Prism has a small amount of replacement nocks available but they have arranged to have more expressed in ASAP.  If you need a replacement let me know or email Prism and we will get you taken care of.  At this time given the inventory on those nocks they are aksing that you only request replacement of what is missing and once they have received more you can then get spares.
Spoke with Mark this morning about this issues.  He will be making a video available online shortly that shows how to tie the nock on (btw ... a copy of that video was also sent to the factory).  The knot they use is a clove hitch.
I just double checked mine and it is indeed a clove hitch and even after tensioning and de-tensioning 50 times (at least) it is good and snug.
Those of you that sent emails to me with your concerns/issues I have forwarded them along to Prism.  Also Prism is reading the forum to monitor the issues.

The tension line was coming undone from the nock and the nock was going AWOL.

As Larry put it:
"When you assemble the kite and have occasion to check it out on the ground, be sure leading edge tension lines are secure to the nifty plastic end caps.  If they're not, the cap can slide off easily.  From experience, finding one of those in grass is, for all practical purposes, impossible. "

I put my glasses on and really looked ours over yesterday..................It seems ours is tensioned from the factory very evenly, not too tight and not loose..........It is indeed a clove hitch and it seems (probably) that some are going to be right and some (maybe) not tied properly...........Can't see how it could come loose without manipulation on my part Wink

This knot business is always confusing.  I probably should have been a boy scout when I was young.  Sad

Based on the pdf does two half hitches = one clove hitch?

Not the way I understood it (think the PDF is mixing terms).  Half hitches the knot goes around the "standing" line.... Clove hitch the knot goes around the object you are tying too.  See here

Apparently I wasted away too much time in the BSA with frozen eggs, undercooked meat, night time sledding, wildly unstable boats, and various combustible/explosive/projectile activities.  Sad

Steve, received my 4D today in great condition.

Luckily I have been checking the forum and found that the knots on my end knocks were only one simple clove hitch which wasnt secure at all.

I simply re-tied the end knocks as per the 4D pdf. No issues now, just thought I would post to enable Prism to be aware that the QA around the end knocks seems pretty wide spread.

cheers

A drop of hot glue on the LE rod (then slide the nock on) will keep it there, and allow it to be re-purposed if needed.

Now that I have the knots redone on the 4D I am ready to take it out in the real world.

Another unusual thing (at least for me) is the center T.  The spreaders do not stop in the center but go all the way through.  Other kites I own have a stop or use a male/female set up to keep the spreaders from going through the T. 

Should there be a stop to hold the spreaders in place?  Since the frame is somewhat non rigid will the spreaders pop out of the center T during flight?  I am a little concerned about a sail puncture on its maiden voyage.

I haven't had anything like that happen. the LS have the marks for depth so you can be sure to keep them even. Mine are a pretty tight fit though...

I don't think they'll pop out. There's some tension on them with the standoffs in place and I feel that will hold them in.  I did notice the center T was loose in its fitting and could slide right or left, and I assume all the way out. I just put some CA on it.  Problem solved.
