Parts Needed
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.
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.
