To prevent loss of radio range
do not kink or cut the black wire,
do not bend or cut the metal tip,
and do not bend or cut the white
wire at the end of the metal tip.

safe operation. Follow all the precautions in this manual as well as
any precautions and warnings included with your batteries before
charging LiPo batteries and installing them in your model.
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.
NiMH
- Abbreviation for nickel-metal hydride, the most common
radio-control battery type. NiMH packs have lower current
handling ability and less capacity than LiPo packs, but are generally
lower in cost and provide reliable performance.
Receiver
- The radio unit inside your model that receives signals from
the transmitter and relays them to the servos.
Resistance
- In an electrical sense, resistance is a measure of how an
object resists or obstructs the flow of current through it. When flow
is constricted, energy is converted to heat and is lost.
Rotor
- The rotor is the main shaft of the brushless motor. In a
brushless motor, the magnets are mounted to the rotor, and the
electromagnetic windings are built into the motor housing.
Sensor
– Device in the model that gathers data for telemetry such as
temperature, voltage, or RPM.
Sensored
- Sensored refers to a type of brushless motor that
uses an internal sensor in the motor to communicate rotor position
information back to the electronic speed control.
Sensorless
- Sensorless refers to a brushless motor that uses
advanced instructions from an electronic speed control to provide
smooth operation. Additional motor sensors and wiring are not
required.
Servo
- Small motor unit in your model that operates the steering
mechanism.
Telemetry
– Describes the capability for the model to provide real-
time information such as speed, temperature, RPMs, and voltage
back to the transmitter for display.
Transmitter
- The hand-held radio unit that sends throttle and
steering instructions to your model.
Traxxas Link
– iPhone/iPod touch application that provides access
to telemetry data and adjustments in the TQi radio system. Sold
separately on the App Store (Apple.com). See page 27 for more
information.
Trim
- The fine-tuning adjustment of the neutral position of the
servos, made by adjusting the throttle and steering trim knobs on
the face of the transmitter.
Note:
The Multi-Function knob must be
programmed to serve as a throttle trim adjustment.
Thermal Shutdown Protection
- Temperature sensing electronics
used in the electronic speed control detect overloading and
overheating of the transistor circuitry. If excessive temperature is
detected, the unit automatically shuts down to prevent damage to
the electronics.
Voltage
- Voltage is a measure of the electrical potential difference
between two points, such as between the positive battery terminal
and ground. Using the analogy of the garden hose, while current is
the quantity of water flow in the hose, voltage corresponds to the
pressure that is forcing the water through the hose.
IMPORTANT RADIO SYSTEM PRECAUTIONS
• For maximum range, always point the front of the transmitter
toward the model.
• Do not kink the receiver’s antenna wire. Kinks in the antenna wire
will reduce range.
• DO NOT CUT any part of the receiver’s antenna wire. Cutting the
antenna will reduce range.
• Extend the antenna wire in the model 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 get
cut or damaged, reducing range. It is recommended to keep the
wire inside the body (in the antenna tube) to prevent the chance
of damage.
