I just bought a pair of YS-250 strobes so ordered a new set of arms too. After looking around I went with the UCLS arms with a 5" and 8" section.
So when everything got here and set it up. One thing I noticed was the joints seem "loose". I have tightened the joints to the point right before having to put a lot of force on them. it helps but it will still not support the strobe. I can start craning down on the joint but didn't want to damage the screw or O-ring. How tight should you have to make these? I know the YS-250 is a heavy strobe, is this the wrong arms for these?
