A very simple solution to stop your props chewing on your motor wires.
Install them at the point on the arms where the prop bends down towards the arm from here on in when the prop strikes the arm you don’t slash the motor wires in a crash. Perfect for 4-in-1 ESCs and also really handy if your motor wire are a bit too short.
