Paul,

I have an ES and installed the blower. In summer it is
an absolute necessity. The big fan in the front does
push some air into the duct, but the little fan in the
back does a much better job. The best testament I have
is that often while turning off the runway I have a
chorus shouting "Fan! Fan! Turn on the Fan!"

As to where to install it, have a look on my website
http://www.vhs2dvdfast.com/lancair/ to see where I put it.

Good luck and happy sanding.
