RE: how to connect a brushless motor to a speed controller
Just connect the blue wires to the motor wires in any order. If the motor spins the wrong way, switch the connections between two of the wires and the motor will change direction. You have a 50/50 chance of getting it right the first time!
You won't hurt anything by connecting the wires in any order - that's why the wires coming from speed controller are all one color.
Hope this helps,
