Lineset questions Can't Post

Hi,

I have a safire2 169. Is the type of lineset usually stamped somewhere on the lines? If not, what is the best way of telling the difference between say vectran lines and spectra lines.

Are certain canopies always manufatured with the same lineset type?

And finally, is it straight forward to swap main canopies on a rig or is it soemthing a rigger would have to do? How much does it cost approx?

Thanks.

Icarus recommends the Vectran lines, that's what my Safire2 169 has. Pretty simple to tell the difference in newer canopies, spectra is white, vectran is yellowish.

Swapping a main canopy isn't difficult, but I highly suggest you have a rigger look over your shoulder the first couple times. Wink

I've seen FAR too many mains hooked up wrong in ways that could seriously ruin your day by people that didn't understand fully what they were doing.Unsure

your Safire2 is very likely to have Vectran lines.
if new, those appear to have a yellow-ish color to them, as opposed to spectra being white. When aged, the vectran will look grey.

if in doubt - take the SN and email Icarus for their build spec

Vectran, HMA, Dacron and Spectra (microline) all look quite different ask an experienced jumper or rigger to have a look and tell you.

Thanks for all the info. The picws and link are very helpful as well as the other tips.

I'm 90% sure it's vectran going by the replies and the pics but I will double check.

On a similar subject: does a couple of small patches on a canopy (say a 150) affect its performance much? How does it generally affect it's value when selling?

If done properly, patches shouldn't have any effect on a parachutes performance.

I'll let Paul talk about the resale value.

The above recommendation about having a rigger supervise is excellent.

However, there is a variant of this task that is commonly done and is relatively easy. Swapping canopies AND RISERS together is much less complicated. I have seen CReW dogs do that several times in a day to match canopies and jumpers (most common when training new pups.) This is also done when "demoing" (test driving) canopies before purchase.

That said.... my only cutaway was due to doing this REALLY fast and mounting the main backwards. (Yes, I know that it is possible to land backwards. Yes, I have seen the photos and award cards for "backwards CReW". Yes, some of you have done it, or would do it. However, the canopy was a Lightning and was smaller than my usual canopy. Prudence dictated getting rid of it rather than attempting to land it.)
