Step 42. Turn your transmitter switch on followed by the receiver switch (or plug in the extension wire if not using a switch).
Step 43. Move the transmitter throttle control to full throttle. The throttle servo should open the carbuertor and push backward on the brake
lever. If the servo rotates the wrong direction, refer to your radio manufacturer's instructions for reversing the servos.
Step 44. With the throttle control on the transmitter in the neutral position and the trim centered, check that the carburateor opening is in the
fully closed position, and that the springs (194)(196) on the throttle wire (191)(203) are compressed the same amount. If the carburetor is not
fully closed, or one spring (194)(196) is compressed much more than the other, adjust the position of the over-ride slider (195) by moving the
collars (192) along the wire (191)(203), one at a time, until the slider (195) is centered between the springs (194)(196), and the carburetor is in the
closed position. This will be the correct idle position.
Step 45. With the throttle still in the neutral position and the carburetor fully closed, check to see that the collar (192) at the front of the brake
over-ride slider (195) is not touching the slider (195). If it is, loosen the setscrew (193) and move the collar forward so that it does not touch the
over-ride slider (195) while the brake lever (102) rests in the forward position against the brake caliper. Loosen the setscrew (193) in the collar
(192) at the rear of the brake linkage wire (197) and move the collar (192) until the linkage spring (196) has a slight amount of pre-load on it.
Tighten the setscrew (193) in this collar (192).
*NOTE: This collar can be adjusted later to change the amount of "panic", or full brake that the truck has.
Step 46. Loosen the setscrew (193) in the collar (192) at the front side of the brake over-ride slider (195) and move the collar (192) until it just
touches the slider (195). Tighten the setscrew (193) in the collar (192). This will be the final location of this collar (192).
Step 47. Move the throttle control on the transmitter to full throttle. Refer to the radio manufacturer's instructions and adjust the end point
adjustment so the throttle servo will rotate just far enough to open the carburetor all the way. Now move the throttle control on the transmitter
to full brake. Adjust the end point on the transmitter so that the servo doesn't over-rotate when applying full brake. The servo should only have
to move 3/8" in the brake direction.
*NOTE: If your radio system does not have end point adjustments, you may need to move the throttle pivot and brake linkage wire to a
different hole in the servo horn. The closer the wires are mounted to center on the horn, the less the wires will move. If the wires are moved
to a different hole in the servo horn, start the throttle linkage adjustment again at Step 43.
