I had that problem on my 11m sonic and tried to untwist it by opening the zip near the main strut and inserting my hand and twisting the bladder in the opposite direction of the twist. After repeated attempts I ended up having to take out the bladder completely and reinsert it from scratch. This also took a few attempts but I now have the hang of how to do it.
lay the kite out and make sure its dry-garden blower if need be-must b dry on the inside of the bladder sleeve!!!!! 1. undo ends 2. tie kitelines to each end 3. pull bladder out-u just leave the lines hanging out the ends waiting 4 u to be ready to put it bak 4. pump up the bladder- not hard of course 5. cover in talcum powder and make sure its well talced up 6. deflate, tie the line ends bak to the bladder, lay the bladder out and pull the bladder back in (two people makes life easy) 7. pump up and the talc will let itself fix its self
or be lazy and do it the way most would bottle of talc poured into the bladder sleeve and shacked about LOL
