RADIO SYSTEM ADJUSTMENTS

 Throttle Neutral adjust

The throttle neutral adjustment 
is located on the transmitter 
face and controls the forward 
and reverse travel of the throttle 
trigger. There are two settings, 
50/50 which allows equal travel 
for both forward and brake, and 
70/30 which allows more travel 
for throttle and less for brake. 
Change the adjustment by 
pressing the button and sliding it to the desired position. 70/30 is 
the recommended setting while running the Nitro Sport. 

Servo Reversing Switches

On the front of the transmitter there are two switches. One for 
throttle and one for steering. Moving the switches reverses the 
direction of the corresponding servos. For example, if you turn your 
steering wheel right and the model moves left, then switch the 
steering servo reversing 
switch to correct the 
servo direction. You 
may need to adjust 
the corresponding 
trim control after 
moving the servo-
reversing switch.

INSTALLING RECEIVER BATTERIES

The receiver battery holder is located 
underneath the battery cover. Remove 
the battery cover by removing the 
two body clips from the posts on both 
sides of the battery holder. 
Install 4 AA batteries into the battery 
holder. Alkaline batteries should be 
used. Place the 
battery holder into 
the battery cover 
with the cushioning 
foam. Secure the 
battery cover to the 
chassis using the two 
body clips as shown. 

ANTENNA SETUP

Locate the plastic tube and the 
antenna tip (supplied in the bag 
with your instructions). Insert the 
black antenna wire, extending 
from the receiver housing, into 
one end of the tube and push it all 
the way through. Spray the wire 
with glass cleaner to make it easier 
to insert. Insert the tube into the antenna mount on the side 
of the chassis. Fold the remaining antenna wire over the top 
of the antenna tube and secure it with the vinyl antenna tip. 

Under no circumstances should you ever cut your antenna wire. 

Its length is specially tuned to the frequency band, and cutting it 
could severely shorten the radio’s range. On the transmitter, 

fully 

extend

 the chrome telescopic antenna.

RADIO SYSTEM OPERATION

Your radio system was pre-adjusted before it left the factory, however, 
the adjustment should be checked prior to running the truck. 

1.

 Before you ever turn your radio system on, you must “clear” your 

frequency. There are six different channels numbered 1 through 6. 
Each of the six channels is represented by a color.  Look at the crystal 
in the back of the transmitter to determine which of the channels 
your truck is operating. Clearing your frequency means checking to be 
sure that no one else in the area is operating on the same channel. 

2. always turn the transmitter 

on first and off last.

 This 

will prevent the model from 
receiving stray signals and 
running out of control. Slide the 
transmitter switch to the “on” 
position. A steady red light should

 

illuminate. 

a flashing red 

light indicates weak batteries

.

 Weak batteries will limit the range 

of the radio signal between your transmitter and receiver. Loss of 
the radio signal can cause you to lose control of the truck. 

3. 

Turn the truck on. The  

switch is located on the 
chassis. The servos should 
jump and move to their idle 
(neutral) positions. 

4. 

With the front wheels 

off the ground, operate 
the steering control 
on the transmitter 
(channel 1). Check for 
rapid operation of the 
steering servo and that 
the steering mechanism 
is not loose or binding. 
If the servo operates 
slowly, check for weak 
batteries. Turn the 
“steering trim” control on the transmitter to adjust the servo so 
that the front wheels are pointing straight ahead. Check to be 
sure that the wheels do not turn more in one direction than in 
the other. 

5.

 Operate the throttle trigger on the transmitter to ensure that 

the throttle servo is operating properly. When the servo is 
in the neutral position, the carburetor should be in its idle 
position (you will adjust the engine idle speed later). When the 
throttle trigger is pulled all of the way, the carburetor should 
be in the fully-open position. When the throttle lever is pushed 
forward, the brake should be locked and the throttle should 
not close any further than when at idle.

RANGE TEST THE RADIO  

There are many things such as buildings, power lines, radio 
transmitters, etc. which can adversely affect the performance of 
your radio system. To make sure you do not have a “runaway” 
model, range test the radio system. With the radio system on and 
working, hold the truck and have a friend carry the transmitter 
away from you the distance you plan to run the truck.  Have the 
friend operate the controls on the transmitter to be sure that 
everything is working at full range.

NOTE: 

Never turn the transmitter or receiver off while the engine is 

running. The model could run out of control. (The on/off switch 

only turns the receiver on and off. It does not turn off the engine.)
