What you describe doesn't sound good...
Have you flown any other kites in this same field?
Flying in fields is generally a bad idea, especially if there are sizable trees/houses upwind or downwind of you. There can be lots of turbulence, which could quite easily cause what you describe.
If you have a bank of 20m high trees, you wanna be 200m at least away from them - even at this distance the wind will still be pretty sketchy.
I figured it was turbulence after the first time out, though nothing major upwind the fields are far from flat round where I live. I took it to a different location, where I have flown a naish helix on the rrd bar which flew really nice and it exhibited the same problems.
Try it on the beach with onshore/cross-on conditions before you make any conclusions.
If it is really just susceptable to turbulence it would be a shame as im a long way from the coast, probably only get to go a 3 or 4 times a year so it needs to be good enough to snow kite during the winter.
-Check the bridal inserts are both factory set up. Someone may have put new inserts in and not doen it right
- Pump the obsession really hard. So on the last pump you really but a bit of muscle into it. sounds like you definitely under-inflated the kite f the tips are shakey.
-Open all the one pump clips up and see if that improves
-You could have a small leak. Pump kite up and leave for a few hours and check the pressure.
As far as I can tell the bridal is completely stock, though I havnt measured it or anything, just looks identical to pictures I have seen.
I pumped it up hard, always do, no leaks or at least nothing that makes a noticable difference as its still rock hard after 5 hours. I didn't close the clips as I figured they were only used on the water.
Is it possible that the leader lines on the both wingtips were hung up on the very tip of the leading edge?
No, I self launched it so got a good look at everything.
I honestly think 12 knots is not sufficient wind for a 9 meter. Will it fly? Yes. Will it fly well? No. When flying in 12 knots was the kite out of control, or just sporadic and noisy? When the gusts came through was the kite seemingly more controllable?
Just sporadic, the noise wasnt flapping at trailing edge as I have seen some kites do, it was just occasionally snapping the bar up then going slack which caused a loud cracking sound when it happened. If I flew the kite hard it was incredibly responsive, and really powerful, enough to jump and hang for a few seconds, definately enough to be bombing it on a surfboard. The gusts didnt make too noticable of a difference, the wind could be blowing hard for a moment 15-18kts, and it would still backstall if I tried to park it, the only thing different was when it did decide to change direction it came back out of the window that much faster which wasnt too comfortable.
If the kite is acting all crazy, it is likely the bridal. Usually when I see kites behave in this manner, it is somebody borrowing equipment from a buddy who jerry-rigged the crap out some broken bridals. Take some pics if you still have problems. PS< is the bar RRD? Have you tested the Quick Release?
The bar is the rrd global bar that came with the kite, quick release works fine as does the bar and lines with other kites.
I will get some photos of the bridal, thanks for the imput guys.
