Install the battery locater with 2 2-56 flat head
screws.
You can secure your batteries with the supplied
battery o-ring or strapping tape. Both methods
work well.
Congratulations, your done!
Go to the starting setup sheet, adjust your car to
the base setup and hit the track!

Step 27
The Servo mounts are attached to the lower chassis
with two 4-40 x ¼” flat head screws.
At this time drill out the center holes on your servo
saver (not supplied) for two Nickel Teflon ball studs.
Secure them with two 3/16 alloy lock nuts.
You have two sets of servo mounting holes in the
chassis. They let you achieve proper linkage
geometry whether you run your ball studs in front of
the servo saver as shown or behind them. This is a
valuable tuning option as the servo’s weight has a big
effect on chassis weight distribution.
Locate two titanium turnbuckles and four black ball
cups. Assemble them as shown and adjust them to
an over all length of 2.375” (60.5mm). This is a
starting point. You will need to reset their length after
setting your camber in order to achieve the desired
amount of front toe.
Note:
You can use the same plastic bag trick mentioned in
Step 19 to remove play in your steering linkage.
Remember you want to remove play but still have
totally free movement in the links. Any friction at all is
unacceptable and will make you car not center
properly after steering inputs
Install your body posts with two 4-40 x 3/8” flat head
screws in the front and two 4-40 x ¼” button head
screws in the rear..
