Thanks Al,
That's good info.
If I remember right the argument was the fan blade
being close to the rad, would restrict flow when not in use, and to
allow the blade to freewheel would kill the fan bearings.
It's obvious that a fan on the ground is quite an
advantage.
I always felt that a fan that could swing away, out
of the air flow, would be ideal. However having the room to do that would be
problematic.

I believe Rino said he had a fan
on the oil cooler, which I feel would be restrictive in aviation use, from
what I've heard. Might be good for taxiing etc.

George;
I added a fan
behind the coolant radiator; and found it had no detrimental effect in
flight, and made a big improvement in cooling on the ground. This is
on a pusher (Velocity) with a ram
scoop. I expect it could make a difference depending on what type of
fan and the effectiveness of the intake scoop.
