[TowerTalk] Rotor on AB577

[ChetMoore]

I did exactly what Jerry suggested.    One more thing,  Two of the Clips on 
the guy wires that came pre attached to the color coded guy wires on my unit 
broke on two different occasions.  I would recommend replacing those all of 
these clips with  stainless steel or brass clips or  cutting the original 
clips off , and use  a thimble and wire clamps
