RUDDER INSTALLATION
.....
The rudder hinge assemblies are very similar to those of the
ailerons, so review the section on mounting the ailerons before
proceeding further.
.....
The upper rudder hinge consists of the CS22 plywood mount, which is
bonded to the vertical fin core, and the same hardware and fittings
called out in the Main Wing chapter section on 'Outboard Aileron Pivot
Assembly', so follow those directions.
.....
The lower rudder hinge is detailed in the accompanying sketch. The
QCSMI material is used for a 1.0" length rudder reducer and a 0.5"
length for a rudder spacer. The rudder reducer is pushed into the CS21
rudder torque tube. CS23 is the lower rudder phenolic bearing. CS23 is
bonded to the vertical fin foam core with liberal quantities of flox
generating good squeeze out. Q2CSAI0 is the rudder bell crank, which is
attached to CS21 with a AN3-14A bolt.
.....
Assembly is performed by trial and error fitting of the rudder,
complete with all pivots, to the vertical fin until a satisfactory fit
is obtained. The clearance on either side of the vertical fin slot
should not be less than 0.06". The rudder should be trimmed top and
bottom so that a minimum gap between the fuselage and rudder, and
between the rudder top and vertical fin exists. When everything is
ready, mix up flox and also some 5-MIN and jig the rudder into place and
permit it to cure. Stirring sticks and some scrap lumber can be used to
hold the rudder in position.
