1. Attach the motor
(not included)
to the Motor Plate (96) using
two 3mm x 8mm Button Head Screws (141) and two #4 Washers
(58). Do not tighten the Screws yet.
*NOTE: There are usually four mounting holes on a motor can. To
install the motor, you must use two holes which are not vertical with
each other as shown in Figure 50B. Choose the set of holes that will
allow easiest access to the solder tabs on the motor.
2. Attach the pinion gear
(not included)
to the motor shaft by
aligning the set screw in the pinion with the flat side on the motor
shaft and tightening. Adjust gear mesh so that there is a little "back-
lash" between the Gears, and tighten the Motor Screws one at a time,
checking the mesh between the tightening of each Screw.
*NOTE: The gears need some backlash in order to function prop-
erly. Too much though will cause failure, so be sure to check the
Gear mesh at different points in the rotation of the Spur Gear.
*NOTE: Some of the Gear Covers may come pre trimmed from
the factory, with mounting holes already in place.
3. Locate the Gear Cover (142) and cut the back side of it along
the trim line as shown in Figure 50A. If not already present, drill
three 1/8" mounting holes in the gear cover at the three locations
marked with dimples.
4. Place the trimmed Gear Cover over the Motor Plate and se-
cure it with three 4-40 x 1/8" Button Head Screws (143) through the
three tapped holes in the Motor Plate.
5. Install the Gear Cover Plug (144) into the large hole in the
Gear Cover.

1. Using Table 52B (on the following page), determine which
Servo Arm (145) (found on the Steering tree, previously used in Bag
A) is required for your Servo. If your particular Servo is not listed,
try using the Arm recommended for another Servo made by the same
manufacturer.
Some Servos may require the use of a Ball Stud Washer (9) placed
behind the Ball Stud (11) for proper Servo Link alignment, as shown
in Figure 51A.
2. Insert a 4-40 Mini-Locknut (7) into the hex area on the back
side of the Servo Arm. Thread a 3/16" Ball Stud (11) through the hole
in the Servo Arm, into the Locknut, and tighten.
3. Plug the Servo into the radio system’s receiver
(not included)
.
Make sure that there is power to the Receiver, and turn the transmit-
ter on followed by the Receiver. Be sure that the trim settings for the
steering on your transmitter are set to the center. With the radio sys-
tem still turned on, attach the Servo Arm to the output shaft so that
the Arm is one spline off center in the direction shown in Figure 51B.
Secure the Servo Arm using the screw supplied with the Servo.
