Oops! Forgot to mention one point that is important.  Flat plate 
radiators were tried on some pre-WWII planes.  They were found to be 
very efficient and weight effective, especially where there surface area 
was used as part of the airplane structure. Wing leading edge, for 
example.  The problem was maintenance.  One small rock chip would just 
ruin your whole day.

Also, on the cooling tube idea.  I'm considering locating my radiators 
in the rear, which will require routing some tube back there.  If I used 
this stuff, then I could route cool air over it and possibly use a 
smaller radiator.

BTW, it is detailed on one of my web pages, but I'm planning on using a 
AC condensor from a Nissan Altima.  It has a large frontal area, but is 
only 1" thick.  My only concern is that the flattened runner tubes will 
not pass enough water.
