The CAP 232G has two options for mounting the rudder
servo. For lighter engines, a pull-pull system is used. For
heavier engines a tail-mounted servo is used.
The rudder requires a minimum of 100 ounce inch of
servo torque. In the prototype CAP 232G we used a
JRPS8411 servo with excellent results. Using servos with
less torque could result in blow back.
 Step 1
Thread the 8-32 x 4" control horn screw into the hole in
the rudder and epoxy in place. Thread the 8-32 flange nuts
onto the screw from both sides of the rudder. Position the
screw so it is centered in the rudder. Use threadlock on
the nuts to prevent them from loosening during flight.
 Step 2
Cut the cable into two equal pieces. Prepare one end
of the pull-pull cable using the cable, threaded cable
end and crimp. The cable passes through the crimp,
through the threaded end, then back through the crimp.
Pull the excess cable tight and use a crimping tool to
complete the job.
  Step 3
Screw the molded swivel link onto the 8-32 screw
until the distance from the rudder surface to the top of
the link is 11/16" (17mm). Thread the cable end halfway
into the ball link. Pass the cable into the fuselage through
the opening.
