    I think you are referring to the "Double Joker Reverse". This used to be a compulsory block in the FAI/IPC freefly divepool. Many competitors found that one very hard. The FAI/IPC removed it from the divepool in 2004. Today it is still classified as "very difficult" in the addendum C of the freefly competition rules (http://www.fai.org/parachuting/system/files/artistic_adc_2007.pdf) Considering what you said about the lack of advanced freeflying talent on your new DZ, I doubt this move is the logical next step, but the technique is this: the sitflyer should initiate and drive forward really well (not easy when docked). The headdowner should do a backflip transition in place (without backsliding, as that would make the sitflyer's job more difficult). As always, eye-contact is crucial. You might want to look at http://home.scarlet.be/vertigofreeflyteam/freefly_divepool_2005.pdf for a list of other moves to try. Mike

    How does this Velocity on steroids relate to the competition canopies the PDFT guys are jumping?
  3. breadhead
    It's all on the FAI website: http://www.fai.org/parachuting/node/349

    Hardly. It depends on the uppers and the lowers themselves, not as much on the difference between them. The transitional effect you describe certainly exists, but it lasts only "seconds". The hat falls "minutes" from 14kft. The overall effect of the transition between wind layers will be much smaller than the inherent margin of error. No way. For all practical purposes: if it falls slower, it will drift further. (For the experts wanting to split hairs: I can imagine an artificial experiment that would reverse this logic. However, such an experiment would have no practical relationship to the hat&skydiver-scenario. It would require the slow-falling object have (1) virtually zero drag in the horizontal direction while having (2) a large enough mass/inertia).

    Yes. Correct. I will be further down the wind line than where you deployed. No discussion there. The only point of discussion is: how much further? All the input-parameters are very inaccurate: - The fallrate of the hat: 10fps? 20fps? 30fps? - The windspeed: 30kts at 15000ft, but what about winds at 7000ft? - The winddirection: different directions at different altitudes You are looking at a search area of several square miles. Short answer: forget about it. The good news is: L&B are the best. Send them an email, tell them your story. You will be surprised by their reaction. Mike

    Yeah! http://www.babylon-freefly.com/GalleryPages/Record-015.htm Thanks to all, it rocked! Mikie

    By that rational, it would be impossible for anyone doing a 270° to fly a left pattern. Either they would do right turns in the beginning of the pattern, followed by a left turn at the end. Or vice versa.
  9. breadhead
    It all depends what your definition of pattern is: (A) Pattern = thin line. (B) Pattern = wide corridor. Both definitions are very useful. - Definition (A) is useful for accuracy, for swooping, etc. It defines the pattern based on exact altitudes and precise checkpoints along the way. This is the competitor's definition of a pattern. - Definition (B) is useful for traffic-management. It defines the pattern based on approach directions, no-fly zones, etc. This is the DZO's definition of a pattern. I believe that in this thread we need to use definition . Definition (A) is useless for the topic being discussed. A student may do his last 90° left turn at 1000ft. A more experienced jumper may do his last 90° left turn at 300ft. And somebody else may do a right 270° around 700ft. From the point-of-view of traffic management, all three of them are following the same pattern.
  10. breadhead
    He is correct. His pattern was a right hand pattern, with a left hand turn at the end.

    If you speak French, here it is: http://www.ecole-speedriding.com/ They go pretty high on wingloading because they want to stay as close as possible to the slope. I was surprised to learn that the goal for "speedriding" is not to fly as high/long as possible, but rather to "attack" the slope as much as possible. They gave me an overloaded Springo 110 (@ 1.8), even though they had plenty of larger canopies available. They were willing to let me use my Velocity @ 2.2 as well (which I didn't, it was still brand new then).

    I have, in winter 2006, in that very location you see in the video. The guys you see in the video are skiiing & paragliding instructors. They have a small school to teach this stuff to beginners. They are using regular skydiving canopies between 90 sq ft and 160 sq ft. If you're a reasonable skier, it's not technically difficult at all, but I would definitely recommend getting instruction the first couple of times.
  13. breadhead
    Yeah, 270's are pure evil. Better to do a 450 in that case.

    Installing/uninstalling RDS every few weeks ...

    So: -1- HPL's require a separate landing area or a separate pass (proposals above). -2- A separate landing area and separate passes are not economically viable (see Brian Burke's post). Adding [1] and [2] together leaves a very bitter taste in my mouth.
  16. breadhead
    If you hang in deep brakes after a cutaway, you land about the same time as your freebag and slightly before your main. This suggests a cutaway main descends about as fast as a canopy in brakes. Having flown around other people's cutaway mains a few times confirms this. If you need a number, I would say 10-15 feet per second, but the variation is probably quite wide.

    While the Neptune is a great device (I own 2 of them myself), I have found the speed readings to be very unreliable.
  18. breadhead
    FWIW: me too
  19. breadhead
    Nice work. Can you share the speed information too, for the canopies you mentioned above?
  20. breadhead
    organizing a national swoop tour according to FAI rules, but without reading those FAI rules first ... priceless
  21. breadhead
    For what it's worth: I did exactly the same with a JVX 90 and a Velocity 90, and came to the same conclusions.
  22. breadhead
    I remember the guy with A-40,000 got mentioned in the Parachutist a few years ago, with a picture, a little bit of text about him, and the title "A40K". If you are that guy, and if you read this ... you said you were going to develop a packing machine. Any news on that yet?
  23. breadhead
    Mine too.
  24. breadhead
    They call it "speedriding".
