  1. Just out of curiosity, Can you post a picture with someone showing what the head position is when wearing this? The Norwegians posted a similar teardrop helmet on this forum and the head position was pretty much looking forward with the tip of the helmet resting on the rig.

  2. On your point about putting "tension", aarthus, is this possibly not because of the inlet design and sizing?

    The small inlets on the arm and the leg have to inflate the suit. The inlets are parallel to the surface of the suit and have to fill a lot more volume. There are also more places on these suits(can comment based on the S-fly expert I flew) where the air can escape from and that causes the inlets to be even less efficient.

    When the relative wind is at a small angle, these inlets will perform poorly.

    The flyer has to compensate and tension the suit. The guy that flew the Pro-fly for 5:45 gets major kudos.

    These are still pretty fun to fly. As the other guy said, if they only made them in M++ and L-.

    Vesa is jumping at Z-Hills this week ... come ask him yourself!:)

    Visa :P , no?. Met him in Norway 2007. Awesome guy!!

    Visa = Rocket Man
    Vesa = BadAss Wingsuit BASE guy.

    oh Ive never listed the Apache, Ive been working on it for these 2 years, I used it for the 71 ways in fact,
    I'm not a wingsuit baser so I'm not the expert here [one day, I have 2 BASE jumps] but it seems to me that being able to reach up to your toggles immediately and to get out of the legs in 2 seconds would make it an attractive suit for base, the wing size is a different matter of course.
    I have done some base pouch's, currently its a two pouch system with a bigger one over a smaller one, and it goes across the butt for an easier pull, slightly angling down.

    I confused the website with the Order form. Apache is on the order form.

    May I request that pics of the same person wearing the different wingsuits or pics with suits placed one on top of the other in your line up be available on the website? That makes it easy for people to know roughly how the suit area is distributed.

    Our Belgian friend Nico basejumped a raptor/mach1 (it was a slight custom suit, so not sure which one it was) but he did note the pull being scary.
    I know he mailed back and forth with Tony regarding (re)location of the basepouch to a more suitable location. Maybe Tony has a few words on this subject?

    Nico is no longer jumping the tonysuit for that reason, and switched to a more recent release from a competitive manufacturer.

    Is this the Nico that posted video a while back? To my knowledge, he is the only guy to have posted BASE video of a Tony suit. I think that suit was called an Apache.

    The tonysuits website does not list that suit as a product anymore.

    Bigger isn't necessarily better with wingsuit wings. In the picture you provided I wouldn't be surprised if the suit would be fairly slow vertically (but perhaps hard to control--think balancing on a beach ball) but its forward speed might take a big hit due to the excess drag.

    My guess is that this suit would be a good glider.

    The Center of gravity of a human is roughly somewhere near the belly button. Higher up for people with a muscular V shaped body and lower down for women and skinny guys.

    The angle at which any suit naturally balances on the 'beach ball' depends on moments of the lift and drag about the CG.

    With so much wing area below the CG, my guess is that this suit would balance head low and thus be easy to glide in.

    I guess that may be why suits like the SM1(lot of arm wing above the CG) work for solidly built American guys but don't work that well for the more slender Europeans(will need a suit with more wing distributed lower down).

    Tony told me he did a couple jumps with them as well, and he also saw the flow quickly became turbulent, the threads pointing forward instead of back. It would be cool if he could post some video if he has any. Tony?


    Don't doubt that for a sec. IMO, Those tufts pointing forward argues the case for having a butt deflector. But that is my interpretation.

    I am really keen on knowing from this CFD study, not on an absolute basis but comparing the results between different configurations for the given model over the same angle of attack range.

    a) the Induced drag and how it varies with wing twist(anti-clockwise).
    b) Flat wing vs a curved wing(spanwise).

    What I think is less important than what can be measured.

    However, on ANY airfoil under any flight condition the lift is the difference between the mean pressures on the top surface and the bottom surface, so you can't ignore one surface and hope to model anything useful.

    Thank you, I could not have said it better. That is my point exactly!

    I would be wary of accepting that video as gospel. Anyway, the Software he has access to can predict the airflow around a wing more accurately than the video.

    I'd be very surprised if off the shelf CFD software can handle the kind of turbulent flow encountered over the top surfaces of a WS. These packages are not designed to do that.

    I'll take your word for what the software can and cannot do.

    The video is showing one configuration( straight arm ) and a very un airfoil like shape. There is also a very irregular edge after the leading edge(stop video at 20 secs)

    Even so, at the end of the video, the tufts pretty much hug the first few inches of the wing.

    Compare that shape to the one here
    here. Seems like the tufts would hug a shape like this a bit longer.

    As for the contribution of the top surface of a properly shaped wingsuit wing to lift, what do you think?

    This little movie is quite telling in how quickly the laminar flow leaves the wing and it becomes one huge turbulence on top of the wing. Maybe this will help you in your research.

    To the original poster,

    I'll help in anyway I can, just ask.

    Would be cool to see what you find out.


  • Agree that the complex rules are probably not the best way. These tubes are they soft? If so won't they blow back making the distance they represent between two jumpers depend on glide angle? Still some length based on formation size and observed glide can be predetermined.

    Don't drop your tube :)

    On the 305 (and probably the 405) you can change the settings from the "smart recording" option to the "every second" option.

    Yeah, all the Garmin GPSes I have used have the smart recording feature. I preferred turning on 'every second' option.

    I used to have the setup shown in the pics.
