This one's not geared, it was replaced with an O-360

Full Prop if under 100MPH? not sure about why that one.. but I'm sure
the
idea of going to full prop (high RPM) when under 15in MP, you are most
likely below the "prop governing range" and want the best performance,
if
your under 15in MP you are either "throttled back" for descent, or very
high

Bad idea in geared engines to run the prop forward in descents. There's
always
a tiny amount of play in the gearbox. You don't want to spend a lot of
time
with the prop driving the engine.
