RADIO INSTALLATION
Fig 79.
Step 1. Remove the servo horns from both of the servos
supplied with your radio system.
~
It is highly recommended that you use the
Kimbrough type servo saver for your steering servo horn. Be
sure to use either the large black or white one. Do not use the
small grey colored servo saver.
Step 2. If you will be using a standard servo horn (sup-
plied with your radio system), refer to figure 79 and trim one of
the arms accordingly, removing the shaded areas of the arm.
This will be used for the steering servo. The wheel type arms
should not be used for the steering servo.

Step 3. Thread a 3/16" ball stud (21) through the top
hole in the servo horn, or servo saver. The ball stud (21) should
be attached to the side of the horn opposite the side that at-
taches to the output shaft of the servo. The hole in the horn
may need to be enlarged slightly in order for the ball stud (21)
to thread through it.
Step 4. Secure the ball stud (21) with a 4-40 nut (167).
Fig 81.
Step 4. Determine which throttle servo horn (168) you
will use by referring to table 81.
Step 5. Insert the throttle pivot (169) in the outside hole
in the servo horn (168). The pivot (169) should be attached to
the longer arm of the servo horn (168), and inserted from the
side of the horn opposite the side that attaches to the output
shaft of the servo.
Step 6. Secure the throttle pivot (169) with a 3/32"
'E'-clip (170). Be sure that the throttle pivot (169) rotates freely
in the servo horn (168).
