I have a SIG Four Star 60 that I would like to do some mods to. I will first increase the rudder by an inch. This will be easy and from what I've read give me more rudder authority.
The second one is a little harder. I would like to set up a pull pull rudder system on it. Here's what I've gleaned off the net concerning pull-pull rudders {correct me if I'm wrong}.

1. Make sure the length of the wires are the same.
2. Make sure the servo horn and control horn are the same distance.
3. 1 and 2 make the geometry the same which is good.
4. You can cross the wires but this creates other problems.

Included is a pic of one another member did. The back one is the rudder setup. This looks like a good option and I realize I will need to glue some plastic rods into the fuse for the wires to exit.

In summary, I would like to install a simple pull-pull system to get maximum throw and help stabilize the rudder better than the standard set up. Any photos, methods, suggestions would be appreciated.
