Section 6: Installing the Rudder and Elevator Servos
Parts Needed
Fuselage
Not included
Servos (4) (a minimum of 80 oz/in of torque)
w/mounting hardware
Small cable ties (2)
Using a computer radio
24" Servo Extensions (4) (JRPA102)
Using a non-computer radio
Y-Harnesses (3) (JRPA133)
18" Servo Extensions (4) (JRPA099)
Note: If using a non-computer radio, one of the servos used
for elevator must be a reversed-direction servo. See the
"Radio Setup" section for more details on page 34.
The rudder and elevators require a minimum of 80 in/oz of servo
torque. In the prototype 1/3 Scale CAP 232, we used JR8101 and
JR8411 servos with excellent results. Using servos with less
torque could cause a crash.
Computer Radio
Step 1. If using a 7-channel or greater computer radio with
mixing (highly recommended), install four 24" servo extensions,
one on each servo. Tie a knot at each connector and tape to
prevent inadvertent disconnection. Also install the servo
hardware (grommets and eyelets) at this time.

Small straight screwdriver
Non-Computer Radio
Step 1a. If using a non-computer radio, install four 18" servo
extensions, one on each servo. Tape and tie a knot at each
connector to prevent inadvertent disconnection. Install one side
only of the two Y-harnesses to two of the servos, also tying knots
to prevent disconnection. The other two servos will be hooked up
to the Y-harness when installed in the airplane. One elevator
servo will need to be a reversed-direction servo.
