This medium duty steering rod set will work very well with your medium to larger nitro outboard boats. It is not recommended for Gas outboards. The rods are 3/16″ diameter solid aluminum for flexible strength that will take a moderate hit and not bend or collapse like tubing can. The easily adjustable length makes them simple to fit on nearly any boat. The ball joint fittings at both ends are the same quality as the slightly larger ones we use on the Heavy Duty set (#1030). Match this with the special steering arm on your Lawless Drive and whatever output arm you have on your servo. (Bar type is best).
