Paul,
        Watching this hanging the rad under the fuselage thread with great
interest.  If a group buy to get a rad with fins placed in an optimum
orientation is a possibility why not integrate the oil cooler into the setup?

When I get time I'll research it some more. There is a heat exchanger
outfit in upstate NY that makes custom fin strips for rads. They also
braze the cores together as I recall.

Oil coolers may require heavier wall tubes and internal turbulators.
The stock Mazda oil cooler is the hot (cool?) tip for the foreseeable.
