C & R doesn't care if it is for an aircraft.  In fact they are thinking about sending a rep to Oshkosh.  As far as rads go, "As big as possible and as thin as possible." makes sense to me.   Trouble is, in most aircraft, as  big as possible is not big enough so we have to compensate with additional thickness.   Jerry
