[TR] TR Fan Pitch

[Geo & Kathleen Hahn]

Some fans with lots of pitch flex and flatten out at high speed... don't 
know if this is the case with the TR plastic fans but, as noted, tweaking 
the old metal fan seems dicey.

I somehow ended up with a TR4 fan (square tip) on my TR3A (would have had 
the rounded tip) which may perhaps provide some small improvement.
