        <div>Alan,</div><div>That is a very slick motor alright, but it needs a controller.  You know how I try to avoid electronic components whenever possible.  Also i am trying to keep the cost down by using parts that I already have.  I have a satellite dish actuator and I have a trolling motor on the shelf.  I am picking up the actuator today from the shop and bringing it home to tear down.  I am quite excited that it might be DC.</div><div>Hank</div><div><br></div>
