  1. Has anyone had to deal with MCL / ACL / reconstructive knee surgery? If so, how long post opp. did you stay out of the tunnel? Also, presume they won't let you fly with a brace, right? There's about a 0% chance my brace would go under my tunnel suit lol.

    Any advice would be really appreciated. I've lost surfing / skiing / skydiving / kitesurfing for the next 10 - 12 months so I'm hopeful the tunnel is not the same situation.

    ***Got in the tunnel tonight for the first time since 2001... and got my @$$ kicked on my back. I think I learned a lot but was humbling while indeed fun.

    Thanks for the answers guys - I can see this isn't a fast progression.

    I met you last night standing at the counter. I was filling out the Packing Data card for that brand new Infinity you saw sitting there.

    If you have much time set up in there, let me know and I can come push you around a bit. It really helps to have someone in there to sort out all the new habits you will develop.

    Congratulations getting back in there. Walls are weird at first. You'll pick it up quicker than you think if you have a bit of guidance.

    Thanks for the offer, Hookit. It was nice to meet you. I'm going to grab 1.25 hours to take advantage of the "weekly pass" - so hopefully sort out a few more things and start moving to sit fly soon!

  4. Hey guys,

    I'm in the SFBay area for work through August, staying in Newark and noticed the tunnel is rather close :D.

    I've been wanting to learn headdown in a tunnel for a few years now - through a quick search I didn't find answers to my questins below - any guidance would be awesome!

    - How many minutes / hours does it take someone to be able to fly head down in tunnel?
    - Do people go with tunnel or external coaches in the Bay area? (hope this is loaded question - seriously know nothing about this)
    - Any pre-tunnel work that can be done? (such as learning to do to an unassisted hand stand?)


    Experience: 3200 jumps, 8 years, mostly tandem video, tandem - only about ~ 200 freefly jumps (can sit fly, and back fly at an intermediate level)

    Thanks guys,

    Dave

    After an argument at the DZ this weekend, I thought I'd post it on here.

    The argument started out with: which canopy would be more aggressive?
    A Crossfire2 loaded at 1.44 or a Safire2 loaded at 1.55

    I'd guess the xfire just had it at these loadings, but at what point would they become similar?

    They'd be a Xfire2 139 and a Safire2 129 with an exit weight of 200lbs



    That's an interesting argument. A Sabre/Safire loaded at 1.4 versus a xf2 loaded at 1.4 makes for an easy argument but I think in this case you have to dig deeper.

    On the Xf2 linetwists (to some extent), packing, turbulence, low turns and accuracy will be important areas of consideration. On the Safire class canopies - - everything would be milder except for slamming into the ground (IMO) - smaller canopy, less drag and probably more speed when in the power zone so the consequences of gross pilot error will be magnified.

    Chances are - if someone doesn't think a person is ready to jump a xf2 at 1.44 then that same person will not be able to make the argument they can jump a safire at 1.55. Tough call with a lot of subjective input I'm sure but any semi elliptical canopy can still be a bear - as far as I'm concerned Sabre2, Safire2, Ntiro/Nitrons are all high performance canopies at the right wingloading. And remember: once you get below 150 every canopy is a high performance parachute because of the shortened lines and reduced drag.

    better than a gopro 2?



    I think Drift cameras are a Great product with Lots of innovation but a NZ guy I jumped with this summer had a lot of trouble with his.

    He went through 3 cameras in 4 months before getting a full refund and buying a gopro. That said, assuming the manufacture fixes the few bugs that we've seen it will be an AWESOME piece of equipment. Def. on the right track.



  7. Any extra speed with a Velo will hurt. On tandem video I'll slow down before they open if it's a big TI & student. I rarely go freeflying with my velo because I can't slow down fast enough - I'm a bigger boy B|.

    The only thing I recommend doing (and at that only with camera wings) is backing up ie putting your feet up and your hands out before pulling. It promotes a cleaning opening and then does a gentle 180.

    I had the most trouble on a 96. My 96 and I just did not get along but my 90 is incredible. The smaller the velo the better the opening at least compared to a 120, 111, 96 and 90.

    If you have a small velo spread the risers to keep the slider up. Don't pull and don't pop your break or you're fucked. If you're spreading your risers and it starts fighting you lean into the turn to keep excess tension from pulling the risers out of your hands and flinging you into linetwists.

    Never been spanked by a velo when I opened slow - so slow down a bit more and you'll be fine.

    try to kick out of it before ti release the drogue handle????

    if that does not happen you'll probably got wrap in tandem main canopy.
    1. try to swim out of it while looking at your alti.
    2. if you can not swim out fire reserve at harddeck???
    3. and throw out your main???
    4. Video guy is fucked.



    I have over 2000 tandem camera jumps and never found myself entangled on a drogue however I witnessed a camera flyer becoming entangled.

    Porter exit, sigma system and experienced camera flyer with many camera jumps.

    Situation: It was a late leave with a somewhat early drogue throw. Separation was there but the video flyer was right on the drogue path and was hit in the face by the drogue at line stretch.

    The drogue hooked the ringsite and stayed with the camera flyer for a number of seconds. The camera flyer's ring site eventually broke off. The camera flyer flew their body during the duration of the event and plastic screws broker off the ringsite (if I recall correctly) and the drogue cleared. It was over before it started.

    Here is the thing - as a TI if my camera flyer is flying stable with the drogue and I am stable with the student I am inclined to give them some time to clear the drogue. Its far more dangerous for me to deploy a reserve below a wrapped camera guy then to give them some time. A drogue entanglement will most likely come from a camera helmet - dump your gear and clear.

    If they are caught by another part then their helmet there are a lot of problems coming up fast.

    I tried to disconnect my RSL in freefall the other weekend as a TI with a fullface Z1 on. It was fucking hard. Clearly, I didn't disconnect it but with gloves on and a Z1 full face it took over 3K feet to confirm I had the pulltab in hand.

    This situation requires briefing for both instructors and video guys. A TI needs to understand when they are in imminent danger or have some time to allow their camera guy the chance to clear. Obviously, I don’t have any answers. Just some though while thinking through the situation myself the other week.

  9. The posted video is the one in question. A few points - I fly two velos 90 (2.66 :1) and 96 (2.4 :1) unless faced with an emergency situation I would never open at 2,0K with them. The canopy I was on was my nitro 120 (1.8 :1) - which is a "docile" canopy that I NEVER previously had trouble with but the video clearly shows even a semi elliptical canopy will screw you.

    With respect to my altimeter - I recommend against using a Suunto Core for skydiving operations. I have 1000 jumps on my Core but it refreshes noticeably slowler. While it looks nice the altimeter is not the best for skydiving. I recommend the Altimax, X-Lander and Vector as altimeter replacements – you have to make the decision why you want to jump a Suunto, a digital altimiter or a traditional altimeter for yourself. Since my 300th jump all I've used have been Suuntos and I currently use an Altimax. My Suunto Core is now my water watch for kiting and surfing.

    With respect to being stupid for opening at 2K... I'll agree but let’s keep in mind our BSRs say we can do that. I'd advocate for a minimum opening altitude of 2,5K in a second. However, though I normally do not open this low, it was my opinion that you should always be comfortable to open at 2K which is what I was practicing after this fun jump (it was just a fun jump.) You never know when you'll be forced low especially on a big way skydive. I would generally open with my least performance canopy at 2,000 feet every 200 or so jumps either on a hop and pop or solo – it just so happened my mal occurred on a opening I do maybe less than 4 times a season. I was in the PEAK of my currency when this occurred and just after a very extensive personal EP review which included reviewing a low altitude deployment to breakaway.

    Reserve - I fly a 90 velo and a Smart 150. You won't find my ass under anything smaller. I've had linetwists on 3/7 sport reserve rides and I don't want to have a malfunction like the one I cutaway from. Also, it was nice to have a slow canopy to land in a tight spot. I’d advocate RSLs for everyone but the most unique cases. I’m weighing the pros and cons of having an RSL on my velo rigs right now.

    Was it dumb? Yes. Did it suck? Yes. I hope people in the minimum opening altitude threads look at the video and reconsider their opinions. I am proud of the way I handled the situation and I hope low jump number low pullers take a moment to stop and think about what they are doing.

    Thanks,

  10. Phil -

    Thank you for the letter in USPA's Parachutist. While I regrettably inform you that your letter contains material inaccuracies your point is valid. I'll save correcting your letter and skip to why the video is on youtube - may I politely suggest you review the accuracy of your letter.

    The "low cutaway" video posted on youtube is there as a safety and training reminder that no matter how many jumps you have (in my case +2,000 when the video was filmed) things can and will go wrong; more importantly, at the most inopportune time as evidenced. I was opening at 2,000ft AGL, while holding my D license, and decided to make the video public in response to a number of deaths due to low cutaways since my time in the sport.

    If you analyze the video you'll see that from the moment my canopy starts spinning to the time I cutaway I'm attached to my canopy for less than three seconds. In my review and in my personal emergency preparation this is how a low deployment malfunction needs to be handled. Moreover, I clearly demonstrated that altitude is KEY over stability and while it was rather scary kicking out of linetwists flying away from the airport my decision to open unstable was contributing factor to being able to negotiate a difficult landing safety. The aforementioned decision provided me with the altitude and time to set up a good pattern, confirm my obstacles and instill confidence in my approach.

    I hope everyone who has viewed, commented or debated & discussed the video in question has made note of material S&T points. In the unlikely event people view this video as a cowboy post in lieu of a learning tool I’ll provide my personal points now. Most IMPORTANTLY:

    1) Know your rig - be proficient with your emergency procedures. A fast, clean breakway was material to my safety.
    2) If faced with an emergency know how to react. I.e. rehearsing a low cutaway mentally many of times before helped me take action quickly. I knew I had less than 5 seconds to make a decision and act all the while understanding that a clean, calm break away was important.
    3) Below 2,500 feet deploy your reserve immediately after breakaway regardless of a skyhook, rsl or camera helmet. I had my camera helmet on and no RSL for the deployment. I hope my video ends the altitude versus stability arguments. Line twists on a reserve may not be pleasant but impacting at line stretch or less is far worse.
    4) Forget about your handles and get your reserve under control - especially if you have a feeling you’ll be negotiating a difficult landing. I had no qualms about the ribbings I received for loosing my handle.
    5) Decide and commit to your landing zone early. Confirm your winds. Check for hazards and get into the landing zone safely without a low turn.

    Phil, thank you for your understanding and I hope you found some educational value in the video. In the unfortunate event you feel there is no value please refrain from posting negative remarks and let those that do get something out of this video process it. If I saved one life with the video or provided one new jumper with a "what not to do" then I am proud of my decision to post the video and I am happy to have provided some positive influence.

    Thanks.

  11. Listen dude. You’re fucked for information on here so cut the shit, yes?

    If you want to jump the canopy you want to jump then do it with the understanding you’re getting in over your head. You are more likely to get killed, hurt or die tomorrow under your current canopy than one that is one or two sizes larger and that's a fact, that goes for everyone.

    So stop posting and make your own decisions and understand what they are. Most importantly, just don't hurt anyone else.

    I followed your progression; not as aggressively but aggressively. I was under a XF2 1.4 : 1 @ 320 jumps and under a velo at 860 jumps. But - at the end of the day I got lucky a couple of times.

    I had close to 3,000 jumps when this happened; I got real lucky to have a bummed ankle and the world’s most painful grass rash: https://picasaweb.google.com/Kramar.D/DonTGetInTheCorner#

    Everyone misses - the question is when you miss do you have enough margin for error to get out alive and walk again, get lucky or just become dead. To add: And right now, you do NOT have that margin.



  12. Are you flattop or side mounted most of the time?

    I have a Velo 90 2.6 : 1 and a Velo 96 2.4 : 1 and both work great for video. Your biggest problem (depending on your DZ) will be canopy traffic below you. I tend to brief people who will be landing in the same landing area as to what type of turn I will be executing and my landing direction. Also I explain to them if I see an opportunity to pass and go low on them to view it as a safety thing rather than me cutting in front of them in the landing order, which obviously they agree with. My experience is usually with no more than 3 other video canopies and 5 sport canopies in the air with three distinct and separate landing areas; any more canopies and I don’t feel comfortable swooping for landing. We have a dedicated experienced pilot landing area which helps traffic a lot. So assuming canopies won’t screw you I don’t think it’s a problem.

    With the preceding said I had my first entanglement last year after four years of jumping velos and it was some scary shit. Video is on youtube you can search for KramarD “Main Camera Helmet Entanglement.wmv” to find it. I was able to keep my helmet after it cleared the main by biting my tongue switch. A fried of mine lost his full setup two years ago when a FX 2.3:1 riser slapped his chin cup release.

    Hey guys, what is better for a Photography Lens, to use for skydive/tandems
    Sigma 10:20mm or Sigma 15mm?



    Pentax K-7 Sigma 15MM seems to not be as wide as I would like. 7ft down and away from the tandem pair I have trouble getting the pair in frame with the drogue.

    I LOVE my 8MM lens but no AF (infinity after 3ft I believe.) But it is pretty darn wide and takes some getting used too.

    Could anyone post a sample picture or two of 10mm results? The K-7 has a crop factor of 1.5X. Attached is a Sigma 15MM @ 1.5X factor.



  14. Our DZ plain and simple sucks for swooping. We have a tiny advanced CP landing area and occassionally if you are a touch high then your going to run onto the ramp... not a big deal but would be nice to not have to run it out on the ramp.

    I have over 1600+ Velo jumps in this landing area so I'm not overally concerened but I like the idea of know this emergency manuver. For having that many high performance landings I should know how to do it :)

    A canopy pilot was coming out of his swoop



    Do you mean coming out of the dive? What are describing doesn't make sense unless the guy was stabbing out of the corner.

    If you're in a dive, you can stab the toggles and all of the energy goes to arrest the dive. Once you roll level, if you maintain the input, you go back up. If you release the input, you might just be able to put your feet down.

    If you're already level with enough speed to go another 100 feet, and you stab the toggles, you'll shoot back up in the air. If you watch guys do a zone accuracy stall, you'll notice they pop up before they get the canopy to stall and drop them straight down.

    What you may have seen was a guy who didn't really have 100 ft to go. He might have been 'out of gas' and hit the bottom of the toggle stroke. At this point, the canopy in a low energy state will not casue a pop up and just drop behind the jumper as it begins to stall.

    If the jumper allows the stall to continue, it will hit the gournd behind the jumper, and mostly like pull him down backwards in the process.

    If the jumper throws his hands up, the canopy can return to 'controlled' flight, but it will lack the power to support the weight of the jumper. Provided that the jumper puts his feet down as the canopy coems back over head, he can avoid being pulled over backwards.

    The concept is that if you have the energy to go another 100 feet, there's no way to stop the canopy with doing something with that energy. If you insist on going in a striaght line, that energy makes the canopy pop up, no way around it.

    Now if you want to stop right away, say to avoid an obstacle if your swoop is going too long, Brian Germains 'hockey stop' is the way to go. The hockey stop is basically a hard carve to either side where you turn as hard as you can while maintaining level flight. What this does is take all of the energy your canopy has and applies to to making the carve, not going in a striaght line. If you dedicate a huge amount of the energy to the turn, your overall distance travelled forward will be reduced, so the manuver both turns you away from the obstacle and consumes the majority of the energy your canopy has helping you to get stopped quicker.

    The reason it's called a 'hockey stop' is because just like a sudden stop while on ice skates, you turn your body sideways to the line of travel while performing the manuver.

    It's really a valuable skill, and one that every swooper should learn once they have a grasp on how to carve. It's just a matter of taking the carve to the highest degree and holding it there until the canopy is 'spent'. It's an absolute 'must have' before attempting to swoop in an unfamiliar area such as an off-landing. If you find yourself down on the deck looking at an obstacle you didn't see from 1000ft, you need a 'tool' to solve that problem, and that's the 'hockey stop'. Until you can perform that one with a good degree of success, off landings should not include a swoop.



    Everyone: Thank you for the replies.

    Dave - he was not in the corner. Mid to end swoop - and the more I think about it the more I think it was a "hockey " stop. I only had about 100 jumps when I saw it so Jesus that was a loooooooong time ago.

    Does anyone have video to point to the hockey stop? I'm at work and unfortunate not able to boot up youtube but I will check out the clips when I get home. How much lateral space does this use?

    For me - I've been shortening my swoops when necessary by very aggressively doing a hard super man while switching from rears to toggles as soon as I determine I'm long. I drag my feet as anchors into the ground to help bleed of some energy. Usually takes 75 - 100ft off but I presume there is a better way of shortening the swoop which seems to be mentioned above.



  16. A few years ago I saw a pretty neat trick and am wondering if anyone has video they could point me too...

    A canopy pilot was coming out of his swoop, moving at roughly 20 - 25mph with, I would estimate, 100ft more to go. He toggle stabbed the shit out of his VX and basically used the canopy as a drag chute and let his hands back up to come to a stop and stand up (there was maybe 5mph head wind).

    I'm not talking about a zone acc. stall but if anyone has video of a trick like this I would be interested.

    Is there a chart anywhere for how many mph you will go on a canapy based on your wingload? I searched the forums as well as google and didn't find much.


    Are you a robot or do you have an instrument panel for flying a canopy? :S

    Speed, trim and angle is subjective under a canopy. You do not need speed and you suppose to fly by your senses.



    What the hell kind of response is that? I feel like you wasted too much time typing that FYI. Hey, +1 to your post count.

    I have had my mind set for quite a while on getting a new Crossfire 2 139 this summer. I finally saved the money to get one. I did a ton of research into what my next canopy was going to be. I left no stone unturned...........or so I thought.

    I was minutes from pulling the trigger on the canopy and a friend asked "Don't they have a problem in turbulence"?

    I laughed and assured him this was not a problem, however, a little seed of curiosity was growing in my mind.

    I did a little looking into the matter and as it turns out............there is a history of the Xfire collapsing in turbulence.

    It seems that the problems stem from around the time of a recall where a bunch of Xfires had to go back for re-trim.

    This concerns me a bit because I jump in the Midwest where it is ALWAYS windy and ALWAYS turbulent.

    SO..........is there any more truth out there to this story or am I being paranoid? I am about 220lbs out the door so I will be loading it about 1.6.

    I currently jump a Stiletto 150.
    Cheers!
    EVOL




    I jump at a very turbulent DZ where either southerly or northerly winds give us a lot of trouble in conditions as little as 15mph. (Ridge to the north and sitting at top a ridge with slope to our south.)

    I have 800 jumps on 149/ 139 xf2s and not a single problem. They flew through turbulence better than most canopies.

    has anyone used or know much about the pentax k-x digital camera. it all checks out to me from reviews but wondering if it takes a toung switch or if there are anyother problems it might have as a skydiving camera. anyone know?



    It’s a fine skydiving camera if your comfortable firing stills off of the button. K-x does NOT have a remote shutter release port but you could mount an IR remote on the lens and work around that way.

    I flew a Pentax ist DL for 4 years; it shit the bed this past winter when I was shooting some none skydiving related stuff.

    The Pentax K-7 is supposed to be an amayzing camera for the price point. Avaliable for 300 more you get a dedicated remote port, better video options and a very competitive camera.

    I recommend K-7; K-x only if you’re doing tandems and are ok with firing stills off yourself. I will be flying the K-7 this season. I have so much high end Pentax glass that I couldn’t imagine acquiring a 8, 15, 20 – 105, 55, 100 – 300 lenses from Cannon or Nikon.

    Transitioning to the Velo, I found some threads on here very useful so thought I would post this to help anyone else going down this path...

    From - Crossfire 2 129 ~1.7
    To - Velo 111 (500HMA) ~1.95

    I also have a couple of jumps on a RAGE 107.

    The 1st Velo jump was from altitude and I was in the saddle by 7K. I followed the same sequence as on the Crossfire i.e. don't look up. don't fight it and go with the flow. The snivel was longer than the crossfire and canopy hunted L & R but opened pretty much on heading, the slider came down slowly and stuck halfway but cleared with a couple of pumps on the rears. Canopy handling was divey & fast as expected. Recovery from dives was very efficient and effective, but the dives are so aggresive that it still eats a lot of altitude, you definately dont want to be in the corner on this!! 1st landing was straight in with no wind at all (1500' elev) no additional induced speed and was no drama's with plenty of flare to bleed the speed off.

    The other 5 jumps all had similar openings, the slider came down mostly unassisted but slowly.. Two of the openings had 180's (half line twists) but these were no issue to deal with. I was told a technique of grabbing both sets of risers and pulling them apart and this seemed to work pretty well.

    The other landings were all 90's from brakes initiated from 470'. Riser pressure built quite quickly and harness input was effective. Oversteer was very noticable compared to the xfire (which had none). Recovery always needed some input - not due to turning low, but I suspect that I was not producing enough speed from the 90 for the canopy to plane out to level under its own steam... it was definately moving though!!

    Overall - a fantastic canopy - I have a totally renewed love of flight!! I am looking forward to exploring what it can do as the jump numbers build. The openings were twitchy and 'exciting' but I had been well prepped for that so I actually found them less eventful than I had been expecting - so far. The openings were however very long and snivelly, even compared with the XF - I do feel that a smaller slider might be beneficial but at the moment, I don't feel the need to go down that route.

    Oh - and I know I'm at the bottom end of the wingloading but I'll be happy enough on this for the next season or so before considering taking it up a notch.

    Hope this helps if you are thinking of going down the X-braced path!

    Paul.



    I found that as I got more jumps on my HMA 500s my canopy's "great" openings decreased in consistency and I have to use the risers more. My VELO 111 is a DOM 2003 not sure if that has anything to do with it. I'm on my third HMA500 line set and its happened with each so far. I also make sure there are no twists in my steering lines.

    If you relax during the opening too much, it will spin up - at least mine does LOL. I spent 7K kicking out 7 linetwists on a night jump when I opened at 11K. So I guess just watch out and don’t treat it as an XF2 during openings to much? I never flew my XF2s in the opening stage as much as this canopy. 700 jumps on XF2s Just under 1000 on my VELO.

    Nice write up - You'll love the transition. Its a fun wing!

    THANK YOU for making my very first Freefly pants!

    The quality is top notch and I can't wait till I get to wear them at the INVASION!

    The colors match my rig perfectly.

    I know it's the second time around because I couldn't measure myself worth dog shit but you stood by your fit guarantee and I couldn't be happier.

    well done!

    Hi Guys

    interested to know what type of exit separation you leave between bodies when most of the load is doing a HP flocking dive....?

    Clear & pull, out the bag, canopy inflated or other?

    interested....



    Probably matters a fair bit about exit order and size more than seconds of separation. Faster canopies have to open higher and come down to the target canopies. If everyone has the same canopy size I would set a base lower than your advanced canopy pilots and then let the flock develop from that regard. The base should fly a predetermined predicable path that will allow pilots coming in from above pick up the formation.

    It’s much easier to bleed altitude then to hold in brakes and get back up.
