Assembly Safety Precautions

Warning
Connector Connections
Be sure the receiver, servo and bat-
tery connectors are fully and firmly
connected.
If vibration from the model cause a connector to work
loose while the model is in operation. You may lose
control .
Receiver Vibration Damping and
Waterproofing
(Car)
Dampen the vibration to the receiver
by mounting to the chassis or mount-
ing plate with thick double sided tape
in electric powered models. In gas
powered models wrap the receiver in
foam and mount it where the vibration
is the least prevalent.
(Boat)
Dampen the vibration to the receiver
by wrapping it in foam. Waterproof by
placing it in plastic bag or watertight
radio box in model.
If the receiver is subjected to strong vibration or shock
erratic or loss of control may occur. If any moisture
comes in contact the receiver and servos you may
expertise the same result as well as damage to the
system.
Receiver Antenna
Do not cut or bundle the receiver an-
tenna
Do not bundle the receiver antenna
together with the servo lead wires
Keep the receiver antenna at least 1
inch away from the motor and battery
and wires that handle heavy current
loads..
Cutting, bundling or routing the receiver antenna near
any devise that produce noise will reduce the operat-
ing range of the system and result in loss of control.
*Also route the receiver antenna away from metal,
carbon fiber and other parts that conduct electric-
ity. These parts can transmit high frequency noise.
Electronic speed control
Install the heat sinks where they will
not come in contact with aluminum,
carbon fiber or other parts that con-
duct electricity.
If the FET Amp (Electronic speed control) heat sinks
touch other materials that conduct electricity a short
circuit could occur. This could result in loss of control
and damage to the system.
Servo Throw
Operate each servo over its full stroke
and be sure the linkage does not bind
or is loose.
The continuous application of unreasonable force to a
servo may cause damage and excessive battery
drain.
Servo Installation
When you install the servos always
use the rubber grommets provided in
servo hardware bags. Mount the ser-
vos so they do not directly come in
contact with the mount.
If the servo case comes in direct contact with the
mount vibration will be directly transmitted to the
servo.
If this condition continues for a long time the servo
may be damaged and control will be lost.
Motor Noise Suppression
Always install capacitors to suppress
noise when electric motors are used.
If capacitors are not properly installed you could ex-
perience erratic operation and reduced range as well
as loss of control.
Other Noise Suppression Methods
Be sure there are no metal parts in
your model which under vibration can
come in contact with other metal
parts.
Metal to metal contacts under vibration will omit a high
frequency noise that will effect the receivers perfor-
mance. You could experience erratic operation and
reduced range as well as loss of control.
