Automatic Fan Control Connection
The Elite Falcon Electronic Speed Controllers 145/200/220 contains a driven output for the external fan (5V, up to 300mA). It is activated as soon as the controller temperature reaches 55°C. Take a look at the diagram below to see how it is properly connected.
Note: If the pins are misaligned, a result of the fan spinning backwards (connected one pin over) or the fan running continuously (connector is upside down) will occur.
