0 hrs. walking around the garage and deciding I wasn't in the mood to work on it tonight...  Tomorrow!

Well, I did look at this.  According to other blogs M5 rivnuts need to be installed in the two holes here, which will hold the rudder tensioning springs (See Peter's blog here).  The holes are much too small, so I want to confirm this is correct.  The manuals I have make no mention of this assembly.
