    "Slipping out of the harness"??

    The harnesses are not perfectly inescapable. The leg straps (and the rest of the harness) on most or all current designs don't prevent the wearer from lifting his or her legs far enough that the harness no longer supports the wearer in a way that makes the harness want to stay on. (I.e. in this case, the user can slide butt-first out of the entire harness. This is verifiable on the ground for some people.) The yoke design will not guarantee that a head-down deployment won't strip the rig off the wearer. I don't know how tandem student harnesses work well enough to talk about them. Sometimes harnesses fail (webbing breaks or disconnects), too, although I haven't heard of that resulting in harness escape as much as just spinning into a hard landing. All of this is rare, from what I understand.

    Is that good deal?

    See how much you could put this rig together for yourself using new parts. Then look at other used rigs that would provide you comparable quality and/or utility. Then see how you feel about the price. Because "fair" is just whatever the buyer and seller agree it is.

    toggles in or out?

    Did his invective include any explanation why you must not do it the way you were doing? And, where do you mean "placed"? Do you mean toggles relative to the risers when you set the toggles in the brake line eyelets near the start of packing? Or do you mean when you set the risers on the outside of the reserve container as you place the d-bag in the main container near the end of packing?

    Stalling

    You should, or even "must" ask your instructors for help on these things. They can watch your landings as they happen and tell you how to flare better. We can tell you that if you can't stall a canopy by pulling the toggles to full arm extension and holding them there, you can "take a wrap" on the steering lines - move your hands in a little circle while still holding the toggles so the steering line passes once entirely around your hand, effectively shortening the steering line by several inches. Then when you pull your arms to full extension, you'll be pulling several inches further on the brakes. You'll want to ask your instructors to explain what you need to be aware could go wrong when you do this; many of us know and consider it "no big deal" but young students usually have no more knowledge of these important details than what their instructors tell them. The instructor(s) is/are there to tell you what you need to know, when you need to know it, and to try and keep you as safe as possible based on how you're progressing and what you need to learn next. Even if it's not as gratifying as posting online and reading.

    Infinity wrinkles

    KellyF knows more than I do about this, but... I'm pretty sure wrinkles on Infinitys at that flap point are a packing issue - the main bag not being filled and shaped wide enough, or something like that. Two of my Infinitys have wrinkles on the left side right now - clearly _that_ is a packing error on my part.

    Skybadivin'

    There are really only two problems with jumping in the rain: 1. rain clouds are generally very low clouds, at least where I live. Only occasionally through the Summer is this rule excepted. 2. skydivers are wussies in a lot of ways that, summed up, make most of them not want to jump in the rain. Gear gets wet, canopies have to be dried after the last jump of the day, clothes get wet, it's dark and gloomy, and the air stings. For some reason this puts jumpers off. (It doesn't seem to bother the pilots, though; they're pretty buff. )

    Remote cameras

    If you're talking about wired-to-deck cameras, I have this to say: [url http://www.monkeykam.tv]MonkeyKam[/url] used to sell lipstick camera parts and kits for connecting to and using regular digital video cameras as tape decks, but I don't see that stuff on their site anymore. I found [url http://www.jonescam.tv/productInfo.php?pid=56&pname=JonesCAM+Helmet+Camera+Kit+%28480EX+Kit%29]this[/url] in a previous post. Basically you can get a camera lens and CCD that takes power and provides some sort of signal in a small package with one or two long wires, stick this on your helmet or wherever you really feel it needs to go, then plug the wires into a digital video camera that can take an external input. One problem is that my old Sony PC-1 doesn't take external video input. Another problem is that video shake reduction can be done digitally in the deck and mechanically in the lens/CCD assembly. I'm not a paid pimp for Sony when I say I understand their digital camcorders do both. Having a camera just do it digitally reduces image clarity/quality/resolution (when there are shakes that get digitally removed). I presume using a remote head on a Sony camera would eliminate the advantage of the mechanical vibration damping because the remote head wouldn't have those components. But on any other camera that doesn't have mechanical damping anyway, it shouldn't make a difference. If you're talking about wireless cameras, then basically they take one of those "spy cameras" you see in all the X10 camera ads (that aren't as prevalent on the Internet as they once were, thank goodness) and they slap a battery pack on it. The X10 denomination has next to nothing to do with the camera (but it sound sexy); these cameras broadcast the video by radio to a receiver, as you say you heard.
  9. In my single-digits I was scared of the door. (Scared of heights, really; this is why I did static line. ) When it opened I would actually put my hand in front and below my face so I couldn't see out and down and freak out before it was time for me to start climbing. -=-=- So one jump my instructor says he doesn't want me being scared of sitting in the door right before I climb out. I get the point that he thinks I need to show a little more bravery. So when it's time, I sit in the door, then I lean out, climb out, look up arch and go. Back on the ground, my instructor says that was good, but from now on I need to wait for him to tell me it's time to climb out; we hadn't reached the spot yet at that point. I guess the winds went easy on me. On the next jump he made good and sure to put his arm in front of me in the door. -=-=- I'm not going to go into details about the time, as a student, I tried to tell the pilot how to fly better (smoother). I quickly learned that if I don't like how the plane's flying, it's because I'm a sissy scaredycat skydiver and my job (barring exceptional circumstances) is to shut up, hold on, and then get out. Thankfully this pilot will still fly me. -=-=- Once when I was on solo status, my ability to spot earned me the privilege of leading a group of solo students exiting at 13,000 feet when uppers were 50 knots. I did my calculations and determined where I should go so the spot was as good as possible for everyone. My answer was right over this one island in the river. I told the pilot on the ground this was the spot I wanted and asked if he could start jump run there, and he said he could. (He was/is a talented jump pilot, even if people say his pattern manners could use some polishing.) No problems until I get a little nervous before boarding and convince some very experienced RW guys to go with me to check the spot. Well, they need to get out right before me because they open lower and load their canopies way higher, and I didn't tell the pilot that, figuring the pilot would probably turn onto jump run several hundred feet before the exact point I indicated anyway... So we're at 13,000 feet, the plane dumps the load for the first landing area, then the pilot makes three beefy turns and cuts the power again and I look out and... we're at exactly the point I told the pilot about. So, I have to tell the pilot (at 13,000 feet, with the door open, with people who are supposed to be getting the heck out of his airplane but are not) that I actually need that same exact jump run over again, but started 1/8 mile earlier because of the extra people I sort of put on the load and didn't tell him about. Thankfully I knew the trick of laying sideways on the floor so I don't have to hold up my student rig in a 2 gravity "pissed-off pilot" go-around.

    what causes this

    The most important purpose of most newspapers is to sell advertising. That is my explanation for almost everything I see, right or wrong, in newspapers. The same applies to television news and many television channels, of course.

    Tips on Spectre landings?

    Can you recall what your instructors told you about finding the stall point on a canopy, and doing practice flares? Have your instructors talked to you at all about the possible differences in landing a 7-cell canopy vs. a 9-cell canopy (I think the Navigator is a 9-cell...)?

    falcon and tempo.

    Well, very few of us still jump F-111 mains. Our reasoning is that we like ZP mains, a lot. By the way, how much do you weigh? Finding a good deal on a used just-off-student-status type canopy can take a while, so patience may work out for you here. People have written previously about how they like or do not like the Tempo reserve. I will confine my response to say that I have not deployed one but I am OK with having it be my last chance canopy until I pay the extra money to upgrade to a PD Reserve. (One of my rigs has a PDR, one has a Tempo, and the third is "between reserves" right now.)

    new canopy

    I think the consensus is he's just a great guy all around. (P.S. Thanks for coming to my house party!
  14. When I first buy a new canopy, I'm thinking all black with black lines. (I'll go Dacron if I have to.) Someone at my DZ has an all-black canopy and I love seeing that thing.
  15. For my own information (because I've been following the Rocket-EZ a bit) what was the distance of that hop? And, the problem with the rocket-EZ is there's no room for a single passenger, let alone skydivers, with gear, plural. Apparently there's these big ol' rocket engines / fuel tanks in the way.

    Vector 3 M series vs. Racer 2K3

    It is my opinion that no regular reserve deployment compares in speed (or vertical distance) to a skyhook deployment from an inflated canopy. Everything else (pulling the reserve handle, having the reserve ripcord / pin pulled, or having the loop cut) just gets the reserve container open so the PC can eject, and then it takes airspeed and time to yank on the reserve PC and go through the steps of deployment to line-stretch and bag removal. The skyhook should (when cutting away from an inflated canopy) get to that point in about the vertical distance of all the webbing involved. Riggers vary. I am always concerned about what my riggers know and I make sure each is competent for my equipment. If a riggger isn't, he (or she) drops out of my rigger pool. Pop-tops, when packed properly, typically suck down into the reserve container area pretty well. I don't know about Racers specifically. However, people who worry about lines going over their backs do voice concerns about having pop-tops. I don't know if their concerns have any incidental or statistical backing, but line-container entanglements seem like they would be "as bad as anything could possibly get" so I can see why people would want to be overly cautious about this.

    Jumping a low WL HP canopy

    I'm considering doing this - jumping a high-performance canopy shape at a low wingloading - because I have started to like light wingloadings for neutral flight speed and final landing speed, but i want a canopy that can be made to dive more / fly with front risers more. The wingloading I expect to try out some higher-performance canopies at is 1.0 to 1.15 pounds per square foot. I will of course not go under the manufacturer absolute minimum weight for a canopy. But barring violating absolute minimum weight, I also am curious what the dangers could be of light loading. I reckon the primary danger I'm looking at is not wingloading, it's the shape of the canopy - the more responsive any canopy, the more skill and training it takes to fly it safely. And all the control inputs and outputs will change drastically compared to tamer shapes.

    FreeFly Suit

    Crayola has some stuff...
  20. * You could inflate the canopy at a specified loading-speed in a wind tunnel (i.e. at the speed it would glide with either brakes set or full flight with a specific weight under it) and find the area of its true shadow. * You could do the same wind-tunnel thing and identify the left or right angle from vertical of the normal vector of the topskin at every point, and use the cosine of this value as a "lift factor"; multiply the lift factor by every area of the actual topskin size. This would attempt to address canopies with more "cell bulge" flying smaller than canopies with more rigid shapes. Of course, not every part of the chord from nose to tail produces lift at all, so this measurement method still contains misleading assumptions when producing a size number. (Specifically, it assumes that a 150 sq ft canopy has 150 sq ft of topskin or effective topskin that is producing lift.)

    Screwed with my Diablo 170?

    How do things look from the company's point of view? How much should a full cell replacement cost? Are you saying you think you should get that cell replaced under warranty? This sounds like a friend of mine who purchased two new motorcycles in three years and each time within 500 miles he got a lucky nail in the rear tire. The warranties said "tires get nails sometimes. When they do, that's your problem." Canopies open hard sometimes and their cells rip open. It's hard to decide why, and therefore whether it's a manufacturing or material defect vs. user error (even unknowable error) or bad luck. They can support their product but however they do it's going to cost them. How much should it cost them, and how much should it cost you?

    tert canopy jump method question

    "Safe" is, of course, relative. Some people hold their own tert-canopy in front of them in a bag of some sort and exit the plane back-to-the-wind and toss it away. Of course, I usually hear of them doing this for cutaway jumps, so I don't know how "safe" you would call that.

    Question About Pricing

    There is an online calculator somewhere that can estimate the market value of the Cypres for you. You should be able to search the forum for it. I would estimate the Dolphin D2 9/96 VG condition at whatever similar containers in the classifieds have been listed at previously, minus any incentive you want to give for quicker selling, etc..

    Acceptable Loses?

    Humans are inherently fallible. This is something we have to fight against with preparation and training and so forth. An example of preparation is having a set landing direction for a load. But humans also have egos and are fun- or thrill-seeking. Skydivers especially. This can work against preparation and training sometimes. I don't think we can ever get skydiver perfection. We can perform planned stunts that will cause less or more risk and individual jumpers can act in ways that are less or more careful on each jump. Is it possible to draw a line? And if so, where would we draw it?
  25. Someone recently posted that there are no "hard limit" answers in skydiving questions. This would be one of those places.
