Default Prop Selection
Has anyone done any data on fixed pitch props for a 750# 160hp o320 RV-3? Catto says 66" by 76 or 78" for a two blade.

Good info...looks like 68x76 is the way to go. It came with a sterba 68x72, however it was not in good shape and would need some repair. Thanks Tony

I spent a week prepping an 0-320 powered -Three to go to Germany. (Heard it's in Italy now) It has a Catto 69/69 which worked well. I tested several props for Craig on my 150HP RV4 back in the day and his 69/69 worked well on my light Four.

Yup, Heinz sold it to Giulio, who's enjoying her in northern Italy, near Milan. Nice little plane!
