I am trying to figure out what to use for my retract servo switch push rod. I have a Hitec HS-81 (mini servo) going to a SpringAir retract switch (both have small holes). What do I use for pushrod? I tried paper clips but one was too big for the holes and the other too small. Please let me know what you are doing. Thanks.

I used a standard push rod and mini clevis, the kind used on electric planes, and put a z bend on the servo end. The Spring Air valve requires very little effort to move it. You can also drill the hole in the valve arm to accept a standard clevis.
