Cat,
I'd still say that it's not a good idea. The problem is still there. The screw can loosen up on the ez connector and the control rod now can slip, and you lose control of the plane.

There is another solution that I recommend. If you get solder clevises you can solder a clevis on at the control rod, and connect that to the servo arm. [link]http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXK082&P=7[/link]


Hope this helps
