  1. Manufacturers are now all offering "Contrast Stitching" on containers, binding etc. because people like the look. So they are already doing this to a certain extent and charging a mark up for the extra effort. As for military requiring contrasting harness stitching. They aren't going to care about aesthetics and manufacturers will do whatever is necessary to maintain those contracts.
  2. I have no clue about the document you listed so total speculation here. But it could possibly be due to incidents/accidents being caused by forgetting to sew a harness after hot gluing. Rare but has happened (even in recent years) but it couldn't happen if it was never glued in the first place. I seem to remember hearing that some military are now also requiring contrasting harness thread for the same reason. When was that document last revised?

  4. I recently hit them up for information regarding line trims for an old Chute Shop Hurricane 135. Got an email response the same day.
  5. I second RockyWoods and buy lots of materials from them. But I am not sure they have the PC style Marquissette (I order mine else where). They definitely carry No See Um Mesh though.
  6. I agree. This is a sore point for me too. I would also include any sport rig that the manufacturer has decided they will "No Longer Support". If they don't want their old gear out there anymore then they should step up and issue an AD. Instead they are trying to dodge liability by dumping the onus on the field rigger.
  7. The OP will pack smaller than the LPV. In my experience the LPV offers the least bulk reduction of all the low bulk reserves I have packed. As a side note, the Icon sizing isn't great from my experience and I wouldn't trust using their chart to confirm fit on extreme ends of their scale.
  8. I suspect it would go along the same lines as AADs. If it's not TSOable then simply insist that it can't impede normal reserve function.
  9. I feel it is important to add 2 additional comments on design differences so that people don't simply walk away with your 20lb vs 40lb statement. 1) The Javelin RPC doesn't need to push past all the flaps that Vector/Icon/Mirage etc do, making its job easier. and 2) The Javelin RPC also stands taller than other RPC designs giving it launch benefits that I am not smart enough to quantify.
  10. 1000 jumps is many many years for some jumpers. To claim his product won't "Cut It" because it can't achieve some random number is just silly. What Df8m1 should do is say that his unit will require battery changes when "prompted" by the control unit. That way he won't be judged against some arbitrary metrics no one else is held to.
  11. So there is the M2 apparently. I am not going to use that as any Standard Bench mark, especially considering it's relatively short field history (I will wait until one lasts its 15 years 1st). Cypres still has a service cycle, it's just left to the user to decide to maintain it or not. And guess what they do at the 5 year cycle, check/change the battery. It even lists "Power supply:...........................................................service life warranty**" And guess what the "**" is. "** If maintenances have been performed within the scheduled time frames." Vigil 1 had a 10yr battery and look what happened there. They had to run a trade in program because they couldn't get the batteries any more. Vigil 2 also had a 10 yr battery but guess what, Any unit more than 8 years old will automatically get a battery change if it is returned to the service center for any reason. And that doesn't even account for the "Expect 5yrs or 2000 jump minimum", stated in their manual. So Airtec doesn't state a life limit, A.A.D. states an expected minimum of 2000 jumps, and Mars states 15 years or 15000 jumps which at this point remains nothing more than marketing. There is no "Industry Standard". His point is invalid. Period.
  12. Well he definitely won't be able to "cut it" if you simply go making up your own arbitrary "Standards". Please feel free to point out what manufacturer states 10,000 jumps to be an expected "Standard" battery life.
  13. https://www.vigil.aero/history From my memory Vigil 2s started around SN:8000 and Vigil 2+ SN was around high 30-40000. Not sure from memory what SN the Cuatro kicked in.
  14. Something else for you to consider would be your location. Your profile suggests you are located in Sydney. I would be willing to bet that the vast majority of Talons in Australia were built by Parachutes Australia who are conveniently located in Sydney. Of the 3 rigs you mentioned one has local support, just saying....
  15. A side note to consider, extraction problem or not, pulling immediately out the door is begging for line twists. Even if you solve your extraction problem you should still consider taking a longer delay to generate the airspeed necessary to lift the bag quicker and cleaner than a 2 second delay will provide. P.S. I jump an RSK 1 and an RSK .5 and have found that overly tight configurations will cause the hesitation you are experiencing. Something I have noticed to be beneficial is to ensure your closing loop is tight, the tighter the better. This will keep the canopy compressed nice a neat inside the container until the pin is extracted at which point the container will relax some making it easier for the bag to lift out.
  16. Does anyone out there remember a little thing called "Google"? A quick search turns up this: http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgTSO.nsf/MainFrame?OpenFrameSet Seems like a good place to start. The Airforce Reserve is not listed among PAs other TSOs.
  17. I don't know about "peer reviewed" but there is a long list of credits in the manual the Poynter gives recognition to.
  18. You might consider Parachutist or Blue Skies Magazine.
  19. I'm confused. You asked for opinions on a big drogue to slow you down with heavy customers. Now you are complaining because you can feel the larger drogue doing its job?
  20. 9 cells support the weight better than 7 cell canopies of the same size (due to increased structure) giving them better flight performance and flare power. Also a number of popular tandem reserves were at one point a tandem main before being designated as only a reserve.
  21. Try using Google. It has lots of answers :-) HMA is High Modulus Aramid. Technora is a brand name of aramid line just like Spectra is a brand name for polyethylene line etc. HMA offers reduced drag due to it being a thinner line than traditional Vectran lines, although some newer designs of Vectran braid are simliar in dimension to comparable HMA lines. Traditionally I would expect Vectran line to outlast HMA although some coated HMA lines are very resilient. It is not that HMA is "prone" to spontaneous failure. It is that once it starts to appear visually worn it's near its end of useful life. Vectran on the other hand can look like crap for a long time before it finally gives up.
  22. Yep. Clearly pocketed and restrictive to deployment.
  23. A little research today revealed that the Vector 2, Talon 2, and Racer manuals all say to rotate the DBag. No pocketed corners in sight on those old things. So the concept clearly pre-dates pocketed corners. The Talon manual even goes as far as to say "FAILURE TO PLACE LINES TO THE BOTTOM OF CONTAINER COULD RESULT IN A PILOTCHUTE IN TOW". So that leads me back to the leverage argument. Of course I could have just made a phone call and asked instead :-)
  24. Absolutely. The correct orientation of the bag gives the PC the advantage of leverage to rotate the bag upright breaking the friction before lifting the bag. I'm not sure this is correct. If it were, Sunpath would greatly prefer bag-grommet-to-reserve-bulkhead/bag-mouth-to-BOC for all its models, including those whose manuals recommend grommet-to-pin. You can't argue with physics :-) Levers have been working for 1000s of years :-) You can of course argue the necessity of that leverage. Can you please link the manuals you are referring to? It may very well be a concession they have made for their own reasoning (the Aurora doesn't count). The Javelin manual on the SP website clearly states "rotate the bag". Another easy way to tell that your DBag isn't meant to be packed grommet to pin is simply the size of the bag in that configuration. Bags are built to fit containers, changing their orientation will mean that the bag dimensions no longer match the container dimensions. If the depth of the bag is greater than the height of the side wall then packing it grommet to pin is obviously not the way it was designed to be packed. Square peg round hole. Edit: As you noted, this has become more of an issue as containers have become more compact with pocketed corners etc. I have also noticed that containers with higher side walls and more rigid boxed in dimensions suffer more here than softer containers with shallow pack trays.
  25. Absolutely. The correct orientation of the bag gives the PC the advantage of leverage to rotate the bag upright breaking the friction before lifting the bag.
