In the Head set-up there is a selection for Standard, High Speed and Ultra Speed. What is this?
This selection is only for customized units. Standard is what most people have and need (speed = 210 deg/sec). High Speed is a gearing change only to bring it up to 360 deg/sec. Ultra Speed is a more expensive, high-specialized option with gearing change, high voltage motor, and 36 VDC supply for speed up to 500 deg/sec. Ultra Speed is for auto racing and we will not sell this option without training the owner.
