Cont Servo Question

I am sure this is someplace ( I can find it with search)

I learning to use the tracking for ez v4 and I was wondering if is is possible to use the 360 servo to have cam track in a circle? I have been trying, but it seems once the cam picks up something it just spins the servo ( with no stops) with no real regard to anything and does not behave like the regular servo with tracking. Is this something that is just a result of the 360 servo or is it something I can fix?
