Okay, here is a real test of this groups aeronautical acumen.

On the front of my Glastar is a ground adjustable Ivo Magnum (3 blade).  The
"destructions" advise that it is adjustable from 30" to 90" pitch by turning
a large adjustment screw which twists a cam in each blade.  This screw has 5
turns stop to stop, or 12" per full turn of the screw.  The prop is
currently set at ~54" of pitch.  I ran the engine this morning to ~4500rpm
and 25" MAP.  While there was throttle left, the engine did not seem to want
to advance from there.
The plane was bouncing around like a caged animal...  This is new ( and
exciting) to someone used to C152s.

The test:
How would one determine the correct pitch for first flight and what is the
guesstimate of what that pitch should be?
