       Additional details:

         High torque servo motors are used to produce the actions.

         The Mini-SSC is produced by Scott Edwards of Arizona and will control up to 8 servos at a time.

         Two Mini-SSC controllers will be included with each kit.   Please visit his site for more info on his

         controller board.       http://www.seetron.com/ssc.htm

         Connection to the computer:

         is included in the price.  This is Hobbyist V5 .0  and is supplied on a CD.   This software allows you

         to set up a sequence of actions (as long as you want) for up to 64 servos and to associate a wave

         file with each one.  You can play the resulting sequence once or many times or repeatedly.

         Please visit     http://www.brookshiresoftware.com/           for more information of this package.

         Size:   The arm is basically life-sized.   Weight is about 10 pounds.
