  1. Yeah, and temporarily online for a few days. So, where's the dead puppy thread? Couldn't find it with the search. See, artistcalledian almost convinced me that he's badder than you. Dead puppies might fix it.
  2. Where's the dead puppy thread? I need to make up my own mind.
  3. I disagree, but, afterall, I am a BMI and therefore making big bucks in the Birdman Institute. There are few things that just, IMO, have to be told to the newbies; common sense isn't necessarily enough for people to realize these things. And, well, common sense isn't that common, anyway. Looking at my FFC cheat sheet, here are a few examples: -Deployment. While the basics of deployment are the same on all suits, there are additional considerations when flying the higher performing suits. As a matter of fact, I think if you start jumping an entry-level suit and get no feedback(ie. no BMI looking at what you're doing in the air), you might catch some bad habits that only bite you in the ass when you upgrade to a HP suit. There's no substitute for extensive ground training to get the proper pull-procedure ingrained in your brain. -Stability recovery techniques. The basic thing to do when you go into an unwanted turn, relaxing, isn't really intuitive. People want to "do stuff to fix it". Even the next thing to do, "close-all-wings-and-arch" doesn't necessarily work unless you've been trained to do it; the fact that your spin initially increases its speed when you bring in your arms and legs needs to be known and practiced on the ground. All the students I've taken up for a first flight have enjoyed it and performed well, even the ones who were at first afraid of the idea of doing a WS jump; a couple of non-WS practice jumps put their minds at ease and they were ready for the real thing. On the other hand, recently I went to do a 2-way with someone with 3 or 4 WS jumps, on a MTR3. He hadn't gone through a FFC, he just "had been told what to do". He went into a spin out the door and spent the whole jump trying to recover. He hadn't been told the first technique: "Relax". He hadn't been told how to use the "wings-in-and-arch" technique. Good thing he was jumping a large docile rental canopy instead of his own rig. The way I see it, after you add all the necessary things to the "5-minute entry-level suit briefing", you might as well do the whole thing; it doesn't take that long. I'm also a big fan of Darwin, but I don't want to act as his agent...
  4. Cameraman poking at the back of the passenger harness while the TI is gearing up the student: -"Hey, do you think that's ok?" TI: -"Yeah, it should be fine for one or two jumps more..." The way some of the passengers twist trying to take a look at their back is just priceless...
  5. Yuri, have thought about this: What about when the newbie gets a "real" suit? If he hasn't gone through a proper first flight course, he will have no idea about how to fly a restrictive suit, what to do when he goes into a spin, will be surprised when he can't reach his toggles after opening etc. Unless, of course, the newbie seeks instruction when upgrading to a higher performing suit... but... "Why should I do that? I've done 30 WS jumps in my Prodigy, I know what I'm doing!"
  6. Does anyone have experience on using soft links on tandem rigs? Someone told me that the soft links cause escessive wear on the tandem risers, any truth to this? Any other comments?
  7. Does anyone know how well the Square1 4" polycarbonate knife handles freezing conditions? I know the cheap crappy orange knifes("Z-knife", I think) get brittle when the temperature drops below freezing. I'm considering buying one of them polycarbonate knives, but I want to be sure it wont snap the first time I try to use it at -20C. I guess I could always play it safe and get the metal one, but they're so expensive...
  8. They are not. Jump Shack still apparently makes non-reinforced Type 17 risers. I've seen a few pairs recently. This article explains their reasoning.
  9. Does anyone have a line trim chart for a Minimax 7? It's an old reserve canopy by Parachutes de France. (Yes, I've also contacted the manufacturer, but I think DZcom may be faster...)
  10. Could somebody try and explain to me the logic behind Aerodyne's sizing of their various products? It just doesn't make sense to me. To give everyone a chance of understanding what I'm going on about, here are a couple of examples: My exit-weight is 86kg. For the purposes of this exercise, I'll consider myself an "Advanced" skydiver(but not better than that). That means that, according to Aerodyne's canopy selector, I should not be jumping a Smart smaller than a 150(max 89kg). Fine with me. I would be willing to go down to a 135(max 80kg), but that doesn't make a difference in the container I have to pick; an Icon I4. But now, the smallest main I can fit in my container is a 132! As an "advanced" skydiver I want to go a bit faster. Ok, let's go the other way around: I want to jump the hottest shit they have: a Vision. The 124 is about my size; max weight is 90kg. I could also be a bad boy and overload a 117(max 85kg). Both these canopies would fit into an Icon I3. But now, the reserves that fit the I3 are the 110 and the 120, both of which, according to Aerodyne, are too small for me! I can understand that when a company only makes, say, containers, it's difficult to get the sizing exactly right. But when the same company makes the containers, mains and reserves, you would think they would be able to sort their products out. I rather like the Aerodyne products otherwise, but if I can't make choices that are acceptable to the company's own sizing charts... well sorry, but I'll take my business elsewhere. Any Aerodyne people out there who would like to shed some light on this?
  11. The problem Tonto is pointing out is: 1) Open main 2) Chop main, open reserve 3) Grap grippers("damn, I just dropped my handles") to open the zippers on the arms. ...if I understood correctly. And I want my bootie snaps back.
  12. Go figure. Mine is a stock suit built after I ordered it, not an "early demo" as far as I know. No snaps.
  13. My new Firebird has no snaps for the booties either. Apparently the new way of thinking at BM headquarters is "the leg wing will trail between your legs and will not get in way during landing". That's from the latest BMI manual. Personally, I want my snaps back. Landing might work fine, but what about walking back from the landing area? Walking to the plane? My current solution is to open one of the front zippers and stuff the booties inside the suit. I'll install a couple of snaps as soon as I get access to the tools needed. I have no ideas for the missing thumb loops or the LQRS cable, sorry.
  14. Well, you'll need to stop by when I'm in Australia as that's the only place my rigging licence is valid in... But any rigger should be able to build you a new bag and to open the corner seams a bit.
  15. Ok, better late than never; here are some pictures. The blue rig is an unmodified Legend 00, the black and yellow one is my modified Legend 00. Mine has a Hurricane 135 in it, the blue one has a Katana 120. IMG_2039s and IMG_2040s are close-ups of the open containers, IMG_2039s shows the modified container and IMG_2040s the original one. IMG_2047s shows how the bag sits "grommet-to-pin" in both rigs. My bag lays flat filling the whole container unlike the original bag in the blue rig. IMG_2048s shows the rigs closed "grommet-to-pin" the blue rig has an ugly bulge on it. The picture does it no justice. IMG_2037s shows the effect of the opened corners.
  16. That's quite simply not true. From my personal point of view, I've known two skydivers who died in traffic accidents. I've known many more who died skydiving. Both of those two died while riding something on two wheels. One of them in Bangkok. Your average trip to the DZ is no where near as dangerous as throwing yourself at the planet. Repeatedly.
  17. I'm quite impressed with the Firebird myself. Still as easy to fly as my GTi but you can get SO much more performance out of it. I did a FFC with three people on it, and two of those were too big to fit my GTi so they jumped the Firebird. Both nailed the body position and I nearly got out-flown by a first flight student. Twice. Of course that could just be me and my sucky flying... The few jumps I've done with the suit left me with the impression of an easy suit when not flown to the max. Once you pick up the wing tip grippers and kick the suit into gear, the performance(and the pressure on your arms) goes WAY up. I did some back-flying at the end of an 8-way flock and the suit is really easy to fly on it's back, much easier than my GTi. The wings really pressurize and there's really a lot of pressure on your arms(damn, another set of muscles to train). We did another flock with me flying as the base on my back, and we did well over 2 minutes from 15K. Next I'm going to see what kind of performance I get when flying solo and maxed out the whole jump. I short, it's a great suit(but I haven't flown anything than Classics and GTi's so far)
  18. I did indeed have plenty of control samples. With and without contaminants, in the sun and out of the sun. Of course none of that mattered since all the samples were of identical strength after the exposure. Better luck next time...
  19. When DEET melts plastic, it tends to do so immediately. This doesn't seem to happen when DEET is applied to ZP nylon. Of course its always better to err on the side of caution. However: I have done an experiment with DEET and ZP nylon. Basically I took some brand new ZP, cut it to pieces (75mm x 125mm), stuck the pieces on a piece of board, applied different contaminants(including DEET) and kept the board in the sun for about 50 hours during a two month period. Afterwards I tested all the pieces to destruction. None of the samples had degraded in strength. The reason for that is probably the fairly short time that I had for the experiment. Also the new ZP had a flawless coating on it; I had trouble getting some of the contaminants to stick on the samples! Because of that I believe that the contaminants never actually got in contact with the nylon. I intend to repeat the experiment with used fabric that has lost some of its coating. Also I plan to wait longer the next time. I don't know when I have the time to do it, but I'll post the results here when I do.
  20. Yes. Altitude, forward speed and vertical speed readouts work fine. Glide ratio stays blank for some reason; I think the glide ratio just isn't good enough for the unit to consider it gliding...
  21. Of course the Forerunner series units don' t have altimeters in them. I've been using a Geko301 with good results. I used to have it on a chest mount pillow, and surprisingly had excellent reception. I have just built a really nice(if I say so myself) helmet mount for it. Maybe I'll even manage to get pictures(don't hold your breath, I'm still looking for the pictures I took of my ws-modified Atom Legend...)
  22. Nice! Did you have it custom made or can you order those from somewhere? Mine is really just the original bag with the dimensions rotated 90 degrees. That makes packing slightly more difficult; especially the non-locking stows on the side of the bag don't work too well. I am planning to move them on the closing flap as soon as I find a sewing machine and the time to do it. Also the bag is VERY shallow(as in "not very tall"); bagging the canopy on my bag requires a somewhat different technique. I've thought about making the next version the same as the original bag, except that the grommet and bridle would be in a different place, 90 degrees off the original location. That would cause the bridle to pull in a very strange direction though(see attachment). I'm going to try it("as soon as I find the time and a sewing machine") and expect some funky openings. Or it might work just fine. We'll see.
  23. I'll see if I can get some photos later this week. Just think about a normal bag being packed grommet to pin. You'll notice that the bag is too tall for the container. Then, without rotating anything, just make the bag shorter and wider, so that it occupies the same space as the original bag. I'll see if I can get some photos later this week. The exact length is "slighly longer than the original". I wouldn't worry about it too much, I think the original bridle is long enough. Yeah, maybe. Probably. I don't know.
  24. Good thing I didn't ask them before I replaced my reverse risers with Miniforce...
