I was hoping you caught my smileys....
One thing I learned the hard way running APC props on ducted fan engines is to look for white stress marks on the prop blades near the hub. When they are near or over the safe rpm and you see the white stress marks, they usually throw a blade on the next flight. Ask me how I know that. Check your remaining blade.
How much does that engine unload in the air? I would guess 1000 or so??
