servo to control rod options?
I am building a 40 size 3D plane and would like to upgrade the linkage and hardware. The arf comes with 2-56 rod threaded on one end and is intended to be used with a single bend at the servo with a clip. What are some options for upgrading this hardware? I would like to keep it light and simple.

4-40 rods with a ball link attached to an aluminum servo arm and a soldered on threaded coupler (Dubro #336) with a metal clevis (Sullivan #S526) on the other end. Use silver solder on the couplers, all should be availible at your LHS. I've never had one fail yet. This is a cheap way to do it and works well for me but there are many other ways to do it, (H9 titaniam links, carbon fiber links...) just my opinion

What plane do you have. A 6 1/2 pound 40 size airplane is a heavy airplane for 3D if you want the lightest setup then stay with the 2-56 rods with a Z-bend. Fly it and when it flexs(assuming your flying 3D), then upgrade to a better system. Again, just my opinion.

Use a piece of 2-56 all thread going through a fiberglass rod. You can then use either a clevis or a balllink on either end. Simple fast and light

Good information here if you are still undecided on a plan of action. Yes, it's a commercial site, but you don't have to buy anything from them. The assembly materials and techniques are what's important.

Here's a few pics of a Funtana 40 I had. I do all of mine like this. Anything bigger then this is the same set up but with 4/40 stuff. The arms are from Du-bro on the servos. The ball links are Sullivan I think.
