RE: 3-blade propellers

I think it depends on the airplane too.
I found a 14x7 2 blade gave me the best performance with my OS 91FS
which would equate to a 13X7 3 blade.
all this on a 1/4 scale RV-4
Now BigTim states best performance with a 14X7 3 blade prop on warbirds.
I have been a fan of Graupner props since I flew one last summer.
They have a 12.5X7 that might be a good match for your engine.

This is a USA distributor, the Graupner props are made in Germany here is their website:
