Finn,
Not
intending to start a feud here, but it
was my understanding that there is less drag created by a stopped prop
compared
to a spinning prop. If this is true, and if your intention is to
maximize
your glide in the event of an engine out situation, then it seems that
a psru
would be an advantage over direct drive.

Prop
windmilling
2.176:1
will definitely
not windmill at pattern or glide speed for an RV-3 (about 100 mph).
Might make
a 1/3 turn and stop again if you point it down a bit. And that was with
an
engine that had rather low compression.
Tested several times over Clearwater Airpark.

Finn;
What prop
