    Learning To Fly A Wingsuit

    Wingsuiting is a fast-growing discipline in the skydiving and BASE-jumping world, and like all new disciplines in the sport, there are some potential pitfalls that this article might help you to avoid. Wingsuits can convert downward speed into forward speed/lift, much like a canopy can, up to a certain point. This allows the wingsuit skydiver to travel much farther over the ground than even the best tracker can travel. Like a canopy, there is a balance between weight and performance. Wingsuits come in a wide variety of sizes, but all are of a similar shape. It is a common misconception that size is related to skill, freefall time, and distance traveled. New wingsuiters would be well-advised to not be concerned about which suit they’ll eventually be jumping; suit styles, features, and sizes are constantly evolving. In other words, use the introductory suit provided by your coach and plan on a world of discovery after that first experience. How Should I Prepare For Wingsuiting? First and foremost, you’ll need a minimum of 200 jumps in the past 18 months if you’ll be jumping at a USPA dropzone. This is a BSR, or Basic Safety Requirement. It is highly recommended by both USPA and all manufacturers that you take a First Flight Course/FFC from a qualified wingsuit coach. There is no USPA “instructor” rating for wingsuiting, only manufacturer-issued ratings. Be sure the person providing FFC coaching is current and it is recommended that you seek someone with additional USPA instructional ratings. There is no difference between a wingsuit “instructor” and a wingsuit “coach.” Some manufacturers have elected to not confuse the USPA Instructional ratings with being one who teaches wingsuiting, ergo; “coach.” Tracking jumps with a focus on navigation will go a long way to achieving a good sense of navigation. Navigation is a critical component of a wingsuiting since we’ll be adding the potential ability to fly several miles from 13K. Concentrating on flying “quiet” (without a lot of body/limb movement and relaxed) is a benefit to preparing for a wingsuit skydive. Your coach may even require that you’ll do a tracking dive prior to the first wingsuit flight. There are some equipment recommendations to consider prior to making a first wingsuit skydive. For example, lighter canopy wingloadings are preferable. A good wingsuit coach will recommend or require a non-elliptical canopy for the FFC It’s a good idea to avoid ellipticals for wingsuiting in general, and most coaches will highly recommend (if not require) an AAD. Losing altitude awareness should not occur in a wingsuit skydive, but your body clock will feel “off” in most first wingsuit jumps. A hard helmet is recommended; wingsuits restrict movement. If there is going to be an impact of any kind in a wingsuit, it generally will occur at the front of the fuselage (your head) and your arms cannot be used to protect the head/face. Full-face or open face helmets both work. I personally wear an open face helmet, but many wear full face helmets. There is little doubt the wind can be heard more clearly in a full-face helmet. The sound of the wind is often used to gauge fall rate. An audible may promote awareness due to the potentially elongated skydive. First flights, like AFF, generally terminate at 5.5k, and most skydivers have a lower deployment point. The audible may help with the change in body clock and new sight picture at deployment time. Mudflap or chest mount altimeters are highly recommended; looking at your wrist may cause a turn or instability in the first wingsuit skydive. A good coach should be able to provide these things in the event you don’t have them. I personally prefer chest mounts for FFC’s as they keep the student’s head aligned with the body when looking at the altimeter. Get Taught The Specifics Of Wingsuiting Look for a coach that provides appropriate time to teach specifics relating to: Exits (Exits are the most dangerous part of any wingsuit skydive) Stable flight Navigation Deployment Emergency procedures/recovery from instability You should be doing at least two practice touches in the air as well. Your coach should make sure you not only know all of the above procedures, but assure you feel comfortable in all aspects of the process. The training process should be specific to the aircraft from which you’ll be jumping. Otters and Skyvans have a slightly different exit method than say…a King Air or Cessna 182. Wingsuiting is becoming more common across the world, and suit designs are available for the newcomer to the discipline. A good coach should have an abundance of suits so that the suit fits properly. Wingsuits for introductory skydives/FFC’s include Phoenix-Fly Prodigy, Shadow, and Phantom 2. Tonysuit offers the Intro model, while FYB offers the Access and Indy. All of these wingsuits are designed with beginning wingsuit pilots in mind. Some of them can carry well into a wingsuit pilot’s jumping career, while others will most likely be used for a couple of dozen jumps at best. Linetwists were caused by the student keeping his legs open on deployment. Be cautious about planning for larger suit sizes. There is a balance between wingloading and hang-time. A lightweight person in a very large wingsuit will be more like a “leaf” as opposed to a rocket, where a heavier person in a small suit can generate ridiculous forward speeds. Once you’ve determined that you want to continue down the wingsuit piloting path, you’ll likely figure out whether acrobatics, relative work, flocking, distance flights, or hang-time (time aloft) is the goal. There are suits that can meet most of these goals, while some suits are better designed than others for specific tasks. Performance should not be an objective in initial flights. There are three goals/TLO’s in the FFC that I teach: Safe/clean exit (Avoiding the stabilizer and being stable) Navigation back to the DZ Clean deployment free of malfunctions Other coaches may provide other emphasis, but at the end of the day, the goal of the first wingsuit flight is that it is a fun skydive with a heavy emphasis on safety. You’ll experience a different ground rush, feel the sensation of true flight, and find the wingsuit a very different experience from other skydives. A list of wingsuiting coaches may be found on the websites of various manufacturers. We’re looking forward to seeing you in the flock!

  2. That was a great listen! Sandy is a walking encyclopedia of our sport.
  3. Search the threads, there are several commentaries. In short, the bitrate and aperture of these types of cameras are too small and low to function for a high-speed sport. https://vimeo.com/41088648 https://vimeo.com/40985675 is at 16mbps, and these are a pair of one of the best offerings out there. And of course the usual...200 jumps, please refer to the now nearly dead thread on small camera incidents.
  4. Replay is a US Company, their tech support second to none, and they are built of aluminum, not plastic. Incredibly durable, great picture, low profile...there is a reason I've used them on several commercial shoots, and why they were rated very high in the DZ.com camera shootout.
  5. Contact Adam at Replay. You can buy lens kits for a few dollars; might as well experiment with one lens cover to see if a small hole fixes the issue. I'd also suggest checking the O ring, and perhaps use a very light coating of silicon ala CYPRES kit. Card speed is critical. There isn't a week go by that I don't hear from someone who has slow or counterfeit cards. So you're formatting outside the camera? That seems a tad odd, but if that's what XD told you to do...
  6. you might want to ask this in the wingsuit forum. However, you'll likely have better openings with a wingsuit and Spectre. I jump Storms (either 135 or 150s, rig dependent), and prefer them over the Spectre. However, at your lower jump number, the Storm might be a bit too aggressive. The Spectre is an ideal wingsuit canopy, IMO.

    windows 10 and Vegas pro 12 and 13

    Vegas 13 is running smoothly on my Win 10 installs... Haven't reloaded 12, however.
  8. The dropzone will manage that for you; even as only a visiting jumper, I still had to purchase a membership for APF. It was no big deal. Byron Bay is a gorgeous DZ with a terrific staff. Ask for Jose, he'll get you sorted. He's also a USPA licensed jumper in addition to being an APF instructor.

    Sony mounts

    Wait, what?? You're comfortable with a GoPro mount and not a Sony mount? Sony's mount covers nearly double the surface area of the competitor. It is of a softer material that not only dampes vibration, but also doesn't shatter on impact. Side mounting the AS100v upside down in the Helmet side mount (because you want it on your left side), is a solid option. The AM1 is very solid as well, for a top mount. Put a GoPro adapter on it, and your video will greatly suffer. The whole fulcrum point is why GP is inherently unstable, and why most pro's use cages vs lick n' sticks.

    Soft links identifier

    That's a useful resource, thank you for taking the time!
  11. Thank you for sharing this story. Snags don't occur only on deployment, but that's an easily forgotten point.
  12. EXCELLENT article. I don't know that newbies are "encouraged" to be unsafe, but the groupthink often suggests "if I can do it, I don't see why it would be difficult for you"... Frequently I run into skydivers that think from their own ability and perspective vs the ability and perspective of the person they're communicating with.
  13. Have you had a rigger measure the lines? Is there any play in your brake lines? The Sabre 1 has a relatively light front riser pressure, or at least the 170 I had did. Closed cells/bucking were never a problem for me. I'd suggest measuring for line trim, or having someone do it for you. http://www.performancedesigns.com/docs/linetrims/LS_120-170LT.pdf
  14. Tony makes an awesome camera suit. I prefer the large wings; it's easy to "get rid of" wing than it is to grow bigger wings.

    Sony FDR-AX33 test footage

    "Active" usually does better these days... Nice footage. Youtube compression does a terrible job. Vimeo is a tad better. BTW, if you want to see it more amazing...shoot 4K, stabilize it gently in post. The extra resolution does indeed make a diff when outputting HD or 2K.

    360 degree gopro

    it's already been jumped. So has the one it's copying.
  18. Forget tandem editing on a Mac. It's a waste of time for any mpeg format on a mac, it's just that simple. Without going into the several technical reasons why...It shouldn't be taking more than 10 mins on the slow side from ingest to output to thumbdrive. I don't really feel up to writing a novella, but since we're friends in real life and online life, I'm happy to do a consult with you. I'd start by recommending you skip 720p and go to 1080p, since people are generally expecting "full hd" these days. The slowness is the Mac. No, you don't have a lot of options when ordering thumbs.
  19. Another clone of the SureShot system, which already sells quite well. Both are far too slow for skydiving purposes

    HeroCast for skydiving?

    At this point, this particular solution will not work for skydiving. There are solutions, but nothing small, nothing that is currently stable enough to use day in/day out, and cost is quite high. Frequency, power, and antenna specifics prevent Herocast from being a viable option. I'm very surprised to see them suggest at all, that 4000m would be "likely." Teradek has some answers, but again...cost is high. Editing on the "fly" isn't really viable either, as a file needs a closing header, so cuts aren't possible. video has to buffer to be seen, and in that process there are stops/starts. Cutting on the fly is exceptionally challenging, made easier only because we'd know what was "next" after an exit or deployment. Beyond that... Great idea for a problem that doesn't exist. Streaming to the ground however....is a great (and old) idea. It'll happen, just not right this moment.

    Sony X1000V

    Actually, Adobe's stabilizer will crop AS MUCH as 10% of the image, not 90%, and it is quite usable. However... there are much better stabilizers out there should you need to stabilize. A solid platform rarely requires much stabilization. I haven't dug into PlayMemories to see how/if it will display the altitude that the app alleges to display, but then again, I don't use PM for anything at all anyway. If I get some free time, I'll see if I can figure it out. It is definitely in the Developer kit as a vendor embedded option. Yes, the X1000 is a terrific little camera.

    Sony HDR-CX405?

    If the ActionCam series would work, I'd consider that route. Small, amazing quality, stabilized, lots of options.

    Proof that wingsuit can go up?

    We see this at practically every Performance Comp...been a known thing for years Take a peek at some of the GPS logs; it's very clear where in speed rounds, competitors "pop" up sometimes as much as a couple of hundred feet from their glide path. As far as this video goes...a wingsuiter flying flat, viewed from a highly-loaded canopy descending at a rapid rate does not suggest the wingsuiter is flying "up." The "up" is a very temporary state of flight, not remotely sustained. Spend some time looking at the speed rounds on Paralog. You'll find quite a few where there are relatively significant "climbs."

    Sony AXP33 4K camera

    IIRC, the HypEye won't work with this model. Trunk may have certified it, but I believe it uses a different protocol. The camera itself is great ('ve used the American model). Not a fan of the built-in projector, but it's a nice novelty (useless in any but a pitch-black room).
