had a friend buy a good as new sonic built august 05 from a W.A shop. finaly got his second session in and did a 20m run on his board when the leading edge seam split. Compared it to the halo and you can see why the stitching came apart. Besides that it either had no steering or would oversheet in light winds . does any one know a good kite repairer for this dud?

Contact the place of purchase. I realise that it is over the 90day period but there is reference to this happening in most occasions. What is GK doing bout this, anyone? Are they warranting such problems?

prob was a faulty or didnt check the seam as nearly all bow kites split at the seam cross bows ect.... it isnt a c kite takes some time to get used to flying i personally had 8 and 11 and friend 14. all kites can over sheet in light wind bows and c's... u have to tune the kite which really isnt that hard adn i found the perfect setting and didnt have to change it after that only for really strong wind where i depowered it. u need to sheet the bar in to turn the kite to get back line tension. and go to " hold the line kites" in wembly he is great for repairs! as you've said he has used it 2 times... it takes a little while to get used to but once u have got used to it sick kite! was my fav out of the 06 bows and the waroo! u can do it all on the kite!

I got a 14mt Sonic. I had read about all these seam splitting stories and was glad I had a good one. However just recently found my LE was tearing at almost all join points. It seams that the bulk of fabric and the sewing machine tension are all wrong. This is my opinion is a production QC fault.

I love this kite and the way it flies fantastic with the tuning mod mentioned in some other posts here. You really need to tune it properly to get the best benifits.

I spent 2 hrs handsewing the points with waxed whipping twine. I felt that even if I sent it to a repairer I would still have issues later on. It is a bit extreme what I have done but having been disappointed before about bad workmanship, I decided to do it myself.

Unfortunately the Sonic is really cheaply made. I think we can all agree that is a fact. I still like the kite and will keep it till it explodes cos the 2nd hand market for them will be a joke. You get what you pay for I guess.

Anyone whom has a Sonic and reads this please check your leading edge at the joins and try and get it fixed before it totally rips thru.

All the best and hope your LE doesnt rip!!!

Interesting thread. The quality of the sonic seems to be pretty variable. I've had mine since December and have used it extensively since. Its become my standard kite and I use it in preference to my other C-kites. This kite was getting out of the bag a couple of times a week through summer (but a little less now )

I haven't seen any sign of stitching problems on the LE or anywhere else. The stitching generally looks fine with balanced thread tensions. I'm not 100% convinced on the rear line attachment points - the pigtails look a little bit weak. I think I'll replace them with 2mm spectra. Otherwise the construction looks solid and the reinforcing generally looks tougher (more dacron, stickback and patches) than I've seen on other bows.

I have a 11m sonic. It has exploded on the LE. It has been fixed and I am reasonably it will not happen again. I love this kite as it will do me quite comfortably in 15 to 30 knots. It is the only kite I use pretty much now, but I am still a little worried about the durability of it.

Stonker Kites replaced my Kite (the same one that started this discussion , leading edge Split) with a new one. Seems to me the backup and customer service for GK is excellent. The new kite has a little more reinforcement than the old and is the latest release but the leading edge stitching looks the same, maybe less pressure in the LE is required ? Any suggestions ?

Thanks again to Stonker Kites

In my opinion the Gk flies best with a good amount of pressure, especially in strong winds. I was flying mine in 30+ knots winds sheeted in quite a bit when it looked like it was going to invert. It dropped from the sky a little bit and then filled again launching me up a bit. When I came in the pressure seemed alright but seemed fly better the harder the leading edge was.

6.5 psi works well for me, remember the 11m is not designed for 30 knots(GK states range to 25 knots) this will lead to stiching problems through stress and deforming under load, get a 8m if you want to kite 30 knots such a sweet kite.
The sonics turns better when at 6.5 psi - over that they can feel wooden but stable. Have not had any inversion problems but I put the 8 up in over 20 knots it is a really grunty little kite.

I’ve had my sonic 11m for about 5 months, and have no seam problems yet, even though it has been tumbled in the surf many times. I have found the wind range quite large and have been out in 30 knots, gusting to 35. It starts to behave badly in those conditions however it is still quite useable. And yes the leading edge must be pumped up hard otherwise it is a pig. I don’t have a pressure gauge so I squeeze about 6 inches in from the end on the leading edge. If my fingers can touch, not enough pressure.

I have also found that the kite flies better when the rear lines are connected to the forward attachment point on the trailing edge. It steers a lot quicker and has a better feel at the bar. It depowers quicker (less bar travel needed) however it feels as though there is slightly less bottom end.

On the negative side I have had problems since new with one bladder that had a manufacturing fault and have not been able to purchase a new one. It appears that you can’t get parts for them and it’s not because of the retailers....... Also I had the webbing break between the chicken loop and cleat. When this happened the safety disengaged as it got pulled through the chicken loop/cleat cover. Lucky it landed in the surf and didn’t hit anyone on the beach.

Would I buy the same kite again??............not sure at the moment……

I'm only new to kite boarding and have recently bought a sonic 11. Your comments scare me a little...however, while talking sonics can anyone comment on how they find the front line adjustment and cleat and has anyone fitted the retro front line kit (reverse cleat and double line)... seems a bit agricultural...not sure about the durability of spectra turning thru a steel ring ...thought a small pulley would have been better.

I think on close inspection the failure rate of Sonics is very normal
and seems to be being blown out. I anm not condoning any failures and still believe the companies need to improve their specs.

As far as spectra line thru ring goes.

My experience and those of most all Airblast bred Kiters is that spectra when run thru any pulley system, and the ring is a pulley system, breaks. It first breaks the core which is undetectable due to the sheath. There are alternatives to that type of spectra that survive longer. Also of note is that during the airblast reverse launch era, condition of pulleys did not seem to be a cause. Of course back then if the line did break, you could rap the steering line around the bar a few times and get enough steering to get yo back.

As far as sonics go, I know Alex at Stonker is more than happy to help to the best of his ability.

Bribie Rob,

I have been trying different setups for my trim line over the past few weeks and have ended up having the cleat at the top of the trim line instead of at the base. This seems to work better for me, however it affects the usability of the stopper ball. I tend not to use the stopper ball at all and ended up taking it off. I have just changed it again tonight so I'll test it again in the next few days if we end up getting any wind.

If you live on Bribie Is (as your name suggests), your more than welcome to have a look or I'd be happy to send some pics if works alright.

No system is perfect yet(07 we hope), just get used to it and worry about getting time on the water which with the wind range you will. Sonic bar grows on you after a while - stops you being lazy and resting on the stop. The advantages far out weigh the negatives; if you play around you might cause yourself more grief especially if you have little experience.
I went from slingys to the sonic - serious culture shock(self launch/land, no rest on the stop, etc) - but would never return love the depower/turning speed/light bar pressure/upwind/wind range/jumps/relaunch, yes they could be built better but they would cost more then.
Inspect your gear before you go out and enjoy.

I disagree about resting on the stop being lazy. I tried the Sonic with the stopper and it is hard working having to edge when a gust happens. It is so easy to just ride along holding the bar with just the friction of two finger tips and let the weight of your arm control the trim. The Sonic is such an easy kite to ride.

St Kite,

I was actually after some strut bladders........however I'm interested in how much you are selling it for? I like to have spares.

I use mine without stopper ball. prefer the the safety aspect of this and haven't had too much trouble getting it back if I let go by grabbing the chicken loop rope

yeah - its a no brainer to pull in on the trim line when the bar has been fully released. What I find is that I rarely get to this point though. I can usually access so much depower by just easing the bar that most "situations" can be resolved while still holding onto the bar.
