TRAXXAS
THE TRAXXAS TQ RADIO SYSTEM
Use the Right Batteries
Your transmitter uses AA
batteries. Use new alkaline
batteries, or rechargeable
batteries such as NiCad
or NiMH (Nickel Metal
Hydride) batteries in your
transmitter. Make sure
rechargeable batteries are
fully charged according
to the manufacturer’s
instructions.
If you use rechargeable
batteries in your
transmitter, be aware
that when they begin
to lose their charge, they
lose power more quickly
than regular alkaline
batteries.
Caution: Discontinue
running your model at the
rst sign of weak batteries
(ashing red light) to avoid
losing control.
RADIO SYSTEM TERMINOLOGY
Please take a moment to familiarize yourself with these radio and
power system terms. They will be used throughout this manual.
BEC (Battery Eliminator Circuit) - The BEC can either be in the
receiver or in the ESC. This circuit allows the receiver and servos
to be powered by the main battery pack in an electric model.
This eliminates the need to carry a separate pack of 4 AA
batteries to power the radio equipment.
Channel - The 27 MHz frequency band is divided into 6 channels
so that up to six models can be operated simultaneously. Each
channel is referred to by its ag color and channel number, as
shown below.
Clearing your frequency - A routine, verbal check to make sure
nobody else in your area is operating on the same channel.
Always clear your frequency by calling out your channel number
before operating your model. Wait or move to another area if
your channel is already being used.
Crystal (X-tal) - The plug-in device that determines which channel
the radio system will operate on. For each channel, there are
two crystals, one for the receiver and one for the transmitter. Of
those two crystals, the one marked with the lower number (.455
MHz lower) must be inserted into the receiver.
Current - Current is a measure of power ow through the
electronics, usually measured in amps. If you look at wire like a
garden hose, current is a measure of how much water is owing
through the hose.
ESC (Electronic Speed Control) - An electronic speed control is
the electronic motor control inside the model. Electronic speed
controls use power more efciently than mechanical speed
controls so that the battery runs longer. An electronic speed
control also has circuitry that prevents loss of steering and
throttle control as the battery loses its charge.
Frequency band - The radio frequency used by the transmitter to
send signals to your model. All Traxxas RTR models operate on a
27 MHz frequency band.
kV Rating - Brushless motors are often rated by their kV number.
The kV rating equals no-load motor rpm with 1 volt applied.
The kV increases as the number of wire turns in the motor
decreases. As the kV increases, the current draw through the
electronics also increases.
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.
