turns of 270 degress of less, I am happy to leave it on regardless of canopy or wing loading. For info, I have used my viso to play back peak vertical speeds during the turn, the peak speed was always reached at around the 200' mark(beginning of the recovery arc) For a 270, peaks were around the 80mph For 450-630 peaks were around 115mph

I can remember the first time i ever saw 'real' swooping. It was a video of the Empuriabrava Kings of Swoop 2006. I was pretty new to skydiving and watching Jay and Jonathon fighting for first place was inspirational, I decided straight away that I would dedicate the rest of my skydiving to learning the discipline of canopy piloting in the hopes of one day being able to compete in a competition like that. Jay and Johnathon were flying the PD velocity at the time, so naturally, I decided that I would follow suit with progression through the PD product range, like many others did. My first new canopy as a result was a PD sabre 2, I also went on to purchase 1 katana, 1 velocity and 2 comp velos from new, also bought perhaps 3 second hand sabre 2s, 1 katana and another standard velo during progressive down sizes. When I started wing suiting I bought a PD spectre 120. edited to add 2 PD reserves and 1 PD optimum reserve. You are right, PD will not make any money selling the Perigrine to the skydiving public, thats not the point. They do however, need to ensure that the guys on the podium are flying PD canopies, selecting who can fly the most advantageous wing will help in doing this. PD make great products, have great customer service and the factory team have driven the standard in Canopy Piloting to where it currently is. They are however, a business. Not a charitable foundation set up so save skydivers from themselves as some people seem to think. There was no rush of 'wanna be' pilots going in when the comp velo was released, the only people who I ever saw fly then were competitive canopy pilots. I guess PD have a better strategy this time round.
-
You make it sound as if the military side of the business is some how different to the sport side. The military is just another customer, and if they didn't care for marketing and brand then they wouldn't be using the Factory Team to train their special forces guys, unless of course they have swoop comps in Iraq and Afgan. It's all business, marketing and ego, like most things. PD just do it well.
-
What's going to happen when these people want to sell their peregrine? I would assume that if you have bought rather than been given the canopy, you would be free to sell to who ever you choose? Do PD plan to buy them back? I imagine this will be the first canopy that has a higher used value than new!
-
Out of interest, what canopy was that? A new canopy I take it from a dealer? I've only bought 1 katana, 1 standard and 2 comp velos from new and the only 'check' was the order form question asking for jump numbers.
-
By that logic then, do you not think the standard velo should be subject to the same restrictions? Perhaps the market for that wing is large enough that there is some profit to be make selling that to the 'public'? I didn't compete last year but would be disappointed if the sport became more about the gear you have access to rather than the passion you put into your training. The perigee has very clear and obvious advantage in the distance event, it's not like before where the comp velo had a very slight advantage. It has the potential to create a big split in the results table.
-
In effect, PD are continuing to ensure that the guys on the podium are flying PD canopies(and now paying for the privilege), pretty easy to do in the past as the Factory Team were so far ahead of the game in competitive CP. Not so easy in the last few years as the standards have improved. I don't buy the safety angle, I've been flying very small speed wings that use a similar planform the last few years, much better low speed lift. Clever marketing, tho.

Competition Line Sets - Checks/Maintenance
matt002 replied to jacketsdb23's topic in Swooping and Canopy Control
The 6 inches or so of line directly above the riser and control lines are subject to the most amount of wear, the rds rings pass over the lines once per opening, but maybe ten times or more on the 6 inches above the riser as the slider oscillates post opening, I try to ensure I get the slider pulled down over the riser ASAP after opening. And also be careful passing the ring over the riser ring as that can scrape the inside surface of the rds ring, the out side edges can get scuffed but as they don't come into contact with the lines that should not make much difference. -
It's just common sense really, provided no copyrights are infringed then why not take a look at a proven example before staring work on your own version, much cheaper and quicker. There will no doubt be small changes made on the final design. I have a friend in the jumpsuit business, the staring point for every design will be examining a proven example first, sometimes it will be disassembled too. I liked the way NZ Aerosports released the R&D video of the prototype test jumps and different designs that eventually became the Petra. No question who put the legwork into this new generation of wing.

When I got my first x braced canopy, my average distances in nill wind went up from 80m to 95m, when I changed to a comp velo they went to 108m and that was straight out of the box, no difference in technique at all, the canopy simply had a little more. I have no reason to assume my average distances would not be greater on this new wing. I don't think that it is possible to fly your currently wing at 100% max potential all the time, a good target and sound advice, yes but achievable, no. It's just not possible even for professionals. I don't like the Formula 1 or NASCAR analogy as there are no amateur teams in either of those sports. At any world meet of canopy piloting the vast majority of competitors are not professionals, just passionate amateurs, and IMO are mostly experienced enough to fly this wing in a safe manner.
-
Well that sounds quite different to impression I got reading this http://www.performancedesigns.com/peregrine_info.asp
-
Nice marketing perhaps. I remember reading somewhere that with R&D factored in and the extra production complexity, the comp velo was effectively sold at a loss, at the last world meet I attended there were just over 100 competitors in total, so not such a big market at all. Perhaps to create perceived brand value through exclusivity is a better strategy as that perceived value applies to all the other products sold in volume. I dont believe that all the pilots who have been jumping, training and competing for years on velos, then comp velos or even JVXs are all of a sudden rendered unqualified to fly this new wing, and find the implication insulting and patronising. I have never had a problem with the factory team and other selected pilots competing on experimental wings and technology, as once the testing was completed to a high standard, it then filtered down to the rest of us. I think this new strategy by PD to create a two tier system is a real shame. I just hope the NZ Aerosports Petra is made more widely available when released, as im not in danger of winning a world championship any time soon to be having PD offer me the chance to spend my cash with them.
-
Both new, only requirement was £1800
-
So what particular characteristic does this canopy have that makes it so dangerous compared to a say a comp velo 71 that has no such restrictions? Is this any different to what PD has done for years? (Sponsor top pilots and supply them with the latest canopy/line set/rds) Judging from the serial numbers of my comp velos, I would imagine there is such a small market for these canopies that there is no money to be made selling them to the public anyway.
-
For me, the best velo wingload/wing size combination was 2.2 on a VE96, best compromise of openings, speed, harness sensitivity,glide, and low end lift in zone acc. I found the 103 slow to react to harness input, longer snivel with more 'searching' and preferred the recovery of smaller velocities.
-
I would get a second hand katana 107, and then get your first velo in a 96. The 103 is a big wing to try and throw around if your light, it's better suited for very heavy pilots. Lightly loaded, the openings are all over the place.
-
Thermals has nothing to do with it, the smoke in the video would be rising if that was the case. Also with a decent rate of 50mph+ (as this was a timed speed run) a thermal would need to be rising at approx 90mph to overcome the decent rate and produce a climb as we see in the video. http://www.youtube.com/watch?v=6Tu5Cyw8xlI&list=UUKIixYOJWw6L5FFYZe7la5Q&index=4&feature=plcp Here is another angle that shows the technique clearly, its called flaring a wingsuit, if you look closely at the ground you can see a gain in altitude and then he deploys just as the energy is spent by the climb.
-
Pretty much every canopy I've owned will max out on front risers after the first 360degrees. If you want to keep the turn going past that you will need to start adding harness input as you come up to the 270degree point. My usually turn on a velocity 84 is a 630, the risers are rock solid after the first 270, it's all harness after that point. Worth noting that harness imput is very effective on highly loaded wings, your sabre will probably need quite a bit of physical effort to keep the rotation going past 360 degrees, a sabre 2 will probaly be very slightly easier due to being tapered rather than rectangle.

It's the lower wing root that covers the handle. Its ability to cover the handle is not based on it's inflation. PS: I've flown a Phantom, Ghost, Vampire, Stealth, and Venom. Each of you stated such as fact (contradicting facts so one must be wrong). I havent flown suits with side cells running down them...but someday I will fly a V4 (hopefully!) and then I will be able to directly compare it to a suit that doesnt have the side cell (vampire 2). thanks for the info Butters I guess it must depend on pull technique then, most of my wingsuit deployments are on base jumps, I like to deploy quickly and from full flight with straight legs. The side cell is kept under tension during the pull this way and does not cover the pull (X wing and V4, I have never flown the ghost) I guess if you close the suit down at pull time with bent legs the side cell may act differently.
-
I hadn't thought of that, I will try some acro, see if that helps.
-
I have found that the suits that have a side cell running along the side of the body (most tony suits, Venom, V4) have very good access to the boc. With the side cell maintaining inflation during the pull, the wing tips tend to be held away from the boc making the pull easier than suits where the wing meets the body near to the boc, (my skydiving rig is quite small and the boc is quite high up on my back) I had a few uncomfortable pulls with my phantom where the material of the wing would get in the way and was very surprised that with so much more material, the pull was actually easier on my X wing and V4.
