billvon 2,396 #1 June 30, 2004 I am in the process of relining a Safire 1 129, and before I cut off the old lines I compared the length of the new lineset to the old one. The new lines were between 0 and 3 inches _shorter_ than the current Vectran lines; opposite of what I would have expected with Spectra. The outer lines were about the same length; it was the center lines that had the new lines significantly shorter than the old ones. Has anyone seen how Vectran behaves with wear? Might you actually see that sort of elongation? (BTW I have email into the mfr. to see if there was a trim change or anything.) Quote Share this post Link to post Share on other sites
skycat 0 #2 June 30, 2004 Hmmm....Derek's vectran lines on his VX with LOTS of jumps were the same length as spec. I wonder if they either sent you the wrong lineset or the lineset for a safire2?Fly it like you stole it! Quote Share this post Link to post Share on other sites
Hooknswoop 19 #3 June 30, 2004 You probably got the Safire2 line trim, which is different than the 1's trim. I haven't ever seen any type of canopy lines elongate over time. Derek Quote Share this post Link to post Share on other sites
billvon 2,396 #4 June 30, 2004 >I wonder if they either sent you the wrong lineset or the lineset for a safire2? That's what I'm thinking. Not that that would be bad, if the lineset is the only difference between the 1 and the 2. Quote Share this post Link to post Share on other sites
Hooknswoop 19 #5 June 30, 2004 QuoteThat's what I'm thinking. Not that that would be bad, if the lineset is the only difference between the 1 and the 2. Line set and how they are measured are the only differences. Have a '1' and want a '2'? Get a re-line and re-mark the size as 7% smaller. Derek Quote Share this post Link to post Share on other sites
Chrisky 0 #6 June 30, 2004 Icarus did it! Upgradeable canopies! Get the new Safire "Service Pack 1" now to update your canopy to Version 2! The mind is like a parachute - it only works once it's open. From the edge you just see more. ... Not every Swooper hooks & not every Hooker swoops ...

masterrigger1 2 #7 July 1, 2004 A Safire I and and a Safire II are totally different. The line sets are not even similar! Derek, I do not know where you came up with the 7%....!! If you guys have any questions, please call! I need to dispell this here and now before someone actually thinks that they can put a Safire II lineset on a Safire I and order the same. This is where mis-information could kill someone!!!!

Only mod I made was to the brake lines; I tried to follow your changes by shortening the inside two brake lines the proportionate amount. (Also lowered the cats-eye the same distance so as to not affect overall stowed line length.) It will be interesting to see how it flies. The next canopy I'm getting will be a Nitro/Nitron. I'm sick of having to bartack all these lines. (or to be more accurate, sick of sending Amy down to Otay to bartack lines.) Quote Share this post Link to post Share on other sites beezyshaw 0 #15 July 5, 2004 Vectran does elongate over the life of a lineset, typically about an inch. But it seems to do so fairly evenly, which keeps the overall trim at a very acceptable level. HMA, or Technora, that we use on our canopies seems to elongate just a little bit, much less than vectran does. Both of these fibers keep their trim very nicely compared to spectra.
