Engines have become a bit of focus point for me of late. Scratch built 1:8 scale to be exact.
I started with a Wright-Martin H3 which is a licence build of the Hispano-Suiza 8F bomber engine. This one has been converted for power boat racing by the Auto Engine Works of St. Paul, Minn. Quite a few were post WW1 when there were a lot of these engines surplus to requirements.
This engine is destined to be installed in a model boat eventually, which is why the water feed connection is incomplete.
Having enjoyed the Wright-Martin I decided to build the two engines fitted to the SE5a. The smaller brother of the H-S8F, the H-S8B, and the Wolseley Viper.
The H-S8B with the dreaded reduction gearbox that was so prone to failure.
And the Wolseley Viper, which may look very similar to the H-S but virtually every part is different in some way!
Both engines now form a little diorama of SE5a power plants.
The latest WIP is a Le Rhone 9C, which I hope to install in a 1:8 Sopwith Pup, if I ever get around to finishing the CAD model of that. I might just stop at a front fuselage though.
