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.

INTRODUCTION

Your model includes the TQ 2.4GHz transmitter. When powered 
on, the TQ 2.4GHz will automatically locate and lock onto an 
available frequency, allowing multiple models to be raced together 
without frequency conflicts. Just switch on and drive! The included 
TQ 2.4GHz radio system has been programmed for your model 
at the factory and does not require adjustment, but it does have 
settings you may need to access to maintain proper operation of 
your model. The detailed instructions (page 16) included in this 
manual will help you understand and operate the functions of the 
new TQ 2.4GHz radio system. For additional information and how-

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.

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 XL-5 HV 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.

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, which 
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. 

Servos 

- Small motor units in your model that operate the steering 

and throttle mechanisms.

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 steering trim knob on the face of 
the transmitter.
