Smallest Size Rolls Royce Engine at the Archives ??

[MustafaUmutSarac]

I can think some of you are the experts on rolls royce engines. What is the smallest size rolls royce engine at marine or automobile or experimental or army archives ? For example , did rolls royce ever designed a model car, model ship or model aircraft engine ? This would be a very fun project to work on ! And small diesel marine engine copy could be used to propel my boat.

I think the Austin Champ had either a Rolls Royce designed engine, or they might have built the engines. I am not sure if they were Diesel or petrol. I am almost sure they were 4 cylinder. All this info is from memory so I could be completely wrong!

Hi,
Back in 2015 there was a build series for a 1/4 scale RR Merlin engine here.
https://www.homemodelenginemachinist.com/threads/quarter-scale-merlin-v-12.24153/It was from a commercial set of castings which don't seem to be available any more. The guy who built it did really good work - much better than I could manage and the build series is worth a look if you haven't seen it.
Regards,
Alan
