I had a rotor once I do not remember who made it. But it was super nice
because it had 400 degrees of rotation.
the stops were both sides of north by 45 degrees. don't remember who
made it tho but that was NICE!!

That is why some set up their rotors to have the motor's zero degree setting aimed South, if most of the things they aim at are + / - North. That's not the case here, so I use the regular Zero = North arrangement. (Or invest in a rotor that can swing through 450 degrees...)
