 RADIO & VELINEON POWER SYSTEM
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. 
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 benefit 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 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.
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 TQi 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 flow in the hose, voltage corresponds to the 
pressure that is forcing the water through the hose.
IMPORTANT RADIO SYSTEM PRECAUTIONS
• Do not kink the receiver’s antenna wire. Kinks in the antenna wire 
will reduce range.
• DO NOT CUT any part of the receiver’s antenna wire. Cutting the 
antenna will reduce range.
• Extend the antenna wire in the model as far as possible for 
maximum range. It is not necessary to extend the antenna wire out 
of the body, but wrapping or coiling the antenna wire should be 
avoided. 
• Do not allow the antenna wire to extend outside the body without 
the protection of an antenna tube, or the antenna wire may get 
cut or damaged, reducing range. It is recommended to keep the 
wire inside the body (in the antenna tube) to prevent the chance 
of damage.
To prevent loss of radio range 
do not kink or cut the black wire, 
do not bend or cut the metal tip, 
and do not bend or cut the white 
wire at the end of the metal tip.
