Warning
Servo Throw
Operate each servo over its full stroke and be sure the linkage does not bind or come loose.
The continuous application of unreasonable force to a servo may cause damage and excessive battery drain.
A whining noise indicates that the
steering servo is improperly set.
Adjust the steering servo so that unreason-
able force is not applied to the servo by the
chassis at maximum servo travel.
Electronic Speed Control
Install the heat sinks where they will not come in contact with aluminum, carbon fiber or other parts that
conduct 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.
Motor Noise Suppression
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 a 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 contact due to vibration emits a high-frequency noise that affects the performance of the receiver. An operation
may become unstable, the range may be narrowed, or control may be lost.

Caution!
Decide the EPA value at the
contact point.
