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.
TRAXXAS TQ
i
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 27) and Menu
Tree (page 29) 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 27.
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.
