So I know that three phase motors will reverse direction when 2 wires are swapped round, or that the direction can be changed in software (such as BLHeli).

But is there a method to get it right first time, without doing something hacky like using alligator clips. Are the wires/pads usually in a standard order on the motors/ESC? Can the phases be worked out some other way?

    IMO, it looks better to have all motors wired to the ESCs in the same way and then just flip the direction of the required motors in BLHeliSuite. – ifconfig Jun 19 at 17:15
  • I can get behind that; I like my builds to be aesthetically pleasing. But I tend to hide the wires in paracord. – RJBulger Jun 19 at 21:04

    Ooh, that's an interesting idea to try! – ifconfig Jun 19 at 22:16

Without disassembling the motor, and figuring out how the ESC is designed, there is no other way then simply testing it.

From my experience, the motors spinning clockwise has usually been the ones that can be wired without crossing any wires and without having to reverse the direction. But that could just be a coincidence, so you should definitely not trust that it will always be like that, even if that might be the most common.

The simplest and fastest way to get the motors to spin the right way is usually to just solder all the wires so that it looks the best, and then reverse the direction in for example BLHeliSuite as needed.
