Lindberg Power Drive Unit R/C Twin Engine Drive System for Boats. A plug-in electric system designed for Lindberg R/C Boats and other boats of similar size. This system is designed to be used with Lindbergs 30″ Chris Craft Constellation, the 30″ Chris Craft Sportfisherman, the JFK PT-109 1/32 scale and the Blue Devil Destroyer.
I installed one of these kits in a Chris Craft Constellation and the power is extremely impressive. It is also an extremely simple installation with very straight forward instructions. When first offered, these kits retailed for $135.00 in most hobby stores. They are exceedingly rare to find in new condition.
