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.

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.

Note: If building the side-rail version of the car, we recommend going to page 46 of the manual at this

point. The screws to install the side-rail are easier to install before the upper-arm installation.

Place the steering rack onto the 3090 piece, and then secure it into its general position using the bearings as depicted in the image above. Next we will adjust the slop in the system by installing the P3x5 set screw in the back (a thread locker is recommended here).

Tighten the set screw until slop of the rack between the bearings is eliminated. However, do not overtighten; you want the rack to be able to slide side-to-side under its own weight.

There will be a small break in period for this, so regularly check the fitment of the rack and tighten the set screw as play develops.

Pictured are the Stand Shock towers for front (1122) and rear (1123), respectively.

For the Low Profile shocks, use front (1124) and rear (1125) towers.

For Ultra Low Profile shocks, use front (1126) and rear (1127) towers.

I.4 Rear Body Posts

Install the rear body posts to the rear shock tower using one B3x6 screw for each.

The Piston of the shock must be secured to the shaft using the two E-Clips; one on each side. Then the shaft can be passed through the Shock Body. Before installing the lower plastic pivot piece to the shaft, it is necessary to install the O-Ring, Plastic Retainer, and Lower Aluminum Shock Cap around the Shaft and onto the lower part of the Shock Body. Then the Universal Ball can be installed; install it from the shiny side of the plastic.
