Throttle reversing procedure:

1.   Press and hold the SET button on the transmitter for two 

seconds. The status LED will flash green.

2.   Move and hold the throttle trigger to the full forward or full 

brake position.

3.   While holding the throttle trigger in position, press the SET 

button to reverse the channel.

4.   The channel is now reversed. Confirm correct servo operation 

before running your model.

Warning

: Changing the direction of the throttle servo will also 

change its neutral position. Be certain to confirm the throttle servo 

properly closes the engine’s throttle opening when the transmitter’s 
trigger is at neutral. 

USING THE RADIO SYSTEM

The TQ 2.4GHz Radio System has been adjusted at the factory for 
correct operation with your model. The adjustment should be 
checked before running the model, in case of movement during 
shipping. Follow these steps:

1.   Turn the transmitter switch on. The status LED on the 

transmitter should be solid green (not flashing).

2.  Turn on the receiver switch in the model. The switch is located 

on the battery compartment.

3.   Position T-Maxx so that its front wheels are off the ground.
4.   Turn the steering wheel on the transmitter back and forth  

and check for rapid operation of the steering servo. Also, 
check that the steering mechanism is not loose or binding. If 
the steering operates slowly, then make sure you have fresh 
receiver batteries.

5.   When looking down at the 

model, the front wheels should 
be pointing straight ahead. If 
the wheels are turned slightly 
to the left or right, slowly adjust 
the steering trim control on the 
transmitter until they are pointing straight ahead.

6.   Operate the throttle trigger on the transmitter and check for 

rapid operation of the throttle servo. When the throttle trigger 
is pulled back, the carburetor should open (slide moves out). 
When the throttle trigger is pushed all the way forward, the 
brake should lock. 

7.   Operate the shift button on the transmitter and check for 

rapid operation of the shifting servo. Push the shift button 
down for forward. The servo will operate the spring-loaded 
shift mechanism and you will hear the transmission click into 
forward. Push the shift button up for reverse and you will again 
hear the transmission click and shift into gear.

8.   Once adjustments are made, turn off the receiver on your 

T-Maxx, followed by the hand-held transmitter.

Range-Testing the Radio System

Before each running session with your model, you should range-test 
your radio system to ensure that it operates properly.
1.  Turn on the radio system and check its operation as described in 

the previous section.

2.  Have a friend hold the model with the engine off.
3.  Walk away from the model with the transmitter until you reach 

the farthest distance you plan to operate the model.

4.  Operate the controls on the transmitter once again to be sure that 

the model responds correctly.

5.  Do not attempt to operate the model if there is any problem with 

the radio system or any external interference with your radio 
signal at your location.

Higher Speeds Require Greater Distance

The faster you drive your model, the more quickly it will near the 
limit of radio range. At 50mph, a model can cover 73 feet every 
second! It’s a thrill, but use caution to keep your model in range. 
If you want to see your model achieve its maximum speed, it is 
best to position yourself in the middle of its running area, not the 

TRAXXAS TQ 2.4GHz RADIO SYSTEM

The TQ transmitter has a directional antenna. For maximum 
range, hold the antenna upright and pointed in the direction 
of the model. Pointing the transmitter away from the model 
will reduce radio range.

Always use the idle speed 
adjustment screw (

see page 21

on the carburetor (

see page 15

) to 

adjust the engine idle speed.
