Several weeks ago I posted a thread asking "besides the
cost of fuel , exactly what is the advantage ? I didn't get
any takers so presumed that apparently there are none .

The cost of fuel is not an issue here, ........it's prop size and
only prop size.

SO ,I now have a new OS 1.60 FX in the cowl of my GP Pitts
ARF .

I now ask the question again.

Is anyone flying this combo , and if so what prop are you
currently using ?

Regards and thanks anyway
