I have digged out htis thread for the following.
I own a Liquid Force Session 6qm from 2009 for very strong winds.
Over the last sessions, I came to notice that the tips tend to snap and fold insight ("squeeze") as soon as I pull the bar hard.
It feels like the main strut (front strut) at the very end of the tip is not strong enough to hold the pulling forces by the backlines through the bar.
Then it starts to stutter really bad, so I have to release the bar.
I am inflating the kite properly and it also does not loose any air.
Did you ever deal with that proplem?
Is there any way to enforce the wing tip, so it cannot snap?
I am looking forward to receiving any support.
Best regards from Germany
