With its operating cylinders hung under the deck, the prominate feature of this Stirling model is a 4.75 inch dia. flywheel. A slot driven (Scotch Yoke) 90 degree con rod to the displacer cylinder sets up the phasing while its curvilinear travel commands an oscillating cylinder assembly used with a strait displacer push rod. A conventional vertical beam joins the power cylinder to the flywheel. http://www.youtube.com/watch?v=NWMHCIpZyng
