  1. Thats why I still think its (warm as it may be) a good idea to always have the legwing zipped up when entering an airplane. Sure it may be a bit warm in some countries, but it prevents a lot of scuffling about and potential dislodging of pins and pilotchutes as well if one just has the legs done up already (plus less annoying of other jumpers in the load by pushing/moving around). Zipping up in the air...not sure thats the best advice ever. If you have more altitude in case of an emergency, pull higher. JC FlyLikeBrick I'm an Athlete?
  2. Regardless of procedures...Id prefer never to exit with a legwing or armwing not zipped up. Even on a hop and pop at low altitude, a loose armwing/legwing would add a lot of dangers. The flapping fabric can inflate asymmetrically and both legwing flapping up and armwings flapping in front could occlude handles for main and/or cutaway/reserve. JC FlyLikeBrick I'm an Athlete?
  3. You mention wanting to fly a PF Ghost, but unless you're a heavy person the Phantom3 will most likely suit all your needs in flocking, acrobatics and performance flying. JC FlyLikeBrick I'm an Athlete?
  4. I'd also say AAD on both jumpers mandatory. The changes of two people smashing into eachother hard due to a messed up exit are quite realistic. As are the chances of other people on the jump getting hit by the wingsuiter or rider at the time someone falls/jumps of. Pull-offs, I would only do those (if you do them) with more experienced skydivers, as hesitations and pilotchutes in burbles create a whole other arena of intersting situations for rider and pilot that a newby jumper with 80 to 100 skydives probably doesnt need to be in at that experience level.

  5. The grippers are designed in such a way that you can position the hand on them in various ways. Holding the grippers with the last 2 fingers, hooking a thumb behind them, or simply holding them with the whole hand. The grippers are mostly used in the 80>100% flight range to finetune the direction/angle of the wing. Try not to use them to pull on the wing, or as airbrakes during normal flying as that leads to less stable flying due to to much tension. Fly a smooth and airodynamic shape with your body, and ignore the elbow joint. only hinge at the shoulder, and treat the whole wing as a door. With all flat being 100% and all back (still straight) being 0%. This gives you the most fine controls over you flight. JC FlyLikeBrick I'm an Athlete?
  6. I just finished editing a new team video, showing Benoit and myself putting the new PF Havok through its paces, with our new cameraman Patrick Wake filming us! Shot on Texel (Netherlands) during training, and Siofok (Hungary) during the competition. Check it out on www.vimeo.com JC FlyLikeBrick I'm an Athlete?
  7. Helmets that snag lines and break your neck on opening sound like a bad idea. For most people the 1% decrease in drag will result in a smaller performance gain than a good 100 or more jumps of training will give you. JC FlyLikeBrick I'm an Athlete?
  8. Minimize drag by 1% so a 6th GoPro can be added on a 5ft extention pole JC FlyLikeBrick I'm an Athlete?
  9. Dimples on golfballs work with the speed/size/weight of a golfball. How many airplane nose-cones look like golfballs? JC FlyLikeBrick I'm an Athlete?
  10. Fear that we make the same baby steps/progression as other disciplines instead of skipping straight to 400 ways in a few years JC FlyLikeBrick I'm an Athlete?

    Big suits

    Thats mostly related to wing thickness. Alien suits also has an internal bladder thats difficult to depressurize. But pressure in most suits is just over 1 atmosphere. Thicker wings just feel more rigid. Again, compare it to thin/thick inflatable beds. Cell pressure is the same, stiffness varries quite a bit. JC FlyLikeBrick I'm an Athlete?
  12. Will structured and diciplined training of an AFF student create a better skydiver down the line, as opposed to a person given a parachute and a few youtube videos. Its the seeds planted now that determine what we will grow into over the next few years. JC FlyLikeBrick I'm an Athlete?
  13. Thats exactly what I was stating as well. Not questioning anyone's decision. Merely stating a few good reasons. JC FlyLikeBrick I'm an Athlete?
  14. option 1: UK rules option 2: Not being in a rush and wanting to be competent skydiver before adding a wingsuit in the mix. Both are great reasons to wait untill 500 jumps or more...of all good reasons to start wingsuit or any other dicipline or sport, rush is the worst one.. JC FlyLikeBrick I'm an Athlete?

    Big suits

    Airlocks by themselves dont make wings harder or softer. Nor are they a new thing. Its essentially a vent. They've been used on wingsuits as early back as the Acro, Birdman Blade, Firebird etc. Its simply a bit of fabric that closes of when air wants to come out. These airlocks serve a function when the wing is inverted (keeping the air in) and thus are often found on suits that are made for aerobatics. But in full flight, air is always streaming into the wing. So regardless of locking/design, there is no working airlock during flight. Its simply an open vent when air is flowing. The advantage of an airlocked chamber is that temporary loss of pressurization is prevented when there isnt airflow. The downside that can happen with airlocks, is that inflation is hindered in the first few seconds due to the vent being very small. But in general, the wing holding pressure is also seen mostly by volume of air inside the wing. A very thin/flat wing like the P2/P3 will bleed of the air quicker than the thicker/bigger wing of a Ghost3. Both have the exact same cell pressure. But the thicker wings of the Ghost3 often have people talking about 'the higher cell pressure' and 'better airlocks'. But seeing as the vent is open when air is flowing in, the only time airlocks really do their job on a suit flown on the belly is when we try and push the air out at pulltime/try to collapse wings. Just look at side profiles of different wingsuit/designs built for either agility or distance, and you'l see sleek/thin lines (low drag) on suits made for agility and thicker profiles on suits built for stamina/distance. On ZeroP vs Parapak: Zero P holds air a bit better (parapak is slightly more leaking in terms of keeping the air inside, but its not a big difference) Parapak has a bit more drag (rougher structure) ZeroP is a bit lighter (saves several 100 grams on bigger suits). The extreme are suits made from a special Cameroon ZeroP fabric. They are noticably lighter and more slick compared to other suits. JC FlyLikeBrick I'm an Athlete?
  16. Its going to be a great week! I'll try and keep people posted on the results as the events unfold! We may have one team not coming due to a speedlfying injury, and we may have one or two extra local teams. But here is the team listing for the Artistic Competition.

    Big suits

    Cell pressure doesn't differ much from one suit to another on modern wingsuits. The biggest difference between a harder and softer wing is how thick the actual wing is. Similar to inflatable beds, a bed of only a few cm thick with 1 atmosphere of pressure inside will be easier to bend/fold than an inflatable matras thats 50 cm thick. The thicker wing profile takes a lot of strain of the arm, but at the same times makes the wingsuit behave more like one surface (which in some of the bigger suits can lead to instability) also due to interconnected surfaces (leg input influencing arm-input and vice-versa). One isn't necessarily better than the other. But its more what the pilot prefers. Different manufacturers design towards different goals in terms of flying. JC FlyLikeBrick I'm an Athlete?

    Big suits

    In my experience, suits that have a bit lower cell-pressure allow for easier pull/collapse of the armwings. Perhaps a bit more fatigue, but a lot mor agility and ease of flight in return. JC FlyLikeBrick I'm an Athlete?

    Big suits

    The longer cell allong the body (usually combined with a longer gripper as well) is the part that one needs to grab around to avoid grabbing fabric. It complicates the pull on all bigger suits instead of making it easier. With a good pull technique one can learn to pull without grabbing fabric easily, but on smaller suits this usually is no issue. JC FlyLikeBrick I'm an Athlete?
  20. Its "Can't we all get along" The word "Just" is an incorrect addition. That aside, if anyone on a DZ doesnt like the discipline, jumps, judging or any other aspect and chooses to jump with others, elsewhere or sit a dive out thats just choosing to do what they like and love. Sounds perfectly sane to me? threatening to throw someone of a DZ and not allowing them to participate if they even talk or show people other judging methods...thats another story..

  21. The fact that this is the second time you encountered a worm/trojan that can only be INSTALLED by opening malicious attachments to emails or executable files that you downloaded, suggests you need to look for a solution closer to home. JC FlyLikeBrick I'm an Athlete?
  22. There isnt a single case of Trojan or other type Virus ever reported on the PF website. Nor do any of the reputable security scans report the website as such. Nor is it possible in the way you describe. A Trojan is not a program that activates or installs itself. The user has to download and install a program, in which the Trojan is hidden. Usually 'funny' email attachments or small bits of software installed. Unless you actually got prompted to download and install files uppon visiting the PF website (which no other person has encountered) the cause is most likely a product of your own internet/mail use, and looking for a new 'IT guy' is recommended.

  23. Be it some differences in inflation (a bit softer) and the suit having a bit more shallow angle of flight (a bit harder to fly for distance/speed), its quite comparable to the Ghost3. I did quite a few jumps on that one. Here is an oldie video of us playing with some Stealths https://vimeo.com/11931565 The Stealth2 was quite a step up in wingsurface. This suit would later be updated again (as the request for more fabric arrose) towards the Venom. Depending on the condition of the suit, and how well it fits, its actually not a bad price.
