I use [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXD930&P=7]those[/link] for throttle or nose gear steering but not on a control surface. At one club I belonged to it would not pass the safety inspection.

How about trying another "Z" bend and then snipping the wire and making an "L" bend and then splicing in a length of dowel to get it back to length? I've flown lots of models with 4" of wire on either end of a dowel for a control rod. Set the wire back 1" with the "L" end set in a small hole and heat-shring or wrap with string/thread and glue to anchor the wire in the dowel.
