Hey, Chris, I forgot to mention that the marker is attached to a springed door hinge. The hinge doesn't have quite enough strength to balance the marker, but I think once the outer pvc barrel is mounted, the marker will be just about balanced on the pivot point. Seems that a standard servo will work for now, I guess if I strip it out, I can just upgrade to a larger size.
