My Supra has one. Also a Celica I had ('85) and an '85 Corolla.
Most of the fans post 75 or so are plastic, one reason being weight and
the other being the flexability of plastic. I can't remember the last time
I saw a metal fan!

just because it's plastic does not mean it's flexible enough to "flatten
out" as if it's variable pitch. what mechanical properties do /you/
think "flexibility" gives the fan?

I don't know whether they were ever used as OEM fans, but my motorhead
brother was pretty fond of aftermarket "flex fans." If the plastic blade is
mounted to the hub by the leading edge, it's a good bet it is a flex fan. If
the blade is mounted by the whole root it is just another fan.

interesting - i've never seen a fan like that. seems kind of bizarre to
me since i can't see what would keep the blade pitched to improve
airflow when it was supposed to be working, but hey...

you should if you want the fan to move the freakin' air that you think
is cooling your engine!!! if the blades can adopt a position of least
resistance, they will. that means throughput will be minimal - totally
defeats their supposed purpose.

did you know that the outer extremity of a fan blade moves faster than
the bit nearest the hub? apparently these guys don't since it's the
same pitch for the whole blade!!! what a total p.o.s.
