Hi All

I wasn't going to weigh into this debate, but seeing as my name was
used I should put my thoughts forward.
Whatever I say in this post in no way at all is the opinion of Peter
Lynn Kiteboarding.
To the best of my knowledge there were a few 13 metre venoms that did
suffer tip collapse. If this did happen to your kite the best way to
resolve the problem is too pull the third braid out through the weep
holes in the trailing edge at the end of the kite. Fold it over on
itself and sew it down so that it shortens the braid by about 15 to
20 millimetres. Then in the next cell towards the centre of the kite
pull the braid through the small gap in the gauze at the trailing
edge and then pull it out of the weep hole, shorten it also by about
15 to 20 millimetres, this should stop the tip collapse. In my
opinion the rods being a little bit on the short side will not cause
the tips to collapse if you shorten the braid, but it is extremely
important to have them firmly in place so they do not come out of the
reinforced area at the leading-edge. Because I have sold leading-edge
Kite Co which was my manufacturing section I have not got lekite web
page anymore so I am unable to post any photos. If somebody's Kite
did suffer tip collapse you could e-mail me privately and I will take
some photos to show you what I'm talking about. I am in the process
of building a new web page which will be [www.kites.com.au] for Bob
Dawson kites. Hopefully should be up and running over the next
couple of months in time for next summer.
