O.S. engine MaX-37SZ-HRING Manual page 6

This is a high performance engine
designed for small-sized
controlled helicopters.
Since the mounting bolt pattern of the
engine as well as silencer is the same as
those of the 32SX-H, it can be directly
replaced with the 32SX-H and most of
other 32-39 size engines. This powerful
engine is suitable for sport flight as well
as 3D flight.
With some models, needle interferes the
body and working on the body to avoid
this would be required.
