MODIFY THE SERVO HORN
There are many servo horns available. The round one is the
best one.
You must modify the horn if you are not using the round one.
Trim them so they don't go beyond the #6712 throttle wiper
arm outer edge. Also trim so it will clear the resistor.

INSTALL THE MOTOR
Attach three capacitors to your motor according to the instructions that
came with your motor, if they are not on already. For the
Sport kit,
solder the colored plug wire to a positive tab on the motor and the
black wire to a negative tab. For the
Basic, Team & Factory Team
kits,
you must buy your own motor, then follow this step.
Install the #6681 gear with the #6951 set screw going to the flat side
of the shaft. For the
Basic, Team & Factory Team kits
,
you must buy
your own pinion gear. If you use an electonic speed control, see its
directions for installing motor capacitors.
Use two #6515 screws and two #6936 washers
to mount the motor as shown so the gears mesh.
SET THE GEAR MESH
You should be able to rock the spur gear back and forth in the teeth of
the pinion gear without making the pinion gear move. If the plastic
gear is tight, then loosen the #6515 screws and move the motor
away, then try again. A gear mesh that is too tight or too
loose will reduce power and damage the gear teeth.
