GRAVE DIGGER
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 23) and Menu Tree (page 25) included
in this manual will help you understand and operate the advanced
functions of the new TQi radio system. For additional information

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 23.
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.
ESC (Electronic Speed Control)
- An electronic speed control
is the electronic motor control inside the model. The XL-5
uses MOSFET power transistors to provide precise, digital
proportional throttle control. Electronic speed controls use
power more eficiently 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 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.
