Applying the Decals

The main decals for your
model have been applied at
the factory. The decals are
printed on self-adhesive clear
mylar and are die-cut for easy
removal. Use a hobby knife to
lift the corner of a decal and
lift it from the backing.

To apply the decals, place
one end down, hold the
other end up, and gradually
smooth the decal down with
your finger as you go. This
will prevent air bubbles.
Placing both ends of the
decal down and then trying
to smooth it out will result
in air pockets. Look at the
photos on the box for typical
decal placement.

INTRODUCTION

Your model includes the latest Traxxas TQi 2.4GHz transmitter with
Traxxas Link

™ Model Memory. The transmitter’s easy-to-use design

provides instant driving fun for new R/C enthusiasts, and also offers
a full compliment of pro-level tuning features for advanced users
– or anyone interested in experimenting with the performance of
their model. The steering and throttle channels feature adjustable
Exponential, End Points, and Sub-Trims. Steering and braking Dual
Rate are also available. Many of the next-level features are controlled
by the Multi-Function knob, which can be programmed to control
a variety functions. The detailed instructions (page 31) and Menu
Tree (page 34) included in this manual will help you understand and
operate the advanced functions of the new TQi radio system. For
additional information and how-to videos, visit Traxxas.com.

RADIO AND POWER SYSTEM TERMINOLOGY

Please take a moment to familiarize yourself with these radio and
power system terms. They will be used throughout this manual.
A detailed explanation of the advanced terminology and features
of your new radio system begins on page 31.

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 TQi system
automatically selects and locks onto an open frequency, and offers
superior resistance to interference and “glitching.”

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.

Brushless Motor - A D/C brushless motor replaces the brushed

motor’s traditional commutator and brush arrangement with
intelligent electronics that energize the electromagnetic
windings in sequence to provide rotation. Opposite of a brushed
motor, the brushless motor has its windings (coils) on the
perimeter of the motor can and the magnets are mounted to the
spinning rotor shaft.

Cogging - Cogging is a condition sometimes associated with

brushless motors. Typically it is a slight stutter noticed when
accelerating from a stop. It happens for a very short period as
the signals from the electronic speed control and the motor
synch with each other.

Current - Current is a measure of power flow 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 flowing
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 efficiently 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. This model operates on the 2.4GHz
direct-sequence spread spectrum.

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.

LiPo - Abbreviation for Lithium Polymer. Rechargeable LiPo

battery packs are known for their special chemistry that allows
extremely high energy density and current handling in a
compact size. These are high performance batteries that require
special care and handling. For advanced users only.

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.
