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.

I can get behind that; I like my builds to be aesthetically pleasing. But I tend to hide the wires in paracord.

Ooh, that's an interesting idea to try!

Is there a method to wire a brushless motor to an ESC so it spins in the required direction first time?

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.
