    Here’s what a long WS BASE flight looks like.

    Yes, this flight has been done in Jedei3 a few years ago, then in Antoine's prototype, and now in Aura5.

    Looking at flight profiles for Pordoi, it could also be comfortably done in Corvids, Glider and of course CR+. 

    Have a go on https://next.skyderby.ru/flight_profiles , filter by place/suit/pilot etc as you see fit.

    Back in 2010, 3:1 was huge. What is it now? Have advancements in design and development pushed the abilities to get beyond 4:1, maybe even 5:1? Has anyone gotten some solid data on the glide ratio for the new Squirrel Glider? 

    There hasn't been any measurable advance in sustained glide for quite a few years now. It topped out at 3 point something low, limited by our pathetic body aspect ratio. In the last 5 years there may have been 0.1 improvement, if that. 

    Open Skyderby, filter by suit and see for yourself. 

    Glider is designed for the fastest starts possible, and it glides very well - but that only means at the same sustained L/D as Jedei3 made 5 years ago. If you want even better sustained glide, the only option will be CR+, and the difference between them is tiny, roughly in 0.1 range.

    The only available route to increase L/D is to increase the aspect ratio, i.e. to increase the wingspan beyond the usual wrist as a wing tip. See Antoine Laporte's prototype suit as a step in that direction - he's currently flying better than anything else on the market in BASE environment, with better starts, and with L/D that exceeds all other production BASE suits and roughly matches CR+ on longer flights.

  4. There is a major thread developing on http://www.skycentre.net/index.php?showtopic=22276&st=100 about PD reserves bought second-hand, that on closer inspection show a fake label and signs of tampering/repair/rebuild. So far 3 cases have come up in Russia, and the canopies may have originated from Poland.

    Please be aware of this scam if you buy a cheap second-hand reserve canopy, and be especially conscious about any bulk buyers of expired reserves online.

    bsbd!

  5. The easiest way for USA to help stop Syria civil war: do nothing. Simply stop helping the rebels, and Assad will eventually win.

    The quickest way to save hundreds of thousands lives and stop the war: actually help Assad. Better yet, press Saudi and Qatar to stop supplying hardcore sunni jihadists with weapons and cash, and the war will be over with in a heartbit.

    One can always argue that the same idea applies in reverse, i.e. if Russia and Iran stopped helping Assad, the rebels would eventually win. This is probably true (even though Assad seems to have the upper hand now). However, the result would be the opposite: if Assad wins the war ends. If rebels win, the infighting between them and the fully sectarian war will go on indefinitely.

    This is rather obvious if your priority, as often claimed in mass media, were to save innocent lives. Unfortunately, none of the cynical and evil players of this chess game (USA, Russia, Saudi Arabia, Qatar, Iran etc) care about that.

    My perspective and emotional involvement in this matter comes, among other things, from driving all over Syria a few years before the war. I have particularly enjoyed little bits like visiting dozens of amazing old churches in Aleppo, or buying a bottle of wine in a corner shop and getting a free corkscrew as a present... you know, all the bits that come with Saudi style Sharia.

    I am also a citizen of both USA and Russia, and thus have a rather unique opportunity to look at things from a distance - or else i'd go schizophrenic.

  7. Anybody familiar with math and basic statistics please feel free to comment. Vertical axis is the number of electoral districts. Horizontal is % of votes for a party. Data is from the government election committee site.

    In short, a bell curve is expected for all non-fraudulent results, with its peak around the real % for that party.

    Total for Russia: http://pics.livejournal.com/oude_rus/pic/000tzr59/s640x480

    If you can guess which color is United Russia party, you get a prize. If you can figure out real results, you get an A+ :ph34r:

    Anybody with a proper math background care to comment?

    Regardless of him flying a shorter distance than the others he still showed himself as a fast flyer and the Apache X looks like an interesting suit. Marketing himself as the fastest in the race though is not fair.



    Looks like another old fart just made it official, LOL :ph34r:

    Fact 1: Tony's blog wrote on 14.07.2011, Tony is the fastest in his Apache with 18,37 seconds.
    Fact 2: Frode is official winner of base race 2011 with 29,37 seconds.

    My question is: could anybody please explain me the difference of 29,37 - 18,37 = 11 seconds?



    Different cliffs ;-) As far as i can see, the fastest time in official competition yesterday was Frode's 18.53

    My own ticket has been bought and paid for



    That's where you can stop all this BS ;)

    Your ticket is a freebie inheritance, and should really carry no weight in a theater that doesn't recognize other inherited titles.

    Meanwhile those without tickets get to clean the theater of (and for) the scraps of popcorn you drop on the floor, while watching the show from the walkways. Some will earn their seats eventually, to the bitching and moaning of the free-pass crowd, and that's as fair as it gets in "all people are equal unless they are mexicans" land.

    If they want to come here, do it legally and go through channels just like our relatives did, otherwise stay the hell out of my Country.



    Come in a big ship with a lot of cannons, kill a bunch of locals and generlly take over?

    As opposed to sneaking in tiny boats, using smaller guns and only occasional killings? ;)

    Now post yours.



    Nice flights, quite impressive! I liked this one: http://www.vimeo.com/7103784, nice use of ridge lift, but a bit turbulent indeed! Are you guys making it over the football fields on the other side of the main road? That was our main LZ back in '06. Almost got my ass kicked for spoiling a game with a low overpass once :ph34r:

    Seems like things have changed a lot while i was away... everybody is into proxy, speed&race nowadays. I can see why (distance is boring compared to proxy), but a shame in a way, as new suits took away endurance problems and added a bit more glide.

    bsbd!

    Yuri.

    ok, I'll do it, ive never done a wingsuit base and I dont like pulling low but....hmmm maybe we can get Toby to do it, you reading this Toby, he doesnt like to pull low either, 300 m.



    Somebody has to! ;)

    You should be able to pull at 300m over the village at L/D of 2.9.

    If you do fly at 3.5 you will be pulling at 600m. These numbers assume 200m of altitude wasted for a lazy start, obviously that can be done better.

    Quote

    Heres a question, does the G/R improve with lower thicker air? it sure feels like it.



    It does not. True airspeed (i.e. both vertical and horizontal, proportionally) does increase with altitude, so starting a suit higher up will take slightly longer. Sustained L/D will be the same at any altitude, assuming that you are indeed flying.

    Google, like http://www.stolaf.edu/people/hansonr/soaring/spd2fly/densalt.htm if you want to know why in detail.

    At 3.52 actual and a mere 2.62 required, this must be piece of cake for Tony.



    The graph is suicidal: the red point at 5k mark is impact ;) You need to allow for deployment, say at 100m AGL.

    Also, suits start to fly waaaay sooner. It may be hard to scientifically plot the first few seconds, however multiple experiments show S3/V1 style suits at about 300m horizontal mark 300m below the exit point (as measured by deployment and landing/water impacts from 370m range objects ;)

    Are you flying a V3 already? Any attempts planned in the (your) near or far future?



    Nope, and probably not this season. I took a year-long break from flying, and now got stuck in Scotland for a while. Maybe back in the fall, but won't be current and high-alt season will end by then. Otherwise i'd quietly go and rape it instead of posting here :)

    Sounds like a great challenge..

    Whats the furthest distance flown so far on this jump?



    Not really sure. I made it to the last hill back in 2003 (4300m mark, 2050m altitude) on S3 prototype, and again to the same exact point on V2 a couple of years ago.

    Endurance seems to be the key to make it over the last hill when you are low and tired. I recon if you make it over this point you make it all the way. It's hard to judge exact altitude at such a shallow angle, and you must beware of a weak pull - i almost got burned on the first attempt by using up all of the arms energy and barely extracting PC out of the pouch B|

  25. Yo !

    All this talk about downwind 3.5 glide flights reminded me about a very nice real-life L/D challenge that's still to be conquered:

    Try flying from the Mushroom (Eiger) all the way down to Grindenwald. It's a scenic and intense flight over the rolling hills. You will need to cover about 5000m distance to use all 2200m of available altitude, requiring a measly 2.6-2.7 L/D average depending on how much altitude you allow for a start and deployment. Exit altitude is 3200m, which puts it rather close to a skydive. Wind will not be a significant factor: you have to pick a quiet day to survive. Access is easy, start is safe, and LZs are bigger than most DZs :)

    Plenty of attempts have been done from this exit over the years, and AFAIK the challenge remains. It should be so easy now with the new suits, eh? C'mon, do it, even at 2.9 you'll be a rock star! ;)
