Lucky for me I was able to fly the 4D most of the day at a local kite festival.

After one particularly LONG session of no wind I went to check on the 4D.  Even though I had retied per the PRISM instruction, one of the nocks was loose, but still attached with one knot.

I recommend you keep a close lookie at this part.

I haven't seen a new 4D yet, so don't know what the fittings look or work like, but is there some reason they can't just be glued on?  With any other kite, if the nocks aren't glued and the bungie or tie down breaks, the nock is usually lost. What's the big deal with this one?

To make it a cinch to put together, Prism designed a clever little wingtip fitting that instantly tensions and de-tensions the leading edge with no knots to fumble with.

at least this was the idea

Although I like the 4D the nock seems more like a gimmick than a revolutionary concept.  If I loose them I will probably go to a traditional fixed nock as a replacement.

I really like how the nock works because its so quick and easy to tension the LE.  But  I don't trust the clove hitch or any other knot to hold.  Mine came tied in clove hitches but each side was tensioned dramatically differently, so I had to re tie them anyway.  I got them tensioned evenly, tied them off with the proper clove hitch and then lightly covered the knot with a little CA.  Didn't make a mess, looks nice and there no way its ever coming undone.

Took the 4D out today and the center T has become loose.  Based on some of the earlier posts I know this now needs to be glued.

How about the bridle attachments to the leading edge.  Two of them came loose today.  Looks like they are tied with a half hitch.  Is that how there are coming in?  I am starting to become paranoid double checking each knot to be sure it is still tight before and after flying it.

Got my replacement nock from Prism the other day. I like the concept. A skeletonized nock, that stays attached...(kind of). Tied mine back on...will see if the patented Clove hitch works. I am guessing we are beta testers for this kite. So we will keep track of what parts work....and what parts don't. And alert the proper authorities in Seattle, when necessary.

Check the knots on the Bridle to LE. They'll stay, once tied correctly. I've double checked mine and only had to re-tie one, wasnt quite tied like the rest.

For the nock, i've decided to add a reverse clove after the first two. Or is it, a reverse half-hitch after the first two. There seems to be enough line for it.

I checked them today and made sure everything was snug.  No problems!!  Steve and some other flyers also suggested using wax.  Overall I like this kite.

Once I redid my knots on the nocks per the Steve  Wink, I've had zero loosening. And have had no bridle issues at all...

As with any mass produced kite, the knowlegable flyer will always check knots, ferrules and bridles before the very first flight and occasionally thereafter......It's the nature of the beast, as they say.  The novice soon becomes educated after the first failure or two......(or if he/she reads the owner's manual) Cool

True story.

One of my bridle connections was loose when I first opened the case, but I tied it like the rest and haven't had any trouble in a number of flying sessions.

Being a novice (as if you didn't know by my questions) I learned quite a bit in the role of beta tester.  Being sure to check the original knots on the wing tips did not keep them from getting loose again.  Checking the wrong knot over and over again doesn't make it right.  The two half hitches did solve the problem.  The knots on the leading edge were different than I have seen on my other kites which were a lark head type arrangement.  I am not sure even if Prism did have the manuals ready these questions would be answered.

End of the day I lost no parts, didn't break anything, learned more than I would have if I waited for a year and have a nice kite.  Seems like I came out ahead on the deal.

What is CA?  Is everyone doing this or are most knots holding on their own?  Thanks!

CA glue, used commonly in hobbies and crafts.  After flying my 4D a few times, I noticed the knots starting to come loose and they were tied with the clove hitch.  They aren't coming loose at an alarming rate really, just happened to noticed they were giving a little, so if I have to make a walk of shame or whatever, I just give it a quick once-over...which is what you should normally do anyways.  I'm a bit reluctant to secure the knots with glue or anything in the event I need to replace the nock, I don't want to ruin the string or whatever that ties the sail to the nock.
