Some millitary two stroke drone engines are around 15 kg for half a litre.In my scheme there is already a great part of the crankshafting in the generators plus some crankcase and there is no cylinder heads.
Let us say 10kg for the Junkers parts and two times 4 kg for generators to make 30kW electricity.
