yes Raphael I chose the engine after reading and watching many reviews, apart from the swept volume being smaller than most of my other engines since I am building a diorama (1:24 th scale) and not a model boat the steam issue is not that important other than the physical limitations of the diorama but a 4" tubed boiler can be easily accommodated and should run this engine and a steam powered generator together with capacity to spare. A similar boiler to the one I made for my forge diorama
