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 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

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.
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.
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 EVX-2
uses MOSFET power transistors 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.
550 and 540
- These numbers refer to the size of the motor. 550
motors have armatures that are 30% longer than 540 motors.
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.
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.
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.
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.
Servo
- Small motor unit in your model that operates the steering
mechanism.
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 knobs
on the face of the transmitter.
Note:
The Multi Function knob
must be programmed to serve as a throttle trim adjustment.
