TRAXXAS TQ 2.4GHz RADIO SYSTEM
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.
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.
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
0°
0°
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
