Radio System Terminology - Traxxas T-Maxx 4910 Owner's Manual

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.
Frequency Flag
Channel
Band Color
1 26.995 Brown
2 27.045 Red
3 27.095 Orange
4 27.145 Yellow
5 27.195 Green
6 27.255 Blue
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 "RX" 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 T-Maxx. All Traxxas RTR models operate on a 27 MHz
frequency band.
mAh – Abbreviation for milliamp hour. 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

capacity than NiCad batteries. They can last up to 500 charge

cycles. A peak charger designed for NiMH batteries is required

2033
Receiver - The radio unit inside your T-Maxx that receives signals from
the transmitter and relays them to the servos.
2034
2035
RX Pack - RX is a common abbreviation for the radio receiver and
items associated with it. RX Pack denotes the optional rechargeable
2036
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 T-Maxx that operate the throttle
and steering mechanisms.
Three-channel radio system - The TQ-3 radio system, consisting of
the receiver, the transmitter, and the servos. The system uses three
channels: one to operate the throttle, one to shift the transmission,
and one to operate the steering.
Transmitter - The hand-held radio unit that sends throttle and
steering instructions to your T-Maxx.
Trim - The fine-tuning adjustment of the neutral position of the servos,
made by turning the throttle and steering trim knobs on the face of
the transmitter.
