Servo Mounting continued... (JR sized servos) -
When using servos such as the JR 3650, JR Sport MN48, Hitec 225MG,
Spektrum 5030/5040, and others with this case design, you will need to
remove the servo mounting ears on the side of the case furthest from the
servo spline with a hobby knife or rotary tool (refer to diagram above and to
the left).
Once you have removed the ears from the one side of the servo, bolt the red
aluminum servo mount [109] to the remaining ear with a 4-40 x 1/4” button
head screw [26] and a servo mount washer [110]. Before bolting the servo
down with a 4-40 x 5/16” flat head screw [12], place a piece of doubled sided
servo tape on the bottom of the servo. Peel the backing off of the tape, but do
not stick it down until you get the flat head screw started in the red aluminum
mount so that you know it will line up with the hole. Now you should be able
to stick the servo down and finish tightening the flat head screw.
After the servo has been bolted down and the servo saver has been installed,
you can pop the tie rods onto the servo saver and steering blocks.
Tie-Rods
Start by assembling 2 tie rods as shown to the left. This 1.126” gap
should be a good starting point for toe-in adjustment. If you do not have a
set of calipers, you can line up your tie rods with the drawing on the page
to get you close. Either way, you will need to adjust the final length after
the car is fully ready to run.

Servo Mounting -
If installing an Airtronics/Sanwa 94761 or SRGHR, then continue with the following
instructions and the picture on the right.
If installing a JR 3650, JR Sport MN48, Hitec 225MG, Spektrum 5030/5040, then refer to the
diagram and instructions on the bottom of the page.
When installing the above referenced Sanwa Servos, insert two 4-40 x 5/16” screws [12] up
through the chassis, then slide a Thin Ride Height Spacer [108] over each screw before
sliding the servo down over the screws and securing in place with two 4-40 red lock nuts [9].
After the servo has been bolted down and the servo saver has been installed, you can pop
the tie rods onto the servo saver and steering blocks.

Servo Saver Assembly -
Install the servo saver (not included) and assorted hardware in the order shown to the right. Put
the 4-40 x 3/8” button head screws [24] through the narrower set of holes on the servo saver
brace [107] and the middle set of holes on the servo saver as shown. The holes in the servo
saver will need to be either drilled out, or can be reamed out carefully with a hobby knife by lightly
setting the tip of the blade in the hole and spinning it as if it were a drill bit. Do this a little at a time
from both sides until the screw will pass through the hole. Once you have the screws through the
servo saver brace and servo saver, tighten the red low-profile balls [11] onto the screws.
