Note Step C-2: To properly shim the di, start by test tting the di with no shims and check for

side to side play. If no (or very little) play is present, then continue on to the next step. If you feel

excessive side to side play, then start by adding one shim on the gear side of the di assembly. This

will move the mesh tighter and remove any play. If the mesh is too tight at this point, move the shim

to the other side. In some rare cases, two shims may be necessary.

Note: The front and rear of

the car use dierent inner

bulkheads.

The front is angled

whereas the rear is

only slightly angled.

Changes to the wheelbase have a dramatic eect on handling,

since it shifts the distribution of weight over the rear wheels.

This adjusts traction. By shortening the wheelbase at the rear, you

are placing more weight over the rear wheels.

Changes to the wheelbase also change the amount of sweep the
rear driveshaft will have. More driveshaft sweep creates an eect

similar to anti-squat, where the rear end gets pushed upwards on

throttle. This helps reduce chassis slap when landing jumps on throttle.

DO NOT SKIP THIS STEP!

Note: The TKR1601 set screws are meant to keep the TKR8042 screws from coming loose. After installing TKR8042
and ensuring the steering action is free, install TKR1601 in the locations indicated. Very slowly tighten the screws

until you feel some resistance from contacting the TKR8042 screws. DO NOT OVERTIGHTEN. Also be sure to loosen

TKR1601 before unscrewing TKR8042 or you will damage the screws and the parts.

M3x8mm Washer

Note: The steering stops provide adjustable

travel limiters to control overall steering throw.

We recommend 1 washer on each side.

With too much steering travel,

the rear end will lose traction around

corners, the vehicle will be very hard to drive

and it will be more prone to breaking parts.

Shock Filling Instructions

For both front and rear shocks

Step 1. Insert all four larger o-rings into the emulsion caps and set aside. Install the small o-rings onto the
small emulsion screws by placing the o-rings on a pit mat or towel and pressing the screws into the o-rings.

Step 2. Fill shock with oil all the way to the top and pump the shock shaft up and down 3-5 times.

Step 3. Screw on the cap all the way tight (shock tool TKR1115 is helpful in tightening completely).

Step 4. With the shock at about a 45° angle, push and hold the shock shaft to the top and insert the

prepared emulsion screw/seal. Oil will leak out during this process. Tighten the screw until snug
(do not overtighten).

Step 5. Pump the shock shaft up and down about 30 times vigorously. This emulsies the oil.

Step 6. With the shock shaft fully extended, remove the emulsion screw from the cap to do the nal bleed.

Step 7. With the shock at about a 45° angle, push and hold the shock shaft to the top and insert the

prepared emulsion screw/seal again. Oil will leak out during this process. Tighten the screw until snug
(do not overtighten).
