Warning
Electronic Speed Cont
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 oc-
cur. 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 loss of control.

Schottky diode
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.

"-" side
Motors with no suppressor capacitors, or inade-
quate suppression, may cause the receiver to mal-
function. Always solder the capacitors supplied to
your motor.
The Schottky diode improves the efficiency of the
speed control / motor combination and provides
extra protection to the brake FETs. The white ring
must always face the positive side.
