  2. I think it is the MC1-1 canopy, just prior to the MC1-1B that came out in 1976. The B version added the anti inversion net, this one does not. But the vent cap is throwing me off.
  3. Your statement of the annual repack per PD is correct, but it also says "Currently, up to one-year repack cycles are authorized for Performance Designs reserve canopies when cared for properly. But it also says in the next sentence, You must use the shortest repack cycle of the your country’s applicable legal requirements, harness/ container manufacturer’s requirements, and AAD manufacturer’s requirements. With that, in the USA as per the FAA 180 day repack cycle, if 40 blocks were marked on the data panel, with no reserve activations, assuming it got packed every "180" days would be just shy of 20 years, not 40... Not saying you're statement is incorrect, but a new inexperienced rigger may read your statement and assume without further review that the FAA now requires an annual repack and not every 180 days...
  4. I have always referred to the article below when adjusting tension on the bobbin. Seems to always give me a good starting point. http://usapr.com/files/Posts/1/bobbins.pdf Your top and bottom tension look good, it also depends on material thickness. Since your sewing with two layers of 1000 denier corder, you may always be able to "see" either the top or bottom threads on the opposite side. Ultimately you would want both the top thread and bottom thread to meet in the middle and not be visible, but material thickness plays a great part in that.
  5. Could it be the difference that the OP has TY8 risers? All the photos on UPTs page are with TY17…Just a thought.
  6. found it...http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CB4QFjAA&url=http%3A%2F%2Fwww.apf.asn.au%2FArticleDocuments%2F145%2FZP-Fabric_Color_and_Strength_Endurance_06-07.ppt.aspx&ei=g75YVIH0NffbsAStroKoAg&usg=AFQjCNEvKJ2gNXSUYkxzGTX2vhrWnCA2-w&sig2=y7rm1DR4OpZlwUSHY_A_ug&bvm=bv.78677474,d.cWc or if you dont want to click the link, google "ZP Fabric Sunlight Exposure and Durability", it's the first result.
  7. I have it as a power point presentation. It is too large to post here, message me and I will figure out how to get it to you via email.
  8. On the MC-7/T-11 chest reserve, it is the small parachute attached at the apex. Replaced the old umbrella type that was on the T-10.

  10. So, lines were cut below LAPs, then "reattached" using a hot knife and an overhand knot. Looks as if it were partially demilitarized and some one tried some "rookie" rigging as a party favor.
  11. I'm not splitting hairs. It is a 3 ring with no release handle, but it also not a cable loop type canopy release assembly as shown in the photo above...if not a 3 ring release, what would you tell me it is called?
  12. Not true... The MC7 personnel parachute the USMC uses the 3 ring release...
  13. What you're seeing in that photo, isn't a "split" in the brakes from the canopy, you're seeing the 5 separate sections laced together. The brakes are attached normally.
