I have a sonic 3 13m ex FLYSURFER demo kite purchased last summer haven’t been able to use it much as the left side folds like that. Very annoying and waste of Kinsey. No one seems to be able to advise on a fix. Armin stated to try tightening the lines along the section that folds on the lcl’s but it wasn’t very specific as to which points you should do it in and how many. But too advanced for me. Wish someone like benni who designed the thing and understands it all would would advise on the issue properly.
Try shortening c on that side by like 1-2cm. The b will then shorten as well.
You could do the C shortening as a quick fix, but i would make a symmetry check first, bc the right side seems to fly stable.
The downside of just shortening C is, the full left profile gets less performance and as Armin said, it is only necessary to change" the profile along the section that folds".
Watch the left side while flying eg figure 8tes , first more horizontal then more vertical. You will see the left side collapsing when it is on the outside of the sharp turn. Try to identify where the collapse begins, typically you have to decide if you want to change the outer 4 sections or more around 6.
For the change of the profile ( after symmetry check, including the outer Z and the Long mixer Test) you can change the profile to more stability in two ways.
1: Make the Lcl of the a lines longer (typically the outer 4 or 5/6)
How to : Have a look into the repair kit there you will find the pink Lcl. These are 2cm long. Undo the knot and make a new one to get a loop 7-12mm long. I like to have 7mm on the inner section and 12mm at the tips.
Unsleve the a lines from the original pink Lcls, sleve the new shortened Lcl between. Refix the a lines on the new knot.
Or make longer Lcl for a cleaner setup ( Liros DSL70) https://www.liros.com/catalog/en/dsl-70 ... ariant=157
2. method ( as Armin suggested)
Shorten the b lines at the corresponding sections with these trim knots https://skywalk365-my.sharepoint.com/:x ... Z48q6bh2kg
https://flysurfer.com/de/2021/09/our-vm ... acecourse/
The problem with the trim knots is the hassle of undoing them if they get tight, it is possible the hurt the thin lines.
My suggestion to all Soul and Sonic3 users:
Keep care of the thin bridles, don`t kink, crinkle, bend them in a tight radius. This will break open the prestretch coating and the dyneema lines will get shorter ( more and faster in the unloaded sections) Just throw them loosley into the folded foil und don`t make half hitch knots with the bridle or the mixer onto the bar stick, just use the elastics on your bar ends.
Be gentle to the thin lines when unknotting loops of the bridle.
Read my comments in this thread of leveling , adjusting the Z bridle to the lenght of A. It gives you the opportunity to check 80% of the profile sections via the " full long mixer test"
I like the possibility of an adjustable mixer, like the FS mixer but i agree with Ice101 there is not much information from FS how to fine tune your kite and what really makes the airflow when the profile is changed. Here FS is in a dilemma. On one side they want their dealer system to help out their clients ( which some have the knowledge and some only seem to want to sell some sparepart lines
) On the other side they don`t want to scare off (new) clients with these common , often easy problems of tuning the bridles. FS wants the advantage of performance of the unsheathed, thin dyneema lines vs the thicker sheathed (Ozone,PLKB) but is unwilling to understand that these extremly long lasting canopies need some fine tuning beyond the LMT after some years of use or earlier if the bridle was abused.
Please Flysurfer, think about it. Your best " How to long Mixer Test" video is not on the FS Youtube canal, it`s on "Our Kite Life" !
The FS "How to" videos are misleading and with bad didactics. ( Somebody holding lines on same level, while other person keeps tension with 5 Kg, hilarious,pathetic!)
Why not making some longer LCLs and packing them in the repair kit,( I suggested this years ago on the famous Oase thread " Endlichkeiten Mixer Test") instead of PMA`s which nobody uses and cost performance when unnecessarily used.
