I've seen similar questions asked before, but they're all about making a fighter bank based on player input. I'm trying to make my enemy fighters bank. Here's what I've got so far:

    var relativePos = fightertarget.position - transform.position;
var fighterRotation = Quaternion.Slerp (transform.rotation, Quaternion.LookRotation(relativePos), TurnRate * Time.deltaTime);

//banking on turns! Somehow!


transform.rotation = fighterRotation ;
transform.Translate(Vector3.forward *0.1);

Which is pretty much a basic homing script. I can't really get my head round Quaternions (yet) so it's kicking my backside. I've tried numerous different approaches, but nothing has worked so far.
