- Marty's already answered you with a "yes, it's non-elastic," but he didn't
- really clarify how this is done (at least on the kites I've seen).
-
- A length of line (kevlar or otherwise) is sewn onto the leading edge, extending
- quite far up the edge. It is done with plenty of line leftover at the bottom.
- This bottom line is then pulled tight and wrapped/fastened in one way or
- another around the bottom of the spar. I think on of the big advantages is
- that the stress is distributed much better along the leading edge instead of
- concentrated on that little hole you've made (and probably pounded a grommet
- into) at the very bottom.
-
- As far as I know, the JordanAir Pro was the first kite to use this idea, though
- I could be wrong. Dean Jordan doesn't use nocks on the Advantage Pro; he
- uses nylon wire ties stuck into the end of the spar, putting the line through
- the tie and then running some half hitches to further fasten the line.
- An end-cap is then pushed over it. The AFC Pro has the line wrapped around
- a nock, again with an endcap over it.
-
- The original Tracer used a different technique, which Skyward called "active
- frame tensioning." The kite has a line sewn into the trailing edge; the loose
- end of the line is then tied into a loop and slipped over an arrow nock. The
- biggest problem with this is that as the sail stretches, the knots will have
- to be re-tied. This isn't _too_ big a deal; the last time I had to adjust
- my Tracer was in August.
-
- The Tracer uses 300 pound unsleeved spectra; I've never heard of it breaking.
- I believe the Pro uses kevlar, which is far more convenient for the half-hitch
- wrapping/fastening technique because it's less slippery.
-
- The latest version of the Tracer (and the version that will be manufactured
- and marketed by Skynasaur) still has the line in the trailing edge, but also
- has a bungee in the traditional spot. I've no idea what this is supposed
- to do for the kite.
