Hi All
Has anyone used one of these engines ?, if so what boiler size would you recommend to pair up with it.
Cheers
Mike

Bonjour Mike,
If you refer to this machine : https://www.youtube.com/watch?v=D9crWJ9gpEw (https://www.youtube.com/watch?v=D9crWJ9gpEw) I have just test it on air, already very powerful.
My friend Eric has two of them :]https://www.youtube.com/watch?v=V-SViVeUMx8 (https://www.youtube.com/watch?v=V-SViVeUMx8)
Based on my experience, I would suggest a 100 x 200 mm horizontal boiler to have about 35 minutes of autonomy at 2 bar/ 30 PSI without pump.

Good Evening rhavrane
Many thanks for your reply, it really looks a powerful engine and low boiler pressure.
I intend to put it in a "Kingston Mouldings"  yacht tender 1912 a scale of 1:10 which is 45" X 9.5"  which is currently under construction.
Regards
Mike
