I'm building a 1/2a and using micro servos,
the control arms are very small on the servos.
I've been searching for adjustable micro push rods
and connectors. Who's a good vendor for micro
hardware?

Plain ol' music wire from the local hobby shop. Nothing in the way of the usual hardware is sized to fit the micro servos. What I do is use whatever size of wire is needed to fit the holes and put an L in the end of the wire. I then use a grinding wheel in the Dremel to cut a notch in the wire just near the end of the offset leg of the L. A 1/16 length of 1/16 aluminium tubing is then placed over the ground notch and crimped so it swages into the notch. It won't come loose now for any normal load at all. But if you grab it with a set of small pliers and twist it you can pull it off quite easily. For adjustments I bend a "_/\_" or a Z into the wire and shrink or stretch this offset with pliers for adjustments. At the tail it's just a straight run to the horn and another L plus tubing crimp to secure it.

Actually, dubro i beleive makes a nice set of micro control peices. they have a nice system of connectos that is very efficent and as long as your not going 100mph woudl be more then adequte. my LHS carries these and i am using them for my planes currently and love them. they are easy to use and easy to adjust.

here i have links to almost everything you would need to set up almost any micro control system you could want, under the assumption your buying premade parts.

I use these on every single plane I own:

Some people have expressed concerns that the rods would slip, but they don't. Especially not at the forces these small servos are making. Perhaps an issue for 1/4 scale

If you put the screw piece on the control horn, you can even adjust it without having a remove a wing (depends on how scale you want your plane to look).

Yes, these are what I'm looking for. I called myself
doing a search on Tower Hobbies and must have
over looked them and the other link is a good
deal also. This micro stuff is all new to me, I've
been flying .40-.60 size planes and bigger the better.
I'm starting to like 1/2a, I can build 3 planes for
what a .40 size costs. They might not impress any
one but who cares when your having fun.

Thanks

Control horns made from 1/16" plywood [that is imbedded into slits that are cut into your control surfaces] work great, and look neater than the hardware store type. It helps to have a numbered drill index so you can drill slop free holes to suit your wire. .030 - .055" wire works pretty well if it is supported. I have made drill bits from the wire itself to drill custom holes in the servo arms and control horns.

I have made drill bits from the wire itself to drill custom holes in the servo arms and control horns. Don't forget pull/pull control with 1/8" dowel control horns and Spider Line. I don't bother with turn buckles, just tie a movers' knot to cinch it up. When slack creeps in, just twist the line with a piece of fine wire and glue the wire to the main run so it can't come un done. Cheapness and simplicity means that more time and money can get spent elsewhere.
