I built a model of the Creole Queen.54" length by 14 beam. I used the motor and drive from one wheel of a battery powered kids car, and the speed control and the reverse switch from a variable speed drill. I drive the paddle wheel fron two eccentrics set 90 degrees apart off the axle shaft from the little car with two rods to the eccentrics on the paddle. I used HO railroad tracks for the railings, and everything else is from balsa or pine. It looks real nice on the water with the rods moving back and forth. Ed
