Many at our club will agree with you on the Zenoah !
They are used in great numbers at our club because of their reliability.

Some also believe they have more power than advertised.
A good engine indeed.

I'm hoping that the DA-50, when broken in, will also be a great engine.
I like the compact size for fitting in cowling's without cutting for the carb.
My only wish is that the DA-50 had a longer nose so the cylinder sat back a little further.
When mine runs, its powerful.
