I am always amused and amazed
when people bad mouth an aircooled aircraft engine. My ideal
would be an aircooled rotary with an oil cooled rotor and perhaps
water cooled end plates as they are hard to cool with air.

My std comment is - "water cooled airplanes make just
as much sense as air cooled submarines"   and you
can quote me.  :-)

Actually, when running auto conversions, some suboptimal
choices will have to be accepted.  The simplicity and
lightness of aircooled engines is great, but careful
competent design and testing is necessary, which is
not possible when converting.

Plus, heaters are a problem.
