REFLECTOR: Rudder Travels

[Al Gietzen]

Craig;

 

I had a similar situation.  You may get a slight amount of cable stretch,
but the pedal travel should not change with pad wear.  When you check your
rudder travel, have some pressing pretty firmly on the pedal.  Rig them for
something close to 4" travel.  If you can, thread cylinder rod further into
the slide block at the pedal.  I ended up moving the connecting point at the
rudder horn for a shorter arm at that end to get the travel.

 

FWIW,

 

Al

John and I are having a small disagreement on rudder deflections.  The book
calls for 2.5" of travel prior to brake engagement, which we have.  The part
we are disagreeing on is the travel after that point.  In the rudder rigging
chapter it calls for 4 inches of travel when setting your pedals total
travel.  In the finishing chapter it says 3.5 to 4.  We have 3.25 (L) and
3.325 (R) because the master cylinders can't compress the brakes anymore.
As the brakes wear down the travel will increase, right?.  If we take the
master cylinders off we get 4 inches before the pedals bottom out against
the canard bulkhead.  Just wanted to bounce that off the "collective wisdom"
of the reflector and see what the consensus is.
