I'm not confident in using CA hinges. I might be all wet but I haven't ever had a pinned hinge fail. One thing I have read in the thread's about CA hinges, their not for planes over 40 size, generally. Maybe the 120 control surface was just too much stress on them.Like I said, this is pure conjecture as I haven't used them. (too chicken) BWAK BWWWWAAAAAK BWAK
