WLToys v939 Flight Controller

I received my v939 flight controller aka RX board. And I had to look up the motor direction to ensure I installed the board properly.

For those using this FlySky compatible flight controller, here’s an image of the board with the motor direction annotated as well as where the motor should be plugged into.

    For the motors is the positive on the inside or outmost connector please? I’m making one up from spares and no idea which way the polarity is. Thanks,

      The negative should be the outside. Positive on the inside pins of the connector.
