step 1
ADD MOUNTS TO THE SERVO
Find the appropriate #9180 servo horn for your servo from the chart at
right. Install the #3858 ball end into the servo horn. Add the #6272 dust
cover. Remove the servo horn from your servo and replace it with the
#9180 horn that you selected, then fasten with the stock mounting
screw that came with your servo in the position shown below.
DO NOT
POINT IT STRAIGHT UP!
See drawing for correct dimension.
Find the appropriate #7336 offset spacer for your servo from the chart
at right. Attach the spacer, if any, in between the #7336 mount and the
servo with the #7337 washers and #6917 (6860*) screws.

On Futaba servo S3003 and on all KO servos you will need to trim a
little off the sides of the servo ears. We have not tested any servos that
were released after mid-1999.

MOUNT THE SERVO
Mount the servo to the chassis with two #7673
(6934*) screws.
Twist #6274 ball cups onto #1356 blue turnbuckle or
#3867 steel turnbuckle until you get the dimension
shown.
Use needle-nose pliers to attach the link
to the ball ends.

INSTALL YOUR MOTOR
Attach the #3930 (3932*) motor
cam to the optional motor with two
#3934 button head motor screws.
Install the optional pinion gear of your
choice. (Refer to the gearing chart on
page 19.)
Install the two #4449 locknuts to the
underside of the chassis. These fit tight,
so be sure to put them in straight and
all the way in.
Slide the motor and cam down into the
groove of the chassis.

Screw down the #6928 inner
screw first until the #3931
(3932*) motor clamp just
touches the chassis bulkhead.
Set your gear mesh.
Slide the #3929 spring onto the
#3929 screw and thread in only
until there is no free play
between
the screw and spring. Now tighten
the screw 2 to 3 turns.
No more.
It is
normal to have an approximately
.040"-.050" (1 to 1.2mm) gap remain
between the clamp and the
bulkhead, as shown.
