TQ2.4GHZ RADIO SYSTEM PRECAUTIONS
Do not kink the antenna wire. Kinks in the antenna wire will
reduce range.
Do not cut the antenna “stinger” or any other part of the antenna
wire. Cutting the antenna will reduce range.
Extend the antenna as far as possible for maximum range. It is not
necessary to extend the antenna wire out of the body, but wrapping
or coiling the antenna wire should be avoided.
Do not allow the antenna wire to extend outside the body without
the protection of an antenna tube, or the antenna wire may incur
crash damage that could reduce range.
RADIO SYSTEM TERMINOLOGY
Please take a moment to familiarize yourself with these radio-
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 TQ2.4GHz system
automatically selects and locks onto an open frequency, and offers
superior resistance to interference and “glitching.”
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 4AA batteries in the model.
Frequency band
- The radio frequency used by the transmitter to
send signals to your model. Some Traxxas RTR models operate
on a 27 MHz frequency band. This model operates on the 2.4GHz
digital spread spectrum system.
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 and is included with your model.
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 Revo that operate the throttle, shift
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.
