TRAXXAS TQ 2.4GHz RADIO SYSTEM
Throttle reversing procedure:
Note
: Throttle reversing is often times unnecessary on electric
models, as issues with the throttle can usually be solved by
reprogramming the speed control and/or verifying that the motor
is wired correctly. Before attempting to reverse the throttle channel
using the procedure below, you should first recalibrate the speed
control. Refer to “XL-5 Setup Programming” on page 14.
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 (it does not matter which position you choose).
3. While holding the throttle trigger in position, press the SET button
to reverse the channel.
4. The channel is now reversed. Recalibrate the speed control and
then confirm correct servo operation before running
your model.
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. Here’s how:
1. Turn the transmitter switch on. The status LED on the transmitter
should be solid green (not flashing).
2.
Elevate the model so that the rear tires are off the ground.
If you are holding the model, grip it firmly. Make sure your hands
are clear of the moving parts of the model.
3. Plug the battery pack in the model into the speed control.
4. Press and release the EZ-Set button on the speed control to turn
the model on. The speed control’s LED will glow red. To turn the
speed control off, press the EZ-Set button until the LED turns off.
Note
: If the LED shines green after the speed control is turned
on, Low-Voltage Detection is activated. This may cause poor
performance from NiMH battery packs. Make sure to turn the
Low-Voltage Detection on when using LiPo batteries.
Never use
LiPo batteries while Low-Voltage Detection is turned off.
See
page 14 for more information.
5. 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, check for weak batteries.
6. 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.
7. Operate the throttle trigger to ensure that you have full forward
and reverse operation, and that the motor stops when the
throttle trigger is at neutral.
8. Once adjustments are made, turn off your model, 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. Make sure hands and clothing are
clear of the wheels and other moving parts on the model.
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.
Using Reverse: While driving,
push the throttle trigger
forward to apply brakes.
Once stopped, return the
throttle trigger to neutral.
Push the throttle trigger
forward again to engage
proportional reverse.
The TQ 2.4GHz transmitter has a directional antenna. For
maximum range, hold the transmitter upright and pointed
in the direction of the model. Pointing the transmitter away
from the model will reduce radio range.
