indyz 1 #1 July 10, 2002 Alright, I just bought a rig that will fit a Sabre 170 if I pack carefully. I've put a few jumps on a Sabre2 170 and a Sabre 170 and decided I liked the original Sabre better, plus I saw gobs of used ones for sale. Now somebody has put the idea of casual CReW in my head, so I was taking a look at Triathlons and Spectres. I checked the handy PIA canopy volumes chart to see if the Spectre 170 would pack small enough. The chart lists Sabre 170 volumes as 451, 445, 397 cubic inches for an average of 431. It lists the Spectre 170 as 416, 455, 424 cubic inches for an average of 431. So whats up with the variations? Canopy wear and manufacturing differences? And will the Spectre fit in my container (sorry, I don't have the exact sizing info yet)? Quote Share this post Link to post Share on other sites
PhreeZone 20 #2 July 10, 2002 A Spectre 170 will fit in any container that will hold a Sabre 170. Depending on the container... it could hold everything from a 170 to a 135. I tossed a Lighting 176 (packs larger then a Spectre 170) in the same rig that held a 120 Stiletto. The pack volunme on the Spectre will probally be just a touch lower then a Sabre's. Toss out the high and low numbers on that chart and look at the middle number. See the Sabre is larger then the Specte. 7 Cells usualy pack smaller then 9 cells of the same size.Yesterday is history And tomorrow is a mystery Parachutemanuals.com Quote Share this post Link to post Share on other sites

Depends on where it was measured, who did the measuring, what the weather was like when it was measured, manufacture dates of the canopies measured... there are a lot of variables, some that can't be explained. If you can put a Sabre 170 in that rig, a Spectre 170 should fit fine. Quote Share this post Link to post Share on other sites
ernokaikkonen 0 #4 July 11, 2002 >So whats up with the variations? See this: http://www.pia.com/piapubs/TS%20Documents/ts-104.htm Poynter's manual has also a chapter concerning canopy volumes. In short, measuring the volume of a bunch of fabric and lines isn't really an exact science. The method is explained at the document in the above mentioned URL.
