RADIo SYSTEM TERMInoloGY
Please take a moment to familiarize yourself with these radio-
system terms. They will be used throughout this manual.
5-Cell Pack
– Another term for RX Pack or rechargeable receiver pack.
The RX pack is made up of five rechargeable NiMH battery cells and
is used in place of the 4AA batteries in the model.
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 flag 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.
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.
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.
RX Pack
- RX is a common abbreviation for the radio receiver and
items associated with it. RX Pack denotes the optional rechargeable
battery pack used to power the radio system in the model. It is
available as Traxxas part number 3037.
Servos
- Small motor units in your Slayer that operate the throttle and
steering 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 throttle and steering trim sliders on
the face of the transmitter.
