Applying the Decals
The main decals for your model
have been applied at the
factory. Additional 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.

RADIO & VELINEON POWER SYSTEM
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 complement 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 of functions. The detailed instructions (page 29) and Menu
Tree (page 31) 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 29.
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. The VXL-3s electronic speed control is optimized
to virtually eliminate cogging.
Current - Current is a measure of power flow through the
electronics, usually measured in amps. If you think of a wire as 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. The VXL-3s electronic
speed control uses advanced circuitry to provide precise, digital
proportional throttle control. Electronic speed controls use power
more efficiently than mechanical speed controls so that the
batteries run longer. An electronic speed control also has circuitry
that prevents loss of steering and throttle control as the batteries
lose their 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. The Velineon 3500 motor is a 3500 kV motor optimized
for the best speed and efficiency in lightweight 1/10 scale models.
LiPo - Abbreviation for Lithium Polymer. Rechargeable LiPo
battery packs are known for their special chemistry, which allows
extremely high energy density and current handling in a compact
size. These are high performance batteries that require special
care and handling. LiPo battery packs are 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.
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.
