Hey Gang,
In my ES, I find that I get a very limited air flow from my heating system.
I suspect
that that the problem may be that the cabin lacks an "exhaust" that lets the
air get
out. However, by the same token the overhead cooling vents provide a good
blast of air.
I am helping a new ES builder with his plane and we have installed a reverse
NACA
scoop  in the bottom of the tail. It is located near the rear access door.
It will be quite
a while before we know if this does the trick. Has anyone out there had a
similar
problem and found a solution?
