A.1 Installation of P06 into the Chassis
A.1.1
Install the qty4 P06 into the chassis individually. Light filing of the edges of the designated holes in the
chassis may be required for easier installation; where the small semi-circle intersects the larger.
Place the P06 with the larger end on a flat surface. Then take the chassis in hand so that the P06 will be
installed from the top of the chassis through to the bottom. The large end of P06 will shoulder on the
upper side of the chassis. Align the designated hole of the chassis with the P06, and push the chassis
onto the P06 piece.
The P06 will snap into place. Repeat for the remaining P06. CA glue can be used to further secure the
piece into the chassis if desired.

3
A.1.2
Install a P3x4 set screw into each of the four P06.
A.1.3
With a hobby-knife, trim off any of the P06 surpassing the bottom side of the chassis.
A.2 Install Arm Joints
Install qty8 3280 Ball Joint Balls using qty 8 C3x6 screws in the indicated diagram below. For a starting
setup, install a 1mm shim below each 3280 for a starting lower roll-center setting.

4
Snap qty 8 5040 Wishbone Inserts onto the already installed 3280’s on the chassis.
A.3 Arms
A.3.1 Wishbone Construction
Instal the 3041 Shock Mount onto the arm using a M3x8 screws to mount it from the bottom.

5
NOTE: Install one M3x3 set screw in the hole of the shock mount that is not being used. This will fix the
shock mount in position and prevent it from rotating.
Install the 3x8 set screw into the shock mount.
Install the P04 and the 3030 Roll Bar Mount to the 1100 Lower Wishbone with qty2 B2.5x6, respectively.
Install the P3x6 into the 3030, and then install the 3281 Ball onto the P3x6.

6
A.3.2 Arm Configuration
Repeat step A.3.1 for each of the four arms.
In the front, mount the square side of the shock mount to the outside on the arm. Use the most inward
position on the arm and the outward mounting hole on the mount for the set screw to mount the shock.
In the rear, use the round part of the shock mount to the outside. Use the second widest position on
the arm holes and the outer hole for the set screw for the shock.
NOTE: Finally, install one M3x3 set screw in the hole of the shock mount that is not being used. This will
fix the shock mount in position and prevent it from rotating.
A.3.3 Arm Installation
Then, install each of the four lower arms and secure them with qty2 5050 C-Clip For Wishbones per each
lower arm, as seen above.

7
A.4 Bulkheads
Install the 4 bulkheads to the chassis by using qty2 C3x6 for each.

8
The 7000 Center Weight has four possible mounting screws. The flex of the lower chassis varies
depending on which screws are installed. Install with qty2 C3x6 screws.

B.1.2 Front Dual Joint Driveshaft
Construct the front axles and the driveshaft bone halves first, to
then join them with ST17.
Use a flat-head with a width of 2.6 mm in the slot of the ST17 to
pry it open and gain clearance to install the two halves of the
driveshaft.

Assemble the first front upright as depicted by the diagram.
Notes:
-Upper outer roll center can be adjusted with different shim sizes below the ST03.
Recommended starting setup is 1mm.
-Roll Center and track-width can also be varied using various shim sizes between the 3190 and
ST03. Recommended starting setup is 1.0 mm.
-Bump steer can also be adjusted by varying the shim size on the steering connection of the arm.
Replicate the other front upright sub-assembly for the opposite side. Thus, flip the GZ11701 and build as
depicted above.

C.1.3 Installation of Uprights and Driveshafts
Install the front and rear drive shafts into the front and rear uprights, respectively. Then install the
uprights into the lower wishbones and tighten down each of P04 to clamp onto the ST03’s. Later, we will
explain the necessary tightness needed on the PO4 for free movement.

15
NOTE: Once the drive shafts are inserted into their respective uprights, install the small plastic retaining
ring onto the driveshaft until it is flat with the hex.

E.1 Spool
Light sanding of the spool on the two outer diameters where the 6010 bearings sit will aid in smooth
assembly.
Must install the 6010 bearings before the GZ11705 Outdrives.
E.2 Rear Differential
Light sanding on the outer diameters where the 6010 bearings sit of the left and right differential
housings will aid in smooth assembly.
Must install the 6010 bearings before the GZ11705 Outdrives. You also need to install 8020 and 964050,
before you install 4050.
