Matt... the rental Arrow POH (in the airplane).. has information for both 2
blade and 3 blade prop installations from the factory... it has the limits
on the non-continuous operations in there.. and with a 3 blade prop
installed.. the limits should also be placarded and marked in red on the
tach..

Sounds like an incomplete installation... unless the STC that governs the
installation does not mention it... would be surprising..

The arrow performs nicely with a 3 bladed prop on an ILS approach..
configured and keeping the RPM as desired.. you need to practice the
approach speeds and "fly by the numbers".. screw up the configuration.. ie
needing idle power to get down to the glide slope and that prop really
complains... or when pulling the power during the flare after breaking out
at 200ft.

the power back.. it does vibrate as it comes down through that RPM
range..

Our tach was not remarked and there is no placarded prohibited range.
Ours vibrates from 2200 down to about 1200.
