INTRODUCTION
Your model includes the TQ 2.4GHz transmitter. When powered
on, the TQ will automatically locate and lock onto an available
frequency, allowing multiple models to be raced together without
frequency conflicts. Just switch on and drive! The included TQ
2.4GHz radio system has been programmed for your model at the
factory and does not require adjustment, but it does have settings
you may need to access to maintain proper operation of your
model. The detailed instructions (page 11) included in this manual
will help you understand and operate the functions of the new
TQ 2.4GHz radio system. For additional information and how-to

RADIO SYSTEM TERMINOLOGY
Please take a moment to familiarize yourself with these radio and
power system terms. They will be used throughout this manual.
2.4GHz Spread Spectrum
– This model is equipped with the
latest R/C technology. Unlike AM and FM systems that require
frequency crystals and are prone to frequency conflicts, the TQ
2.4GHz system automatically selects and locks onto an open
frequency, and offers superior resistance to interference and
“glitching.”
Current
– Current is a measure of power flow through the
electronics, usually measured in amps. If you think of a wire as a
garden hose, current is a measure of how much water is flowing
through the hose.
Frequency band
– The radio frequency used by the transmitter to
send signals to your model. This model operates on the 2.4GHz
direct-sequence spread spectrum.
mAh
– Abbreviation for milliamp hour, a measure of the capacity
of the battery pack. The higher the number, the longer the
battery will last between recharges.
Neutral position
– The standing position that the servos seek
when the transmitter controls are at the neutral setting.
NiCad
– Abbreviation for nickel-cadmium. The original
rechargeable hobby pack, NiCad batteries have very high
current handling, high capacity, and can last up to 1000
charging cycles. Good charging procedures are required to
reduce the possibility of developing a “memory” effect and
shortened run times.
NiMH
– Abbreviation for nickel-metal hydride. Rechargeable
NiMH batteries offer high-current handling and much greater
resistance to the “memory” effect. NiMH batteries generally
allow higher capacity than NiCad batteries. They can last up to
500 charge cycles. A peak charger designed for NiMH batteries is
required for optimal performance.
Receiver
– The radio unit inside your model that receives signals
from the transmitter and relays them to the servos.
Servos
– Small motor units in your model that operate the steering
and throttle mechanisms.
Transmitter
– The hand-held radio unit that sends throttle and
steering instructions to your model.
Trim
– The fine-tuning adjustment of the neutral position of the
servos, made by adjusting the steering trim knob on the face of
the transmitter.
2-channel radio system
– The TQ radio system, consisting of the
receiver, the transmitter, and the servos. The system uses two
channels: one to operate the throttle and one to operate the
steering.
RADIO SYSTEM PRECAUTIONS
• Do not kink the receiver antenna wire. Kinks in the antenna wire
will reduce range.
• DO NOT CUT any part of the receiver antenna wire. Cutting the
antenna will reduce range.
• Extend the antenna wire in the model as far as possible for
maximum range. In doing so, the antenna wire will be extended
outside of the vehicle body. Do not wrap or coil the antenna wire
to keep it from extending out of the body.
• The antenna wire must be installed into the antenna tube to
protect it from getting cut or damaged, which will reduce range.
When installing the antenna wire into the antenna tube, be
careful not to kink the wire by pressing it against the antenna
tube cap. The antenna wire should extend to just below or to
within one-half inch below the cap.
