Paul,    Seeing the electric cooling fans on the Engineair reminds me of
a Cirrus VK30 that ' ate / shredded ' its electric fans.  Suppose it's
important on placement so high speed air doesn't drive the fan.  I don't
recall where the fans were located in the VK30.  For taxi ops one could
use a flap / duct to run the elec fan, and block it for high speed
cruise?  Or maybe its not necessary on
a tractor.  Just a thought that is probably covered in your
book.  Anxious to see how the K&L diffuser works on Tracys.

Those are Spal fans and they don't seem to be bothered by that.

If the diffuser is designed properly I think the flow is fairly slow,
even in a fast moving plane... (?)
