Andy is correct. Can this job be done by an RC model servo-motor? they are controlled by the pulse width, and are fairly accurate, often better than 1 or 2 percent of the output range. Typically half a turn range. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
