think I've been told that the NACA works moderately well for the EZ types
on the ground because the proximity of the prop to the exit provides a good
low pressure to pull the air through the system. Can you comment on this
aspect of Jerry's proposed cooling scheme Bill? You wont have that going
for you. And your inlets are far enough back from the prop that you wont
see a lot of benefit from prop blast on the inlet side either.

  I sure understand the need to not compromise on the aesthetics of the
installation. I'm working on the same dilemma with my oil cooler
installation now.

  It will be interesting to see how this works for you. I wish you luck.

I agree. I think fans are a good idea for you Jerry.
