Before proceeding, become familiar with the operation of your radio system. Refer to your operation manual and become famil-

iar with the End Point Adjustment (EPA) or Travel Adjustment for throttle, brake, and all trim adjustments.

Brake Disc and Pad Set-up

Proper brake pad to disc clearance is essential for optimal

braking performance, use this method for initial set-up and

maintenance and to check the presets from the factory. Due to

normal brake wear, this setting should be checked after every

60-90 minutes of use.

1.With the radio tray powered off and the throttle servo arm

removed, move the brake linkage wires towards the engine to

the full throttle position.

2.Push the brake pads closed towards the center diff mount

by hand. The brake cams and linkage should not engage, if

they are engaged the pads will not compress all the way to the

center diff mount.

3.Using a 4-40 washer as a gauge, adjust the brake screw to

set the gap between the head of the screw and the brake pad

to .020 - .030” (0.5 - 0.75mm). The washer should ? t snug into

the gap. (Fig. 1)

NOTE: Removing the center diff assembly will make this adjus-

ment easier.

4.Repeat on all four brake screws.

Installing the Throttle Linkage

1.Turn on your transmitter. Adjust the throttle trim on the trans-

mitter to the neutral or centered position, this will allow for ? ne

adjustment later.

2. With the servos, receiver, swtich and charged receiver

battery installed and connected, turn on the radio tray. When

throttle is applied, ensure the servo is rotating in the proper

direction. (Fig.2)

NOTE: To change the servo rotation, locate the servo revers-

ing function on your transmitter and switch the direction of the

servo.

3.Select a servo adapter that matches the number of splines

on your servo (refer to your owners guide).

4.Place the servo arm adaptor onto the output shaft of the

servo. Aligning the throttle servo arm parallel with the side of

the servo case, place the arm onto the splines of the adaptor.

If there is a slight angle, use the trim adjustment on your radio

to position the arm as shown (Fig. 3). Secure the throttle servo

arm with the screw supplied with the servo.

NOTE: If the arm cannot be positioned as shown using trim ad-

justment, the angle can be changed by removing the arm and

adaptor and rotating the adaptor one spline in either direction

until the arm is positioned as shown (Fig. 3).

5.Snap the throttle linkage ballcup onto the carburetor ball.

The linkage should be level with the bottom of the chassis, and

NOT hitting the servo case. Test for free movement. If neces-

sary, rotate the ball/ring on the carburetor. (Fig. 4)

Installing and Adjusting your 8IGHT Throttle/Brake Linkage Before proceeding, become familiar with the operation of your radio system. Refer to your operation manual and become familiar with the End Point Adjustment (EPA) or Travel Adjustment for throttle, brake, and all trim adjustments. Brake Disc and Pad Set-up Proper brake pad to disc clearance is essential for optimal braking performance, use this method for initial set-up and maintenance and to check the presets from the factory.

6.With the air filter assembly removed from the carburetor, adjust the collar so that there is .030” (about the thickness of a #4 washer) space between the throttle actuator and adjustment collar (Fig. 5). Fig. 5 7.Watch the throttle linkage as the transmitter trigger is slowly moved to the full throttle position. Adjust the throttle EPA on the transmitter so that the carburetor only opens 90-95% of its total travel (Fig. 6).
PAGE 3
Adjusting the Brake Linkage 1. With the throttle in the neutral position, adjust the brake linkage rods as shown. Note the amount of thread showing on each brake rod.(Fig. 9) 2. Slide the collar (black) along the front brake rod (upper) towards the fuel tubing, until there is no play left in the linkage. The fuel tubing should NOT be compressed. Repeat this process for the rear brake rod (lower). NOTE: The upper adjustment rod is for the front brake and the lower for the rear brake (Fig. 10). 3.

Checking the Brake Bias Brake bias is the difference between the amount of rear and front braking pressure. 1. To check the amount of rear brake bias, place the vehicle on a table, move the trigger to the full brake position and press down on both front and only one rear wheel to keep them from rotating. 2. Lift the remaining rear wheel off the table and rotate it in the forward direction. The resistance required to rotate the wheel, is the amount of rear brake being applied.
