Installation Safety Precautions
ｎ Warning
Connector Connections
ｊ Be sure the receiver, servo, crystal and
connectors are fully and firmly con-
nected.
If vibration from the model causes a connector to work
loose while the model is in operation, you may lose
control .
Receiver Vibration Damping and
Waterproofing
ｊ (Car): Dampen the vibration to the
receiver by mounting to the chassis or
mounting 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.
ｊ (Boat): Dampen the vibration to the
receiver by wrapping it in foam. Water-
proof by placing it in a plastic bag or water-
tight the radio box in your 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
experience the same result as well as damage to the
system.
Receiver Antenna
ｌ Do not cut or bundle the receiver an-
tenna.
ｌ Do not bundle the receiver antenna to-
gether with the servo lead wires.
ｊ 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 device that produces noise will reduce the operating
range of the system and result in loss of control.
Also route the receiver antenna away from metal, carbon

can transmit high frequency noise.
Electronic speed control
ｊ Install the heat sinks where they will not
come in contact with aluminum, carbon
fiber or other parts that conduct electricity.
If the E.S.C. (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
ｊ 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
ｊ When you install the servos always use
the rubber grommets provided in servo
hardware bags. Mount the servos 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
ｊ Always install capacitors to suppress
noise when electric motors are used.
If capacitors are not properly installed you could
experience erratic operation and reduced range as well
as loss of control.
Other Noise Suppression Methods
ｊ Be sure there are no metal parts in
your model which under vibration could
come in contact with other metal parts.
Metal to metal contacts under vibration will emit a
high frequency noise that will affect the receiver's
performance. You could experience erratic operation and
reduced range as well as loss of control.
