RJM,
Here is my list in order of what I prefer for connecting pushrods to servos.

1. Ball links [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXD897&P=0]Dubro Ball link, threaded[/link]
2. Solder Clevis [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXD895&P=0]Dubro Solder clevis, 4-40[/link]
3. Z-bend [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXXC81&P=ML]Great Planes z-bend pliers[/link]4. L-bend [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXAZC3&P=0]Dubro E/Z Links[/link]
5. EZ connectors [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXD925&P=0]Dubro EZ connectors[/link]

The first diagram is a how to for making Z-bends. The second diagram shows what L-bends look like.

I know that there are those that disagree with me, but I don't like using EZ connectors on critical flight surfaces like the aileron and elevator because I have seen them come loose in flight and if that happens you will loose the plane. I use them on non-critical applications like the throttle and nose gear steering.

Hope this helps

Ken
