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.

Thank you. I am not into racing, and so longevity is much more important to me than speed...
