3 or 4 blade prop for ys fz 91?
I am planning to install a ys fz91 on a .60 Corsair, and for scale appearance I was thinking about using a 3-blade (or 4-blade).
Is this advisable? and if so, what size?
Thank you

Master Airscrew makes a 14x9 3 blade that should get you in the ballpark on 20%. You want to get 8000-9500 RPM out of the engine, 9000-9300 seems a happy place without getting excessive if you are just sport flying. If you are racing then the gloves come off and you'll wind it up tighter but longevity will suffer.
