title_body: On a multirotor, how effective is braiding of power wires from the ESC to the BLDC Motor(s) in reducing or eliminate emf?
upvoted_answer: The braiding of motor wires should only be done for looks.  It looks cool and that's about it.  It may actually cause problems with smaller motors.  I once had braided motor wires on a brushless whoop size quad and the braiding of the wires caused the motors to behave erratically at start up.  Sometimes they would start spinning.  After removing the braids they started up perfectly every time.
