    Just for the record, that's their normal construction on their multi ring harness. I think it's stupid. No one else does it that way. On the other hand it's never failed so theirs that. But I was also astonished when I first saw that design.

    It's build that way, so you can build very short MLW ( as short as 13") for very small jumper and still have enough space for the reserve and the cutaway handles. Other manufacturers use separate pockets sewn over the webbing, to cover the 4 point stitch to achieve the same. They all work fine. I hope user Jeffrey steps in here and tell his story.

    Cheers

    Sandy Reid, Rigging Innovations....
    Velcroless pin covers and riser covers (tuck tabs)



    Hi Chuck,

    Do you know which year Sandy made his tuck tab riser covers?
    The earliest rig having those I've seen is an Atom from '89.

  5. It's probably never the effort of one man when talking about the major players PD and Icarus.

    Was it the same person who designed vx/fx, created petra/lela?



    I can't be 100% certain of that, but during PIA'13 a young guy called Julien Peelman (? spelling ? )who works for NZ Aerosports gave a really cool seminar on canopy aerodynamics. I left the room with the impression that he is the guy behind the Petra, although he never said :" I designed Petra". I don't know how old is he, but I highly doubt that he was a skydiver when VX and FX came on the market .

    I'm also curious now !

    Which should be the smallest canopy to use with a Vigil in Student Mode?



    You should be fine using almost every sport canopy in any size. Just don't turn bellow 1000 ft. I don't think there are many canopies that will descent with 20 m/s on a strait in approach. Maybe very small cross braced canopies with very high WLs.

    On the other hand, I think you can "scare" the AAD even with say 250sq. ft. student canopy if you make some turns.

    So, what decision you are trying to make?

    KAP 3 had 2 modes.:P

    Mode 1) You set activation altitude to 4000 meters, and it will pull ripcord (spring loaded main), after 5 seconds when pin is removed. Pin was usually connected to aircraft's static line anchor point with long line.

    Mode 2) You set activation altitude to (let's say) 800 meters, you can remove pin in plane, it will count down to 1 second, and stop.
    Then you can jump, and after falling below 800 meters, KAP will continue counting for 1 second and pull your main ripcord.


    I hope you don't mind if I correct some info.

    Yes, KAP-3 or PPK-U AAD has 2 modes. Time and altitude.
    In order to use the time mode, you have to set the altitude scale higher than the altitude you will be jumping from. Any altitude higher will do the trick. We were setting them on 3500 m. and 2 seconds for the PEP's. That way, the aneroid will not block the trigger. You can set that timer anywhere between 5 and 2 seconds. Once you leave the plane and the safety pin has been pulled, after the selected time passes, the trigger releases the spring.

    If you want to use the altitude mode, you have to set the altitude scale under the altitude you will be jumping.
    Once you leave the plane ( and the safety pin has been pulled) the timer will start counting down from 5 seconds, but the aneroid will stop it somewhere bellow 2 seconds ( for most units that will be between 1,2-1,5 seconds). Once you pass the selected altitude (ASL), the aneroid will release the timer,and in about 1,2-1,5 seconds, the trigger will release the spring. ( about 36 kg pull force )

    I guess I still have a paper copy of the original manual in Russian if you are interested ;)

    Who did do the first tuck tabs? As I recall Javelin as an example was already using then on their riser covers when Talon still had Velcro riser covers.


    If we are talking only about riser cover tuck tabs, I think the first one was the Atom from 1989. I could be wrong.

    Keep 'em coming :)

    Bill Booth - well that covers 75% of the container you're currently wearing.



    I think you are giving him too much credit. He did invent many things and his contribution to the sport is indisputable, but 75 % ?

    Let me tell you about my rig.
    It's dual canopy container ( he didn't invent that ). I have throw out PC( he invented ), but my PC has a kill line ( he didn't invent ). My PC is packed in BOC pouch ( he was not the first one to put it there ). My harness is articulated and the container has many tuck tab flaps ( he didn't invent ). My reserve PC is spring loaded and it's activated by a ripcord ( he didn't invent ). My reserve is packed into a freebag ( he didn't invent ). The freebag is closed by a safety stow ( he didn't invent ). My main canopy release system is 3 ring ( as we already know, he invented that ). I have a RSL ( he didn't invent ). My main risers are type 17 ( who invented those ). My risers have dive loops and slider locks ( and I don't recall he inventing those )

    I really don't get where the 75% came from!

    Back on topic

    Dan Poynter - 2 pin pop-top
    Stefan Ertler - 1 pin pop-top
    Brian Germain - Airlocks
    Bill Coe & John LeBlanc - Crossbrace
    PdF - reusable soft links
    PdF - reversed risers
    Bill Booth - Spectra reserve ripcord

  12. The title says it all.
    Who invented what? From the curved pin, to the articulated harness. From the free bag to the MARD.
    It could be anything you can think of! Pro-pack, soft reserve handle, dynamic corners....... you name it!

    There's only one rule. No brand wars!

    That said, the guy who invented both now says that one of them was a mistake.



    Bill Booth - throw out
    John Sherman - pull out

    Now you know why the inventor of the throw out doesn't like the pull out B|

    Quote

    That would be the one that gives you an out of sequence deployment every time.



    How come the pull out gives you an out of sequence deployment?

    This question is a trap. Don't answer it!:P

    ETA: To the OP, ask your dad :P

    ***No I don't weigh 245 lbs, I weigh 270 lbs before gear. Im 6'8" with a size 14 shoe if that is relevant ?

    DAMN! I would love to make a jump with you we can have some fun in free fallB|

    Just make sure you ask the pilot for FL150, so you can get 30-35 seconds working time ;)

    To the OP, I second the LockMa suggestion ( if you can get one )

  17. Unless you have experience in packing many stuff into even more stuff, your best shot is fill in your measurement and canopies on the order form and let the manufacturer decide what rig size you should get. Everything else will be a gamble ;)

    It's the same company... What difference does it make?

    .....and im pretty sure even cypress had problems in there early days



    True... What you ( and many other jumpers ) fail to understand is that Airtec is about 200 000 units and 23 years further and they have never had a cutter failure. Unlike every other manufacturer.

    It's OK to jump whatever you want and I'm fine with that. Just don't try to justify it with stupid arguments.

    A friend told me about this Juki machine. This machine is a 2-needle that allows you to lift one needle at a time.



    You don't actually lift one of the needle. What you do is disengage one of the needles in upper position which transforms the twin needle into a single needle machine.
    Once you learn how to use it, you will never look back. It's kinda like when you zig-zag lines on your 20U and then you buy a bartacker B|


    Quote

    PS) I would love to spend about a half hour with this machine just to see how easy it is to use and how the results turn out.



    If you visit us, you can play as much as you want, but from my personal experience, a half hour will not be enough. Then again, I'm not a fast learner :S

    From Mirage Systems:

    "You've got questions, we have answers! Check out the video on how the Trap Systems works; below our Q&A!

    Q: Is there any way to “deactivate” the Trap at all? For example, can I disconnect my RSL when I do a CRW jump?

    A: Yes, we designed it to be flexible to the needs of the jumper and the different type of jumps they may be doing. You have a couple of options with the Trap System:
    1) You can completely deactivate it on any jump by simply disconnecting the RSL shackle from the riser.
    2) You also have the option to ‘set’ or 'not set' the Trap when your reserve is being re-packed. To ‘not set’ it, your rigger would need to leave the Trap Line off and stow the reserve bridle normally (outside of the Trap). Basically just close the Trap Door and forget it. If the Trap Line is left off during repack then your RSL functions as a normal RSL. Standard Mirage RSL lanyards are black and Trap System lanyards are red. If a Trap System has been ‘not set’ during repack we strongly recommend using a standard black RSL lanyard, instead of the red one, to signal that the rig is functioning with a standard RSL.


    Q: Can the Trap System release the bridle if necessary after it’s ‘Trapped’?

    A: Yes. The Trap Line cinches but does not tie a knot. If the reserve pilot chute is creating more drag than the malfunctioned main, then the Trap System will allow the bridle to be released so that the reserve pilot chute can deploy the reserve.


    Q: What happens if the bridle is tucked into the elastic beyond the red line?

    A: If the bridle is incorrectly rigged and extends beyond the sewn circle of the Trap Loop it becomes possible for the Trap Line to cinch underneath the bridle. This would allow the bridle to escape and not be ‘trapped’. If the Trap Line is not able to trap the bridle, then you will have a normal deployment in which the reserve pilot chute deploys the reserve (good news), but you will also end up with damage to the Trap elastic which will need to be repaired (bad news).


    Q: Why is the bottom of the elastic left open instead of sewn closed to form a pocket?

    A: The bottom of the trap elastic is left open to not hinder the elasticity for holding or releasing the bridle. When the bottom of the elastic was secured during testing, the tendency in packing was to overstuff the bridle into the elastic to ensure it wasn’t being ‘pushed out’ and resulted in a rounded lump inside the elastic. The open bottom is easier to pack, easier to inspect, and allows the bridle to be inserted the full depth of the elastic.


    Q: Are you accepting orders for the Trap System?

    A: Yes, it’s an option on our order form. If you have an order in process and wish to add the Trap System, please contact our front office as quickly as possible."



    Well, the Trap guru at Mirage is definitely following this thread :)

    If the RSL cuts off the PC, well.... Game over. What testing was done in this regard?.....



    To my knowledge,no MARD was ever tested in a horseshoe situation.

    Kelly. Any thought to adding something like this to the Infinitys?



    Kelly's RAX is still my favorite MARD by far, and I'm still surprised that he is not using it.

    When I say "my favorite", you should read it as :" I don't really like MARD for sport rigs, but if I have to work with them, RAX is my favorite"

    Thinking of buying a used Atom Classic OO as my first rig.
    Any ideas?

    Thanks!



    The biggest reserve that will fit in is a Techno 128 and the biggest main will be 135-ish. I don't think this size will make it suitable for first rig.
    There's a service bulletin about the Classic regarding the deflector flap and AAD cutter location. If you buy it and your rigger doesn't have the manual, let me know and I'll mail you a copy.
    Parachute de France made some nice rigs but their customer service was awful. Be aware that from Feb. 2015 they will no longer make sport rigs and finding spare parts will become difficult.

    PM me if you need more info

    ***Not sure this is correct regarding this helmet, but with my bonehead guner I got a note explaining how to change the fit of the helmet by heating it in the owen.



    I am not an expert, but as far as I know this is only valid for carbon fiber helmets.

    First read carefully the manual from the Bonehead helmets.

    "The liner is made up of a thermo-formable foam covered in neoprene and fabric, which when
    heated, will soften and can be molded during the cooling process."
