Q1_Aircraft: Bellying up to the bar

All,
Probably by next week I'll be buying my engine and prop. I just
wanted to know what size and pitch prop others are using with a Q1. It
seems 48 to 52 inches is popular. I think when I allow 9' clearance
with the firewall perpendicular to earth, I would be 48 or 50'. I am
intested in the powerfin props. Does anyone have experience with them
on a Q1? I was thinking a 3 blade. The engine is the hexadyne P60,50
hp at 2300 rpm. Any advice about props would be appreciated.
Thanks
Dave R.

Dave,

What is the PSRU ratio?

Ryan,
PSRU is 2.5. Does that really matter, if I know the propeller rpm?
I'm just asking, for my own education. The ratio is not adjustable,
so the output is 2300 @ 5750 @ 60 HP.
Thanks
Dave
