Thank you PT and Ray, I am not a member of a Tug specific forum. Though I am a member of Paddleducks and modelboatmayhem. The tug is a basic 2 channel with a sound unit and smoke generator.
I seem to be migrating to steam powered paddle boats and marine engines, I have acquired a great steam paddle engine from Bogstandard that was on ebay. The goal is to end up making my own engines.
