  1. Notice: that's flocking, not f1.0cking. That's how it's done. These guys won't be embarrassing to watch with Shuttle launch in the background. 2010. The year f10cking died.

  2. Ok, fuck me dead, but I don't understand one simple thing: why, oh why, after three decades of desktop video production, we still see and fight the stupid issue of aspect ratio?!?! Meaning, you post a video somewhere or watch the video and its aspect ratio is distorted from normal? Why oh why in the era of artificial intelligence, the computers still cannot make square pixels be square in videos?! Why oh why the last time you saw an image with distorted aspect ratio when you used Netscape Navigator 1.0 and yet 20 years later the video is still hit and miss?! What is it so special about video, compared to stills?! WTF? WTF? WTF? (I'm just tired of uploading a video, say to youtube or vimeo, for many times before seeing really square pixels. Jeez, life doesn't have to be that hard! ) Ok, I feel better now. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  3. A gun for skydivers? That's all?! How 'bout a grenade? You have a special handle that cuts away a grenade concealed between your butt cheeks. When hijacker orders the pilot to jump and everybody is out of the plane, you pull that handle and jump. Astalavista, baby!

  4. I think most of the effect of palms facing backward comes not from the aerodynamics of palms themselves, but from the difference in how your shoulders are "cupped". Try it and you'll see that your shoulders are a little bit wider and a little bit more cupped when your palms are facing backward. Also, since the "material" (read: meat&bones) has pretty much constant volume, being wider also means being thinner. Wider and thinner, more aerodynamic profile of your shoulders. As for the miniscule fraction - they are flying parallel to the slope so any miniscule fraction can make a 0.5m difference - enough for gold. From that Pine Mountain link above, the 143.5m record is only 0.7% longer than the previous one. So we may not notice 0.7% on tracking skydives or base jumps, but for ski jumpers it's the difference between being a hero and being a zero.

  5. No, the only requirement for the device to work correctly is to fly straight, no turning, and no sudden changes in pitch angle which introduces centripetal forces. You can dive, do planeouts, flares, collapse wings, whatever - as long as you fly straight, the device will always show true L/D at each moment. And obviously, it doesn't depend on winds, as it's driven only by relative wind. Pure Fucking Magic at work. It's insanely beautiful, because it seemingly doesn't have to be this way (you would think, as you did, that accelerations will distort the readings and render them meaningless). We physicists can feel the beauty of complex equations magically collapsing and revealing concise, beautiful result. You can experience the pure fucking magic yourself. So you can be doing a horizontal planeout after a massive dive and although your glide ratio will be infinite (or even negative if you go up) for a few seconds, but L/D Meter will magically show the finite L/D at each moment (e.g. 1.0 as you'll most likely be cupping the armwings to flare, which kills L/D). The vane will be horizontal and yet the bubble will be staying at 1.0 mark although it's not the highest point of the curve! This is because during level planeout, you experience deceleration which makes the bubble move to the point which is the highest relative to apparent gravity. And during the dive, although your glide ratio will be near 0, L/D Meter will still magically show the correct lift-to-drag ratio. It's magic... pure flying magic! Magic Curve is another beauty. It is a curve designed to have equidistant L/D tick marks for easy reading and precision. At each inclination of the vane, the tick mark corresponding to L/D of that angle (L/D = 1/tan(Angle)) is the topmost point of the curve, and that's where the bubble is. For example, if the vane is inclined at 45 degrees (L/D = 1), the 1.0 mark is the topmost. At 19.6 degrees (L/D = 2.8), the 2.8 mark is the topmost, and so on. Magic Curve is also a beautiful analytical formula. Try deriving it yourself, you'll have a lot of fun.
  6. Also, to point their difference from skydivers/basers: THEY DON'T HAVE PLAN B!!!!!!!!!!!!!!!!!!!!!!!!!! That tells a lot. Look at them flailing like taken by surprise when things go to shit... We? We always think and train for plan B. PLF, all kinds of malfunctions, etc. etc. I think they'll make any AFF instructor wish they were never born! They suck, we rule. End of story.

  7. Uh-oh... Ok, ok, ski jumpers WOULD make fantastic trackers.... It's just they'll still point their toes to their heads like geese on landing. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  8. It'll be funny to see them pointing their toes towards their heads on their first skydive, because that reflex is engraved in their muscles to control what their life depends on: skis.
  9. A few more pics - these show that L/D Meter can be built to measure any range of L/D. This is the first prototype (or rather mockup) I made that had the range of L/D from 0.0 to 3.6, with 0.2 step (in the 2nd picture, you can see the bubble at ~2.8; if you measure the angle the vane makes to horizon, it corresponds to glide 2.8). It turned out to be impractically big to mount on a long stick on the helmet. The 1.5-2.5 version uses a portion of "Magic L/D Curve"™©® to make the device more compact. For our World L/D Record, I'll build a version with the range 2.0-3.0 with 0.1 step. Besides analog version, a digital L/D Meter, with accelerometer and display, is in the works. This one will show any L/D you can produce.
  10. Not necessarily. What they're trained for for hundreds and thousands of jumps is maximizing the distance in very particular configuration - subterminal track with high horizontal speed and quite specific range of body pitch angles (i.e. their body is never head low). That would not necessarily translate into a great track in BASE or skydive. Their pitch habits may scream "nooooo!!!" to going headlow but that's exactly what they need. And then there are skis which also produce lift and drag, for them it'll probably feel weird to feel their feet are free... So I think they'll suck and any AFF student can outfly them on their first tracking jump.

  11. No, no anger here, only laughing my ass out. You go well with Sapporo, 22oz tall silver can or premium German beer. Nothing is more hilarious than some stranger yelling from the other side of the street: "Hello there, i'm a FUCKING IDIOT!!!" Can't wait for your next "War and peace".
  12. Now, THAT'S FLYING! Increadible job, Robi & Co.! 2010. The year f10cking died. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  13. Whatever, dude. Stop following me like a maniac. It's not the first time you crying "you turned me down" love song. Is it my tits that mess up your brain? Stop running after me like a little barking dog after a bus trying to bite the wheels. Get over that traumatic experience you obviously had when I said "I'm maxing out." Get a life.

  14. Awwww, another drama queen cries up... I was not interested in group flying at that moment, I wanted to do a few solos from CASA at Lake Whales. So what's your problem? It's your want vs. my want. "Waaaaaa.... he turned me down.... waaaaaaa". Jeez, WTF is wrong with you people. And when I jumped immediately after you and your friend, I couldn't get down to you no matter what. I made at least full 360 (maybe 2, don't remember) and still couldn't match your fallrate, all while braking hard. And then I see that at 4K or so, you're still a mile away from DZ AND moving AWAY. That's when I thought, "WTF, these guys have no clue" and turned back to DZ (I was probably 1000ft higher). You still landed at the DZ thanks to honking 30mph+ winds at opening altitude, 20mph on the ground. I'll post the video if I find it. It amazes me that at 250lbs and flying a small suit (worn out Phantom-1), I still have to do 360's and still cannot get down to f10cks, even 2-ways like yours (two light, athletic guys in Vampire and Ghost). And yeah, I like solos best of all. I only do non-solos with my friends and only to FLY, not to FALL. Get over it.

  15. Option D: Fuck off, little bitch! Seriously, what is your fucking problem? Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  16. And on the SEVENTH thought: Since outside camera essentially makes an N record an N+1 record (cameraman will be flying at the same L/D), N=1 record does not make much sense - it is, in fact, group flying, not solo flying. Which again, slightly impedes the achievement of the highest L/D possible. And so, let's have two categories of World L/D Record: 1. Solo 2. Group Solo: only 30s video of L/D meter in flight is needed. Max L/D is the winner. Group: 30s of video of L/D meter AND of the group in the frame - cameraman will be flying above the group with camera pointing down at the device and the group. Cameraman is included in N. Either max L/D wins (no matter N) or max N for the same L/D (within +/-0.05 margin). Example: 2@2.42, 3@2.50, 5@2.46 (notice L/D can go down slightly from the previous record, as long as it's within error margin) , 9@2.43, 2@2.71, 3@2.70, etc. It's that simple. L/D Meter has error margin of about +/-0.1 but when 30 samples are averaged the result will be more reliable, so the final 0.05 margin makes sense. L/D Meters will be provided by me at no cost other than shipping. (you'll have to return device back, though.) I'll try and have several by this summer.

  17. Winnie Chang, not Wendy. Haven't heard from her for a couple of years. I feel great. FFF's flying at top notch performance levels would be awesome. Imagine a WS N-way flying by a CRW diamond AND OUTPERFORMING their glide. With smoke on each pilot and cameraman flying on the other side of CRW formation as they're passing by... A sight to behold. 2010. Flying wins. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  18. I agree, Scott. Flocking should not sacrifice the awe of flying. My only vivid memory of flocking was this jump we did at the Ranch in New York about 3 years ago. A girl from UK was visiting, Winnie her name, she's well known in BASE circles. In the plane, usual question: "So, what do we do?" (there was her, me, and 2 or 3 other guys) She says immediately with her beautiful smile, "We max out." We jump out, and from there it was pure flying magic. She was the first, we followed. She was hard to follow, I maxed out as much as I could and matched her glide (she was in S3, I think, I was in in my trusty Phantom1). It was one of those magic carpet rides when you feel that even if you move your facial muscles as the grin covers your face, you're gonna fall out of the sky like a rock as the air cannot physically support you. This sensation is magical, memorable, awesome. So yeah, there's f10cking, and there's real flying with like-minded pilots. 2010. Flocking reinvented.

  19. Jesus Fucking Christ, lurch, I serve you your own shit and you're "disappointed"?! Should I have topped it with a swirl of whipped cream over caramel syrup? Ok, ok, let me try. Come closer. Closer. A bit farther. Ok. Now lower. Lower. Ok, just perfect! Now, open your mouth and close your eyes. Ready? i YURINATE ON YOU!!!!! Weeeeeeeeeeeeeeeeee!!! I hope you found what you've been looking for, as you've been stalking me in this forum like a lunatic. Apparently, you've just been starving for the Golden Shower.

  20. Lurch, What exactly is wrong with you, anyway? I can't figure it out myself, but my first guess would be, A Lot. I mean really...back when you were a wannabe wingsuit pilot you had such a positive attitude. Now its like I wonder did you have some traumatic flock experience, went to Florida and Chuck Blue pissed in your wheaties one day or something, (an act that, now that I think about it, I wouldn't put past him if you fucked with him). I mean what was it? You got gangraped by a bunch of wingsuiters dressed in pony suits? Play under powerlines too much as a kid? Late night sneaky uncle? One too many servings of paint chips with extra lead? Reading your stuff is kind of gruesome but entertaining, like watching someone repeatedly stabbing themselves in the forehead with a dull pencil. I know its not going to be fatal or even do all that much damage really, but I can't help thinking "God, thats gotta hurt..." -Y Impossible is for people who can't fly.

  21. No, it's not variable due to position on the body as long as the vane is in undisturbed air. In my test flights, if the stick was less than 2ft long, the meter will show unrealistic values (like 2.4-2.5, which I know from independent measurements I cannot do in Phantom 1, 2.2 is pretty much the limit for me in this suit). Helmet or belly are pretty much the only places where you can mount this thing, and helmet mount proved to be a bit awkward due to inertial and drag momentum created by the stick when you move your head. The device is actually not calibrated, it is calculated using my secret magic formulas (including the positions of L/D scale ticks; the magic curve is designed to make them equidistant) and precision laser cut. A digital meter, which is scheduled for summer, will have to be calibrated during installation of accelerometer. For our World L/D Race, digital version would work better. The device is based on the idea here. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  22. Yo, did you just call yourself "Nobody"? Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
  23. Here's the L/D Meter prototype I made and successfully tested last Spring. It measures L/D from 1.5 to 2.5 in 0.1 steps. It worked great, the results were consistent with independent measurements from BASE jumps using Wingsuit Equations. (2.1-2.2 in Phantom 1, that's my typical numbers in Phantom.) In the future version, it'll be a belly mount since having this thing on the head felt kinda weird. Of course, only one pilot in the group needs to wear the device. Also, it'll need a small camera on that pole pointing at the bubble. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio
