skybytch 273 #26 March 1, 2004 QuoteI've always rolled the 8 outside cells (4 on each side) then pushed them into the center cell.....I've heard this referred to as "stuffing". Think about how your canopy opens. Center cell catches air, then the next cells out, etc. Those cells you have stuffed in the center cell have to come out before they can inflate, right? Seems to me that they are likely putting some stress on the outside ribs and topskin of the center cell as they come out. Enough stress repeated enough times and something's gonna give. Don't stuff. Or do, just be sure to call me when it blows up and you need a new main. Quote Share this post Link to post Share on other sites
PLFKING 4 #27 March 1, 2004 QuoteDon't stuff. I'm not stuffing, I'm pushing.....these guys confused me with their rigger terminology. I'd never heard of actually shoving the canopy into a cell opening. QuoteOr do, just be sure to call me when it blows up and you need a new main. I remember.....Lightning, loaded @ 3.1:1.

atsaubrey 0 #28 March 1, 2004 Iwasnt saying I wouldnt come over the hill for some education. Just figured I bette throw in the "i cant jump there" thing. I have been asking to learn/be thought for quite awhile. If the offer still stands I will be over when ever you like. Send me a message and we can set it up. I already learned how to propack, but have yet to learn to flat pack."GOT LEAD?" Quote Share this post Link to post Share on other sites
mjosparky 4 #29 March 1, 2004 QuoteTSO 23D will let the manufactor certify the contiainer or reserve for any weight/ any speed that they want to choose. Sunpath choose 300 pounds and so did Sunrise on their sport rigs. TSO 23c and 23b have 255 pound limits on them and airspeed of 120 knots. Jumpshack and RWS use 23b on all their sport rigs. That brings up the question of what is the reserve rated for? The numbers you have are not exactly right. TSO-C23b and TSO-C23c or different and have different weights and airspeed. TSO-C23b requires that parachutes meet the performance standards of NAS-804, PPM Vol. I, page 19, and certifies in Standard, 150 mph, and low speed, 130 mph. The standard category must test to a load of 5,000 pounds and the low speed to a load of 3,000 pounds. TSO-C23c was short lived and tested to the standards of AS8014A, PPM Vol. I, page 21. TSO-C23d uses the standards of AS8015B. They have minimum weight of 264 lbs. and minimum speed of not less than 180 KEAS. For a tandem rig the minimum weight is 480 lbs. and a test speed of 210 KEAS. They can test higher if they want but can't pick any number they want. RWS placards their rigs as TSO-C23b, but you can bet Bill tests to the standards of AS8015B or higher. Regardless of what the reserve is rated for, the assembled rig is only rated to the lowest rated component SparkyMy idea of a fair fight is clubbing baby seals Quote Share this post Link to post Share on other sites
quade 4 #30 March 1, 2004 Hey Michael! Wanna teach the kid to flat pack a hugemungous military type canopy? I was going to show him how to PRO pack, but I think I'd bow to the master of flat packing.quade - The World's Most Boring Skydiver Quote Share this post Link to post Share on other sites

billvon 3,107 #32 March 1, 2004 When I flat pack I'm usually packing for fast openings (i.e. BASE) but I have noticed that the nose can get pretty easily messed up when flat packing because it's the part that contacts the ground when the "stack" is complete. Often I lift up the pack job before I wrap the tail and inspect the nose. I usually make sure it's wide open, but in your case you could fold it over once, or fold both sides of the nose towards each other (but not _into_ the cells.) Five years ago I would have suggested you find a tandem packer - the older F111 tandem mains tended to open hard, and there were a lot of tandem packers with PRO-pack tricks that tamed even the big 520's. Nowadays tandem mains are a lot more snively. Quote Share this post Link to post Share on other sites

Nowadays tandem mains are a lot more snively. I think the reason big F-111 type canopies and all large 7 can open hard is the way they are made. The top skin does not drop over the front of the cell and the cells are really deep. If you pack the 370 in question following the manufactures instructions the nose is not on the ground, you do not "stuff" the nose and you will get nice soft openings. Remember these canopies were designed to open and 25.000 feet at a 150 keas and carrying a 100 pound ruck.

quade 4 #37 March 1, 2004 Um, are you questioning Michael Owens (about flat packing a military type canopy of all things)? Seriously, I think even Bill might bow to Michael on this one.

I don't think we can get the hook high enough, this thing is 28.5 feet by 13 feet. Thirteen feet is 3 feet higher than a basketball hoop.
