The rudder requires a minimum of 100 ounce inch
of servo torque. In the prototype CAP 232Gwe used
JRPS8411 servos with excellent results. Using servos with
less torque could result in blow back.
The rudder servo installation is very similar to that of
the elevator and aileron servos. You can either follow
the steps as described, or just use the last photo to
illustrate the direction of the servo and layout of the
completed linkage.
 Step 1
Install an 24" (610mm) servo extension onto the rudder
servo. Tie the servo leads together, using a commercially
available connector, or use unwaxed dental floss to
secure the extensions to prevent them from coming
loose during flight.
 Step 2
Remove the covering from the rudder servo opening on
the left side of the fuselage using a hobby knife. Install
the servo in the fuselage tail section with the output shaft
to the rear of the fuselage. Drill 1/16" pilot holes before
installing the screws. Using the screws included with the
servos, fasten the servo in place.
 Step 3
Mix a small amount of 30-minute epoxy and lightly coat
the inside of the hole in the rudder and the 8-32 x 2

control horn screw. Thread the screw into the hole from
the right side of the rudder. Wipe away any excess epoxy
on the rudder and screw with rubbing alcohol and a paper
towel. Screw the 8-32 flange nut in place as shown. Allow
the epoxy to fully cure.
