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 rear shock
tower.
3. Position the model 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, check for weak 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. When the throttle
trigger is pushed all the way forward, the brake should lock.
7. Once adjustments are made, turn off the receiver on your
model, followed by the hand-held transmitter.
The TQ 2.4GHz 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 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
far end, so you drive the model toward and past your position. In
addition to maximizing the radio's range, this technique will keep
your model closer to you, making it easier to see and control.
No matter how fast or far you drive your model, always leave
adequate space between you, the model, and others. Never
drive directly toward yourself or others.
TQ 2.4GHz Binding Instructions
For proper operation, the transmitter and receiver must be
electronically 'bound.' This has been done for you at the factory.
Should you ever need to re-bind the system or bind to an
additional transmitter or receiver, follow these instructions. Note:
the receiver must be connected to a 4.8-6.0v (nominal) power
source for binding and the transmitter and receiver must be within
5 feet of each other.
1. Press and hold the SET button on the transmitter.
2. Turn on the transmitter and release the SET button. The status
LED will flash red slowly, indicating that the transmitter is in bind
mode.
3. Press and hold the LINK button on the receiver.
4. Turn on the vehicle and release the LINK button. The LED on the
receiver will flash red, indicating that the receiver is in bind mode.
5. When the LEDs on both the transmitter and the receiver turn solid
green, the system is bound and ready for use. Confirm that the
steering and throttle operate properly before driving your model.

See this page for more information
on binding.
Put new batteries in the transmitter.
See page 4 for more information.
Transmitter and receiver are no longer
bound.Turn the system off and then
back on to resume normal operation.
Find source of the link failure (i.e., out of
range, low batteries, damaged antenna).
Notes
See page 4 for information on how to
use your transmitter controls.
See this page for more information
on binding.
Consistent low voltage in the receiver
triggers Fail Safe so that there is
enough power to center the throttle
servo before it completely loses power.
