WRT the weight...is that really true?
IME building liquid-cooled and air-cooled systems, the Liquid systems
are often lighter. Of course while glycol weighs more than air, usually
more aluminum is needed in an air-cooled system than in a liquid-cooled one.


I'd thoiught that weight was about the same. Frontal area (less
air resistance) favoured water-cooling but reliability favoured
radials.
