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 ow of current through it.
When ow is constricted, energy is converted to heat and is lost.
The Velineon power system is optimized to reduce electrical
resistance and the resulting power-robbing heat.
Rotor - The rotor is the main shaft of the brushless motor. In a
brushless motor, the magnets are mounted to the rotor, and the
electromagnetic windings are built into the motor housing.
Sensored - Sensored refers to a type of brushless motor that
uses an internal sensor in the motor to communicate rotor
position information back to the electronic speed control. The
VXL-3s electronic speed control is able to use sensored motors
when applications benet from them (such as some sanctioned
racing classes).
Sensorless - Sensorless refers to a brushless motor that uses
advanced instructions from an electronic speed control to
provide smooth operation. Additional motor sensors and
wiring are not required. The VXL-3s electronic speed control is
optimized for smooth sensorless control.
Servo - Small motor unit in your model that operates the steering
mechanism.
Solder Tabs - Accessible, external contacts on the motor that
allows for easy wire replacement. The Velineon 3500 is equipped
with solder tabs.
Transmitter - The hand-held radio unit that sends throttle and
steering instructions to your model.
Trim - The ne-tuning adjustment of the neutral position of the
servos, made by adjusting the throttle and steering trim sliders
on the face of the transmitter.
Thermal Shutdown Protection - Temperature sensing electronics
used in the VXL-3s electronic speed control detect overloading
and overheating of the transistor circuitry. If excessive
temperature is detected, the unit automatically shuts down to
prevent damage to the electronics.
2-channel radio system - The TQ radio system, consisting of
the receiver, the transmitter, and the servos. The system uses
two channels: one to operate the throttle and one to operate
the steering.
Voltage - Voltage is a measure of the electrical potential difference
between two points, such as between the positive battery terminal
and ground. Using the analogy of the garden hose, while current is
the quantity of water ow in the hose, voltage corresponds to the
pressure that is forcing the water through the hose.

Use the Right Charger
The most convenient type
of charger is an AC peak-
detecting charger that plugs
directly into an AC wall
outlet. It contains special
peak-detection circuitry
that automatically shuts the
charger off when the battery
is fully charged.
If you’re using a 15-minute
timed charger, always fully
discharge NiMH battery
packs before each charge.
Some high mAh battery
packs (1500 mAh or higher)
require more than the
standard 15 minutes of
charge time. If the battery
pack is cold after 15 minutes
of charging, add another
5 minutes of charge time.
Closely monitor the battery
pack and stop charging
when it begins to feel
warm to the touch. Never
leave a battery charging
unattended. Always follow
charger manufacturer’s
instructions.
For Lithium Polymer batteries,
only use a charger designed
for LiPo batteries. See LiPo
battery warnings on page 4.
