Ozone speed system adjustment

[foilholio]

Wow that mixer is a little bit confusing. Seems far too much ignoring Z. Z is the bridle that shrinks and changes how the kite flys the most. I like the half length pulley line for B, flysurfer could really use that. You might want to add an extension to Z if the bar pressure is higher than you remember and its not as good upwind and less stable. If specific parts of the kite are playing up restretch the bridles.

True for the Flysurfer kites, but not quite as important on the Ozone kites.

The Pulley lines will shrink quite quickly (within the first 20 hours) because of them running over the pulleys and the coating wearing off. They will shrink a lot more than the very think break line. It is unlikely that anyone on an R1 will be having a problem with their break within the first 20-40 hours. Later on you can measure your break lines and compare them to the original lengths on the diagram you can get form the Ozone Website. If its too short, then you can just move the knot up towards the kite.

Yes the brakes are quite thin and should minimize shrink. Saw that knot, but wouldn't it act as a stopper, especially on bigger kites, limiting depower? Or does ozone use different size mixers? The pulley line is quite thick, seems a bit overkill.

[gmb13]

The knot is no where near the travel of the pulley, so it's not an issue.

How often did the guy used this kite?

Hi,

put pigtails with a bit extra line between red thinner lines and the others, so that you can move the knot a bit. You will need to shorten the others involved if you want to keep overall/original lengths.

We did this few times.

Thanks for all the replies. It's a sunny no wind day today too, so I'll see if I can investigate further.

I've done what is shown on the Ozone website, there is no reference to the Z lines and the photo shows only the 3, hence why my images show ABC only. So if there's a way that includes the Z lines, then I'm happy to look at that too.

Thanks a lot for this topic !!!!

how does the kite fly if A,B, C are ok (0) and Z is too short or Z is too long?

[foilholio]

Looser(longer) Z allows B and C to be tighter creating a negative camber or reflex. It will be more stable with lighter bar, will have less lift(grunt) may have better upwind and float or L/D (more LIft to less Drag). Tighter(shorter) Z allows B and C to be looser creating positive camber or a hollow profile. It will be less stable with heavier bar, have more lift most likely will have worse upwind but better downwind. Optimum L/D is somewhere around flat.

Watch this video. Just remember shortening Z 4 is the same as lengthening C 2 and B 1. And Lengthening Z 4 is the same as shortening C 2 and B 1. (Except of course changing the B length "can" change the amount of depower and stability depowered.)

have look at the nasa link on the second post here viewtopic.php?f=197&t=2392205&p=925922& ... sa#p925922

If you play with the knot on the pulley line in the ozone mixer to adjust Z, make sure it doesn't interfere with the B limit for depower as that is something else and will change the kite in ways other than just playing with Z, unless of course you want to do that as well.

If you want me to explain further why one thing does another ,etc, just ask.

@ baxterbradford, Thanks for starting this thread, as I was just about the ask the same question regarding the speed system on one of my Chrono’s.
Having performed the “Speed System Zero Position check", I have a similar problem and have been considering what action to take over the last couple of days.

Option 1: Replace the speed system “like for like” but end up in the same situation in the future.
Option 2: Replace the speed system with the Ozone “Pro Tune Speed System “
Option 3: Convert the current speed system to a tunable speed system.

These kites need to be periodically checked and tuned as needed, so being able to make the necessary adjustments to the speed system in order to maintain performance looks to be a must.
With respect to the Ozone “Pro Tune Speed System “ there’s a video that shows how to check, tune and replace the entire system and a PDF showing the dimensions as well.
I think I will be going for option 3, will upload a picture once completed.

@ gmb13 - Have just applied your fix and it works a treat Thanks very much.
Will use that fix in the interim.
