Now I have mastered the black art of resizing pictures I will add some more of my latest project. I have had a few simple steam engines in the past & indeed worked on real steamships in an earlier life. This one has a lot of parts I do not recocgnise. There are a number of R/C linkages to various parts of this set-up including one to the valve between the cylinders, one to after the lubricator on the inlet manifold. Another to a valve controlling the gas supply. A pressure switch on top of the steam dome with a single pin connector. There is a bespoke water tank in the bow with high & low level sensors. Another sensor going into the firebox with a Futaba type connector.
