    Nice guideline Davelepka, For the first generation FreeFlyers is the sitfly possition the safety position but for this generation a HD possition can be as well a safety possition. Both are for me basic body possitions. A FreeFly Gypsy

    It create an very thin layer turbulance where the air has less resistance. The surface, the roof of a canopy, is perhaps not big enough to make a lot of differance but maybe it is something for the birdman. The speeds are higer and so as well the effect perhaps. A FreeFly Gypsy

    I did read the program, it is a good program what points out how to master your canopy and land safe, but again, there is no word about basic aerodynamics what is for me as well important. Points like: -Why we stay in the air? -What does happen when we make the canopy asymetrical? -Why we need presure in the canopy, -What does happen with a riserturn and what with a toggle turn, -.... Those things are said during the first jump course but during canopy progression often forgotten to say. Give this info during canopy progression and it will help the pilot to anticipate on things. The discusion here proves that is is forgotten or at least not tought about. A FreeFly Gypsy

    You are right, but, I do not hear anything about the basic aerodynamic knowledge. the same kind of canopy with a different wl will perform not the same. Every canopy has his own characteristics and recovery arc. That makes it difficult to judge. A low wl (less than 1.2), not much presure in the cells, makes it that you do not win any lift with a 180 or a 270. The straight aproach will give the canopy his best shape to land. A FreeFly Gypsy

    is the article somewhere at the web? A FreeFly Gypsy

    Probily he is and I should not give a damn. I think I was to pissed off the moment I wrote the comment. thx anyway, A FreeFly Gypsy

    For me he sucks but I have to be carefull because I'm now with a prejudice mind. He's way to conservative and all things what he think is good is the only way. The question is in fact, can you outrank somebody when you have more jumps but less funjumps than the other person? What value is there in workjumps? (on the matter canopy flying). A FreeFly Gypsy
  8. Bartje
    What are funjumps,.. I was in a discussion and somebody asked me how many jumps I had. I said 1500 funjumps and perhaps 150 workjumps. He had over 6000 jumps with 5000 workjumps (tandem). What value can you give such man when he's start talking about canopy flying? He is less years in he sport then me and never jumped higher than 1.9wl. For shure he can learn me something about tandem canopy flying but what with his other canopy skills. He is jumping a stil.120 and he pull rank on me when I start giving information at somebody. Any idea's somebody? A FreeFly Gypsy

    Birdlime, or birdglue, is a glue what stays flexible when it is dry. If you make a new canopy than I will not use fabrics but plastics. In the past I saw competition swimmers with a suit where the fabric was not always at the same direction maded. It looked as stripes. The advantage was that the water was less turbulent when it passed over the body. Is that not an idea for a canopy. A fabric that made so the airflow is less turbulent? A FreeFly Gypsy

    I think it is ready, last summer at Spa the Paratec FreeFly team was training and they are jumping the Rage. They told it would be rready by the end of 2004 but I did not hear anything yet. Perhaps it is like you said, very difficult to build. I'm going to look for more news. A FreeFly Gypsy

    Perhaps my english is no that good in technical terms but is this not the combination what you mean? http://p4961.typo3server.info/fileadmin/user/pdfs/The_Rage_Principle_A4.pdf A FreeFly Gypsy
  13. Bartje
    Still the Rage sounds like that. Closed nose; high pressure airlocks, nose down (closed, just open in front, just after the nose) A FreeFly Gypsy

    I'm talking with my (little)experience. when I did fly a Velocity at 2.45 it was loosing performance. The Fx did loose performance from 2.25. After those wl it was only more speed and not more lift. the Xaos did loose performance at 2.65.(but fast as hell) Im not saying that I'm a big time swooper but I like the speed in my landings. A FreeFly Gypsy
  15. Bartje
    I just want to say that after a wl 2.4 with a velocity you loose performance. indead the pd boy's like timmy has a wl 2.1. If he need more speed they take extra weight he told. I'm into the speed and speed carve. A FreeFly Gypsy
  16. Bartje
    My Fx89 did had less lift than my Velocity79. You are not winning performance, you are going to loose performance with the Fx85. Openings from a Velocity are much better as well. A Fx has his maximum (sorry for the correction) wl at 2.2 as a Velocity has it at 2.4. I think you are better with a Velocity with 2.2 wl than a Fx with 2.2 wl. A FreeFly Gypsy

    the 435 was during the dutch Swoop Tour at Stadtlohn (Germany) There seem to be problems with the record to be official but it was with an electronic eye an laser distance mesurement I belive. more info at: http://www.euroswooop.com/dutch/2004/IndexResults.htm It is in meters. Like you said, not on a regular basis. A FreeFly Gypsy

    Is Icarus not testing a 33cell cross braced canopy? I heared something like that in spain that they are jumping it but yet the canopy has some minus points. A FreeFly Gypsy
  19. Bartje
    I do think there is a next generation. The German canopy, the "Rage", with a closed nose in front and the next one will be cross braced. The test I did see was unbeliveble. A lot of speed and lot of lift. The non cross braced was already faster in speed than the Vx or Velocity but the lift was not great for the speed. The first year there was a Rage at the podium in a German swoop competition. The Rage, the new Icarus, the Xaos27, I think we do not have to wait 7 a 10 years. Here is a link with more info from the Rage: http://www.paratec.de/index_start.html A FreeFly Gypsy

    my apologies, I took the wrong conclusion. What do we do during the time? I'm not 100% happy with the current general situation. During my travels I did see one solution in France. The drops vary with the windspeed. With much wind the slow freefallers go out first, with less or no wind the slow freefallers go last. This does help the separation but is not that easy as guideline. I have to say they operate two pilatus porters and not one big airplane. As you say at skydive AZ they have two seperated dropaxes, is does help the traffic spreading. A FreeFly Gypsy
  21. Bartje
    the goal is not doing or not doing your swoop, the goal is spread traffic. As I understand your are happy with the curent situation, I do think we have to rethink a lot on safety matters and spreading traffic is one for me. Spreading traffic is a way to make thing safer and my question is how to do it. I do travel a lot, been to boogies an jumped lots of airplanes. (we are called the FreeFlyGypsies you know). It is just the lac of discipline what worries me. At boogies or big dropzones there is more discipline than on smaller dz's but with the current evolution there is a problem. A FreeFly Gypsy

    When there is a group smaller than the 4 way with 2 fast canopies in it I think it is a good idea to let them go before.Especially when there is a big airplane like a twin otter. The problem does not lie only in the exit of the aircraft I think. The more people there are the more you have to anticipate the others and increase the chance for problems. On my homezone they do well I think. It is just that I see so many stupid things everywhere. How to prevent traffic over the dropzone as I see it: -Until now the ideal would be, when you jump a big airplane, to do 2 jumpruns. One run for the fast freefallers and one jumprun for the slow freefallers. First run the biggest group so the smallest group jump in second run before tandems, AFF and high pullers and wing suit flyers. -A dropzone with more than one landingzone with a left patern.

    It was a piece of the "hand deploy" test in the day's when I started skydiving and switched from "ripcord" to "hand deploy". A FreeFly Gypsy
  24. Bartje
    When I started skydiving that was part of the first jump course. Left circuit,the canopy below you has priority, not playing with your canopy lower than 1000ft and always be aware for other canopies. The problem is stil out there, the versitality in canopies is to big now for all to land on the same spot and create more than one landingarea only move the problem. Skydivers start flying across eachother at an other altitude. I think we have to change our idea about exit the airplane in terms of canopies. One way to do it is to look with what kind of canopy the majority jumps in what group and start from there. An other thing I did hear from the chief instructer at my HomeZone is when you make a rule, keep it as simple as possible but a simple rule does not cover all. A FreeFly Gypsy
  25. Bartje
    Point taken. The problem is not pointed to one kind of freefalling. The problem is that there are too many canopies at the same place at the same moment if you do Swooping or not. I did get an pm and I do think he operates an airplane or is a airplane owner. He said that skydivers are not ready to pay any dollars more for a jump? One of not that many sollutions is 2 jumpruns. One run for fast fallers and one for Slow fallers. It is not the most ideal sollution but I did not hear yet an other one. We have to rethink our way of operating when we want to keep it safe. It is the skydiver choise for jumping or not jumping but this year it was for the first time that I did not jump on a dz because I had some safety issues. A FreeFly Gypsy
