Pull-pull rudder servo installations seem to vary widely -- from the disc/braced installations to keep rudder geometry constant at all angles (and avoid slack cables), through to simply looping pull-pull wiires through a standard, tough horn.

First question is who supplies the braces and disc based horns if you go that way? I haven't been able to find these at any of the local Oz suppliers, or the better known international ones.

Any other hints from the experts on robust and durable rudder installations and the benefits of complex versus simple installations (I recognise there will be many opinions -- but I haven't found a thread that contains them!)
