if you pull out the whole bladder just connect it to the tubes from the struts and close the valves. pump it up and see if there are any holes in.
If you want to put it back again, just reassemble the main valves (inflate and deflate) in the leading edge and fold the bladder (length ca. 40 cm like a accordion) in the right direction to both sides. And slowly but it back to the leading edge with the previous fixed lines from your bar before you pull the bladder out of the leading edge.
I can do that in now time with this tips. Need 5 min. I am trained now. I did it 20 times or even more with my 2010 13m Rise. I put on my baldder now more than 20 patches and I am a little bit pissed off, because there are scratches of several centimeters, without doing anything. No crashes etc. I flew it twice. The second session I go out I have to abort the session after 20 min because of a pressure problem at the leading edge.
I contacted my dealer and he said he couldn´t reach our europe rep. He ordered bladders and it´s seems to be a known issue. But I didn´t got my new bladder (I ordered it 20 days, ago!!!!!)
