I've had many customers with Sonic's now and it's critical that you have the correct front / rear line lengths. Sounds like you have a brand new kite - I assume a new bar aswell ? After about 10 flying hours your rear lines will have shrunk and you'll need to lengthen by a knot or so under the bar floats. This is normal.

If your mixer is not ABCZ all equal, then reset to that. We had a couple delivered slightly out of whack.

Sonic should fly well with neutral mixer, but as others have mentioned you can shorten B / C 1cm at a time to reduce camber and increase stability.

Occasional Lower Wingtip folding when riding deep downwind ( ie foiling) is common, and required careful technique to avoid. Rear line tension here helps.
Already changed to the second knot on the steering lines. Also checked the bar and the lines are equal with trimmed out and bar pulled in so it's not the bar. My Sonic came from FS with B+C both 1cm shorter than A,Z and I've heard of other sonic owners with messed up mixers so I highly doubt equaling ABCZ will make these Sonics fly well. Right now it looks like my sonic is flying better at A=Z, B -2cm, C -1cm. If I have a couple hours with nothing to do I'll try to measure all bridle lines but this kite has been like this since day 1.

I really enjoy reading Threads like this ; amusing how different people look
at the same thing in Two different sports !!

On a PG ; we actually have a string we can pull, to collapse the wing tips
cell by cell, (up to 1/3 the aria of our glider) to kill the glide ratio and increase the rate
of decent, for setting up our landings . We can actually land with the tips
collapsed ; but the flair-window is really small , and if Ya don't get it right, you
might hit kinda Hard.

the sonics are shipping with A and Z a little longer than B and C. both my sonics came that way. they all fly just fine with the occasional tip tuck. u cannot get away from some tick tucking on these kites its the nature of the thin profile. if u want a kite that has a lot less of tucking then look in to the speed series. how often do u get tip tuckin is it every session? is it during launch -(which is normal) or during flying? I wont go messing with bridles on till ure sure u have a problem .

I have seen sonics that don't tip tuck at all in flight and I have seen just about every foil tip tuck, depends on the settings.


Bigears, Armin from flysurfer seemed a bit obsessed with it for a while.
