    ...once the last is out of the door...



    This is not even required. It's scoring formations in working time, and working time starts when the first jumper leaves the aircraft.
    Hard to get a clear presentation though, when stuck in the door...:S

    .....Oh, and a "cutaway sensor" could be something as simple as a 2-wire connector with a shorting link that is tied to an RSL ring, for example. Very simple, no moving parts.


    THE most common failures are with connectors >:(. A pin sliding in and out of a socket is most definitely a moving part.
    A solution to this problem may be a small magnet and magnetic field sensor.
    Still I don't like this idea, too many fault trees.

    Tell me more,

    Can you compare the Mambo with either the XfireII or K ?



    The Mamba is targeted at the same audience as the canopies you mentioned. So it has similar characteristics. I've been flying a Samurai 105 before I tried the Mamba 111. I liked it very much; a fun, versatile canopy.
    Openings are soft, but keep your shoulders level or it will dive. Possible to stay up there or get down quickly. Maybe not as ground hungry as a K, still easy to swoop.
    See also the june 2005 Skydiving magazine article.

    The canopy you tried, the Mamba 111, or "New main" as it was called then, is one of our team canopies (Norwegian 4-way team, Arcteryx). My teammate lengthened the steering lines only a few days before you tried it. This will probably explain why you felt the the flare range was a bit "low".


    Ah, now I understand. B|. I knew you guys were jumping these. Arnold was scrambling that Friday to get them to the post office to get them back to you guys.

    I have several hundred jumps on the canopy and the flare power of this canopy is excellent.


    Yes it is. Never had a problem with it and it just got better with more speed. Thanks for the opportunity to try it. It was real fun ;).

  13. Hi,

    I'll try to aswer some of your questions. The airlocks make no difference in glide performance, only in stability in unstable air (turbulence). The pack volume of an airlocked canopy is about 5% more than a non airlocked canopy. That has nothing to do with flight characteristics. So no, use same sized canopy. Hopefully this sheds some light on the matter.

    But from your question and your profile (400 jumps, Vision [email protected]) emerges a not so pretty picture. Looking at the Aerodyne website, this canopy is not right for you in several ways. First of all it's intended for Advanced canopy pilots, 200 jumps a year won't make you that. Second the Advanced scale starts with a wingloading of 1.6, which may explain you finding your canopy flying like a dog, loading it at 1.29. Each canopy design has it's upper and lower limits. You are experiencing why.

    So looking at the Aerodyne product list you'll have more fun with a Pilot 132. Yes same size, but loaded within design specifications, which can make all the difference for flight characteristics.

    Qs....

    1) how much bigger does an airlocked canopy pack (how much bigger does a Lotus pack, than say a like sized stilleto/sabre2, and how does it fit in your rig?


    From the Big Air Sportz Owners Manual (can be found online):

    The pack volume of our canopies is approx 5% larger than that of a similar sized canopy without an airlock system. Choose your container based on the standard for the size canopy, and adjust your closing loop accordingly.


    From my experience with the Samurai 105 this is correct.

    2) Where did you buy your Sam/Lotus and how was the service?


    I was lucky enough to get, after a long wait, my hands on a second hand Samurai. Contacted Brian about somethings, got excellent replies.

    3) Long-term reviews and impression of whole experience


    In short: very good. B|

    I was just wondering what the manufacturing differences were



    Probably there isn't any.
    The thing is that it's not a 100% predictable process. Therefore a tape reel may be produced not living up to 'Excellence' standard. To improve the factory yield they sample test the reel, and if oke but not of Excellence quality, package it as Premium. :ph34r:

    Bottom line, there's nothing wrong with Premium tape, but it's just not Excellence. And if your lucky they have a series of good runs and package Excellence as Premium anyway. :P
    Mind you: all this is common practice, but not confirmed in this case! :)

    At the time it looked like a lineover, and it definately looked like something I ought to chop whatever it was, which I did, and that's the most important part :)



    May I add kudos to the jumpmaster for spotting from this C-47 so that the main and freebag landed right beside the club-bar. Well done Oortje! ;)

  21. Not being a CReW dog at all I still had a wonderful time. I tagged along with my girlfriend to enjoy a week of sunshine in Spain, and act as personal packer. Even made a couple of video jumps, with some FS4 and 1-on-1 CRW. All in all I really enjoyed myself.
    Thanx to Chris and Dave for their excellent debriefs (even I learned something about CReW!), Gauda and Cookie for getting all the ladies out there and Richard and Juli for all their support from CPCB.
    Don't forget to check out the CPCB website, which hosts great photos and footage from Vincent and Gustavo.

    Here's a nice example of pushing too early for speed before that mentality is in place. I'd like a name for this one.



    I'd call it the Axe. Notice the cat being the handle and the sidebody being the blade?

  24. First and foremost: Relax :P

    How do you expect to fly your body when it's locked into hard arch? You can't. Since you're able to walk up straight (save assumption, I guess :$) your body doesn't really need training, your mind does.
    Take a moment to ask yourself how you really feel on a jump. Excited, for sure, but what are your worries? Stability, altitude awareness, opening? When do you feel this, on the ground, before exit, in freefall? Confront these worries, learn to handle them, this will relax your mind. Then you can turn your attention to flying your body.

  25. Hello Wayne,
    My guess is you jumped from a left hand door? Probably the front floater and/or diver pushed out a little harder on exit than the others. This gives your formation the momentum to turn anti clockwise. [:/]

    To solve this in a star you all have to turn really hard, using your legs, towards a clockwise turn. This will stop it. I don't know if you master flying with your legs: this is a good reason to start doing that! ;)

    Of course it is always better to avoid this situation than to solve it. This requires a bit of thinking about your exit. You know what the formation looks like outside the door. So you know where everyone has to go from his/her position in the door. Plan your jump from the door accordingly. :)
