Yes, at Cabin fever you will see some amazing work.
Calling something "worlds smallest' is a big stretch. The V12 is, as
pointed out, not even an engine.
The radials mentioned are by George Luhrs. 5 Cylinder, 1/4" bore. He has
built a 1 cylinder, overhead valve 4 stroke with 1/8" bore. To hear it

Hucks built. He is doing the blower now and the build is fully detailed
Steve is a Mach user. The plans are available from him.
