Motor Noise Suppression
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.
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 con-
trol.
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 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.
